Rejkars are large, powerful stag-like creatures native to Baator. They have thick white fur, black antlers, and are about 8 feet long and 6 feet tall at the shoulder, weighing around 2,000 pounds. Originally from Cania, the frigid layer of Baator, they despise the baatezu and often migrate to the arctic regions of other planes to establish their own territories. Rejkars use their magical abilities to manipulate and control the leaders of arctic tribes, offering aid and visions to gain their trust. They then extend their influence through the tribe, aiming to dominate and expand their power bases.

In combat, rejkars employ their freezing gaze to immobilize foes and rely on their minions for direct confrontation. They can also use various spell-like abilities such as crushing despair and fabricate. Rejkars are immune to cold but vulnerable to fire, and they possess darkvision and other outsider traits​
