Her current guise is as a nun under the name Agatha Gloomfoil. She is one of the primary antagonists of the game. Double is an enigmatic character who lacks a distinct motive or will that most of the cast have and rarely emotes. She mostly maintains a stoic, calm demeanor but is prone to moments of rage.
