I drew my mind for a contest on deviantart...
(I can't copy and paste on this computer so I'll put the link up later, but for now its in my art thread.)
Thats only part of it, and yeah. That half is the half above ground. The other half, which I didn't draw, would be underground and dark. A bunch of tunnels in a maze, that lead to a large red window. (it's from a nightmare I've had o_o)
