The moon was different. That was the first thing Beth Eden Jones noticed as the
Ukelwydd
sailed toward the Earth, still decelerating, kernel drive burning bright.
It was a chance navigational alignment that brought the incoming ship close to the satellite, close enough for the kernel energies to cast a glow on the surface. On the dark side lights were scattered, and domes reflected the ship's fire like droplets of mercury. But when the day side opened up, with the moon receding behind the Earthbound ship, even Bethâa stranger to the solar system until she stepped through a Hatch from Per Ardua to Mercury at age twentyâcould see how the ancient terrain was disfigured. The smooth grayness of the
maria
, the seas, was gouged and scarred with immense rectilinear workings, and the whole face was masked by rays from brilliant, sharply defined new craters. The
maria
landforms were obviously artificial, the result of centuries of human mining for resources, here on this version of the moon. It took a while for Beth to understand that the new craters, the bright rays, were human-made features too: the scars, not of industry, but of war.
Having passed the moon, the ship turned for Earth, a button of light in the sky. But again Beth could immediately see differences from the world she remembered, even from this distance. There was no gleam of ice, for one thing, at either pole. And whole swaths of the planet, in central America, central Africa, Australia, were bare of life, as if the green had worn away to expose the rocky bones of the world.

The
Ukelwydd
, with the ruin of the
Tatania
in tow and the hulk ship's tenfold crew aboard, settled neatly into a high-inclination orbit around Earth, or Terra as the home world was called by the Brikanti. The crew of the ISF ship was restricted to their sparse quarters for a full day, as the Brikanti went through their arrival protocols.
After this brief confinement, Ari Guthfrithson, the ship's leading
druidh
, invited Beth to join him to view the world, for soon the orbital pass would take the ship over Britain and north Europe, the home of the Brikanti and their allies, including Ari's own people.
Beth was pleased to see Ari. She felt she had grown relatively close to this calm scholar in the days they had spent on this ship. He was younger than she was, but not by much. He wasn't exactly handsome, but like all the Brikanti crew he seemed to be exceptionally well groomed, with neat hair and finely shaped sideburnsâshe had glimpsed him using a portable kit, scissors, a nail file. She was attracted to him, she thought, if only faintly.
And today the general mood was good. The
Ukelwydd
crew seemed relaxed as they switched over from flight mode to less demanding orbital operations.
“Plus,” said Lex McGregor as he joined Beth and Ari at a big observation window, “maybe they are looking forward to getting rid of us. I know the military. The sooner they can kick a problem upstairs the happier they will be.”
Ari's voice, softly translated for Beth through Earthshine's systems via her earpiece, was calm, melodious. “Actually ship's crew are not used to dealing with people directly. In space conflicts, a personal encounter with the enemy is rare; the defeated rarely survive to become prisoners. And of course your Earthshine, whose nature we cannot understand, represents a double conceptual problem for us.”
“Well, I'm sorry about that,” McGregor said drily. “But he is the reason we're all here in the first place. The objective of the flight of the poor old
Tatania
was specifically to save Earthshine from the consequences of our own upcoming war.” He glanced down at the world, over which the ship drifted silently. “Though whether by bringing Earthshine to this place really counts as âsaving' himâI suppose I'm relieved I'll never have to justify that to my superiors, wherever
they
are . . . I'm sorry, I'm maundering.”
Ari said, “Your destiny at a higher level than that has not yet been decided.”
McGregor frowned. “I don't understand. This is a Brikanti ship. I don't know anything about your government, your empireâwhateverâbut surely we're under your protection.”
“I'm afraid it is more complicated than that.” Ari gestured. “Look around.”
And when Beth looked away from the bright surface of the planet she saw an array of brilliant, unwinking stars against the dark background of space.
Lex McGregor whistled. “Wow. Space habitats. I see tori, cylinders, platformsâmirrors, antennas . . .” He clenched a fist. “We've barely been allowed near a window. I never even noticed all this junk before.”
