Crystal Caves

In the far northeastern part of the East Frozen Jungle, there is a place where the deep brown soil gives way to white. For once the silvery patch is not frozen water, however, but crystal. Curious tributes who venture closer will find a hole in the ground and, through it, a complex system of caves and tunnels made from the same nearly-clear substance. Though the walls here feel and are shaped like the walls of any normal cave, their opaque quality makes them hard to navigate. Anything inside the tunnels can be seen from adjacent ones—not clearly, but the dim, distorted shapes are enough to both warn and unnerve anyone. This effect lessens as one descends into the ground and the sunlight diffuses, but in the deepest tunnels an entirely new effect arises: any light created with fire or electricity will bounce around the tunnel it's carried through, amplifying the brightness considerably. As strange as this all it, there is little danger to any of it. Indeed, being able to see clearly makes it much easier to find one's way out—not to mention safer, since it's almost impossible to sneak up on anyone. Of course, it's equally hard to hide from anyone, so perhaps there are better places to stay after all.
