Pallid

A nameless narrator decides to move into their father's old place after he dies and run it, and their life, into the ground. But when they find a self portrait of their grandmother in the basement, things spiral out of control. Realizing the painting has teeth, and pays out cash for every blood sacrifice it consumes, the narrator's life slowly devolves into maniacal madness, with each sacrifice being made more gruesome than the last.
