The Slimey Limey shut the heavy door, and the sounds from the main room were muted. He waved Slip to a chair and made a show of mixing them some drinks. "They're all simulators, aren't they?" Slip said quietly. "Uh?" The Limey broke off his stream of chatter and shook his head glumly. "Not all. I've recruited four or five apprentices. They do their best to make the place look thriving and occupied. You may have noticed various improvements in our security."
   "It looks stronger, but it's more appearance than fact."
   Slimey shrugged. "I really didn't expect it to fool the likes of you."
   Mr. Slippery leaned forward. "Who's left from the old group, Slimey?"
   "DON's gone. The Mailman is gone. Wiley J. Bastard shows up a couple of times a month, but he's not much fun anymore. I think Erythrina's still on the System, but she hasn't come by. I thought you were gone until today."
   "What about Robin Hood?"
   "Gone."
   That accounted for all the top talents. Virginia the Frog hadn't been giving away all that much when she excused him from betraying the Coven. Slip wondered if there was any hint of smugness in the frog's fixed and lipless smile. "What happened?"
   The other sighed. "There's a depression on down in the real world, in case you hadn't noticed; and it's being blamed on us vandals.
   " — I know, that could scarcely explain Robin's disappearance, only the lesser ones. Slip, I think most of our old friends are either dead Truly Dead — or very frightened that if they come back into this Plane, they will become Truly Dead."
   This felt very much like history repeating itself. "How do you mean?"
   The Limey leaned forward. "Slip, it's quite obvious the government's feeding us lies about what caused the depression. They say it was a combination of programming errors and the work of 'vandals.' We know that can't be true. No ordinary vandals could cause that sort of damage. Right after the crash, I looked at what was left of the Feds' data bases. What — ever ripped things up was more powerful than any vandal. … And I've spoken with — p'raps I should say interrogated Wiley. I think what we see in the real world and on this plane is in fact the wreckage of a bloody major war."
   "Between?"
   "Creatures as far above me as I am above a chimp. The names we know them by are the Mailman, Erythrina… and just possibly Mr. Slippery."
   "Me?" Slip tensed and sent out probes along the communications links which he perceived had created the image before him. Even though on a leash, Mr. Slippery was far more powerful than any normal warlock, and it should have been easy to measure the power of this potential opponent. But the Limey was a diffuse, almost nebulous presence. Slip couldn't tell if he were facing an opponent in the same class as himself; in fact, he had no clear idea of the other's strength, which was even more ominous.
   The Limey didn't seem to notice. "That's what I thought. Now I doubt it. I wager you were used like Wiley and possibly DON — by the other combatants. And I see that now you're in someone's thrall." His finger stabbed at the yellow-eyed frog on Mr. Slippery's shoulder, and a sparkle of whiskey flew into the creature's face. Virginia — or whoever was controlling the beast — didn't know what to do, and the frog froze momentarily, then recovered its wits and emitted a pale burst of flame.
   The Limey laughed. "But it's no one very competent. The Feds is my guess. What happened? Did they sight your True Name, or did you just sell out?"
   "The creature's my familiar, Slimey. We all have our apprentices. If you really believe we're the Feds, why did you let us in?"
   The other shrugged. "Because there are enemies and enemies, Slip. Beforetime, we called the government the Great Enemy. Now I'd say they are just one in a pantheon of nasties. Those of us who survived the crash are a lot tougher, a lot less frivolous. We don't think of this as all a wry game anymore. And we're teaching our apprentices a lot more systematically. It's not near so much fun. Now when we talk of traitors in the Coven, we mean real, life-and-death treachery.
   "But it's necessary. When it comes to it, if we little people don't protect ourselves, we're going to be eaten up by the government or… certain other creatures I fear even more."
   The frog shifted restively on Mr. Slippery's shoulder, and he could imagine Virginia getting ready to deliver some speech on the virtue of obeying the laws of society in order to reap its protection. He reached across to pat its cold and pimply back; now was not the time for such debate.
   "You had one of the straightest heads around here, Slip. Even if you aren't one of us anymore, I don't reckon you're an absolute enemy: You and your … friend may have certain interests in common with us. There are things you should know about — if you don't already. An' p'raps there'll be times you'll help us similarly."
   Slip felt the Federal tether loosen. Virginia must have convinced her superiors that there was actually help to be had here. "Okay. You're right. There was a war. The Mailman was the enemy. He lost and now we're trying to put things back together."
