Clavicus Vile's Masque

Ever the vain one, Clavicus Vile made a masque suited to his own personality. The bearer of the masque is more likely to get a positive response from the people of Tamriel. The higher his personality, the larger the bonus. The best known story of the masque tells the tale of Avalea, a noblewoman of some renown. As a young girl, she was grossly disfigured by a spiteful servant. Avalea made a dark deal with Clavicus Vile and received the masque in return. Though the masque did not change her looks, suddenly she had the respect and admiration of everyone. A year and a day after her marriage to a well connected baron, Clavicus reclaimed his masque. Although pregnant with his child, Avalea was banished from the baron's household. Twenty one years and one day later, Avalea's daughter claimed her vengeance by slaying the baron.

The masque was owned by the Hero of Daggerfall as well, sometime around the year 3E 410. Obviously after dealing with Clavicus Vile. The Prince asked the hero to slay a certain werewolf. After the deed was done, the hero was rewarded with the masque.
