"I go first," said Virgil quietly, "with the Sceptre. Hyacinth follows with her .44. Bud follows her with the heavy gloves, then Sarah and Casimir with the backpacks, and Fred in the rear with his sixteen-gauge. No noise."

After one or two turns of the stair we had to switch on our headlamps. The trip down was long and tense, and we seemed to make a hellacious racket on the echoing metal treads. I kept my beam on the blazing white-gold beacon of Virgil's hair and listened to the breathing and the footsteps behind me. The air had a harsh damp smell that told me I was sucking in billions of microbes of all descriptions with each breath. Toward the bottom we slipped on our gas masks, and I found I was breathing much faster than I needed to.

The rats were waiting a full fifty feet above the bottom. One had his mouth clamped over Virgil's lower leg before he had switched on the Sceptre of Cosmic Force. The flashing drove away the rest of the rats, who tumbled angrily down the stair on top of one another, but the first beast merely clamped down harder and hung on, too spazzed out to move. Fortunately, Hyacinth did not try to shoot it on the spot. I slipped past, flexed my big elbow-length padded gloves, and did battle with the rat. The rodent teeth had not penetrated the soccer shinguards Virgil wore beneath his waders, so I took my time, relaxing and squatting down to look into the animal's glowering white-rimmed eye. His bared chisel teeth, a few inches long and an inch wide, flickered purple-yellow with each flash of the strobe. Having sliced through Virgil's waders to expose the colorful plastic shinguard, the rat now tried to gnaw its way through the obstacle without letting go. I did not have the strength to pull its mouth open.

"A German shepherd can exert hundreds of pounds of jaw force," said Fred Fine, standing above and peering over Casimir's shoulder with scientific coolness.

The rat was not impressed by any of this.

"Let's go for a clean kill," suggested its victim with a trace of strain, "and then we'll have our sample."

I bashed in the back of its head with an oaken leg I had foresightedly unscrewed from my kitchen table for the occasion. The rat just barely fit into a large heavy-duty leaf bag; Virgil twist-tied it shut and we left it there.

And so into the tunnels. The sewers were unusually fluid that night as thousands of cubic feet of beer made its traditional way through the digestive tracks of the degenerates upstairs and into the sanitary system. Hence we stuck to the catwalks along the sides of the larger tunnels— as did the rats. The Sceptre was hard on our eyes, so Virgil waited until they were perilously close before switching it on and driving them in squalling bunches into the stream below. We did not have to use the guns, though Fred Fine insisted on shooting his flash gun at a rat to see how they liked it. Not at all, as it happened, and Fred Fine pronounced it "very interesting."

Casimir said, "Where did my radioactive source fall to? Are we going anywhere near there?"

"Good point," said Fred Fine. "Let's steer clear of that. Don't want blasted 'nads."

"I know where it went, but it's not there now," said Virgil. "The rats ate everything. Some rat obviously got a free surprise in with his paraffin, but I don't know where he ended up.' Fred Fine began to point out landmarks: where he had left the corpse of the Microwave Lizard, long since eaten by you know what; where Steven Wilson had experienced his last and biggest surprise; the tunnel that led to the Sepulchre of Keldor. His voice alternated between the pseudo-scientific dynamo hum of Fred Fine and the guttural baritone of the war hero. We had heard this stuff from him for a couple of weeks now, but down in the tunnels it really started to perturb us. Most people, on listening to a string of nonsense, will tend to doubt their own sanity before they realize that the person who is jabbering at them is really the one with the damaged brain. That night, tramping through offal, attacking giant rats with a strobe light and listening to the bizarre memoirs of Klystron, most of us were independently wondering whether or not we were crazy. So when we asked Fred Fine for explanations, it was not because we wanted to hear more Klystron stories (as he assumed); it was because we wanted to get an idea of what other people were thinking. We were quickly able to realize that the world was indeed okay, that Fred Fine was bonkers and we were fine.

Hundreds of cracked and gnawed bones littered one intersection, and Virgil identified it as where he had discovered the useful properties of the Sceptre. This area was high and dry, as these things went, and many rats lurked about. Virgil switched the Sceptre on for good, forcing them back to the edge of the dark, where they chattered and flashed their red eyes. Hyacinth stuffed wads of cotton in her ears, apparently in case of a shootout.