   "Ah, that's just it, old man. I don't think the war is over . True, all that remains of the Mailman's constructs are 'craterfields' spread through the government's program space. But something like him is still very much alive." He saw the disbelief in Mr. Slippery's face. "I know, you an' your friends are more powerful than any of us. But there are many of us — not just in the Coven — and we have learned a lot these past ten weeks. There are signs, so light an' fickle you might call 'em atmosphere, that tell us something like the Mailman is still alive. It doesn't quite have the texture of the Mailman, but it's there."
   Mr. Slippery nodded. He didn't need any special explanations of the feeling. Damn! If I weren't on a leash, I would have seen all this weeks ago, instead of finding it out secondhand . He thought back to those last minutes of their descent from godhood and felt a chill. He knew what he must ask now, and he had a bad feeling about what the answer might be. Somehow he had to prevent Virginia from hearing that answer. It would be a great risk, but he still had a few tricks he didn't think DoW knew of. He probed back along the links that went to Arcata and D.C., feeling the interconnections and the redundancy checks. If he was lucky, he would not have to alter more than a few hundred bits of the information that would flow down to them in the next few seconds. "So who do you think is behind it?"
   "For a while, I thought it might be you. Now I've seen you and, uh, done some tests, I know you're more powerful than in the old days and probably more powerful than I am now, but you're no superman.
   "Maybe I'm in disguise."
   "Maybe, but I doubt it." The Limey was coming closer to the critical words that must be disguised. Slip began to alter the redundancy bits transmitted through the construct of the frog. He would have to fake the record both before and after those words if the deception was to escape detection completely. "No, there's a certain style to this presence. A style that reminds me of our old friend, REorbyitnh rHio— noad." The name he said, and the name Mr. Slippery heard, was "Erythrina." The name blended imperceptibly in its place, the name the frog heard, and reported, was "Robin Hood."
   "Hmm, possible. He always seemed to be power hungry." The Limey's eyebrows went up fractionally at the pronoun "he." Besides, Robin had been a fantastically clever vandal, not a power grabber. Slimey's eyes flickered toward the frog, and Mr. Slippery prayed that he would play along. "Do you really think this is as great a threat as the Mailman?"
   "Who knows? The presence isn't as widespread as the Mailman's, and since the crash no more of us have disappeared. Also, I'm not sure that… he… is the only such creature left. Perhaps the original Mailman is still around."
   And you can't decide who it is that I'm really trying to fool, can you? The discussion continued for another half-hour, a weird three-way fencing match with just two active players. On the one hand, he and the Limey were trying to communicate past the frog, and on the other, the Slimey Limey was trying to decide if perhaps Slip was the real enemy and the frog a potential ally. The hell of it was, Mr. Slippery wasn't sure himself of the answer to that puzzle.
   Slimey walked him out to the drawbridge. For a few moments, they stood on the graven ceramic plating and spoke. Below them, Alan paddled back and forth, looking up at them uneasily. The mist was a light rain now, and a constant sizzling came from the molten rock.
   Finally Slip said, "You're right in a way, Slimey. I am someone's thrall. But I will look for Robin Hood. If you're right, you've got a couple of new allies. If he's too strong for us, this might be the last you see of me."
   The Slimey Limey nodded, and Slip hoped he had gotten the real message: He would take on Ery all by himself. "Well then, let's hope this ain't good-bye, old man." Slip walked back down into the valley, aware of the Limey's not unsympathetic gaze on his back.
   How to find her, how to speak with her? And survive the experience, that is. Virginia had forbidden him — literally on pain of death — from meeting with Ery on this plane. Even if he could do so, it would be a deadly risk for other reasons. What had Ery been doing in those minutes she dallied, when she had fooled him into descending back to the human plane before her? At the time, he had feared it was a betrayal. Yet he had lived and had forgotten the mystery. Now he wondered again. It was impossible for him to understand the complexity of those minutes. Perhaps she had weakened herself at the beginning to gull him into starting the descent, and perhaps then she hadn't been quite strong enough to take over. Was that possible? And now she was slowly, secretly building back her powers, just as the Mailman had done? He didn't want to believe it, and he knew if Virginia heard his suspicions, the Feds would kill her immediately. There would be no trial, no deep investigation.
   Somehow he must get past Virginia and confront Ery — confront her in such a way that he could destroy her if she were a new Mailman. And there is a way! He almost laughed: it was absurd and absurdly simple, and it was the only thing that might work. All eyes were on this plane, where magic and power flowed easily to the participants. He would attack from beneath, from the lowly magicless real world!
