Tu'narath
In the Dungeons & Dragons role-playing game, Tu'narath is the capital city of the githyanki, a race of humanoids descended from slaves who overthrew the illithid empire thousands of years ago. The city is located on the Astral Plane, where it was built atop a god-isle, the corpse of a forgotten god known only as The One in the Void. At the centre of the city is Susurrus, the palace of the githyanki queen Vlaakith CLVII.
