Reactor Core Shaft — Main Engineering

A vertical, industrial artery plunging through Main Engineering, the reactor core shaft throbs with heat, ionized hum, and the scent of ozone. Grated rims and maintenance lip panels puncture the cylinder of containment; service ladders and access hatches angle into shadowed recesses where Jefferies tubes branch like veins. Light from diagnostic consoles spills up the shaft in thin bands while metal echoes betray any climb or fall. Functioning as both vital infrastructure and an improvisational route, the shaft becomes a tactical vulnerability when an intruder scales its face to reach hidden maintenance conduits, turning the ship's power heart into a hunting ground.