   But there was one final act of magic he must slip past Virginia, something absolutely necessary for a real world confrontation with Erythrina.
   He had reached the far ridge and was starting down the hillside that led to the swamps. Even preoccupied, he had given the right signs flawlessly. The guardian sprites were not nearly so vigilant toward contructs moving away from the castle. As the wet brush closed in about them, the familiar red and black spider — or its cousin — swung down from above.
   "Beware, beware," came the tiny voice. From the flecks of gold across its abdomen, he knew the right response: left hand up and flick the spider away. Instead Slip raised his right hand and struck at the creature.
   The spider hoisted itself upward, screeching faintly, then dropped toward Slip's neck — to land squarely on the frog. A free-for-all erupted as the two scrambled across the back of his neck, pale flame jousting against venom. Even as he moved to save the frog, Mr. Slippery melted part of his attention into a data line that fed a sporting goods store in Montreal. An order was placed and later that day a certain very special package would be in the mail to the Boston International Rail Terminal.
   Slip made a great show of dispatching the spider, and as the frog settled back on his shoulder, he saw that he had probably fooled Virginia. That he had expected. Fooling Ery would be much the deadlier, chancier thing.
 
   If this afternoon were typical, then July in Providence must be a close approximation to Hell. Roger Pollack left the tube as it passed the urbapt block and had to walk nearly four hundred meters to get to the tower he sought. His shirt was soaked with sweat from just below the belt line right up to his neck. The contents of the package he had picked up at the airport train station sat heavily in his right coat pocket, tapping against his hip with every step, reminding him that this was high noon in more ways than one.
   Pollack quickly crossed the blazing concrete plaza and walked along the edge of the shadow that was all the tower cast in the noonday sun. All around him the locals swarmed, all ages, seemingly unfazed by the still, moist, hot air. Apparently you could get used to practically anything.
   Even an urbapt in summer in Providence. Pollack had expected the buildings to be more depressing. Workers who had any resources became data commuters and lived outside the cities. Of course, some of the people here were dataset users too and so could be characterized as data commuters. Many of them worked as far away from home as any exurb dweller. The difference was that they made so little money (when they had a job at all) that they were forced to take advantage of the economies of scale the urbapts provided.
   Pollack saw the elevator ahead but had to detour around a number of children playing stickball in the plaza. The elevator was only half-full, so a wave from him was all it took to keep it grounded till he could get aboard.
   No one followed him on, and the faces around him were disinterested and entirely ordinary. Pollack was not fooled. He hadn't violated the letter of Virginia's law; he wasn't trying to see Erythrina on the data net. But he was going to see Debby Charteris, which came close to being the same thing. He imagined the Feds debating with themselves, finally deciding it would be safe to let the two godlings get together if it were on this plane where the State was still the ultimate, all-knowing god. He and Debby would be observed. Even so, he would somehow discover if she were the threat the Limey saw. If not, the Feds would never know of his suspicions. But if Ery had betrayed them all and meant to set herself up in place of — or in league with — the Mailman, then in the next few minutes one of them would die.
 
   The express slid to a stop with a deceptive gentleness that barely gave a feeling of lightness. Pollack paid and got off.
   Floor 25 was mainly shopping mall. He would have to find the stairs to the residential apts between Floors 25 and 35. Pollack drifted through the mall. He was beginning to feel better about the whole thing. I'm still alive, aren't I? If Ery had really become what the Limey and Slip feared, then he probably would have had a little "accident" before now. All the way across the continent he sat with his guts frozen, thinking how easy it would be for someone with the Mailman's power to destroy an air transport, even without resorting to the military's lasers. A tiny change in navigation or traffic-control directions, and any number of fatal incidents could be arranged. But nothing had happened, which meant that either Ery was innocent or that she hadn't noticed him. (And that second possibility was unlikely if she were a new Mailman. One impression that remained stronger than any other from his short time as godling was the omniscience of it all.) It turned out the stairs were on the other side of the mall, marked by a battered sign reminiscent of old-time highway markers: FOOTS> 26-30. The place wasn't really too bad, he supposed, eyeing the stained but durable carpet that covered the stairs. And the hallways coming off each landing reminded him of the motels he had known as a child, before the turn of the century. There was very little trash visible, the people moving around him weren't poorly dressed, and there was only the faintest spice of disinfectant in the air. Apt module 28355, where Debbie Charteris lived, might be high-class. It did have an exterior view, he knew that. Maybe Erythrina — Debbie — liked living with all these other people. Surely, now that the government was so interested in her, she could move anywhere she wished.
