Avalea was a noblewoman of some renown.
As a young girl, she was grossly disfigured by a spiteful servant. She then made a deal with Clavicus Vile and obtained the Masque of Clavicus Vile. The mask did not change her physical appearance, but instead gave her the respect and admiration of everyone.
She married a rich baron a year and a day later. Then, Clavicus reclaimed his mask. Avalea, pregnant with child, was banished by the baron. Twenty-one years and one day later, Avalea's daughter claimed her vengeance by slaying the Baron.
