Ammut

Ammut lived near the scales of justice in Duat, the Egyptian underworld. In the Hall of Two Truths, Anubis weighed the heart of a person against Ma'at, the goddess of truth, who was sometimes depicted symbolically as an ostrich feather. If the heart was judged to be not pure, Ammit would devour it, and the person undergoing judgement was not allowed to continue their voyage towards Osiris and immortality. Once Ammut swallowed the heart, the soul was believed to become restless forever; this was called "to die a second time".
