Take ten billion people and say that, out of every million of them, one—just one—is different. He has a talent for survival; call him Wolf. Ten thousand of him in a world of ten billion.

Squeeze them, freeze them, cut them down. Let old Rejoice in Messias loom in the terrifying sky and so abduct the Earth that the human race is decimated, fractionated, reduced to what is in comparison a bare handful of chilled, stunned survivors. There aren't ten billion people in the world any more. No, not by a factor of a thousand. Maybe there are as many as ten million, more or less, rattling around in the space their enormous Elder Generations made for them.

And of these ten million, how many are Wolf?

Ten thousand.

"You understand, Tropile?" said Haendl. "We survive. I don't care what you call us. The sheep call us Wolves. Me, I kind of call us Supermen. We have a talent for survival."

Tropile nodded, beginning to understand. "The way I survived the House of the Five Regulations."

Haendl gave him a pitying look. "The way you survived thirty years of Sheephood before that. Come on."

It was a tour of inspection. They went into a building, big, looking like any other big and useful building of the ancients, gray stone walls, windows with ragged spears of glass. Inside, though, it wasn't like the others. Two sub-basements down, Tropile winced and turned away from the flood of violet light that poured out of a quartz bull's-eye on top of a squat steel cone.

"Perfectly harmless, Tropile—you don't have to worry," Haendl boomed. "Know what you're looking at? There's a fusion reactor down there. Heat. Power. All the power we need. Do you know what that means?"

He stared soberly down at the flaring violet light of the inspection port.