   But when he reached it, he found floor 28 no different from the others he had seen: carpeted hall-way stretching away forever beneath dim lights that showed identical module doorways dwindling in perspective. What was Debbie/Erythrina like that she would choose to live here?
   "Hold it." Three teenagers stepped from behind the slant of the stairs. Pollack's hand edged toward his coat pocket. He had heard of the gangs. These three looked like heavies, but they were well and conservatively dressed, and the small one actually had his hair in a braid. They wanted very much to be thought part of the establishment.
   The short one flashed something silver at him. "Building Police." And Pollack remembered the news stories about Federal Urban Support paying youngsters for urbapt security: "A project that saves money and staff, while at the same time giving our urban youth an opportunity for responsible citizenship."
   Pollack swallowed. Best to treat them like real cops. He showed them his id. "I'm from out of state. I'm just visiting."
   The other two closed in, and the short one laughed. "That's sure. Fact, Mr. Pollack, Sammy's little gadget says you're in violation of Building Ordinance." The one on Pollack's left waved a faintly buzzing cylinder across Pollack's jacket, then pushed a hand into the jacket and withdrew Pollack's pistol, a lightweight ceramic slug — gun perfect for hunting hikes — and which should have been perfect for getting past a building's weapon detectors.
   Sammy smiled down at the weapon, and the short one continued, "Thing you didn't know, Mr. Pollack, is Federal law requires a metal tag in the butt of these cram guns. Makes 'em easy to detect." Until the tag was removed. Pollack suspected that somehow this incident might never be reported. The three stepped back, leaving the way clear for Pollack. "That's all? I can go?"
   The young cop grinned. "Sure. You're out-of-towner. How could you know?"
   Pollack continued down the hall. The others did not follow. Pollack was fleetingly surprised: maybe the FUS project actually worked. Before the turn of the century, goons like those three would have at least robbed him. Instead they behaved something like real cops.
   Or maybe
   — and he almost stumbled at this new thought — they all work for Ery now . That might be the first symptom of conquest: the new god would simply become the government. And he — the last threat to the new order — was being granted one last audience with the victor.
   Pollack straightened and walked on more quickly. There was no turning back now, and he was damned if he would show any more fear. Besides, he thought with a sudden surge of relief, it was out of his control now. If Ery was a monster, there was nothing he could do about it; he would not have to try to kill her. If she were not, then his own survival would be proof, and he need think of no complicated tests of her innocence.
   He was almost hurrying now. He had always wanted to know what the human being beyond Erythrina was like; sooner or later he would have had to do this anyway. Weeks ago he had looked through all the official directories for the state of Rhode Island, but there wasn't much to find: Linda and Deborah Charteris lived at 28355 Place on 4448 Grosvenor Row. The public directory didn't even show their "interests and occupations."
   28313, 315, 317 ….
   His mind had gone in circles, generating all the things Debby Charteris might turn out to be. She would not be the exotic beauty she projected in the Other Plane. That was too much to hope for; but the other possibilities vied in his mind. He had lived with each, trying to believe that he could accept whatever turned out to be the case:
   Most likely, she was a perfectly ordinary looking person who lived in an urbapt to save enough money to buy high-quality processing equipment and rent dense comm lines. Maybe she wasn't good-looking, and that was why the directory listing was relatively secretive.
   Almost as likely, she was massively handicapped. He had seen that fairly often among the warlocks whose True Names he knew. They had extra medical welfare and used all their free money for equipment that worked around whatever their problem might be — paraplegia, quadriplegia, multiple sense loss. As such, they were perfectly competitive on the job market, yet old prejudices often kept them out of normal society. Many of these types retreated into the Other Plane, where one could completely control one's appearance.
   And then, since the beginning of time, there had been the people who simply did not like reality, who wanted another world, and if given half a chance would live there forever. Pollack suspected that some of the best warlocks might be of this type. Such people were content to live in an urbapt, to spend all their money on processing and life-support equipment, to spend days at a time in the Other Plane, never moving, never exercising their real world bodies. They grew more and more adept, more and more knowledgeable — while their bodies slowly wasted. Pollack could imagine such a person becoming an evil thing and taking over the Mailman's role. It would be like a spider sitting in its web, its victims all humanity. He remembered Ery's contemptuous attitude on learning he never used drugs to maintain concentration and so stay longer in the Other Plane. He shuddered.
