Midden of the Deep

Midden of the Deep is the third one-page adventure location.  Suitable for adding spice (or ammonia - eww) to any huge cavern that might once have held dragons (or other, magical, excreting creature).

Like its bretheren, Midden is systemless, but easily adaptable to crawly games like D&D, Torchbearer, Dungeon World and World of Dungeons.