"Let's set up the 'scope," Virgil suggested. Casimir swung off his pack and withdrew a heavily padded box, from which he took a small portable oscilloscope. This device had a tiny TV screen which would display sound patterns picked up by a shotgun microphone which was also in the pack. As the 'scope warmed up, Casimir plugged the microphone cord into a socket on its front. A thin luminous green line traced across the middle of the screen.

Virgil aimed the mike down the main passageway and turned it on. The line on the screen split into a chaotic tangle of dim green static. Casimir played with various knobs, and quickly the wild flailing of the signal was compressed into a pattern of random vibes scrambling across the screen. "White noise," said Fred Fine. "Static to you laymen."

"Keep an eye on it," said Virgil, and pointed the mike down the smaller side tunnel. The white noise was abruptly replaced by nearly vertical lines marching across the screen. Casimir compressed the signal down again, and we saw that it was nothing more than a single stationary sine wave, slightly unruly but basically stable.

"Very interesting," said Fred Fine.

"What's going on?" Sarah asked.

"This is a continuous ultrasonic tone," said Virgil. "It's like an unceasing dog whistle. It comes from some artificial source down that tunnel. You see, when I point the mike in most directions we get white noise, which is normal. But this is a loud sound at a single pitch. To the rats it would sound like a drawn-out note on an organ. That explains why they cluster in this particular area; it's music to their ears, though it's very simple music. In fact, it's monotonous."

"How did you know to look for this?" asked Sarah.

Virgil shrugged. "It was plausible that an installation as modern and carefully guarded as the one I saw would have some kind of ultrasonic alarm system. It's pretty standard."

"Very interesting," said Fred Fine.

"It's like sonar. Anything that disturbs the echo, within a certain range, sets off the alarm. Here's the question: why don't the rats set it off?"

"Some kind of barrier keeps them away," said Casimir.

"I agree. But I didn't see any barrier. When I was here before, they could run right up to the door— they had to be fought off with machine guns. They must have put up a barrier since I was last down here. What that means to us is this: we can go as far as the barrier, whatever it may be, without any fear of setting off the alarm system."

We moved down the tunnel in a flying wedge, making use of table leg, Sceptre and sword as necessary. Soon we arrived at the barrier, which turned out to be insubstantial but difficult to miss: a frame of angle-irons welded together along the walls and ceiling, hung with dozens of small, brilliant spotlights. At this point, any rat would find itself bathed in blinding light and turn back in terror and pain. Beyond this wall of light there was only a single line of footprints— human— in the bat guano. "Someone's been changing the light bulbs," concluded Sarah.

The fifty feet of corridor preceding the light-wall were littered almost knee-deep in glittering scraps of tinfoil and other bright objects, including the remains of Fred Fine's radio. "This is their hangout," said Hyacinth. "They must like the music."

"They want to make a nice, juicy meal out of whoever changes those light bulbs," suggested Fred Fine.

Sarah's pack contained a tripod and a pair of fine binoculars. Once we had set these up in the middle of the tunnel we could see the heavy doors, TV cameras, lights and so on at the tunnel's end. As we took turns looking and speculating, Virgil set up a Geiger counter from Sarah's pack.

"Normally a Geiger counter would just pick up a lot of background and cosmic radiation and anything meaningful would be drowned out. But we're so well shielded in these tunnels that the only thing getting to us should be a few very powerful cosmic rays, and neutrinos, which this won't pick up anyway." The Geiger counter began to click, perhaps once every four seconds.

Sarah had the best eyes; she sat crosslegged on the layers of foil and gazed into the binoculars. "In a few minutes a hazardous waste pickup is scheduled for the loading dock upstairs," said Virgil, checking his watch. "My theory is that, in addition to taking hazardous wastes out of the Plex, those trucks have been bringing something even more hazardous into the Plex, and down into this tunnel."

We waited.

"Okay," said Sarah, "Elevator door opening on the right." We all heard it.

"Long metal cylinder thingie on a cart. Now the end of the tunnel is opening up— big doors, like jaws. Now some guys in yellow are rolling the cylinder into a large room back there." The Geiger counter shouted. I looked at Casimir.

"Skip your next chest X-ray," he said. "If this place is what it looks like, it's just Iodine-131. Half-life of eight days. It'll end up in your thyroid, which you don't really need anyway."

