The tunnel that led upwards was just as gloomy as the one below, with only the thinnest tube of glowing yellow fluid lighting Kothar's way.
The rungs made of the same gray material as the rest of the ship, and just like the walls, were warm under Kothar's hands.
As he climbed, Kothar could feel the spatial fluctuations growing stronger and stronger, the Spatial Necklace almost pulling him towards the source of the fluctuations.
Kothar climbed continuously for almost half an hour, passing by tunnels similar to the one he had entered the vertical shaft from, running horizontally through the vertical tunnel.
All through these tunnels, the thick pipes ran, connecting with each others and occasionally turning off and disappearing into the walls.
