True Names

— but they were experiencing what no human had ever known before, a sensory bandwidth thousands of times normal. For seconds that seemed without end, their minds were filled with a jumble verging on pain, data that was not information and information that was not knowledge. To hear ten million simultaneous phone conversations, to see the continent's entire video output, should have been a white noise. Instead it was a tidal wave of detail rammed through the tiny aperture of their minds. The pain increased, and Mr. Slippery panicked. This could be the True Death, some kind of sensory burnout — 
Erythrina's voice was faint against the roar, " Use everything, not just the inputs! " And he had just enough sense left to see what she meant. He controlled more than raw data now; if he could master them, the continent's computers could process this avalanche, much the way parts of the human brain preprocess their input. More seconds passed, but now with a sense of time, as he struggled to distribute his very consciousness through the System.
Then it was over, and he had control once more. But things would never be the same: the human that had been Mr. Slippery was an insect wandering in the cathedral his mind had become. There simply was more there than before. No sparrow could fall without his knowledge, via air traffic control; no check could be cashed without his noticing over the bank communication net. More than three hundred million lives swept before what his senses had become.
Around and through him, he felt the other occupant — Erythrina, now equally grown. They looked at each other for an unending fraction of a second, their communication more kinesthetic than verbal. Finally she smiled, the old smile now deep with meanings she could never image before. "Pity the poor Mailman now!"
Again they searched, but now it was through all the civil data bases, a search that could only be dreamed of by mortals. The signs were there, a near invisible system of manipulations hidden among more routine crimes and vandalisms. Someone had been at work within the Venezuelan system, at least at the North American end. The trail was tricky to follow — their enemy seemed to have at least some of their own powers — but they saw it lead back into the labyrinths of the Federal bureaucracy: resources diverted, individuals promoted or transferred, not quite according to the automatic regulations that should govern. These were changes so small they were never guessed at by ordinary employees and only just sensed by the cops. But over the months, they added up to an instability that neither of the two searchers could quite understand except to know that it was planned and that it did the status quo no good.
"He's still too sharp for us, Slip. We're all over the civil nets and we haven't seen any living sign of him; yet we know he does heavy processing on Earth or in low orbit."
"So he's either off North America, or else he has penetrated the … military."
"I bet it's a little of both. The point is, we're going to have to follow him."
And that meant taking over at least part of the US military system. Even if that was possible, it certainly went far beyond what Virginia and her friends had intended. As far as the cops were concerned, it would mean that the threat against the government was tripled. So far he hadn't detected any objections to their searching, but he was aware of Virginia and her superiors deep in some kind of bunker at Langley, intently watching a whole wall full of monitors, trying to figure out just what he was up to and if it was time to pull the plug on him.
Erythrina was aware of his objections almost as fast as he could bring them to mind. "We don't have any choice, Slip. We have to take control. The Feds aren't the only thing watching us. If we don't get the Mailman on this try, he is sure as hell going to get US."
That was easy for her to say. None of her enemies yet knew her True Name. Mr. Slippery had somehow to survive two enemies. On the other hand, he suspected that the deadlier of those enemies was the Mailman. "Only one way to go and that's up, huh? Okay, I'll play."
They settled into a game that was familiar now, grabbing more and more computing facilities, but now from common Europe and Asia. At the same time, they attacked the harder problem — infiltrating the various North American military nets. Both projects were beyond normal humans or any group of normal humans, but by now their powers were greater than any single civil entity in the world.
The foreign data centers yielded easily, scarcely more than minutes' work. The military was a different story. The Feds had spent many years and hundreds of billions of dollars to make the military command and control system secure. But they had not counted on the attack from all directions that they faced now; in moments more, the two searchers found themselves on the inside of the NSA control system — and under attack! Impressions of a dozen sleek, deadly forms converging on them, and sudden loss of control over many of the processors he depended on. He and Erythrina flailed out wildly, clumsy giants hacking at fast-moving hawks. There was imagery here, as detailed as on the Other Plane. They were fighting people with some of the skills the warlocks had developed — and a lot more power. But it was still an uneven contest. He and Erythrina had too much experience and too much sheer processing mass behind them. One by one, the fighters flashed into incandescent destruction.
He realized almost instantly that these were not the Mailman's tools. They were powerful, but they fought as only moderately skilled warlocks might. In fact, they had encountered the most secret defense the government had for its military command and control. The civilian bureaucracies had stuck with obsolete data sets and old-fashioned dp languages, but the cutting edge of the military is always more willing to experiment. They had developed something like the warlocks' system. Perhaps they didn't use magical jargon to describe their computer/human symbiosis, but the techniques and the attitudes were the same. These swift-moving fighters flew against a background imagery that was like an olive drab Other Plane.
Compared to his present power, they were nothing. Even as he and Erythrina swept the defenders out of the "sky," he could feel his consciousness expanding further as more and more of the military system was absorbed into their pattern. Every piece of space junk out to one million kilometers floated in crystal detail before his attention; in a fraction of a second he sorted through it all, searching for some evidence of alien intelligence. No sign of the Mailman.
The military and diplomatic communications of the preceding fifty years showed before the light of their minds. At the same time as they surveyed the satellite data, Mr. Slippery and Erythrina swept through these bureaucratic communications, looking carefully but with flickering speed at every requisition for toilet paper, every "declaration" of secret war, every travel voucher, every one of the trillions of pieces of "paper" that made it possible for the machinery of state to creak forward. And here the signs were much clearer: large sections were subtly changed, giving the same feeling the eye's blind spot gives, the feeling that nothing is really obscured but that some things are simply gone. Some of the distortions were immense. Under their microscopic yet global scrutiny, it was obvious that all of Venezuela, large parts of Alaska, and most of the economic base for the low satellite net were all controlled by some single interest that had little connection with the proper owners. Who their enemy was was still a mystery, but his works loomed larger and larger around them.
