The methane fog on Bayou-7 did not roll in; it simply was, as though the atmosphere had always been this way and the planet had simply forgotten to remove it. Commander Elias Voss watched it coat the observation dome with a pale green shimmer and thought, with the detached amusement of a man who had stopped caring about things, that it looked like the inside of a lung.

Three months he had been on this planet. Three months since the Federal Court had stripped him of his command, his rank, his name — well, not his name, they had not taken that. They had taken the part of him that mattered, the part that knew things the Federation did not want known. The charges were vague: "Unauthorized historical research." "Dissemination of unverified data." The real charge, he suspected, was that he had looked at the Federation's official history long enough to notice the gaps — the places where whole civilizations had been erased not with malice but with the casual indifference of a child crossing out words in a book.

"Commander," a voice said from the corridor outside the dome. "You're at it again."

Jax O'Malley — twenty-three years old, mixed blood, the particular restlessness of someone whose father was from Earth and whose mother was born under a different sky — leaned in the dome's entrance. His hair was the color of tarnished copper and his eyes were the color of something looking for a reason to exist. He was cargo crew by trade, which meant he was excellent at finding things in spaces where nothing should have been found. This made him useful and dangerous, two qualities that in Jax's case were indistinguishable.

"It's not 'again,'" Elias said. "It's the first time this cycle."

"That's what you said last cycle."

"Then my memory of last cycle is corrupted."

Jax smiled. It was a crooked smile, asymmetrical, the kind that comes from a childhood spent making faces at yourself in broken mirrors. "Come on. Ashcroft says he knows where the old maps are. The ones that show the crater district."

The name landed between them like a stone in still water. Ashcroft was the old man who lived in Section C of the station — or, more accurately, the old man who lived in a cluster of interconnected modules that he called a house, though it was more accurately a fortress of salvaged parts and repurposed machinery. He claimed to remember the station before the collapse, before the Federation came and called it "Bayou-7" and began cataloging it as a resource to be harvested. On a frontier world where memory was a currency more valuable than oxygen, this made him either the most dangerous man on the planet or the most harmless. Elias had not yet decided.

They found Ashcroft in his greenhouse — a collection of grow-lights and hydroponic trays arranged in the shape of a question mark. The old man was standing in the center of it, his hands clasped behind his back, his eyes on something Elias could not see.

"You brought the archaeologist," Ashcroft said. It was not a question.

"I brought someone who might know what he's talking about," Jax said. "If he's talking about anything."

Ashcroft turned. His face was a map of wrinkles that did not follow the normal patterns of aging — they were too deep, too deliberate, as though each line had been carved with intention rather than time. "The maps are not paper," he said. "They are in the ground. In the methane. In the ice that used to be ocean. If you know where to look."

Elias felt the familiar tightening in his chest — not hope, he would not insult himself with that word, but something close to it. The curiosity of a man who has spent his entire life learning that the world is not what it seems and is still, somehow, not disappointed.

"What did you find?" he asked.

Ashcroft reached behind him and produced a data slate — old, scratched, the kind of thing that should not have had any charge left but somehow still did. On its surface was a hand-drawn map. The contours were wrong by Federation standards — the coordinates did not match any official survey — but the shape was unmistakable. A crater, buried beneath the methane swamp, and inside it, a geometric structure: perfect circles within perfect circles, connected by straight lines that spoke of engineering intent.

"The crater district," Jax said, his eyes widening. "Ashcroft, that's—"

"Exactly what it looks like," Ashcroft said. "A place that was built before anyone on this planet was born. By people who are not in the Federation's history books."

Elias took the slate. He traced the geometric lines with his finger. Something ancient. Something intentional. Something that existed before the Federation's official narrative had its first word.

"If the Federation finds out about this—" Jax began.

"The Federation already knows about it," Elias said. The words came out before he could stop them, and he immediately regretted the impulse.

Jax went very still. "You know?"

"I suspected." Elias looked at the map, then at Jax, then at Ashcroft. "When they sent me here, I thought it was exile. It wasn't. It was assignment. The Federation wanted someone who would find this and report it — or not find it and stay quiet. I was the bet they placed on their own version of the story."

The methane fog pressed against the dome like a living thing. Below them, Bayou-7 breathed its slow, chemical breath. And inside the dome, three people stood around a map to the past that the future was very determined to forget.

"We go tomorrow," Elias said. "We follow that map to the crater. And we see what's down there."

Jax nodded immediately. He was a scavenger; the word "unexplored" was his native language.

Ashcroft studied Elias's face for a long moment. "You understand what you're looking for?" he asked.

"I understand that history is not what the powerful say it is," Elias said. "And I'm going to find the part they left out."

Ashcroft shook his head slowly. "You're looking for the wrong thing, Commander. You're looking for what was erased. You should be looking for what was hidden on purpose — not by the Federation, but by whoever built that structure. Because if someone took the trouble to hide something for this long, it's not because they were afraid of being found. It's because they were afraid of being understood."

Elias filed this away. It was the sort of thing that would take him years to understand, and even then he was not sure he would.

That night, he lay in his quarters and stared at the ceiling while the station hummed around him — the sound of a machine that was slowly, patiently, falling apart. He thought about the Federation's official history, the way it flowed like a river: clean, straight, purposeful, reaching the ocean without once deviating from its planned course. He thought about the gaps in the riverbed, the places where the water had been diverted underground, and he thought about the people who had built the diversion.

Sleep came with the image of a geometric structure beneath a methane swamp, glowing faintly in the dark, waiting.
