First Bluejay printing: November 1984

In the once upon a time days of the First Age of Magic, the prudent sorcerer regarded his own true name as his most valued possession but also the greatest threat to his continued good health, for — the stories go — once an enemy, even a weak unskilled enemy, learned the sorcerer's true name, then routine and widely known spells could destroy or enslave even the most powerful. As times passed, and we graduated to the Age of Reason and thence to the first and second industrial revolutions, such notions were discredited. Now it seems that the Wheel has turned full circle (even if there never really was a First Age) and we are back to worrying about true names again:

The first hint Mr. Slippery had that his own True Name might be known — and, for that matter, known to the Great Enemy — came with the appearance of two black Lincolns humming up the long dirt driveway that stretched through the dripping pine forest down to Road 29. Roger Pollack was in his garden weeding, had been there nearly the whole morning, enjoying the barely perceptible drizzle and the overcast, and trying to find the initiative to go inside and do work that actually makes money. He looked up the moment the intruders turned, wheels squealing, into his driveway. Thirty seconds passed, and the cars came out of the third-generation forest to pull up beside and behind Pollack's Honda. Four heavy-set men and a hard-looking female piled out, started purposefully across his well-tended cabbage patch, crushing tender young plants with a disregard which told Roger that this was no social call.

Pollack looked wildly around, considered making a break for the woods, but the others had spread out and he was grabbed and frog-marched back to his house. (Fortunately the door had been left unlocked. Roger had the feeling that they might have knocked it down rather than ask him for the key.) He was shoved abruptly into a chair. Two of the heaviest and least collegiate-looking of his visitors stood on either side of him. Pollack's protests — now just being voiced — brought no response. The woman and an older man poked around among his sets. "Hey, I remember this, Al: It's the script for 1965. See?" The woman spoke as she flipped through the holo-scenes that decorated the interior wall.

The older man nodded. "I told you. He's written more popular games than any three men and even more than some agencies. Roger Pollack is something of a genius."

They're novels, damn you, not games! Old irritation flashed unbidden into Roger's mind. Aloud: "Yeah, but most of my fans aren't as persistent as you all."

"Most of your fans don't know that you are a criminal, Mr. Pollack."

"Criminal? I'm no criminal — but I do know my rights. You FBI types must identify yourselves, give me a phone call, and — "

The woman smiled for the first time. It was not a nice smile. She was about thirty-five, hatchet-faced, her hair drawn back in the single braid favored by military types. Even so it could have been a nicer smile. Pollack felt a chill start up his spine. "Perhaps that would be true, if we were the FBI or if you were not the scum you are. But this is a Welfare Department bust, Pollack, and you are suspected — putting it kindly — of interference with the instrumentalities of National and individual survival."

She sounded like something out of one of those asinine scripts he occasionally had to work on for government contracts. Only now there was nothing to laugh about, and the cold between his shoulder-blades spread. Outside the drizzle had become a misty rain sweeping across the Northern California forests. Normally he found that rain a comfort, but now it just added to the gloom. Still, if there was any chance he could wriggle out of this, it would be worth the effort. "Okay, so you have license to hassle innocents, but sooner or later you're going to discover that I am innocent and then you'll find out what hostile media coverage can really be like." And thank God I backed up my files last night. With luck, all they'll find is some out-of-date stock-market schemes. "You're no innocent, Pollack. An honest citizen is content with an ordinary data set like yours there." She pointed across the living room at the forty-by-fifty-centimeter data set. It was the great-grandchild of the old CRTs. With color and twenty-line-per-millimeter resolution, it was the standard of government offices and the more conservative industries. There was a visible layer of dust on Pollack's model. The femcop moved quickly across the living room and poked into the drawers under the picture window. Her maroon business suit revealed a thin and angular figure. "An honest citizen would settle for a standard processor and a few thousand megabytes of fast storage." With some superior intuition she pulled open the center drawer-right under the marijuana plants to reveal at least five hundred cubic centimeters of optical memory, neatly racked and threaded through to the next drawer which held correspondingly powerful CPUs. Even so, it was nothing compared to the gear he had buried under the house.

She drifted out into the kitchen and was back in a moment. The house was a typical airdropped bungalow, small and easy to search. Pollack had spent most of his money on the land and his … hobbies. "And finally," she said, a note of triumph in her voice, "an honest citizen does not need one of these!" She had finally spotted the Other World gate. She waved the electrodes in Pollack's face.