"I'm pretty fond of my thyroid," said Hyacinth. "It made me big and strong."

"Doors closing," said Sarah over the chatter of us and the Geiger counter. "Elevator's gone. All doors closed now." "Well! Congratulations, Virgil," said Fred Fine, shaking his hand. "You've discovered the only permanent high-level radioactive waste disposal facility in the United States."

Most of us didn't have anything to say about it. We mainly wanted to get back home.

"Fascinating, brilliant," continued Fred Fine, as we headed back. "In today's competitive higher education market, there has to be some way for universities to support themselves. What better way than to enter lucrative high-technology sectors?"

"Don't have to grovel for the alumni anymore," said Sarah. "You really think universities should be garbage dumps for the worst by-products of civilization?" asked Hyacinth.

"It's not such a bad idea, in a way," said Casimir. "Better the universities than anyone else. Oxford, Heidelberg, Paris, all those places have lasted for centuries longer than any government. Only the Church has lasted longer, and the Vatican doesn't need the money."

We paused for a rest in the spiral staircase, near our rat body. Casimir, Fred Fine and Virgil went back down to the bottom for an experiment. Virgil had brought an ultrasonic tone generator with him, and they used it to prove— very conclusively— that the rats loved the ultrasound as much as they hated the strobe. They ran back upstairs, Sceptre flashing, and I slung the rat over my shoulder and we all proceeded up the stairs as fast as our lungs would allow.

The dissection of the rat was most informal. We did it in the sink of Professor Sharon's old lab, amid the pieces of the railgun. Fred Fine laid into the thorax with a kitchen knife and a single-edged razor. We were quick and crude; only Casimir had seen the inside of a rat before. The skin peeled back easily along with thick pink layers of fat, and we looked at the intestines that could digest such amazing meals. Casimir scrounged a pair of heavy tin snips and used them to cut the breastbone in half so we could get under the ribcage. I shoved my hands between the halves of the breastbone and pulled as hard as I could, and finally with a crack and a spray of blood one side snapped open like a stubborn cabinet door and we looked at the lungs and vital organs. The heart was not immediately visible.

"Maybe it's hidden under this organ here," suggested Fred Fine, pointing to something between the lungs.

"That's not an organ," said Casimir. "It's an intersection of several major vessels."

"So where's the heart?" asked Hyacinth, just beginning to get interested.

"Those major vessels are the ones that ought to go into, and come out of, the heart," said Casimir uncertainly. He reached down and slid his hand under the bundle of vessels, and pulling it up and aside, revealed— nothing.

"Holy Mother of God," he whispered. "This animal doesn't have a heart."

Our own thumped violently. For a long time we were frozen, disturbed beyond reason; then a piercing beep emanated from Fred Fine and we jumped and gasped angrily.

Unconcerned, he pressed a button on his digital calculator/watch, halting the beep. "Sorry. That's my watch alarm."

We looked at him; he looked at his watch, We were all sweating.

"I set it to go off like that at midnight, the beginning of April first, every year. It's sort of a warning, so that this one remembers, hey, April Fools' Day, anything could happen now."

While we sewer-slogged, E13S held a giant party in honor of Big Wheel. It was conceived as your basic formless beer blowout, but the ever-spunky Airheads had insisted upon a theme: Great Partiers of the Past. The major styles in evidence were Disco, Sixties, Fifties and Toga. A team of sturdy Terrorists had lugged Dex Fresser's stereo up to the social lounge, which was the center of Disco activity. A darkened room down the hail featured a Sixties party, at which participants roughed up their perms, wore T-shirts, smoked more dope than usual and said "groovy" at the drop of a hat. The study lounge was Fifties headquarters, and was identical to all the other Fifties parties which had been held since about 1963 by people who didn't know anything about the Fifties. The Toga people were forced to adopt a wandering, nomadic partying existence; they had no authentic toga music to boogie to, though someone did experiment by playing an electronic version of the "1812 Overture" at full blast. Mostly these people just stood sheepishly in the hallways, draped in their designer bedsheets, clutching cups of beer and yelling "toga!" from time to time.

