Qorrashi

Qorrash are perfectly at home in the cold, and, like Djinn, don't eat and can create huge amounts of food out of thin air. So Qorrashi settlements are pretty popular places to live, even if leaving is nigh-impossible. In Planescape canon, most Qorrashi settlements are under the surface of the ice, since the entire (two-dimensionally infinite) surface was conquered by the evil Archomental. Yes, the whole thing, and yes, that's silly. So the Qorrash live on both the surface and the depths.