"Look, in spite of what you may want, all this is still legal. In fact, that gadget is scarcely more powerful than an ordinary games interface." That should be a good explanation, considering that he was a novelist.

The older man spoke almost apologetically, "I'm afraid Virginia has a tendency to play cat and mouse, Mr. Pollack. You see, we know that in the Other World you are Mr. Slippery."

"Oh."

There was a long silence. Even "Virginia" kept her mouth shut. This had been, of course, Roger Pollack's great fear. They had discovered Mr. Slippery's True Name and it was Roger Andrew Pollack TIN/SSAN 0959-34-2861, and no amount of evasion, tricky programming, or robot sources could ever again protect him from them. "How did you find out?"

A third cop, a technician type, spoke up. "It wasn't easy. We wanted to get our hands on someone who was really good, not a trivial vandal — what your Coven would call a lesser warlock." The younger man seemed to know the jargon, but you could pick that up just by watching the daily paper. "For the last three months, DoW has been trying to find the identity of someone of the caliber of yourself or Robin Hood, or Erythrina, or the Slimey Limey. We were having no luck at all until we turned the problem around and began watching artists and novelists. We figured at least a fraction of them must be attracted to vandal activities. And they would have the talent to be good at it. Your participation novels are the best in the world." There was genuine admiration in his voice. One meets fans in the oddest places, "so you were one of the first people we looked at. Once we suspected you, it was just a matter of time before we had the evidence."

It was what he had always worried about. A successful warlock cannot afford to be successful in the real world. He had been greedy; he loved both realms too much.

The older cop continued the technician's almost diffident approach. "In any case, Mr. Pollack, I think you realize that if the Federal government wants to concentrate all its resources on the apprehension of a single vandal, we can do it. The vandals' power comes from their numbers rather than their power as individuals."

Pollack repressed a smile. That was a common belief — or faith — within government. He had snooped on enough secret memos to realize that the Feds really believed it, but it was very far from true. He was not nearly as clever as someone like Erythrina. He could only devote fifteen or twenty hours a week to SIG activities. Some of the others must be on welfare, so complete was their presence on the Other Plane. The cops had nailed him simply because he was a relatively easy catch.

"So you have something besides jail planned for me?"

"Mr. Pollack, have you ever heard of the Mailman?"

"You mean on the Other Plane?"

"Certainly. He has had no notoriety in the, uh, real world as yet."

For the moment there was no use lying. They must know that no member of a SIG or coven would ever give his True Name to another member. There was no way he could betray any of the others — he hoped.

"Yeah, he's the weirdest of the werebots."

"Werebots?"

"Were — robots, like werewolves — get it? They don't really mesh with coven imagery. They want some new mythos, and this notion that they are humans who can turn into machines seems to suit them. It's too dry for me. This Mailman, for instance, never uses real time communication. If you want anything from him, you usually have to wait a day or two for each response — just like the old-time hardcopy mail service." "That's the fellow. How impressed are you by him?" "Oh, we've been aware of him for a couple years, but he's so slow that for a long time we thought he was some clown on a simple data set. Lately, though, he's pulled some really — " Pollack stopped short, remembering just who he was gossiping with. " — some really tuppin stunts, eh, Pollack?" The ferncop "Virginia" was back in the conversation. She pulled up one of the roller chairs, till her knees were almost touching his, and stabbed a finger at his chest. "You may not know just how tuppin. You vandals have caused Social Security Records enormous problems, and Robin Hood cut IRS revenues by three percent last year. You and your friends are a greater threat than any foreign enemy. Yet you're nothing compared to this Mailman."

Pollack was rocked back. It must be that he had seen only a small fraction of the Mailman's japes. "You're actually scared of him," he said mildly.

Virginia's face began to take on the color of her suit. Before she could reply, the older cop spoke. "Yes, we are scared. We can scarcely cope with the Robin Hoods and the Mr. Slipperys of the world. Fortunately, most vandals are interested in personal gain or in proving their cleverness. They realize that if they cause too much trouble, they could no doubt be identified. I suspect that tens of thousands of cases of Welfare and Tax fraud are undetected, committed by little people with simple equipment who succeed because they don't steal much — perhaps just their own income tax liability — and don't wish the notoriety which you, uh, warlocks go after. If it weren't for their petty individualism, they would be a greater threat than the nuclear terrorists.

