Go'ama Phara: God of forgetfulness and revelations. He is typically depicted as a cloaked individual lost in thought as if trying to remember something. In his left hand he holds narcotic plant that when chewed makes one forget.
Go'ama Phara is typically followed in desert regions by small groups of semi nomadic people. It is said that these followers have a base of operations located deep within a desert although no one has ever verified these claims. Followers of Go'ama Phara often consume the plant there god holds. By doing so it evokes a state of amnesia. The user doesn't recall who they are, or any memory they might have had, with the exception that they consumed the plant in a ritual setting . Once in this state of forgetfulness the user then seeks to communicate with Go'ama Phara to gain hidden knowledge. The catch being that once the effects of the plant wears off they will forget what they have learned as their old memories come flooding back. To combat this followers often have a scribe or close friend sit with them and record what the user says.
Shrines to Go'ama Phara are very rare given the nature of worship among his followers. But trinkets, and charms dedicated to the god are common place among people on the edges of civilization.
The plant used in ritual isn't cultivated, and is found in the wild in arid environments. Typically on the side of craggy cliffs. Trade and recreational use of this plant is looked down upon by the followers of Go'ama Phara since they consider it sacred. Outside of followers of this religion the plant is virtually unknown.
It all depends. I'd rather have a 'deep' dungeon that was more detailed. A five level pirate king dungeon would be ideal. First level would be a cave with access to the sea, and a couple buildings and boats. Second level would be inside a stone keep of sorts. Third level would be natural caves with prehistoric wall paintings. Fourth level would be really old ruins. Final level would have lava and treasures laying around and a pirate king. Either living, undead, non-human whatever. Something like that I suppose.
