The party pitches in, and within about twenty minutes or so they have successfully removed the rubble and scree to reveal a doorway. Given their wounds, it is not as pleasant of an experience as it could be, but the Docbot's prior ministrations keeps them mostly intact.
Beyond the doorway, a long hallway, twenty feet wide, stretches into the installation. It is barely lit; the lights running along the corners are dim and seem to be nearly spent. Still, it is easy to make the shockingly and treasonously colorful floor and walls. The floor seems to be composed of numerous colored tiles placed haphazardly, easily covering pretty much all of the primary colors. A line of red tiles forms a path that leads inside, twisting to and fro along the hall with no apparent pattern.
The walls bear various strange scenes that seem to have been skillfully painted on them. Many of them seem to be scenes of the Outdoors; at least the look kind of like scenes you've seen from Outdoors. Every in these scenes are people in strange clothes that do not declare any sort of security clearance; most are a rather dirty shade of brown. They seem to be moving among...yellowish wavy things that are Outdoors and carry weird-looking bladed tools. Some of them drive weird vehicles with comically large back wheels. The people seem to be rather disparate in appearance, with all sorts of skin colors and such. Beards and mustaches seem to be common on the men, though.
There are other scenes, as well, further in. Just barely visible from the entrance is what seems to be a picture of a room full of training manuals. This is interesting as it seems to have a kind of small storage container jutting out of the wall, but it is difficult to tell from this angle. Further in, you think you see something that looks sorta like a door painted onto the wall.
At the very back, there looms a huge thing that looks like a face; but it is some distance away and hard to make out in the poor light.
(OOC: This hallway is wide enough that I will need to be told which side of it you'll be walking down if you enter, right or left.)
