This is a map of one of the sections of the first level of the Dungeon Below. It is accessible from the Tombs in the Southern Ruins. In writing up room descriptions, I have kept things to a minimum in order to allow more freedom and creativity on the part of anyone wishing to use this material. As such, I have followed Moldvay's suggestions on stocking a dungeon. Prior to the room descriptions are encounter tables. These can be used to stock this level and as wondering monster tables.
