Asclepius is a Greek God who was once a Demigod son of Apollo and the mortal woman Coronis. He is the God of Medicine, Rejuvenation, and Health. When he was mortal, he discovered the Physician's Cure, which can heal even death itself. However, he angered Hades when he used it. As such, he was killed and his father demanded that he be made a god. He was, but was imprisoned for eternity by Zeus to ensure that he wouldn't make the cure again.
