The power grew. The wizards finished speaking the spell, which was, after all, a fairly simple thing, describing how one wanted something to be farther away. Three thousand voices and minds, or more, said the last words of the wizard’s knot together, and fell silent. But between those two out in the middle of the spell diagram, the power kept going back and forth. Nguyet’s and Tuyet’s outlines began to shimmer as if Nita were seeing them through a haze of heat. The sense of something actively dangerous going on started to build inside Nita, so that she very much wanted to get up and back away. But there was nowhere to back away to, and, anyway, everybody else, no matter how alarmed they looked, was holding very still. She shot a glance at Kit, who was sitting there with his fists clenched, tense but unmoving. Behind him, Ponch had begun to whimper softly.
Back and forth between the twychild the power went, back and forth. Between Nguyet and Tuyet, the air had begun to burst out in small sparks of power, wizardly energy looking for somewhere to discharge itself but not finding any way to escape. The power trapped in the air inside the spell-circle built and built, until Nita’s hair started to stand on end and her skin prickled with it.
Inside the circle, the reflected and re-reflected power just kept building and building; the sparkles and flares of its attempted discharge got brighter and brighter, spreading away from the corridor between the twychild and right through the circle, beating right up against the boundaries of it like waves against a storm wall. The power climbed the invisible walls, held in by them and raving against them; it arched up and over until it completely filled the spell’s dome. Inside the dome, the fog of concentrated, concentrating power thickened, the discharge flashes filling every cubic foot of air until Tuyet and Nguyet couldn’t be seen at all. Whether she could see them or not, Nita concentrated on not even twitching, not doing anything that might distract the wizards inside the circle.
And then the spell boundary directly above them vanished.
Everything inside the dome went furiously, blindingly white. Nothing could have prepared Nita for the huge flare of wizardly fire that poured up and out of Daedalus crater, up and out into space, and fled, faster than any normal light, out past Earth’s orbit—three thousand wizards’ worth of wizardry, multiplied who knew how many times. Nita sensed rather than saw the wavefront of the wizardry spilling out across local space like the expanding surface of a blown bubble, speeding away, spreading, pushing before it everything it met. A storm of the micrometeorites that followed Earth around in its orbit vaporized as it impacted them; the ions themselves glowed and sheeted across the surface of the outward-speeding sphere like flattened-out auroras.
Nita tried to rub some sight back into her eyes, craning her neck upward. The spell went blasting outward, a rainbow bubble half the width of the sky, growing fainter as it went but not getting any less strong; it was accelerating as it got closer to the Pullulus. All around her, the other wizards were looking up, watching the spell get closer and closer to its target. A murmur of excitement started to go up among them as some of them started to feel what Nita did—a strange roiling out in the darkness, a sense of something that was darkly alive reacting with fear to something threatening that was coming at it faster and faster.
Nita looked out across the spell diagram, saw Nguyet and Tuyet standing there in their circles, shaking with effort, but watching what was happening with all the others. Out in the darkness, something was furious, something was frightened.
She held her breath. There was a long, long pause, and then the outflung boundary of the wizardry flared as it struck the substance it had been intended for. Everyone who had been connected to that wizardry felt the resistance of that target in their bones. But the wizardry kept going. The light of it flared in all their minds as it hit the Pullulus, pushed it outward, farther outward. A second later, the wizards started to cheer—
—and the wave front flared out, vanishing.
Nita stared up, unbelieving.
The Pullulus was still there. That darkness swallowed the last of the rainbow, snuffed it out, absorbed all the power that had been poured into it…
…and plunged inward through the orbit of Mars, faster than light, faster than darkness, heading for the Earth.
Beside Nita, Kit looked up at the rapidly darkening sky in complete shock.
Ponch put his head under Kit’s arm.
