“I’m—I’m—” Cameron falters. He is overwhelmed by fear and pity. A bad start, a lamentable start. He trembles. He had not thought it would be anything like this. With an effort he masters himself. Fiercely he says, “I’ve got to know. Was her name Elizabeth?” For an answer the horseman whacks his heels savagely against his mount’s ribs and gallops away, fleeing as though he has had an encounter with Satan.

GO, THE OLD MAN SAID. You know the score. This is how it is: everything’s random, nothing’s fixed unless we want it to be, and even then the system isn’t as stable as we think it is. So go. Go. Go, he said, and, of course, hearing something like that, Cameron went. What else could he do, once he had his freedom, but abandon his native universe and try a different one? Notice that I didn’t say a better one, just a different one. Or two or three or five different ones. It was a gamble, certainly. He might lose everything that mattered to him, and gain nothing worth having. But what of it? Every day is full of gambles like that: you stake your life whenever you open a door. You never know what’s heading your way, not ever, and still you choose to play the game. How can a man be expected to become all he’s capable of becoming if he spends his whole life pacing up and down the same courtyard? Go. Make your voyages. Time forks, again and again and again. New universes split off at each instant of decision. Left turn, right turn, honk your horn, jump the traffic light, hit your gas, hit your brake, every action spawns whole galaxies of possibility. We move through a soup of infinities. If repressing a sneeze generates an alternative continuum, what, then, are the consequences of the truly major acts, the assassinations and inseminations, the conversions, the renunciations? Go. And as you travel, mull these thoughts constantly. Part of the game is discerning the precipitating factors that shaped the worlds you visit. What’s the story here? Dirt roads, donkey-carts, hand-sewn clothes. No Industrial Revolution, is that it? The steam-engine man—what was his name, Savery, Newcomen Watt?—smothered in his cradle? No mines, no factories, no assembly lines, no dark satanic mills. That must be it. The air is so pure here: you can tell by that, it’s a simpler era. Very good, Cameron. You see the patterns swiftly. But now try somewhere else. Your own self has rejected you here; besides, this place has no Elizabeth. Close your eyes. Summon the lightning.

THE PARADE HAS REACHED A disturbing level of frenzy. Marchers and floats now occupy the side streets as well as the main boulevard, and there is no way to escape from their demonic enthusiasm. Streamers cascade from office windows, and gigantic photographs of Chairman DeGrasse have sprouted on every wall, suddenly, like dark infestations of lichen. A boy presses close against Cameron, extends a clenched fist, opens his fingers: on his palm rests a glittering jeweled case, egg-shaped, thumbnail-sized. “Spores from Patagonia,” he says. “Let me have ten exchanges and they’re yours.” Politely Cameron declines. A woman in a blue and orange frock tugs at his arm and says urgently, “All the rumors are true, you know. They’ve just been confirmed. What are you going to do about that? What are you going to do?” Cameron shrugs and smiles and disengages himself. A man with gleaming buttons asks, “Are you enjoying the festival? I’ve sold everything, and I’m going to move to the highway next Godsday.” Cameron nods and murmurs congratulations, hoping congratulations are in order. He turns a corner and confronts, once more, the bishop who looks like Elizabeth’s brother, who is, he concludes, indeed Elizabeth’s brother. “Forget your sins!” he is crying still. “Cancel your debts!” Cameron thrusts his head between two plump girls at the curb and attempts to call to him, but his voice fails, nothing coming forth but a hoarse wordless rasp, and the bishop moves on. Moving on is a good idea, Cameron tells himself. This place exhausts him. He has come to it too soon, and its manic tonality is more than he wants to handle. He finds a quiet alleyway, presses his cheek against a cool brick wall, and stands there breathing deeply until he is calm enough to depart. All right. Onward.

