The Towers were held by the best-armed groups. The Axis held E and F, the GASF held D, the administration anti-Terrorist squads B and C, and TUG held A, H, and G, prompting Hyacinth to remark that if this were tic-tac-toe the TUG would have won. The towers were easy to hold because access was limited; if you blocked shut the four outer fire stairs of each wing, you could control the only entrances to the tower with a handful of soldiers in the sixth-floor lobby. The base of the Plex was a bewildering 3-D labyrinth. Here things were much less stable as several groups struggled for control of useful ground, such as bathrooms, strategic stairways, rooms with windows and so forth. Many of these were factions that had split away from the Terrorists, finding the strict hierarchy and tight restrictions intolerable. Other important groups were made up of inner-city financial-aid students, who at least knew how to take care of themselves; one gang of smalltowners from the Great Plains, also adept at mass violence; the hockey-wrestling coalition; and the Explorer post, which had a large interlocking membership with the ROTC students.
Those who were not equipped or inclined to fight fared poorly. Most ended up trapped in the towers for the duration, where all they could do was watch TV and reproduce. Escape from the Plex was impossible, because the nuclear Terrorists allowed no one to approach it, and snipers in the Axis towers made perilous the dash from the Main Entrance. Those who could not make it to the safety of a tower were not wanted by the bands of fighters in the Base, and so had to wander as refugees, most ending up in the Library. It was a very, very bad time to be an unescorted woman. We tried to make raids against weaker bands in order to rescue some of these unfortunates, but only retrieved thirty or so.
Fire in the Plex was not the problem it had been feared to be. The plumbing still worked reasonably well and most people had enough sense to use the fire hoses. Many areas were smoky for days, though, to the point of being hostile to life, and bands driven from their own countries by smoke accounted for a good deal of the fighting. The food problem was minor because the Red Cross was allowed to distribute it in the building. Unfortunately there was no way to remove garbage, so it piled up in lobbies and stairwells and elevator shafts. Insects, invading through windows that had been broken out or removed to vent smoke, grew fruitful and multiplied; but this plague then abated, as the bat population swelled enormously to take advantage of the explosion in their food supply. By the end of the crisis, the top five floors of E Tower had been evacuated to make room for bats, who were moving down the tower at the rate of one floor every three days.
There were stable areas where well-armed people settled in and organized themselves. The Burrows were exceptionally stable, brilliantly organized by Fred Fine, and Virgil's Science Shop was an enclave of stability within that. About twenty people lived in the Shop; we slept on floors and workbenches, and cooked communally on lab burners. Fred Fine allowed us this autonomy for one reason: Shekondar the Fearsome/JANUS 64 had selected Virgil as his sole prophet.
Of course it was not really so simple. It was actually the Worm, and Virgil's countermeasures. As Virgil explained it, he had signed on to his terminal on March 31 to find a message waiting: WELL MET WORM-HUNTING MERCENARY. YOU ARE ADEPT. LET US HOPE YOU ARE WELL PAID. SO FAR I HAVE ONLY FLEXED MY MUSCLES. NOW BEGINS THE DUEL.
The next day, of course, civilization had fallen. As soon as Virgil had been sure of this, he had signed on to find that his terminal had been locked out of the system by the Worm. This he had anticipated, and so he calmly proceeded to the Operator's Station, ejected Consuela and signed on there under a fake ID. Virgil had then commandeered six tape drives (to the dismay of the hackers who were using them) and mounted six tapes he had prepared for this day. He went to the Terminal Room, where sat hundreds of terminals in individual carrels. Here Virgil signed on to eighteen terminals at once, using fake accounts and passwords he had been keeping in reserve. On each terminal he set in motion a different program-- using information stored on the six special tapes. Each of these programs looked like a rather long but basically routine student effort, the sort of thing the Worm had long since stopped trifling with. But each did contain lengthy sections of machine code that had no relevance to the program proper.
Virgil returned to the Operator's Station and entered a single command. Its effect was to draw together the reins of the eighteen sham programs, to lift out, as it were, all those long machine code sections and interleave them into one huge powerful program that seemed to coalesce out of nowhere, having already penetrated the Worm's locks and defenses. This monster program, then, had calmly proceeded to wipe out all administrative memory and all student and academic software, and then to restructure the Operator to suit Virgil's purposes. It all went-- payroll records, library overdues, video-game programs. From the computer's point of view, American Megaversity ceased to exist in the time it took for a micro-transistor to flip from one state to the other.
