# Chapter 4: Oil Lamps Under Another Sun

**20 years, 011 days until keyhole crossing**

Earth-2 filled the forward glass like a memory no one aboard had earned.

Blue ocean. White weather. Brown continents under green veils. A moon scarred silver in the distance. For a foolish second, Mira's body accepted the lie of familiarity before training corrected it. The coastlines were wrong. The storms turned over different seas. The polar caps held unfamiliar shapes. The cloud shadows crossed nations whose names no one from Earth had a right to know yet.

Behind her, the command deck had gone silent.

Even Hana Sayegh stopped moving.

The rescue ship Argo had spent twenty-one months falling between stars inside a machine that made distance feel bureaucratic: injection burn, cruise rotation, systems watch, medical cycles, simulation, sleep, wake, message packet, grief, another burn. The human mind could not hold interstellar travel as an experience. It reduced the impossible to schedules and alarms. Then a planet appeared in the window and every abstraction failed at once.

Jonas stood at the engineering station with one hand braced against the console. He looked older than when they had left Earth. Not by much. Enough. There were new lines at the corners of his mouth from holding back things he did not want the crew to inherit.

"Approach velocity nominal," Flight Officer Rhee said.

Her voice steadied the room because someone had remembered to be professional.

"Thermal signature pass," Mira said.

The main display split into layers. Daylight vanished into instrument sight. Night rolled under them.

There they were.

Not cities in the Earth sense. Not grids. Not the electric lace of continents seen from orbit. Earth-2's night was mostly dark, a deep old dark that Earth had forgotten how to make. But along rivers and ports and mountain bowls, warmth gathered in deliberate clusters. Thousands of lamps. Kilns like coals. Forge districts. Beacon towers. Processions. Fishing fleets strung as faint amber beads along black coasts.

Oil, wood, charcoal, whale-fat analogues, plant resins, whatever local chemistry had taught them to burn.

Civilization whispering instead of shouting.

"My God," Rhee said.

Taren Pell, strapped into the cultural station, whispered, "Which one?"

No one laughed, but the comment released enough pressure for people to breathe again.

Mira watched the largest river basin rotate into view. The city from the time-lapse was there, its lamps concentrated around a forked waterway. The mission had named it RB-1 because scientists could be trusted to turn wonder into filing systems. Taren had forbidden anyone to use that aloud once contact began.

"Passive only," Mira said. "No active radar over population centers until we finish the contamination review."

Hana glanced at her. "At this distance?"

"At any distance."

Hana looked as if she might argue, then remembered Chapter One of Mira's command conditions and returned to her models.

The ship slipped across the terminator into dawn.

Earth-2's sun rose over a mountain chain like fire poured through teeth. Valleys sharpened. Rivers flashed. Agricultural terraces spread across hillsides in green and gold steps. Roads connected walled towns. Smoke rose from morning hearths in columns too small to be weather. In one coastal city, hundreds of triangular sails moved out through a breakwater, catching first light.

Jonas touched the glass with two fingers.

"Elian would say it needs a dragon room."

Mira kept her eyes forward. "She would."

Their last received packet from Earth was nine months old. Elian, six now by the calendar but five in the message, had lost a front tooth and refused to show them until the final three seconds, when she lunged at the camera and made a face. Mira had watched those three seconds twenty-seven times. She had not told Jonas the number. Jonas probably knew.

"High-resolution pass over observatory candidate," Taren said.

The display shifted to a dry plateau above the river civilization. A stepped stone complex sat on the ridge, aligned with horizon markers and shadow channels. Towers with lens housings. Courtyards engraved in geometric patterns. People in pale robes moved like chalk marks across the morning stone.

"Optical astronomy," Taren said. "Advanced. Look at the meridian slots. This is not astrology as decoration. They measure."

Hana leaned forward despite herself. "Can they see E2-X1?"

"Not yet," Taren said. "Not with naked eye. Maybe through their best lenses in a few years if they know where to look."

"They won't know where to look."

"No," Taren said. "They won't."

The room lost its fragile wonder.

Mira brought up the mission timeline. Twenty years until keyhole. Less than nine for the first local heavy-lift chain, if Hana's revised model held. They had arrived on schedule and still felt late.

"Begin language capture," she said.

Taren's team activated the passive listening net.

At first the ship caught only weather noise, electrical static from the planet's own moods, lightning murmurs, auroral hiss. Then the acoustic satellites dropped toward upper atmosphere and began collecting open-air sound from selected sites, narrow as needles, legal under a contact protocol written by people who had never been desperate.

