What I posted for Rhaezon earlier
Inside the Dome: The air is cool and moist, and somehow there are thriving green potted plants giving the whole place fresh air. Most of the interior, however, is filled by a maze of machinery. Spinning turbines, rotating dishes, and banks of control panels and interface stations. The floor is made of multicolored ceramic tiles.
There is also a panel in the side of one of the large machines that has been removed, exposing a cylindrical space where something obviously gets "plugged in" and affixed to some wires, cables, and conduits. Rhaezon has a cylinder that obviously fits into that space, along with various wires and prongs that would allow it to be connected to the larger mechanism, but just as obvious is the fact that the cylinder has burned out from the inside. It is blackened and partially melted.