The Disco lounge was filled with women in lollipop plastic dresses and thick metallic lipstick under ski masks, and heavily scented young men in pastel three-piecers and shiny hardware-laden shoes. The smell was deafening, and when the doors were open, excess music spilled out and filled nearby rooms to their corners. These partiers were a generation whose youth had been stolen. They had prepared all through their adolescence for the day when they could go to college and attend real discos, adult discos where they had alcohol and sex partners you could take home with no pay-rental hassles. Their hopes had been dashed in the early eighties when Disco had flamed out somewhere over New Jersey, like a famous dirigible. But the nostalgic air here made them feel young again. Dex Fresser even showed up in a white three-piecer and took several opportunities to boogie right down to the ground with shapely females in clingy synthetic wraps.

On the windowsill, the Go Big Red Fan, held in place with bricks, spun and glowed in its self-made halo of black light. Overhead, a mirrored ball cast revolving dots of light on the walls, and more stoned or imaginative dancers could imagine that they were actually standing inside a giant Big Wheel. Whoooo! The picture windows were covered with newspaper, as the panes had long since been smashed and the curtains long since burned.

After Dex Fresser had consumed sixteen hits of acid (his supplier had never really grasped the idea of powers of two), five bongloads of hashish rolled in mescaline, a square of peyote Jell-O, a lude, four tracks, a small handful of street-legal caffeine pep pills, twelve tablespoons of cough syrup, half a can of generic light wine and a pack of Gaulois cigarettes, he began to toy with a strobe light that was being used to establish the Disco atmosphere. He turned it up faster and faster until the lounge was wracked with delighted freakedout screams and the dancers had begun to hop randomly and smash into one another, as though they had been time-warped into Punk. Meanwhile, what passed for Dex's mind wandered over to the Go Big Red Fan, and though the time-warp effect was really blowing his tubes, he thought the fan might be slowing down; continuing to turn up the strobe, he was able to make the Little Wheel stop revolving altogether— either that, or time itself had come to a halt! Dex spazzed out to the max. All became quiet as the propulsion reactors of a passing Sirian space cruiser damped out his stereo (the DJ had turned down the volume), and all heard Dex announce that at midnight Big Wheel would say something very important to him. He relaxed, the music was cranked back up, the strobe light hurled out a nearby window and the Fan began to rotate again.

Midnight could hardly come soon enough. The partiers packed into the social lounge, sitting in rows facing the window. Dex Fresser stood before the shrouded window with his back to the crowd, and priests stood ready to tear the papers away. A few minutes before midnight, the DJ put on "Stairway to Heaven," timed so that the high-energy sonic blast section would begin at 12:00 sharp.

The newspapers ripped apart, the red-white-and-blue power beams of Big Wheel exploded into the room, and the heavy beat of the rock and roll made their thoraxes boom like empty kegs. But Dex Fresser was impressively still. He stared into the naked face of the Big Wheel for fifteen minutes before he moved a muscle. Then he relayed the message to the huddled students. Speaking through a mike hooked to his stereo, he sounded loud and quadraphonic. "Tonight the Big Wheel has plans for us, man. We're going to have a fucking war." The Terrorists cheered and whooped and the Airheads oohed and aahed. "The outside people, who are all hearing-impaired to the voice of Big Wheel and Roy G Biv and our other leaders, will come tomorrow to the Plex with guns to kill us. They want to put short-range tactical nuclear weapons on the roof of D Tower in order to threaten Big Wheel and make him do as they wish.

"We have friends, though, like Astarte, the Goddess, who is the sister of Big Wheel and who is going to like help us out and stuff. The Terrorists and the SUB will cooperate just like Big Wheel and Astarte do. Also, the B-men are our friends too.

"We've got shitloads of really powerful enemies, says Big Wheel. Like the Administration and the Temple of Unlimited Godhead and a bunch of nerds and some other people. We have to kill all of them.

"This is going to take cooperation and we have to have perfect loyalty from everyone. See, even if you think you have friends among our enemies, you're wrong, because Big Wheel decides who our friends are, and if he says they're your enemies, they're your enemies, just like that. Everything's very simple with Big Wheel, that's how you can be sure he's telling the truth. So we've got to join together now and there can't be any secrets and we can't cover up for our enemies or have mercy for them."

Mari Meegan, sitting in the front row, legs tucked demurely to the side, listened intensely, eyes slitted and lips parted as she thought about how this applied to her.