Earth-2 spoke.

Not one language. Dozens in the first hour. Tonal river speech. Harsh mountain consonants. Coastal trade pidgins. Temple chants. Market calls. Children shouting over animals. Bells. Drums. A woman singing while grinding grain on a roof. A man cursing a broken cart axle with such elaborate rhythm that the translation AI tagged it as possible poetry.

The crew listened like thieves outside a family home.

Taren removed his headset.

"We have to name the ethical breach," he said.

"Noted," Mira said.

"Not just noted. Named. We are listening without consent."

"We are."

"And continuing."

"We are."

He looked at her across the deck, grief and accusation mixed. "The first compromise."

"No," Mira said. "Not the first."

That quieted him because everyone aboard knew the first compromise had been departure.

Hours later, as Argo passed over the night side again, the Suryan observatory saw them.

The observer's name was Leth Aru, third lens-keeper of the Western Meridian Tower, and he had been awake for thirty-one hours because the queen's calendar commission wanted the red comet's updated position before flood season rites. His left eye watered constantly from lens strain. His apprentice had fallen asleep against a stack of wax tablets. The tower smelled of lamp oil, cold stone, and the bitter tea scholars drank when youth failed them.

Leth was not looking for gods.

This mattered later, when priests accused him of arrogance and generals accused him of panic. He was not looking for omens, either, though the tower kept omen books because donors liked them and because even honest astronomers had to eat. He was measuring the red comet's drift against the old Meridian Table and composing, in the privacy of his tired mind, an insult against the dead men who had copied last century's numbers so badly.

Then a star crossed the lens.

Leth blinked.

Stars did not cross the lens. Clouds did. Birds did. High ash did. Once, during a winter fever, he had seen his dead mother cross the lens and wisely told no one. But this was a white point moving with clean purpose across a section of sky where no lamp, comet, or planet had permission to move.

He adjusted focus. The point sharpened.

Not fire. Not falling. Not a meteor.

It brightened, dimmed, vanished behind the edge shadow, and returned where calculation said it should not.

Leth's mouth went dry.

"Sira," he said.

The apprentice did not wake.

"Sira."

She snorted and jerked upright, leaving a smear of ink on her cheek. "I was copying."

"You were dreaming of copying. Bring the fast slate."

"Master?"

"Bring it."

He tracked the impossible point by hand, whispering angles while Sira scratched numbers with increasing panic. The moving star crossed the southern measure, passed above the broken tooth of Mount Avel, and disappeared into dawn glow.

Leth stood frozen with one hand on the lens wheel.

Sira looked from the slate to the sky. "What was it?"

A cautious scholar would have said artifact. A religious man might have said messenger. A courtier would have asked what answer was safest.

Leth was old enough to have lost patience with safety and young enough to still love truth more than his position.

"Something that climbs while falling," he said.

"That is impossible."

"Yes."

"Should I wake the tower master?"

Leth thought of the queen's commission, the flood rites, the argument between the temple college and the canal guild over calendar drift. He thought of the old story of the Black Shepherd, the dark guide that returned beyond sight when kingdoms forgot humility. He had never believed it literally. Most astronomers did not, though they allowed priests to think otherwise for the peace of dinner tables.

Now an impossible star had crossed the queen's sky.

"Wake everyone," he said.

By noon, the Western Meridian Tower had confirmed the sighting with two smaller observatories. By dusk, a sealed rider carried Leth's slate copies down the ridge road toward the capital. By midnight, three temple colleges were arguing whether a star could be artificial without being divine. By the next dawn, Queen Aravel Nara-Suryan had ordered the lens records brought to her private study under guard.

Argo watched all of it through instruments no Suryan eye could see.

Taren mapped the courier routes with growing unease. "They are fast."

"Good," Hana said.

"Fast belief and fast fear use the same roads."

Mira stood behind them, arms folded. On the display, the rider descended through switchbacks lit by torch stations. A single human on a sweating animal carrying evidence that the universe had broken.

"Can we prevent panic?" Rhee asked.

Taren laughed softly. "Captain, we are panic."

Mira did not answer. She watched the courier until cloud covered the road.

In her private cabin, after the shift ended, she opened Elian's archived departure video. Not the latest packet. The old one. Elian at five, dragon in hand, face solemn with borrowed bravery.

"People on the other planet," the child said, "you can borrow them. But not forever."

Mira paused the video on her daughter's face.

Outside the hull, oil lamps moved under another sun. Inside, the mission clock counted down with mathematical indifference.

They had arrived.

Now they had to become real.
