Ava, the withered hag
Appearance: frail, withered, mean woman, as old as time, constantly frowning and chewing. No one has ever seen her standing from her chair or heard her talking.
Portrayal: she just stares all day long with her judging eyes from the darkness of the inner balcony of her son's tavern, "the withered hag" (they say the tavern is named after her). No one pays attention to her, but she sure has seen everything that happens in the tavern.
Hook: for the first time in years, she has spoken! Pointing her bony finger to one of the PCs who entered the tavern for the first time, she has yelled "He is back! He is back!"