At this point a few people came to their senses and made a run for it. One of these, a none-too-bright advisee of mine who had been going along for the good times, realized that these people were nuts, sprinted to the nearest fire stair, and escaped unharmed, later to tell me this story. What happened after his exit is vague; apparently, Yllas Freedperson, High Priestess of Astarte, showed up, and the leaders of the SUB and of the Terrorists did a lot of planning and organizing in those next few hours.

By contrast, Bert Nix celebrated the evening by incinerating himself in a storage room on C22W. He had been using it as a hideout for some time, and had gotten along well with the students, except for one problem: Bert Nix's obsession with collecting garbage. It was partly a practical habit, as he got most of his food and clothing from the trash. Far beyond that, however, he could not bring himself to throw out anything, and so in his little rooms scattered around the Plex the garbage was packed in to the ceiling, leaving only a little aisle to the door. Out of gratitude to his protectors, Bert Nix stuffed oily rags under the doors to seal the odor in.

This sufficed until the evening of March 31, when he happened to open the door while a fastidious student from Saskatoon was walking by. She watched as half a dozen cockroaches over three inches long lumbered out between the derelict's bare feet and approached her, waving their antennae affably. No Airhead, she stomped them to splinters and called Security on the nearest telephone. Between then and the time they arrived five hours later, however, the fire started. It could have been spontaneous combustion, it could have been the heating system, or a suicidal whim or wayward cigarette from Bert Nix. In any event, the room became a tightly sealed furnace, and when the flames had died, all that remained were a charred corpse in the aisle and drifts of cockroach bodies piled up in front of the door.

At the northern corner of the Plex's east wall, north of the Mall loading docks, the docks for student use, the mail, Cafeteria, general supply, Burrows and wide-load docks was the Refuse Area. Six loading docks opened on an enormous room with six giant trash compactors and six great steel chutes which expelled tons of garbage from their foul, stained sphincters every few minutes. When there wasn't a strike on, the compactors would grind away around the clock and a great truck would be at one dock or another at any given time, bringing back an empty container and hauling off a full one.

North of the Refuse Area, in the very corner of the Flex, was the Hazardous Waste Area with its steel doors and explosion-proof walls. When scientists produced any waste that was remotely hazardous, they would seal it into an orange container, mark down its contents and take it to the Refuse Area, where they could deposit it in a chute that led into the HWA. If the container was too large for this, they could simply leave it on a dolly by the door, and the specially trained B-men would then wheel it through when it was time for a pickup. When the Hazardous Waste truck arrived, three times a day, all the containers were then loaded into its armor-plated back and hauled away. This was usually done in the dead of night, to lessen the danger of traffic accidents. So extraordinary was this disposal system that American Megaversity had won awards from environmental groups and acclaim from scientists.

At 4:30 on the morning of April 1, when I should have been drinking or sleeping, I was sitting in my suite staring at the telephone. Virgil Gabrielsen, even more ambitious, was sitting by the door to the HWA in a huge orange crate about the shape of a telephone booth. "HANDLE WITH EXTREME CARE," its label read, "CONTAINS UNIVERSAL SOLVENT. DO NOT PUT ON SIDE OR EXPLOSION WILL RESULT." The same concepts were repeated by means of ideograms which we had hastily painted on the sides, showing a Crotobaltislavonian stick figure being blown to bits after putting the crate on its side. Instructions to telephone Dr. Redfield, and giving my telephone number, were added in several places.

"The nuke waste has to be coming in through the HWA," Virgil had insisted, as he and I and the disemboweled rat relaxed in Sharon's lab. "I counted my steps down there in the tunnels. As far as I can tell, that elevator shaft should go right up into the northeast corner of the building. The HWA is locked and alarmed within an inch of its life, but I know how to get inside."

At quarter to five, the enormous Magrov and half a dozen other Crotobaltislavonians entered the Refuse Area. As Virgil watched through strategically placed peepholes, they began with some unusual procedures. First they opened the southernmost of the six metal doors to the Access Lot. Shortly after, an old van backed up to this dock and threw open its rear doors. Two men jumped out into the Refuse Area in protective clothing, gas masks dangling on their chests, and exchanged hearty Scythian greetings with the B-men. Much equipment was now hauled out of the van, including a long metal cylinder— an exact replica of a nuclear waste container— and a huge tripod-mounted machine gun. Then came numerous small machine guns, what appeared to be electronic equipment and crates of supplies. These were piled on a cart and wheeled over to Virgil's position.

