The Entrance from Erinn may be reached by dropping a Black Fomor Pass on the altar of Barri Dungeon. It can be found after the Boss Room, where the reward room normally is. It is guarded by a gate that may only be opened by the person who dropped the pass.
The other entrance may be reached by asking Dougal in Tir Na Nog to return to Erinn.
- Although the map says Tir Na Nog and Barri Dungeon, the entrances say Another World and Erinn, respectively.
