Rappan Athuk - Mouth of Doom - First Taste
This outlying entrance to the main dungeon was built by the priests of Orcus to be used as an escape tunnel, or as a way of sneaking their troops to the surface in case the main entrance was to fall under siege. Because of the great distance between the Mouth of Doom and the central environs of the dungeon's vast catacombs, this is perhaps the least dangerous region in Rappan Athuk -- which isn't saying much, but at least the chances of survival for a low-level adventuring party are somewhat better here.
