Xivilai are highly intelligent Daedra that look like tall and muscular gray-skinned warriors. They are similar in many points to the Dremora, but do not have a caste system. Their lack of a caste system fits perfectly with their hatred of subordination and tendency for betrayal. They are also often in the service of Mehrunes Dagon. They can wield two-handed weapons in one hand and cast a wide variety of spells, including a Clannfear Summon.
Xivkyn are powerful humanoid Daedra created by Molag Bal. They are a fusion of Dremora ("Kyn") and Xivilai, and are the result of Bal's experiments with vestigial hybridization in the Vile Laboratory. They were in charge of the Daedric occupation of the Imperial City in 2E 582.
