The Order of the Azure Key
A mysterious old cabin that stands on a sea cliff looking out over the ocean. It is located just south of Mistwatch. The people have Mistwatch have always known it was there but many like to pretend it is not. There are stories of strange lights and sounds that came from the cabin but those stories are now decades old.
Upon visiting the cabin it was found that the only way to enter is from a door facing the sea with no solid ground beneath it. It is inhabited from time to time by a strange old warlock. Both the cabin and the old warlock seem to have some connection to the other planes of existence. The cabin is located at a seep and acts as a bridge between the material plane and the planes beyond.
