The Moon · Survey

Not a moon.
A machine wearing one.

From orbit, Selentara is grey rock and craters. Under 400 metres of shell it is hollow — and the hollow is full.

Survey · Section A–A
01 · Cross-section

Ninety-six levels. True proportion.

Every line below is a real inner level, drawn from the same geometry the game builds them from. They are stacked 160 metres apart, straight through the body — small discs near the poles, sixteen-kilometre worlds across the equator. Hover any of them.

No one has mapped a way onto this level yet. Most of the moon is still like this.

The surface is only the outside.

Survey · Shell
02 · The shell

Five layers between you and the inside.

The skin is regolith. Everything under it was engineered — to take impacts, spread them, listen, and hold the levels up.

L1Impact Shell0–60 mAblative regolith skin. Takes the meteor flux so nothing below has to.
L2Reinforced Composite60–80 mThe first engineered layer. Where the moon stops pretending to be rock.
L3Dissipation Grid80–140 mSpreads impact energy around the sphere before it can punch through.
L4Sensor Array140–220 mStill listening. Nobody alive knows what for.
L5Structural Ring220–300 mThe load path. Every deck below hangs from it.

03 · Two worlds

Outside and inside play like different games.

The surface is exposure and distance. The levels are corridors and close calls. Every run crosses from one to the other — usually more than once.