“Junk?” Ari smiled. “I have been told that, where you come from, space is much less populated, comparatively. We find that difficult to understand. With kernel-drive ships it is easy to haul vast loads into orbit, or to ship materials in from such sources as Luna or the Tears of Ymir.”
“But, Ari, theyâumm,
we
âare more wary of kernels than you are. Kernel drives aren't allowed on the Earth. Nowhere closer than the far side of the moon, where Penny Kalinski and her sister once worked. Of course, when the final war came, all bets were off.”
“But I point out that the hardware you see in space around us represents the various forces who have taken an interest in you.”
Beth said, “You mean the Romans, the Xin?”
“I do.” Ari studied her, his face open, inquisitive. “I still know little of your own history. What hints I have heard are fascinatingâthe differences from our own. For now, you need to understand this. From what I have gathered, your history was rather more complex than ours has been. Fragmented. Essentially our world, and now the worlds beyond Terra, have been dominated by the rise of two powerful empires, Rome and Xin. Though other polities have come and gone, those two great poles of power have competed for control of the great landmasses of Asia and Europa for two thousand years. And for the last thousand years or more they have contended over the territories of the rest of the world also. The only significant exception has been my own federation, the Brikanti. Starting with a Pritanike that stayed independent of Rome, the Brikanti have managed to retain a kind of land empire of their own.”
He studied their faces. “Terrible wars have been fought, on this world and elsewhere. Why, the battered face of Luna is a reminder of that. It is said that when the war up there was at its height, and the face of the satellite burned in the sky, a hail of debris, rocks from the great lunar detonations, rained down on Terra. Those accidental rock falls could not be distinguished from purposeful attacks, and a new wave of war was initiated on Terra itself. However, war and competition drove innovation. In many ways, it is clear, my culture is less technologically advanced than yoursâbut not in others.
“And we survive, and poor Terra, almost as battered and scarred as Luna, has survived as an abode for humanity. This is because we, the competing powers of Terra, have found ways, if not to cooperate, at least to manage our conflicts. To sublimate them into angry diplomacy.”
McGregor said, “Are you saying we are now the subject of this âangry diplomacy'?”
Ari sighed. “The whole world saw the
Ukelwydd
come sailing in with the wreck of a ship of unknown origin. Our crew is riddled with spies for Xin and Rome. Of course it is; it is to be expected. You represent treasure, or perhaps danger, of unknown potential. We Brikanti spotted you first, and showed the initiative to retrieve you, but that is not to say that Xin and Rome are happy for us to keep you to ourselves. And as a result, right now, this ship, and you, are the subject of scrutiny. And as they watch us, they watch each other too.”
McGregor grunted. “And everybody is armed to the teeth.”
“That's the idea. The fact that there is a native Xin among you, or so we would classify Jiang Youwei, makes the situation that much more complex;
all
sides feel they have a claim. At some point the
trierarchus
, as the command authority on the spot, will need to decide whether it is worth the risk of trying to transport you to Brikanti territory on the ground, or else to give you up to either Rome or Xinâor even to cast you adrift in your
Tatania
and let them fight it out over you. For we Brikanti, you see, are a small and nimble power who strive to stay safe by not being trodden on by either of our world's lumbering giants . . .”
Penny Kalinski joined them now, entering through the door at the back of the cabin. Swimming easily in the absence of gravity, she looked comfortable in a loose-fitting Brikanti costume of tunic and trousers. She was carrying a slate, and sipping something from a covered pottery mug. “Watered-down mead,” she said to Beth. “Pleasant stuff.”
Beth had to smile. “You look as if you fit in here, Penny.”
“Well, what can you do but make the best of it? I doubt we're going home any time soon. Even if âhome' still exists, in any meaningful sense. So what's going on? I heard we were due to pass over Britain; I wanted to come see.”
Lex McGregor did a double take, turned to the panorama of the world below, and frowned at what he saw. “Really?
That's
Britain? What the hell?”
