Azura

Azura is the daedric prince of dusk and dawn, and one of the few not considered to be inherently evil. The Khajiit have "Azurah", the Goddess of Dusk and Dawn and sister of Nirni.

One mighty known artifact of Azura is Azura's Star, which is a reusable, Grand Soul Gem. It already played a role in the previous installments of the game series. In The Elder Scrolls V: Skyrim, the player even could travel (with Azura's help) into the star itself to cleanse it from the influence of a mad mage.