Virgil had realized by now that this was not a business-as-usual day. At least the situation appealed to his sense of humor. The fake nuke waste cylinder opened like a casket and the two gas-masked men climbed in and lay one atop the other. The others handed them weapons and closed the lid. This cylinder was also placed next to Virgil. In the meantime, B-men bolted the big gun's tripod directly into the concrete floor at the loading dock, apparently having already drilled the holes in preparation. The weapon was aimed into the Access Lot, and loaded and checked over with an experienced air unusual among janitors.

Virgil's crate was the source of a long and emotional discussion in Scythian. Occasionally Magrov or one of the others would shout something about telefon while pounding on the crate with his index finger.

"Hoy!" shouted a B-man back at the machine gun. Virgil saw a glint of headlights outside. It was 4:59. A hellacious roar ensued as the determined janitors sprayed several thousand rounds per minute out the door. Magrov cut off debate by seizing Virgil's crate and wheeling it into the HWA.

The gunfire was over before Virgil was all the way through the door. Once the crate was stopped and he was able to get his bearings again, he could see that he was in a somewhat smaller room with a segmented metal door in the outside wall and a large red rectangle painted in the middle of the floor. A dozen or so bright orange waste containers had been slid through the chute and were waiting on a counter to be hauled away.

My phone rang at 5:01.

"Profyessor Rettfeelt? Sorry, getting you up early in mornink. Magrov here. You put humongous waste container by HWA, correct?"

"Yes, that's correct. Universal Solvent. Very dangerous."

"Ees too tall for goink inside of vaste truck. Ve must put on her side."

"No! That's dangerous. You will be blown to little bits."

"Then what to do with it?"

"I'll have to put it in a different container. You must leave it in the HWA overnight. I will come to the Refuse Area tomorrow night, at the time of the next pickup, and get the crate and take it away." "Good." Magrov hung up.

Back in the HWA, Magrov checked his watch, then turned and shouted at a swiveling TV camera on the wall. "Ha! Those profyessors! Say! Where is truck? Very late today."

"Roger, team leader, we read four minutes late," said an Anglo voice over a loudspeaker. "Maybe some trouble with those strikers. Hey! Let's cut the idle chitchat."

Finally the great steel door rolled open. Through one of his peepholes, Virgil could see a hazardous waste truck backing into the brilliantly lit, fenced-in area outside. He could also see a pair of half-inch bullet holes through the outside rear-view mirror. The tiny black-and-white monitors, he knew, would never pick up this detail. When it had come to rest, the B-men unlocked the back with Magrov's keys and pulled open armored doors to reveal a stainless steel cylinder on a cart. This they rolled into the HWA, placing it in the middle of the red rectangle on the floor.

Other B-men set about hauling the small orange containers into the back of the truck and strapping them down. Magrov removed guns from a locked cabinet and distributed them to himself and two others. There three took up positions in the red area around the cylinder. "Hokay, ready for little ride," said Magrov. "Roger, team leader. Stand by." A deep hum and vibration commenced. The men and the cylinder began to sink, and Virgil could see that the red rectangle was actually an elevator platform. Within seconds only a black hole remained.

In five minutes the platform returned, with the B-men but without the cylinder. Displaying frank contempt for safety regulations, the B-men began to smoke profusely.

The intercom crackled alive. "Crotobaltislavonia aiwa!" came the exhilarated shout.

"Crotobaltislavonia aiwa!" howled the B-men, leaping to their feet. There was much whoopee-making and cigarette-throwing, and then they opened the door to the Refuse Area and carried in crate after crate of supplies and put them on the elevator platform. The platform, laden with Crotobaltislavonians, guns and food, sank into the earth once again, then returned in a few minutes carrying nine bleeding bodies in yellow radiation suits.

Virgil had been expecting TV cameras. If they had them down in the tunnels, they must have them upstairs in the HWA. So after a few minutes, when Virgil was sure that the B-men were down there for the long haul, he opened a small panel in the side of his crate and stuck out a long iron rod with a magnesium tip. The important thing about the magnesium rod was that Virgil had just set it on fire, and when magnesium burns, it makes an intolerably brilliant light.
