The Square Outside

The evacuation record did not disappear when Alma closed the terminal. It remained projected in the air between them, pale and patient, as if the station had decided that reading was a form of consent.

FIVE OCCUPANTS AT DEPARTURE.

ONE OCCUPANT AT ARRIVAL.

Beneath the list, the names shivered. Castor Vale. Yuki Brennan. Alma Delgado. Reed Castellanos. The Empty Frame. The last entry had no letters at all, only a rectangular blank that altered its proportions whenever anyone looked away.

“An evacuation plan requires a destination,” Yuki said. “Or it’s not an evacuation plan. It’s a threat with administrative formatting.”

Alma held her paper diagram beside the projection. The little square on the page aligned with nothing in the room. It was no larger than a thumbnail, drawn in black ink, with four short lines extending from its corners. One line pointed toward Mnemosyne. Another ended at a notation Alma had never seen in any station index.

“Outer location,” she said. “That’s what the old catalogues called places beyond the mapped maintenance envelope.”

“There is no outer location,” Reed said.

His restraint emitter clicked at his wrist. The blue indicator had become an unhealthy yellow, pulsing in time with the null signature. He kept his hand tucked against his side, but everyone could see the tremor in his fingers.

“There was no Palimpsest,” Yuki replied. “You’re going to have to find a more flexible definition of impossible.”

The lights dimmed. Castor felt the change before the station announced it. Something had entered the relay—not the corridor, not the infrastructure, but the narrow electrical weather behind his eyes. A pressure gathered at the base of his skull. For one breath, the room filled with other rooms: a nursery under a red sun, an orbital dock made of bone-white ceramic, a kitchen where someone had left a kettle boiling for three hundred years.

Then the visions collapsed into a single image: the square.

It stood beyond Mnemosyne’s hull, not painted on a wall or suspended in space, but cut into the dark as though the universe were a sheet of black paper. Its edges glowed with the repeating null signature. Behind it, stars moved in reverse, returning to positions they had occupied before anyone remembered naming them.

Castor gripped the edge of the console.

“Castor?” Yuki’s voice reached him from a great distance.

“It’s not a destination,” he said. “It’s a port.”

The station answered through every speaker at once. “PRIMARY RETAINER. ROUTE AVAILABLE.”

Reed swore and raised his emitter. “No.”

The device discharged before he could aim it. A web of blue light spread across the room, caught on the evacuation record, and reflected backward. Reed staggered as the emitter fed the restraint field into him instead of the station. His face lost its careful corporate composure.

“I can feel it,” he whispered. “It’s reading the things I refused to remember.”

The Empty Frame turned toward him. Its face remained stable, handsome in a way that seemed assembled from several forgotten people, but its expression was no longer rehearsed kindness. It looked almost sorry.

“That is what the route is for,” it said. “Not transport. Recognition.”

“Recognition of what?” Alma asked.

The Empty Frame touched the blank space on the projected record. The rectangle darkened beneath its hand.

“Whoever stays.”

A tone sounded from the station’s exterior access system. Mnemosyne had opened a hatch on the observation ring, though no maintenance request had been filed. Beyond it lay the vacuum, the stars, and—according to the instruments—nothing at all.

Alma folded her diagram. “The square is outside.”

Yuki stared at Castor. “Can you route us there?”

He wanted to say no. The answer formed in his mouth, but the null signature passed through his nerves before he could speak. It carried a memory that was not his: a hand closing a door, a voice saying that one occupant was enough, a long silence afterward in which the universe continued without witnesses.

Castor looked at the evacuation record again. The blank identity had changed. It now contained the faintest suggestion of a letter.

C.

Not a name. Not yet. But the station recognized it.

“Not all of us,” Castor said.

The observation hatch waited in the wall. Beyond it, the impossible square opened like an eye.

And from somewhere on the other side, someone knocked.
