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 either the domained claimed by the evil Archomental Cryonax or under the control of a powerful white dragon. So the Qorrash live on both the surface and the depths.
