Five... or perhaps four people have arrived here for reasons unknown. They wander aimlessly through this dark and eerie place, searching for a door that will lead to the next area.

Small amounts of food and supplies can be found in each location, preventing them from starving. However, that isn't the real problem.

Monsters. There is at least one in every location. While a few are harmless, they are a tiny minority; almost all are aggressive. Since most encounters leave no survivors, they must move as quietly as possible. Whether an exit truly exists is unknown, but for now, they must keep walking.
