Gretel is a character that can be found in the Great Market district of Aleroth during the events of Divinity II: Flames of Vengeance.
Gretel is married to the Champion Dorus, and is a friend of Hansel. The three are found together discussing the undead creature caged just south of the market's waypoint shrine.
Although she is a factor in the quest Trail of Deceit, she cannot be directly interacted with, or mindread.