   And there, finally, and yet too soon, the numbers 28355 stood on the wall before him, the faint hall light glistening off their bronze finish. For a long moment, he balanced between the fear and the wish. Finally he reached forward and tapped the door buzzer.
   Fifteen seconds passed. There was no one nearby in the hall. From the corner of his eye, he could see the "cops" lounging by the stairs. About a hundred meters the other way, an argument was going on. The contenders rounded the faraway corner and their voices quieted, leaving him in near silence.
   There was a click, and a small section of the door became transparent, a window (more likely a holo) on the interior of the apt. And the person beyond that view would be either Deborah or Linda Charteris.
   "Yes?" The voice was faint, cracking with age. Pollack saw a woman barely tall enough to come up to the pickup on the other side. Her hair was white, visibly thin on top, especially from the angle he was viewing.
   "I'm… I'm looking for Deborah Charteris."
   "My granddaughter. She's out shopping. Down-stairs in the mall, I think." The head bobbed, a faintly distracted nod.
   "Oh. Can you tell me — " Deborah, Debby. It suddenly struck him what an old-fashioned name that was, more the name of a grandmother than a granddaughter. He took a quick step to the door and looked down through the pane so that he could see most of the other's body. The woman wore an old-fashioned skirt and blouse combination of some brilliant red material.
   Pollack pushed his hand against the immovable plastic of the door. "Ery, please. Let me in."
   The pane blanked as he spoke, but after a moment the door slowly opened. "Okay." Her voice was tired, defeated. Not the voice of a god boasting victory.
   The interior was decorated cheaply and with what might have been good taste except for the garish excesses of red on red. Pollack remembered reading somewhere that as you age, color sensitivity decreases. This room might seem only mildly bright to the person Erythrina had turned out to be.
   The woman walked slowly across the tiny apt and gestured for him to sit. She was frail, her back curved in a permanent stoop, her every step considered yet tremulous. Under the apt's window, he noticed an elaborate GE processor system. Pollack sat and found himself looking slightly upward into her face.
   "Slip — or maybe I should call you Roger here-you always were a bit of a romantic fool." She paused for breath, or perhaps her mind wandered. "I was beginning to think you had more sense than to come out here, that you could leave well enough alone."
   "You … you mean, you didn't know I was coming?" The knowledge was a great loosening in his chest.
   "Not until you were in the building." She turned and sat carefully upon the sofa.
   "I had to see who you really are," and that was certainly the truth. "After this spring, there is no one the likes of us in the whole world."
   Her face cracked in a little smile. "And now you see how different we are. I had hoped you never would and that someday they would let us back together on the Other Plane…. But in the end, it doesn't really matter." She paused, brushed at her temple, and frowned as though forgetting something, or remembering something else.
   "I never did look much like the Erythrina you know. I was never tall, of course, and my hair was never red. But I didn't spend my whole life selling life insurance in Peoria, like poor Wiley."
   "You… you must go all the way back to the beginning of computing."
   She smiled again, and nodded just so, a mannerism Pollack had often seen on the Other Plane."Almost, almost. Out of high school, I was a keypunch operator. You know what a keypunch is?"
   He nodded hesitantly, visions of some sort of machine press in his mind.
   "It was a dead — end job, and in those days they'd keep you in it forever if you didn't get out under your own power. I got out of it and into college quick as I could, but at least I can say I was in the business during the stone age. After college, I never looked back; there was always so much happening. In the Nasty Nineties, I was on the design of the ABM and FoG control programs. The whole team, the whole of DoD for that matter, was trying to program the thing with procedural languages; it would take 'em a thousand years and a couple of wars to do it that way, and they were beginning to realize as much. I was responsible for getting them away from CRTs, for getting into really interactive EEG programming — what they call portal programming nowadays. Sometimes … sometimes when my ego needs a little help, I like to think that if I had never been born, hundreds of millions more would have died back then, and our cities would be glassy ponds today.
   "… And along the way there was a marriage …" her voice trailed off again, and she sat smiling at memories Pollack could not see.
   He looked around the apt. Except for the processor and a fairly complete kitchenette, there was no special luxury. What money she had must go into her equipment, and perhaps in getting a room with a real exterior view. Beyond the rising towers of the Grosvenor complex, he could see the nest of comm towers that had been their last-second salvation that spring. When he looked back at her, he saw that she was watching him with an intent and faintly amused expression that was very familiar.
   "I'll bet you wonder how anyone so daydreamy could be the Erythrina you knew in the Other Plane." "Why, no," he lied. "You seem perfectly lucid to me."
