The outside of the door is black steel, with an iron handle and an old-fashioned keyhole. It's unnaturally hot to the touch. Blood-red glowing letters across the front mark "KANE." The inside is also steel-plated, and it feels extremely hot. It's very dark, with only a dim red lighting coming from nowhere in particular. There's a simple mat for a bed, and Kane's mask is behind glass, inside the wall. The walls are dented from what looks like blunt impact, from fists.

Inside sits Kane, blankly staring at the wall, appearing very angry as usual.
