Abraham is the main antagonist of the Sister II arc of El Goonish Shive. He created the Dewitchery Diamond, a magic object that splits a cursed person from his/her curse and gives the curse a new body. During the Sister arc, this happened to Elliot, creating Ellen. Abraham himself swore to destroy all the bodies created by the Diamond, and thus tries to kill Ellen. However, Adian Raven, son of Pandora, protects her. After Abraham realises that he was trying to kill an underaged girl, he gives up and leaves.