EMPTY GRASSLANDS SPREAD TO THE horizon. This could be the Gobi steppe. Cameron sees neither cities nor towns nor even villages, just six or seven squat black tents pitched in a loose circle in the saddle between two low gray-green hummocks, a few hundred yards from where he stands. He looks beyond, across the gently folded land, and spies dark animal figures at the limits of his range of vision: about a dozen horses, close together, muzzle to muzzle, flank to flank, horses with riders. Or perhaps they are a congregation of centaurs. Anything is possible. He decides, though, that they are Indians, a war party of young braves, maybe, camping in these desolate plains. They see him. Quite likely they saw him some while before he noticed them. Casually they break out of their grouping, wheel, ride in his direction.
He awaits them. Why should he flee? Where could he hide? Their pace accelerates from trot to canter, from canter to wild gallop; now they plunge toward him with fluid ferocity and a terrifying eagerness. They wear open leather jackets and rough rawhide leggings; they carry lances, bows, battle-axes, long curved swords; they ride small, agile horses, hardly more than ponies, tireless packets of energy. They surround him, pulling up, the fierce little steeds rearing and whinnying; they peer at him, point, laugh, exchange harsh derisive comments in a mysterious language. Then, solemnly, they begin to ride slowly in a wide circle around him. They are flat-faced, small-nosed, bearded, with broad, prominent cheekbones; the crowns of their heads are shaven but long black hair streams down over their ears and the napes of their necks. Heavy folds in the upper lids give their eyes a slanted look. Their skins are copper-colored but with an underlying golden tinge, as though these are not Indians at all, but— what? Japanese? A samurai corps? No, probably not Japanese. But not Indians either.
They continue to circle him, gradually moving more swiftly. They chatter to one another and occasionally hurl what sound like questions at him. They seem fascinated by him, but also contemptuous. In a sudden demonstration of horsemanship one of them cuts from the circular formation and, goading his horse to an instant gallop, streaks past Cameron, leaning down to jab a finger into his forearm. Then another does it, and another, streaking back and forth across the circle, poking him, plucking at his hair, tweaking him, nearly running him down. They draw their swords and swish them through the air just above his head. They menace him, or pretend to, with their lances. Throughout it all they laugh. He stands perfectly still. This ordeal, he suspects, is a test of his courage. Which he passes, eventually. The lunatic galloping ceases; they rein in, and several of them dismount.
They are little men, chest-high to him but thicker through the chest and shoulders than he is. One unships a leather pouch and offers it to him with an unmistakable gesture: take, drink. Cameron sips cautiously. It is a thick grayish fluid, both sweet and sour. Fermented milk? He gags, winces, forces himself to sip again; they watch him closely. The second taste isn’t so bad. He takes a third more willingly and gravely returns the pouch. The warriors laugh, not derisively now but more in applause, and the man who had given him the pouch slaps Cameron’s shoulder admiringly. He tosses the pouch back to Cameron. Then he leaps to his saddle, and abruptly they all take off. Mongols, Cameron realizes. The sons of Genghis Khan, riding to the horizon. A worldwide empire? Yes, and this must be the Wild West for them, the frontier, where the young men enact their rites of passage. Back in Europe, after seven centuries of Mongol dominance, they have become citified, domesticated, sippers of wine, theatregoers, cultivators of gardens, but here they follow the ways of their all-conquering forefathers. Cameron shrugs. Nothing for him here. He takes a last sip of the milk and drops the pouch into the tall grass. Onward.

NO GRASS HERE. HE SEES the stumps of buildings, the blackened trunks of dead trees, mounds of broken tile and brick. The smell of death is in the air. All the bridges are down. Fog rolls in off the bay, dense and greasy, and becomes a screen on which images come alive. These ruins are inhabited. Figures move about. They are the living dead. Looking into the thick mist he sees a vision of the shock wave, he recoils as alpha particles shower his skin. He beholds the survivors emerging from their shattered houses, straggling into the smoldering streets, naked, stunned, their bodies charred, their eyes glazed, some of them with their hair on fire. The walking dead. No one speaks. No one asks why this has happened. He is watching a silent movie. The apocalyptic fire has touched the ground here; the
