In the side of Merman’s Bluff beneath White Crag Fortress there is a small entrance into the rocky crag with a worked stone wharf leading into the dark choppy waters. This postern gate to White Crag Fortress is intended to be well guarded, although the original door has been removed after it got stuck too often from rusting hinges and lock as well as swollen oak from the constant battering from the sea. In time it should be replaced by a properly oiled and tarred door, but for the time being the gateway remains open.
The main level of the structures wind up under the structures of the Bailey Fort leading eventually to a trap door opening into the fort proper. These structures are used as storage, guard rooms, and an escape route in case of emergency.
There is also a passage that leads up under the Spire, however it lacks an accessway into that structure (at one point there was such an access point, but a team of mechanical assassins used it to gain access to the spire and it was blocked off afterwards). This section contains a secret chamber that in turn has a trap door down to the lower chambers which are used as a secret dungeon for prisoners as well as an underwater escape route for those with the access and the means to travel underwater.
The tunnel leading underwater from these lowest passages proceeds 130 feet further from Merman’s Bluff and into a small cave 20 feet under water.
