The Shape of the Hymn

Kaelen caught the terminal before it slid off the shrine ledge.

Its casing struck the stone with a hard click. He froze, one hand wrapped around it, while the sound traveled through the buried chamber and died among the ribs of the machine. Above him, footsteps crossed the shrine entrance.

He killed the screen and shoved the terminal beneath his work cloth. A strip of blue light still showed at the altar’s base. Kaelen stepped between it and the entrance, his oil bowl held out as if he had been interrupted in the middle of his duties.

Elder Orr descended the steps alone.

“You’re late with the lamps,” he said.

“I’m finishing the lower channel.”

Orr’s eyes moved over the cloth, the ledge, the unlit lamps. He did not ask what Kaelen had been doing. “Finish before dawn. The chosen household will come early.”

Kaelen lowered his gaze. “Yes, Elder.”

Orr watched him another moment, then turned back up the steps. Kaelen waited until the last footfall had passed before he let his fingers loosen around the bowl.

He had no more than an hour. Perhaps less.

The terminal’s old battery was nearly spent. He connected it to the exposed service port again, careful to keep the cable from scraping against the metal. The screen flickered. The maintenance record remained where he had left it, with the converter’s name and the word STANDBY.

Below it, a narrow line of text had appeared during the interruption. Kaelen had glimpsed it just before Orr came down.

AUDIO INDEX: OPERATOR COMMANDS.

He pressed the selection key.

A list filled the screen. Most entries were damaged. One held a length of sound, marked with a date he could not read and a status he could: VERIFIED.

Kaelen put the terminal’s speaker close to his ear.

A woman’s voice came through, thin with static. “Ares-VII service archive. Command profile accepted. Intake mode active.”

The voice was as flat as the one that had named the converter. No priestly cadence, no warmth. The next words came in clipped pieces.

“Biomass Energy Converter. Organic input required. Processing will generate electrical and chemical reserves. Residual matter will be routed to waste storage.”

Kaelen stopped the recording.

For a moment he heard only the soft scrape of his sleeve against the terminal. Then his hand moved back to the keys. He replayed the line once, then again. The words did not change.