"But the Mailman is different: he appears to be ideologically motivated. He is very knowledgeable, very powerful. Vandalism is not enough for him; he wants control…" The Feds had no idea how long it had been going on, at least a year. It never would have been discovered but for a few departments in the Federal Screw Standards Commission which kept their principal copy records on paper. Discrepancies showed up between those records and the decisions rendered in the name of the FSSC. Inquiries were made; computer records were found at variance with the hardcopy. More inquiries. By luck more than anything else, the investigators discovered that decision modules as well as data were different from the hardcopy backups. For thirty years government had depended on automated central planning, shifting more and more from legal descriptions of decision algorithms to program representations that could work directly with data bases to allocate resources, suggest legislation, outline military strategy.

The take-over had been subtle, and its extent was unknown. That was the horror of it. It was not even clear just what groups within the Nation (or without) were benefitting from the changed interpretations of Federal law and resource allocation. Only the decision modules in the older departments could be directly checked, and some thirty percent of them showed tampering. "…and that percentage scares us as much as anything, Mr. Pollack. It would take a large team of technicians and lawyers months to successfully make just the changes that we have detected."

"What about the military?" Pollack thought of the Finger of God installations and the thousands of missiles pointed at virtually every country on Earth. If Mr. Slippery had ever desired to take over the world, that is what he would have gone for. To hell with pussy-footing around with Social Security checks.

"No. No penetration there. In fact, it was his attempt to infiltrate — " the older cop glanced hesitantly at Virginia, and Pollack realized who was the boss of this operation, " — NSA that revealed the culprit to be the Mailman. Before that it was anonymous, totally without the ego-flaunting we see in big-time vandals. But the military and NSA have their own systems. Impractical though that is, it paid off this time." Pollack nodded. The SIG steered clear of the military, and especially of NSA.

"But if he was able to slide through DoW and Department of Justice defenses so easy, you really don't know how much a matter of luck it was that he didn't also succeed with his first try on NSA …. I think I understand now. You need help. You hope to get some member of the Coven to work on this from the inside."

"It's not a hope, Pollack," said Virginia. "It's a certainty. Forget about going to jail. Oh, we could put you away forever on the basis of some of Mr. Slippery's pranks. But even if we don't do that, we can take away your license to operate. You know what that means."

It was not a question, but Pollack knew the answer nevertheless: ninety-eight percent of the jobs in modem society involved some use of a data set. Without a license, he was virtually unemployable — and that left Welfare, the prospect of sitting in some urbapt counting flowers on the wall. Virginia must have seen the defeat in his eyes. "Frankly, I am not as confident as Ray that you are all that sharp. But you are the best we could catch. NSA thinks we have a chance of finding the Mailman's true identity ff we can get an agent into your coven. We want you to continue to attend coven meetings, but now your chief goal is not mischief but the gathering of information about the Mailman. You are to recruit any help you can without revealing that you are working for the government — you might even make up the story that you suspect the Mailman of being a government plot. (I'm sure you see he has some of the characteristics of a Federal agent working off a conventional data set.) Above all, you are to remain alert to contact from us, and give us your instant cooperation in anything we require of you. Is all this perfectly clear, Mr. Pollack?"

He found it difficult to meet her gaze. He had never really been exposed to extortion before. There was something … dehumanizing about being used so. "Yeah," he finally said.

"Good." She stood up, and so did the others. "If you behave, this is the last time you'll see us in person."

Pollack stood too. "And afterward, if you're… satisfied with my performance?" Virginia grinned, and he knew he wasn't going to like her answer. "Afterward, we can come back to considering your crimes. If you do a good job, I would have no objection to your retaining a standard data set, maybe some of your interactive graphics. But I'll tell you, ff it weren't for the Mailman, nabbing Mr. Slippery would make my month. There is no way I'd risk your continuing to abuse the System."

Three minutes later, their sinister black Lincolns were halfway down the drive, disappearing into the pines. Pollack stood in the drizzle watching till long after their sound had faded to nothing. He was barely aware of the cold wet across his shoulders and down his back. He looked up suddenly, feeling the rain in his face, wondering if the Feds were so clever that they had taken the day into account: the military's recon satellites could no doubt monitor their cars, but the civilian satellites the SIG had access to could not penetrate these clouds. Even if some other member of the SIG did know Mr. Slippery's True Name, they would not know that the Feds had paid him a visit.

Pollack looked across the yard at his garden. What a difference an hour can make.

