People who use OOO should understand what I am talking about. The Body and Greaves, along with the helm, come from Prince Xyval Vikyur during light the dragon fires. The guantlets and shield are gotten from the great gate, with one of them being from Two guards outside the worldbreaker main tower, and the other from 'Sigil Keepers' inside the tower. The boots from a dremora near the sigil during the first Bruma gate quest, with the guards. It can be gotten in pieces from specific dremora encountered during the course of the main quest. It is a special set of Daedric armor that is slightly better then normal daedric armor, and is also a diffrent, more orange-ish color. Let me explain Daedric Prince armor (a bad name for it, as it makes you think of the Daedric Princes). He is an Unique enemy that only appears during the light the dragon fires quest, outside the temple of the one.

This is a DREMORA named Prince Xyval Vikyur, not an Xivilani. and can be hard to understand certain small parts if you haven't played it.
