Xivkyn are an intelligent race of Daedra who were created by (and swear fealty to) the Daedric Prince Molag Bal. They were created to serve as his personal guard, and are the product of experiments with vestigial hybridization between Dremora  (or "Kyn") and Xivilai in the Vile Laboratory. They are fiercely loyal to Molag Bal, and were in charge of the Daedric occupation of the Imperial City during the Planemeld.

Xivkyn are known to train Clannfear and Daedroths, and consider harvesters to be lacking in cunning. The term "Xivkyn" is heavily Cyrodilicized, referencing the Xivkyn's resemblance to the Dremora and Xivilai the race was "bred" from. They have several names for themselves, including the terms Stolavryk, Khimrykif, and Vyrsago. How the Xivkyn refer to themselves seems somewhat sporadic, as what they call themselves is said to "change depending on the hour".

They appear as tall humanoid Daedra that possess blue-grey skin and ridged black horns that vary in length and curvature. Apart from the standard rack of horns, they may also have smaller horns on their forehead, crown, or chin. They also have sunken, icy blue eyes resembling their master's, as well as tapered ears. They tend to tower over their Dremora subordinates.

Xivkyn are known to adhere to a strict uniform code, with guidelines laid out in accordance with the will of Molag Bal. Their weapons and armor are practical, but reflect the fearsome image Molag Bal would like a powerful servant of his to present. They are often fully covered in armor, leaving only their glowing eyes visible, instilling a fear of the unknown in mortals.
