Evergloam:Nocturnal

Nocturnal.

Nocturnal who is also known as the Night Mistress, the Mistress of Shadows, The Unknowable, Empress of Murk, Daughter of Twilight, The Mistress of Mystery and The Saint of Suspicion is the "Daedric Princess" whose sphere is the night and darkness.

Nocturnal possesses several realms throughout Oblivion. One such realm, Shade Perilous was once accessible through the Battlespire, but the realm has been isolated since the Battlespire's destruction. Another is Evergloam, to which the player is summoned in the first quest.

She is often depicted wearing a dark, hooded cape. It is rumored that this cape turns into a raven when she takes it off. She doesn't wear it in her own realm, and it is likely that it protects her from sunlight, which damages her in the same way that it does a vampire.