By late afternoon, the overcast was gone. Sunlight glinted off millions of waterdrop jewels in the trees. Pollack waited till the sun was behind the tree line, till all that was left of its passage was a gold band across the taller trees to the east of his bungalow. Then he sat down before his equipment and prepared to ascend to the Other Plane. What he was undertaking was trickier than anything he had tried before, and he wanted to take as much time as the Feds would tolerate. A week of thought and research would have suited him more, but Virginia and her pals were clearly too impatient for that.

He powered up his processors, settled back in his favorite chair, and carefully attached the Portal's five sucker electrodes to his scalp. For long minutes nothing happened: a certain amount of self-denial — or at least self-hypnosis — was necessary to make the ascent. Some experts recommended drugs or sensory isolation to heighten the user's sensitivity to the faint, ambiguous signals that could be read from the Portal. Pollack, who was certainly more experienced than any of the pop experts, had found that he could make it simply by staring out into the trees and listening to the wind-surf that swept through their upper branches.

And just as a daydreamer forgets his actual surroundings and sees other realities, so Pollack drifted, detached, his subconscious interpreting the status of the West Coast communication and data services as a vague thicket for his conscious mind to inspect, interrogate for the safest path to an intermediate haven. Like most exurb data-commuters, Pollack rented the standard optical links: Bell, Boeing, Nippon Electric. Those, together with the local West Coast data companies, gave him more than enough paths to proceed with little chance of detection to any accepting processor on Earth. In minutes, he had traced through three changes of carrier and found a place to do his intermediate computing. The comsats rented processor time almost as cheaply as ground stations, and an automatic payment transaction (through several dummy accounts set up over the last several years) gave him sole control of a large data space within milliseconds of his request. The whole process was almost at a subconscious level — the proper functioning of numerous routines he and others had devised over the last four years. Mr. Slippery (the other name was avoided now, even in his thoughts) had achieved the fringes of the Other Plane. He took a quick peek through the eyes of a low-resolution weather satellite, saw the North American continent spread out below, the terminator sweeping through the West, most of the plains clouded over. One never knew when some apparently irrelevant information might help — and though it could all be done automatically through subconscious access, Mr. Slippery had always been a romantic about spaceflight.

He rested for a few moments, checking that his indirect communication links were working and that the encryption routines appeared healthy, untampered with. (Like most folks, honest citizens or warlocks, he had no trust for the government standard encryption routines, but preferred the schemes that had leaked out of academia — over NSA's petulant objections — during the last fifteen years.) Protected now against traceback, Mr. Slippery set out for the Coven itself. He quickly picked up the trail, but this was never an easy trip, for the SIG members had no interest in being bothered by the unskilled.

In particular, the traveler must be able to take advantage of subtle sensory indications, and see in them the environment originally imagined by the SIG. The correct path had the aspect of a narrow row of stones cutting through a gray-greenish swamp. The air was cold but very moist. Weird, towering plants dripped audibly onto the faintly iridescent water and the broad lilies. The subconscious knew what the stones represented, handled the chaining of routines from one information net to another, but it was the conscious mind of the skilled traveler that must make the decisions that could lead to the gates of the Coven, or to the symbolic "death" of a dump back to the real world. The basic game was a distant relative of the ancient Adventure that had been played on computer systems for more than forty years, and a nearer relative of the participation novels that are still widely sold. There were two great differences, though. This game was more serious, and was played at a level of complexity impossible without the use of the EEG input/output that the warlocks and the popular data bases called Portals.

There was much misinformation and misunderstanding about the Portals. Oh, responsible data bases like the LA Times and the CBS News made it clear that there was nothing supernatural about them or about the Other Plane, that the magical jargon was at best a romantic convenience and at worst obscurantism. But even so, their articles often missed the point and were both too conservative and too extravagant. You might think that to convey the full sense imagery of the swamp, some immense bandwidth would be necessary. In fact, that was not so (and ff it were, the Feds would have quickly been able to spot warlock and werebot operations). A typical Portal link was around fifty thousand baud, far narrower than even a flat video channel. Mr. Slippery could feel the damp seeping through his leather boots, could feel the sweat starting on his skin even in the cold air, but this was the response of Mr. Slippery's imagination and subconscious to the cues that were actually being presented through the Portal's electrodes. The interpretation could not be arbitrary or he would be dumped back to reality and would never find the Coven; to the traveler on the Other Plane, the detail was there as long as the cues were there. And there is nothing new about this situation. Even a poor writer if he has a sympathetic reader and an engaging plot — can evoke complete internal imagery with a few dozen words of description. The difference now is that the imagery has interactive significance, just as sensations in the real world do. Ultimately, the magic jargon was perhaps the closest fit in the vocabulary of millenium Man.

