Around 4:00 in the morning, to Sarah's satisfaction, Hyacinth passed out. Sarah allowed herself to do likewise for a while. Then she dragged Hyacinth out onto the rug, dried her and hoisted her into bed. They slept until 4:32 in the afternoon. Sleet was ticking against the window. Hyacinth cut a slit in the window screen and they fed the hose outside and siphoned all the bathwater out of the pool and down the side of the Plex. They ate all of Sarah's mother's banana bread, thirty-two Chips Ahoys, three bowls of Captain Crunch, a pint of strawberry ice cream and drank a great deal of water. They then gave each other backrubs and went to sleep again.

"Keeping my .38 clean is a pain in the ass," said Sarah at one point. "It picks up a lot of crud in my backpack pocket." "That's one reason to carry a single-action," said Hyacinth. "Less to go wrong if it's dirty."

A long time later, Sarah added, "This is pretty macho. Talking about our guns."

"I suppose it's true that they're macho. But they are also guns. In fact, they're primarily guns."

"True."

They also discussed killing people, which had become an important subject with them recently.

"Sometimes there isn't any choice," Sarah said to Hyacinth, as Hyacinth cried calmly into her shoulder. "You know, Constantine punished rapists by pouring molten lead down their throats. That was a premeditated, organized punishment. What you did was on the spur of the moment."

"Yeah. Putting on protective clothes, loading my gun, tracking them down and blowing one away was really on the spur of the moment."

"All I can say is that if anyone ever deserved it, he did." Three Terrorists ambled down the hall past Sarah's door, chanting "Death to Clown Woman!"

"Okay, fine," said Hyacinth, and stopped crying. "Granted. I can't worry about it forever. But sooner or later they're going to figure out who Clown Woman is. Then there'll be even more violence."

"Better them to be violent against us," said Sarah, "than against people who don't even understand what violence is."

Sarah was busy taking care of herself that semester. This made more sense than what the rest of us were doing, but it did not make for an eventful life. At the same time, a very different American Megaversity student was fighting the same battle Sarah had just won. This student lost. The tale of his losing is melancholy but much more interesting.

Every detail was important in assessing the situation, in determining just how close to the brink Plexor was! The obvious things, the frequent transitions from the Technological universe to the Magical universe, those were child's play to detect; but the evidence of impending Breakdown was to be found only in the minutiae. The extra cold-water pipe; that was significant. What had suddenly caused such a leak to be sprung in the plumbing of Plexor, which had functioned flawlessly for a thousand years? And what powerful benign hand had made the switch from one pipe to the other? What prophecy was to be found in the coming of the Thing of the Earth in the test run of Shekondar? Was some great happening at hand? One could not be sure; the answer must be nested among subtleties. So this one spent many days wandering like a lone thaumaturge through the corridors of the Plex, watching and observing, ignoring the classes and lectures that had become so trivial.

With the help of an obsequious MARS lieutenant he was allowed to inspect the laboratory of the secret railgun experiments. Here he found advanced specialized power supplies from Heimlich Freedom Industries. The lieutenant, a Neutrino member of four years' standing, hooked the output of one power supply to an oscilloscope and showed him the very high and sharp spike of current it could punch out– precisely the impulses a superfast mass driver would need to keep its payload accelerating explosively right up to the end. This one also observed a test of a new electromagnet. It was much larger than those used for the first mass driver, wound with miles of hair-thin copper wire and cooled by antifreeze-filled tubes. A short piece of rail had been made to test the magnet. It was equipped with a bucket designed to carry a payload ten centimeters across! This one watched as a violent invisible kick from the magnet wrenched the bucket to high velocity and slammed it to the cushion at the rail's end; the heavy payload shot out, boomed into a tarp suspended about five feet away, and fell into a box of foam-rubber scraps. It was the same pattern he saw everywhere. A peaceful lunar mining device had, under the influence of Shekondar the Fearsome, metamorphosed into a potent weapon of great value to the forces of Good.

He gave the lieutenant a battlefield promotion to Captain. He wanted to stay and continue to watch, but it had been a long day; he was tired, and for a moment his mind seemed to stop entirely as he stood by the exit.

Then came again the creeping sense of Leakage, impossible to ignore; his head snapped up and to the right, and, speaking across the dimensional barrier, Klystron the Impaler told him to go to dinner.

Klystron the Impaler was only Klystron the Impaler when he was in a Magical universe. The rest of the time he was Chris the Systems Programmer– a brilliant, dashing, young, handsome terminal jockey considered to be the best systems man on the giant self-contained universe-hopping colony, Plexor. From time to time Plexor would pass through the Central Bifurcation, a giant space warp, and enter a Magical universe, fundamentally altering all aspects of reality. Though the structure of Plexor itself underwent little change at these times, everything therein was converted to its magical, pretechnological analog. Guns became swords, freshmen became howling savages, Time magazine became a hand-lettered vellum tome and Chris the Systems Programmer– well, brilliant people like him became sorcerers, swordspeople and heroes. The smarter they were– the greater their stature in the Technological universe– the more dazzling was their swordplay and the more penetrating their spells. Needless to say, Klystron the Impaler was a very great hero-swordsman-magician indeed.

Of course, Plexorians tended to be that way to begin with. Only the most advanced had been admitted when Plexor was begun, and it was natural that their distant offspring today should tend toward the exceptional. Of those lucky enough to be selected for Plexor, only the most adaptable had any stomach for the life once they got there and, every month or so, found their waterbeds metamorphosing into heaps of bearskins. Klystron/Chris liked to think of the place as a pressure cooker for the advancement of humanity.

But even the most perfect machine could not be insulated from the frailty and stupidity of the human mind. In the early days of Plexor every inhabitant had understood the Central Bifurcation, had respected the distinction between technology and magic, and had shown enough discipline to ensure that division. Within the past several generations, though, ignorance had come to this perfect place and Breakdown had begun. Recent generations of Plexorians lacked the enthusiasm and commitment of their forebears and displayed ignorance which was often shocking; recently it had become common to suppose that Plexor was not a free-drifting edosociosystem at all, that it was in fact a planetoidal structure bound to a particular universe. Occasionally, it was true, Plexor would materialize on the ground, in a giant city or a barbarian kingdom. Its makers, a Guild of sorcerers and magicians operating in separate universes through the mediation of Keldor, had created it to be self-sufficient and life-supporting in any habitat, with a nuclear fuel source that would last forever. But to believe that one particular world was always out there was a blindness to reality so severe that it amounted to rank primitivism amidst this sophisticated colony of technocrats. It was, in a word, Breakdown– a blurring of the boundary– and such was the delicacy of that boundary between the universes that mere ignorance of its existence, mere Breakdown-oriented thinking and Breakdown-conducive behavior, was sufficient to open small Leaks between Magic and Technology, to generate an unholy Mixture of the two opposites. It was the duty of the remaining guardians of the Elder Knowledge. such as Klystron/Chris, to expurgate such mixtures and restore the erstwhile purity of the two existences of Plexor.
