“You're the physicist, you idiot boy. Haven't you ever heard of the uncertainty principle?”

“Particle physics. Philotic physics.”

“Mob physics, Grego. You never owned them. They owned you. And now they've used you up and they're going to destroy the forest of our best friends and advocates among the pequeninos and what will any of us do then? It's war between humans and pequeninos, unless they have inhuman self-restraint, and it will be our fault.”

“Warmaker killed Quim.”

“A crime. But what you've started here, Grego, this is an atrocity.”

“I didn't do it!”

“Bishop Peregrino counseled with you. Mayor Kovano warned you. I begged you. And you did it anyway.”

“You warned me about a riot, not about this–”

“This is a riot, you fool. Worse than a riot. It's a pogrom. It's a massacre. It's baby-killing. It's the first step on the long terrible road to xenocide.”

“You can't blame all that on me!”

Her face is so terrible in the moonlight, in the light from the doors and windows of the bars. “I blame on you only what you did. You started a fire on a hot, dry, windy day, despite all warnings. I blame you for that, and if you don't hold yourself responsible for all the consequences of your own acts, then you are truly unworthy of human society and I hope you lose your freedom forever.”

She's gone. Where? To do what? She can't leave him alone here. It's not right to leave him alone. A few moments ago, he was so large, with five hundred hearts and minds and mouths, a thousand hands and feet, and now it was all gone, as if his huge new body had died and he was left as a quivering ghost of a man, this single slender worm of a soul bereft of the powerful flesh it used to rule. He had never been so terrified. They almost killed him in their rush to leave him, almost trampled him into the grass.

They were his, though, all the same. He had created them, made a single mob of them, and even though they had misunderstood what he created them for, they were still acting according to the rage he had provoked in them, and with the plan he had put in their minds. Their aim was bad, that's all– otherwise they were doing exactly what he had wanted them to do. Valentine was right. It was his responsibility. What they did now, he had done as surely as if he were still in front of them leading the way.

So what could he do?

Stop them. Get control again. Stand in front of them and beg them to stop. They weren't setting off to burn the distant forest of the mad fathertree Warmaker, they were going to slaughter pequeninos that he knew, even if he didn't like them much. He had to stop them, or their blood would be on his hands like sap that couldn't be washed or rubbed away, a stain that would stay with him forever.

So he ran, following the muddy swath of their footprints through the streets, where grass was trampled down into the mire. He ran until his side ached, through the place where they had stopped to break down the fencewhere was the disruption field when we needed it? Why didn't someone turn it on? –and on to where already flames were leaping into the sky.

“Stop! Put the fire out!”

“Burn!”

“For Quim and Christ!”

“Die, pigs.”

“There's one, getting away!”

“Kill it!”

“Burn it!”

“The trees aren't dry enough– the fire's not taking!”

“Yes it is!”

“Cut down the tree!”

“There's another!”

“Look, the little bastards are attacking!”

“Break them in half!”

“Give me that scythe if you aren't going to use it!”

“Tear the little swine apart!”

“For Quim and Christ!”

Blood sprays in a wide arc and spatters into Grego's face as he lunges forward, trying to stop them. Did I know this one? Did I know this pequenino's voice before it was torn into this cry of agony and death? I can't put this back together again, they've broken him. Her. Broken her. A wife. A never-seen wife. Then we must be near the middle of the forest, and that giant must be the mothertree.

“Here's a killer tree if I ever saw one!”

Around the perimeter of the clearing where the great tree stood, the lesser trees suddenly began to lean, then toppled down, broken off at the trunks. For a moment Grego thought that it was humans cutting them down, but now he realized that no one was near those trees. They were breaking off by themselves, throwing themselves down to their deaths in order to crush the murdering humans under their trunks and branches, trying to save the mothertree.

For a moment it worked. Men screamed in agony; perhaps a dozen or two were crushed or trapped or broken under the falling trees. But then all had fallen that could, and still the mothertree stood there, her trunk undulating strangely, as if some inner peristalsis were at work, swallowing deeply.

“Let it live!” cried Grego. “It's the mothertree! She's innocent!”

But he was drowned out by the cries of the injured and trapped, and by the terror as they realized that the forest could strike back, that this was not all a vengeful game of justice and retribution, but a real war, with both sides dangerous.

“Burn it! Burn it!” The chant was loud enough to drown out the cries of the dying. And now the leaves and branches of the fallen trees were stretched out toward the mothertree; they lighted those branches and they burned readily. A few men came to their senses enough to realize that a fire that burned the mothertree would also burn the men pinned under the fallen brothertrees, and they began to try to rescue them. But most of the men were caught up in the passion of their success. To them the mothertree was Warmaker, the killer; to them it was everything alien in this world, the enemy who kept them inside a fence, the landlord who had arbitrarily restricted them to one small plot of land on a world so wide. The mothertree was all oppression and all authority, all strangeness and danger, and they had conquered it.

Grego recoiled from the screaming of the trapped men who watched the fire approaching, from the howls of the men the fire had reached, the triumphant chanting of the men who had done this murder. “For Quim and Christ! For Quim and Christ!” Almost Grego ran away, unable to bear what he could see and smell and hear, the bright orange flames, the smell of roasting manflesh, and the crackling of the living wood ablaze.

But he did not run. Instead he worked beside the others who dashed forward to the very edge of the flame to pry living men out from under the fallen trees. He was singed, and once his clothing caught on fire, but the hot pain of that was nothing, it was almost merciful, because it was the punishment that he deserved. He should die in this place. He might even have done it, might even have plunged himself so deeply into the fire that he could never come out until his crime was purged out of him and all that was left was bone and ash, but there were still broken people to pull out of the fire's reach, still lives to save. Besides, someone beat out the flames on his shoulder and helped him lift the tree so the boy who lay under it could wriggle free and how could he die when he was part of something like this, part of saving this child?

“For Quim and Christ!” the boy whimpered as he crab-crawled out of the way of the flames.

Here he was, the boy whose words had filled the silence and turned the crowd into this direction. You did it, thought Grego. You tore them away from me.

The boy looked up at him and recognized him. “Grego!” he cried, and lunged forward. His arms enfolded Grego around the thighs, his head pressed against Grego's hip. “Uncle Grego!”

It was Olhado's oldest boy, Nimbo.

“We did it!” cried Nimbo. “For Uncle Quim!”

The flames crackled. Grego picked up the boy and carried him, staggering out of the reach of the hottest flames, and then farther out, into the darkness, into a place where it was cool. All the men were driven this way, the flames herding them, the wind driving the flames. Most were like Grego, exhausted, frightened, in pain from the fire or helping someone else.