   "Lucid, yes. I am still that, thank God. But I know — and no one has to tell me — that I can't support a train of thought like I could before. These last two or three years, I've found that my mind can wander, can drop into reminiscence, at the most inconvenient times. I've had one stroke, and about all 'the miracles of modern medicine' can do for me is predict that it will not be the last one.
   "But in the Other Plane, I can compensate. It's easy for the EEG to detect failure of attention. I've written a package that keeps a thirty-second backup; when distraction is detected, it forces attention and reloads my short-term memory. Most of the time, this gives me better concentration than I've ever had in my life. And when there is a really serious wandering of attention, the package can interpolate for a number of seconds. You may have noticed that, though perhaps you mistook it for poor communications coordination."
   She reached a thin, blue-veined hand toward him. He took it in his own. It felt so light and dry, but it returned his squeeze. "It really is me — Ery — inside, Slip."
   He nodded, feeling a lump in his throat.
   "When I was a kid, there was this song, something about us all being aging children. And it's so very, very true. Inside I still feel like a youngster. But on this plane, no one else can see…"
   "But I know, Ery. We knew each other on the Other Plane, and I know what you truly are. Both of us are so much more there than we could ever be here." This was all true: even with the restrictions they put on him now, he had a hard time understanding all he did on the Other Plane. What he had become since the spring was a fuzzy dream to him when he was down in the physical world. Sometimes he felt like a fish trying to imagine what a man in an airplane might be feeling. He never spoke of it like this to Virginia and her friends: they would be sure he had finally gone crazy. It was far beyond what he had known as a warlock. And what they had been those brief minutes last spring had been equally far beyond that.
   "Yes, I think you do know me, Slip. And we'll be … friends as long as this body lasts. And when I'm gone — " "I'll remember; I'll always remember you, Ery." She smiled and squeezed his hand again. "Thanks. But that's not what I was getting at…. " Her gaze drifted off again. "I figured out who the Mailman was and I wanted to tell you."
   Pollack could imagine Virginia and the other DoW eavesdroppers hunkering down to their spy equipment. "I hoped you knew something." He went on to tell her about the Slimey Limey's detection of Mailman — like operations still on the System. He spoke carefully, knowing that he had two audiences.
   Ery — even now he couldn't think of her as Debby — nodded. "I've been watching the Coven. They've grown, these last months. I think they take themselves more seriously now. In the old days, they never would have noticed what the Limey warned you about. But it's not the Mailman he saw, Slip."
   "How can you be sure, Ery? We never killed more than his service programs and his simulators-like DON.MAC. We never found his True Name. We don't even know if he's human or some science-fictional alien."
   "You're wrong, Slip. I know what the Limey saw, and I know who the Mailman is — or was," she spoke quietly, but with certainty. "It turns out the Mailman was the greatest cliche of the Computer Age, maybe of the entire Age of Science."
   "Huh?"
   "You've seen plenty of personality simulators in the Other Plane. DON.MAC — at least as he was rewritten by the Mailman — was good enough to fool normal warlocks. Even Alan, the Coven's elemental, shows plenty of human emotion and cunning." Pollack thought of the new Alan, so ferocious and intimidating. The Turing T-shirt was beneath his dignity now. "Even so, Slip, I don't think you've ever believed you could be permanently fooled by a simulation, have you?"
   "Wait. Are you trying to tell me that the Mailman was just another simulator? That the time lag was just to obscure the fact that he was a simulator? That's ridiculous. You know his powers were more than human, almost as great as ours became." "But do you think you could ever be fooled?" "Frankly, no. If you talk to one of those things long enough, they display a repetitiveness, an inflexibility that's a giveaway. I don't know; maybe someday there'll be programs that can pass the Turing test. But whatever it is that makes a person a person is terribly complicated. Simulation is the wrong way to get at it, because being a person is more than symptoms. A program that was a person would use enormous data bases, and if the processors running it were the sort we have now, you certainly couldn't expect real-time interaction with the outside world." And Pollack suddenly had a glimmer of what she was thinking.
   "That's the critical point, Slip: if you want real-time interaction . But the Mailman — the sentient, conversational part — never did operate real time. We thought the lag was a communications delay that showed the operator was off-planet, but really he was here all the time. It just took him hours of processing time to sustain seconds of self-awareness."
