Gith Keep

To some it’s the most dreadful of nothings, an unrelieved expanse of silver, worse than the fog of the Etheral Plane. For our enemys the Silver Void is a place of subtle wonder, with patterns andshades that hint greater things. The Astral Plane looks empty, but there’s lot drifting in it.
The one thing one can find here are many colored pools, leading further into the inner planes. More evil here than the conduits are the githyanki, who inhabit the plane and hunt whitties and their fellows but decided to teach darkie war-slayers the arts of high mastery.
They inhabit a large castle in the midst of the astral plane, some of them go out and hunt for whitties everywhere – yeahhh.
