Amedala

Amedala is a continent of near geometric perfection found to the far northeast of Nexus. Whatever once lived there is long gone, owing to the unwanted invasion from Gith and Illithid. This was thousands of years ago, caused by a Githyanki collapsing the area of the astral sea onto the material world, bringing a full fleet of Githyanki, a migrating Githzerai Monastery, and an Illithid stronghold onto the continent. It has since been shaped by their violence and psionic practices.

Over the course of history, the Illithid have been driven into the Underdark, the continent has been blasted open, causing the former surface to become a great series of floating islands, and the former "Upper" Underdark to become the surface, with the Illithid then thrown even further down, the Gith now occupying their strange contraptions of cities and strongholds.

Politically, Amedala is split into many competing Ideologies, which all mingle together. There are no hard borders on Amedala, in this political frame, and instead Gith subscribe to a wide variety of factions, all operating independently and together at once.