   Pollack opened his mouth, but nothing came out. It went against all his intuition, almost against what religion he had, but it might just barely be possible. The Mailman had controlled immense resources. All his quick time reactions could have been the work of ordinary programs and simulators like DON.MAC. The only evidence they had for his humanity were those teleprinter conversations where his responses were spread over hours.
   "Okay, for the sake of argument, let's say it's possible. Someone, somewhere had to write the original Mailman. Who was that?"
   "Who would you guess? The government, of course. About ten years ago. It was an NSA team trying to automate system protection. Some brilliant people, but they could never really get it off the ground. They wrote a developmental kernel that by itself was not especially effective or aware. It was designed to live within large systems and gradually grow in power and awareness, independent of what policies or mistakes the operators of the system might make.
   "The program managers saw the Frankenstein analogy — or at least they saw a threat to their personal power — and quashed the project. In any case, it was very expensive. The program executed slowly and gobbled incredible data space."
   "And you're saying that someone conveniently left a copy running all unknown?"
   She seemed to miss the sarcasm. "It's not that unlikely. Research types are fairly careless-outside of their immediate focus. When I was in FoG, we lost thousands of megabytes 'between the cracks' of our data bases. And back then, that was a lot of memory. The development kernel is not very large. My guess is a copy was left in the system. Remember, the kernel was designed to live untended if it ever started executing. Over the years it slowly grew — both be — cause of its natural tendencies and because of the increased power of the nets it lived in."
   Pollack sat back on the sofa. Her voice was tiny and frail, so unlike the warm, rich tones he remembered from the Other Plane. But she spoke with the same authority.
   Debby's — Erythrina's — pale eyes stared off beyond the walls of the apt, dreaming. "You know, they are right to be afraid," she said finally. "Their world is ending. Even without us, there would still be the Limey, the Coven — and someday most of the human race."
   Damn. Pollack was momentarily tongue-tied, trying desperately to think of something to mollify the threat implicit in Ery's words. Doesn't she understand that DoW would never let us talk unbugged? Doesn't she know how trigger-happy scared the top Feds must be by now? But before he could say anything, Ery glanced at him, saw the consternation in his face, and smiled. The tiny hand patted his. "Don't worry, Slip. The Feds are listening, but what they're hearing is tearful chitchat — you overcome to find me what I am, and me trying to console the both of us. They will never know what I really tell you here. They will never know about the gun the local boys took off you."
   "What?"
   "You see, I lied a little. I know why you really came. I know you thought that I might be the new monster. But I don't want to lie to you anymore. You risked your life to find out the truth, when you could have just told the Feds what you guessed." She went on, taking advantage of his stupefied silence. "Did you ever wonder what I did in those last minutes this spring, after we surrendered — when I lagged behind you in the Other Plane?
   "It's true, we really did destroy the Mailman; that's what all that unintelligible data space we plowed up was. I'm sure there are copies of the kernel hidden here and there, like little cancers in the System, but we can control them one by one as they appear.
   "I guessed what had happened when I saw all that space, and I had plenty of time to study what was left, even to trace back to the original research project. Poor little Mailman, like the monsters of fiction he was only doing what he had been designed to do. He was taking over the System, protecting it from everyone — even its owners. I suspect he would have announced himself in the end and used some sort of nuclear blackmail to bring the rest of the world into line. But even though his programs had been running for several years, he had only had fifteen or twenty hours of human type self-awareness when we did him in. His personality programs were that slow. He never attained the level of consciousness you and I had on the System.
   "But he really was self-aware, and that was the triumph of it all. And in those few minutes, I figured out how I could adapt the basic kernel to accept any input personality. … That is what I really wanted to tell you."
   "Then what the Limey saw was — "
   She nodded. "Me …"
   She was grinning now, an open though conspiratorial grin that was very familiar. "When Bertrand Russell was very old, and probably as dotty as I am now, he talked of spreading his interests and attention out to the greater world and away from his own body, so that when that body died he would scarcely notice it, his whole consciousness would be so diluted through the outside world.
   "For him, it was wishful thinking, of course. But not for me. My kernel is out there in the System. Every time I'm there, I transfer a little more of myself. The kernel is growing into a true Erythrina, who is also truly me. When this body dies," she squeezed his hand with hers, "when this body dies, I will still be, and you can still talk to me."
   "Like the Mailman?"
   "Slow like the Mailman. At least till I design faster processors….
   "… So in a way, I am everything you and the Limey were afraid of. You could probably still stop me, Slip." And he sensed that she was awaiting his judgment, the last judgment any mere human would ever be allowed to levy upon her.
