The cowl of the Daedric Prince Nocturnal is the reason for his alleged disappearance. The magic within the cloth hid his identity from everyone, including his own wife, Countess Millona Umbranox. The cowl became cursed when Emer Dareloth stole it from Nocturnal, becoming the first Gray Fox. As a result, whoever wears the cowl will have their name stricken from history.