The stones were spaced more widely now, and it took all Mr. Slippery's skill to avoid falling into the noisome waters that surrounded him. Fortunately, after another hundred meters or so, the trail rose out of the water, and he was walking on shallow mud. The trees and brush grew in close around him, and large spider webs glistened across the trail and between some of the trees along the side.

Like a yo-yo from some branch high above him, a red-banded spider the size of a man's fist descended into the space right before the traveler's face. "Beware, beware," the tiny voice issued from dripping mandibles. "Beware, beware," the words were repeated, and the creature swung back and forth, nearer and farther from Mr. Slippery's face. He looked carefully at the spider's banded abdomen. There were many species of deathspider here, and each required a different response if a traveler was to survive. Finally he raised the back of his hand and held it level so that the spider could crawl onto it. The creature raced up the damp fabric of his jacket to the open neck. There it whispered something very quietly.

Mr. Slippery listened, then grabbed the animal before it could repeat the message and threw it to the left, at the same time racing off into the tangle of webs and branches on the other side of the trail. Something heavy and wet slapped into the space where he had been, but he was already gone-racing at top speed up the incline that suddenly appeared before him.

He stopped when he reached the crest of the hill. Beyond it, he could see the solemn, massive fortress that was the Coven's haven. It was not more than five hundred meters away, illuminated as the swamp had been by a vague and indistinct light that came only partly from the sky. The trail leading down to it was much more open than the swamp had been, but the traveler proceeded as slowly as before: the sprites the warlocks set to keep eternal guard here had the nasty-though preprogrammed habit of changing the rules in new and deadly ways.

The trail descended, then began a rocky, winding climb toward the stone and iron gates of the castle. The ground was drier here, the vegetation sparse. Leathery snapping of wings sounded above him, but Mr. Slippery knew better than to look up. Thirty meters from the moat, the heat became more than uncomfortable. He could hear the lava popping and hissing, could see occasional dollops of fire splatter up from the liquid to scorch what vegetation still lived. A pair of glowing eyes set in a coal-black head rose briefly from the moat. A second later, the rest of the creature came surging into view, cascading sparks and lava down upon the traveler. Mr. Slippery raised his hand just so, and the lethal spray separated over his head to land harmlessly on either side of him. He watched with apparent calm as the creature descended ancient stone steps to confront him.

Alan — that was the elemental's favorite name — peered nearsightedly, his head weaving faintly from side to side as he tried to recognize the traveler. "Ah, I do believe we are honored with the presence of Mr. Slippery, is it not so?" he finally said. He smiled, an open grin revealing the glowing interior of his mouth. His breath did not show flame but did have the penetrating heat of an open kiln. He rubbed his clawed hands against his asbestos T-shirt as though anxious to be proved wrong. Away from his magma moat, the dead black of his flesh lightened, trying to contain his body heat. Now he looked almost reptilian.

"Indeed it is. And come to bring my favorite little gifts." Mr. Slippery threw a leaden slug into the air and watched the elemental grab it with his mouth, his eyes slitted with pleasure-melt-in-your-mouth pleasure. They traded conversation, spells, and counterspells for several minutes. Alan's principal job was to determine that the visitor was a known member of the Coven, and he ordinarily did this with little tests of skill (the magma bath he had tried to give Mr. Slippery) and by asking the visitor questions about previous activities within the castle. Alan was a personality simulator, of course. Mr. Slippery was sure that there had never been a living operator behind that toothless, glowing smile. But he was certainly one of the best, probably the product of many hundreds of blocks of psylisp programming, and certainly superior to the little "companionship" programs you can buy nowadays, which generally become repetitive after a few hours of conversation, which don't grow, and which are unable to counter weird responses. Alan had been with the Coven and the castle since before Mr. Slippery had become a member, and no one would admit to his creation (though Wiley J. was suspected). He hadn't even had a name until this year, when Erythrina had given him that asbestos Alan Turing T-shirt.

Mr. Slippery played the game with good humor, but care. To "die" at the hands of Alan would be a painful experience that would probably wipe a lot of unbacked memory he could ill afford to lose. Such death had claimed many petitioners at this gate, folk who would not soon be seen on this plane again.
