From the introduction: Warning: This is a meat-grinder if the party isn't largely immune to Ghoul's Touch. Reduce the difficulty by using a rescue-the-prisoners scenario or substituting zombies. It is cool and dank down here. Throughout the shrine there are torch sconces in the walls, but no torches. The floor is covered with cracked faded tiles; it is impossible to make out the original pattern, but it is still somehow vaguely disturbing.
