weapon for the first time. If he felt any elation on seeing his gun for the first time, none of it was visible on his face. He looked, instead, ashen â as if the years had suddenly reclaimed what the Waymakers had given him. âAll they could do was keep the stars in check, keep them from spiraling any closer. So they built the Brittlestar, a vast machine with only one function: to constantly nudge the orbits of the neutron stars at its heart. For every angstrom that the stars fell toward each other, the Brittlestar pushed them an angstrom apart. And it was designed to keep doing that for a million years, until the Waymakers found a way to shift the entire binary beyond the Galaxy. You want to know how they kept pushing them apart?â
Sora nodded, though she thought she half-knew the answer already.
âTiny black holes,â Merlin said. âAccelerated close to the speed of light, each black hole interacting gravitationally with the binary before evaporating in a puff of pair-production radiation.â
âJust the same way the gun functions. Thatâs no coincidence, is it?â
âThe gun â what we call the gun â was just a component in the Brittlestar; the source of relativistic black holes needed to keep the neutron stars from colliding.â
Sora looked around the room. âAnd these people stole it?â
âLike I said, they were closer to the Waymakers than us. They knew enough about them to dismantle part of the Brittlestar, to override its defenses and remove the mechanism they needed to win their war.â
âBut the Brittlestar . . .â
âHasnât been working properly ever since. Its capability to regenerate itself was harmed when the subsystem was stolen, and the remaining black-hole generating mechanisms canât do all the work required. The neutron stars have continued to spiral closer together â slowly but surely.â
âBut you said they were only a few thousand years from collision . . .â
Merlin had not stopped working the controls in all this time. The gun had come closer, seemingly oblivious to the ordinary laws of celestial mechanics. Down below, the planetary surface had returned to normality, except for a ruddier hue to the storm.
âMaybe now,â Merlin said, âyouâre beginning to understand why I want the gun so badly.â
âYou want to return it, donât you. You never really wanted to find a weapon.â
âI did, once.â Merlin seemed to tap some final reserve of energy, his voice growing momentarily stronger. âBut now Iâm older and wiser. In less than four thousand years the stars meet, and it suddenly wonât matter who wins this war. Weâre like ignorant armies fighting over a patch of land beneath a rumbling volcano!â
Four thousand years, Sora thought. More time had passed since she had been born.
âIf we donât have the gun,â she said, âwe die anyway â wiped out by the Huskers. Not much of a choice, is it?â
âAt least
something
would survive. Something that might even still think of itself as human.â
âYouâre saying that we should capitulate? That we get our hands on the ultimate weapon, and then not
use
it?â
âI never said it was going to be easy, Sora.â Merlin pitched forward, slowly enough that she was able to reach him before he slumped into the exposed circuitry of the console. His coughs were loud in her helmet. âActually, I think Iâm more than winded,â he said, when he was able to speak at all.
âWeâll get you back to the ship; the proctors can help . . .â
âItâs too late, Sora.â
âWhat about the gun?â
âIâm . . . doing something rather rash, in the circumstances. Trusting it to you. Does that sound utterly insane?â
âIâll betray you. Iâll give the gun to the Cohort. You know that, donât