   Slip shook his head and smiled at her, thinking of the slow-moving guardian angel that she would become. Every race must arrive at this point in its history, he suddenly realized. A few years or decades in which its future slavery or greatness rests on the goodwill of one or two persons. It could have been the Mailman. Thank God it was Ery instead. And beyond those years or decades… for an instant, Pollack came near to understanding things that had once been obvious. Processors kept getting faster, memories larger. What now took a planet's resources would someday be possessed by everyone. Including himself.
   Beyond those years or decades… were millennia. And Ery.

AFTERWORD by Marvin Minsky

 
   In real life, you often have to deal with things you don't completely understand. You drive a car, not knowing how its engine works. You ride as passenger in someone else's car, not knowing how that driver works. And strangest of all, you sometimes drive yourself to work, not knowing how you work, yourself.
   To me, the import of True Names is that it is about how we cope with things we don't understand. But, how do we ever understand anything in the first place? Almost always, I think, by using analogies in one way or another — to pretend that each alien thing we see resembles something we already know. When an object's internal workings are too strange, complicated, or unknown to deal with directly, we extract whatever parts of its behavior we can comprehend and represent them by familiar symbol — or the names of familiar things which we think do similar things. That way, we make each novelty at least appear to be like something which we know from the worlds of our own pasts. It is a great idea, that use of symbols; it lets our minds transform the strange into the commonplace. It is the same with names.
   Right from the start, True Names shows us many forms of this idea, methods which use symbols, names, and images to make a novel world resemble one where we have been before. Remember the doors to Vinge's castle? Imagine that some architect has invented a new way to go from one place to another: a scheme that serves in some respects the normal functions of a door, but one whose form and mechanism is so entirely outside our past experience that, to see it, we'd never think of it as a door, nor guess what purposes to use it for. No matter: just superimpose, on its exterior, some decoration which reminds one of a door. We could clothe it in rectangular shape, or add to it a waist-high knob, or a push-plate with a sign lettered "EXIT" in red and white, or do whatever else may seem appropriate — and every visitor from Earth will know, without a conscious thought, that pseudo-portal's purpose, and how to make it do its job.
   At first this may seem mere trickery; after all, this new invention, which we decorate to look like a door, is not really a door. It has none of what we normally expect a door to be, to wit: hinged, swinging slab of wood, cut into wall. The inner details are all wrong. Names and symbols, like analogies, are only partial truths; they work by taking many-levelled descriptions of different things and chopping off all of what seem, in the present context, to be their least essential details — that is, the ones which matter least to our intended purposes. But, still, what matters — when it comes to using such a thing — is that whatever symbol or icon, token or sign we choose should remind us of the use we seek which, for that not-quite-door, should represent some way to go from one place to another. Who cares how it works, so long as it works! It does not even matter if that "door" leads to anywhere: in True Names, nothing ever leads anywhere; instead, the protagonists' bodies never move at all, but remain plugged-in to the network while programs change their representations of the simulated realities!
   Ironically, in the world True Names describes, those representations actually do move from place to place — but only because the computer programs which do the work may be sent anywhere within the worldwide network of connections. Still, to the dwellers inside that network, all of this is inessential and imperceptible, since the physical locations of the computers themselves are normally not represented anywhere at all inside the worlds they simulate. It is only in the final acts of the novel, when those partially-simulated beings finally have to protect themselves against their entirely-simulated enemies, that the programs must keep track of where their mind-computers are; then they resort to using ordinary means, like military maps and geographic charts.
   And strangely, this is also the case inside the ordinary brain: it, too, lacks any real sense of where it is. To be sure, most modem, educated people know that thoughts proceed inside the head — but that is something which no brain knows until it's told. In fact, without the help of education, a human brain has no idea that any such things as brains exist. Perhaps we tend to place the seat of thought behind the face, because that's where so many sense-organs are located. And even that impression is somewhat wrong: for example, the brain-centers for vision are far away from the eyes, away in the very back of the head, where no unaided brain would ever expect them to be.
   In any case, the point is that the icons in True Names are not designed to represent the truth — that is, the truth of how the designated object, or program, works; that just is not an icon's job. An icon's purpose is, instead, to represent a way an object or a program can be used. And, since the idea of a use is in the user's mind — and not connected to the thing it represents — the form and figure of the icon must be suited to the symbols that the users have acquired in their own development. That is, it has to be connected to whatever mental processes are already one's most fluent, expressive, tools for expressing intentions. And that's why Roger represents his watcher the way his mind has learned to represent a frog.