Beth, a stranger to Earth, had comparatively little preconception about what she expected to see, looking down on Britain / Pritanike. She saw a kind of archipelago, a scatter of islands off the shore of a greater continent to the east. There was a grayish urban tangle laid over the green-brown of the countryside on the eastern coast of the larger of the islands, nearest the continent; she saw the glitter of glass and metal, arrow-straight roads. And in the mountainous country of an island to the far north she saw tremendous rectangular workings that looked as if they might rival the minefields of the lunar
maria
.
Lex said grimly, “I was born in England. The southern counties, Angleterre. I have seen my home country from space many times. But I do not recognize
that.
Half of it's missing altogether.”
Penny touched his shoulder. “History's been different here, Lex. Rome in the west never fell, apparently. Here, they industrialized centuries before we did. With the consequences you'd expect.”
“Greenhouse gases. Deforestation. Sea level rises?”
“That's it. It will all have gone a lot farther and a lot earlier than in our timeline.
We
had the great twenty-first century crisis of the climate Jolts, the heavy-handed repair work of the Heroic Generation. Maybe here, as it unfolded more slowly, they understood it all lessâmaybe they cared lessâand just adapted to it. I think we can expect to see the coastlines transformed all around the world. Lowlands lost, like south and east England here.”
McGregor squinted. “That big sprawl in northern England looks like it's centered on York.”
“That is Eboraki,” said Ari. “The capital of an independent Pritanike since the days of Queen Kartimandia herself, she who defied Rome. It has always been a city of war. Later, in the early days of contact between my own ancestral people and the Brikanti, for some years Eboraki was held by us. It was a Scand city, not a Brikanti one.”
Penny grinned. “But all that's a long time ago. Forgive and forget?”
“At least we Brikanti and Scand loathe each other less than we loathe the Romans and the Xin. Now Eboraki is the capital of a world empireâthough we have no emperors.”
Lex said, “The development on the scraps of high ground to the south of the Thames, beyond the Isle of Dogs. That might be some version of London.”
“That is Lund,” Ari said. “The most obvious gateway to Europa, and the Roman provinces. The town was a petty community before contact with the Romans; there was no particular purpose for it. After Kartimandia it became a trading hub with the Empire, and the nearest to a Roman city in Pritanike. But it was always dwarfed by Eboraki.”
McGregor pointed. “And what the hell did you do to Scotland?”
Ari frowned. “We know it as Kaledon. An arena of heroic engineering.”
“It looks like you demolished mountains,” McGregor said. “Some areas look like they've been
melted
.”
“Some have been,” Ari said. “A kernel-drive spacecraft, landing or taking off, generates rather a lot of heat.”
“My God,” Penny said. “They really have brought kernel technology down to the face of the Earth. All that heat energy dumped into the ground, the air. It's a wonder they haven't flipped the whole damn planet into some catastrophic greenhouse-warming event, into a Venus.”
“Maybe,” Lex said, “they were lucky. They got away with it.
Just
. Perhaps there are other timelines where precisely that happened. Does that make sense, Kalinski? If there are two timelines, why not many?”
“Or an infinite number.” She grinned, lopsided. “That had occurred to me too. You're thinking like a scientist, McGregor.”
“I'll cut that out immediately.”
Ari followed this exchange closely.
Now the island cluster was passing away to the northwest, and the ship was sailing over the near continentâGaul to the Romans and the Brikanti, France to the crew of the
Tatania
. The countryside, where it was spared by the sea-level rise, glowed with urbanization. But on the track of a broad river Beth made out a neat circular feature, a set of rays spanning out from it, a lunar crater partially overgrown by the green. She pointed. “What's that?”
Ari said, “Once a major city of the Roman province. Destroyed in a war some centuries back, by a Xin missile that got through the local defenses.”
Penny said, “The missileâkernel-tipped? It was, wasn't it? So it's true. You people don't just use kernels as sources of power on Earth. You actually use them in weapons, to fight your Iron Age wars.”
