100 Secret and Hidden Doors and Passages to Find in a Dungeon

Secret doors, hidden passages and hard to find compartments are a staple of dungeon design, as well as for other buildings and constructions. This supplement has 100 such for characters to find. They range from the well concealed that have hidden or unusual triggers, to the more normal that are simply not visible without searching. Whether or not the hidden areas lead to passages to other parts that can be traversed, or whether they simply reveal secret compartments, is up to the GameMaster.
