The Sun We Pay For

The lamp is the vault's only sun, and every stalk in Ceres leans toward it.

An artistic imagining, not real hardware. A square print on pale stock, drawn in scratchy broken ink strokes over blue halftone dot screens that sit slightly out of register with the drawing. The scene is the inside of a rounded chamber cut into rock: a crosshatched rock ceiling arches across the top of the frame and down both sides, and a narrow bored shaft enters at the top left, carrying one vermillion cable down to a small vermillion switchboard bolted under the crown. A horizontal lamp gantry hangs from the ceiling high and left of centre, slung with six angled luminaires whose mouths are left as bare paper with a hot filament line across each. From them a fan of pale light cones spreads down and outward across the chamber. Five curved growing terraces stand in concentric ranks around the lamps, each a shelf with a ribbed substrate skirt hung beneath it, and each rank carries a row of mushrooms whose domed caps and gill ticks face inward, so every stalk in the vault leans toward the lamps. The mushrooms grow larger toward the front of the frame, where several reach the height of a person. Two vermillion service risers run outward from the lamp hub across the terraces, tapping each rank at a small junction box, and short vermillion dashes run along the inner rails as heating elements; a thin hoop of misting nozzles crosses the middle distance with faint plumes. Four faceless suited workers are at work in silhouette: one at the lower left holding a pale tray of cut caps, one at the centre reaching up to a cap, one small figure on the far right, and one pushing a cart near the lamps. Stacked crates of cut mushrooms sit at the front. No text, no insignia, no lettering. Nothing shown here exists.
An artistic imagining, rendered procedurally, of a mushroom vault cut into Ceres: five curved terraces of fungus ranked around one hanging bank of lamps, with the whole crop leaning inward toward the only light in the world, and the power arriving on a single cable down a bored shaft to be spent on light, heat and damp. Mushrooms really are grown in the dark on substrate rather than by photosynthesis, and blue light acts on them as a cue rather than as food, triggering fruiting and pulling the stalks toward the lamp, while most of a mushroom house's energy goes on heat, humidity and air; Ceres is genuinely ice rich, but these vaults are speculation.
