The compound itself was a massive circle; the walls were about fifteen feet high, surrounding the entire area, but they were mostly for show; the actual defenses were a wall of magic spells designed to keep most things from getting in or out, just a few feet inside the anti-teleport aura. He'll note that, among the defenses, walls of force are designed to spring up, if anything tries to get out, and gets past most of the other protections, although nothing's set to trigger if it's heading into the compound. Nine different 'buildings' ring the camp; he can make out writings on them that indicate what each one is; prison, torture, slaves, toys, breeding, pets (less likely to refer to captives, and more to 'special' demons used for their amusement), food, incoming, outgoing. There's a large open plaza in the middle, with a gladiatorial ring at its heart; at the moment, there seems to be a 'match' going on, as seven elves, armed with simple weapons and dressed in extremely revealing armor, are being pitted against a rather unusual-looking hydra monster; instead of heads, it has seven tentacles, coming out of its body, and, as he watches, one is cut off, only for two more to grow. The demons surrounding the ring cheer, as one of the elves is grabbed, and three tentacles work together to start stripping her.
