Like all Daemon Princes Charon was once a mortal. He was born on Prospero itself sometime before the Emperor arrived to claim his son. His psychic power was recognised by the Thousend Sons and he was selected to undergo the transformation into an Astartes (Charon claims that his selection was by Magnus himself). The transformation complete Charon joined the Legion's Raptora Cult and eventully rose to join the Librarium itself. It was known that he had a twin brother who too joined the Legion's Raptora cult and became a Librarian, it is believed that he refused to swear alliegence to Tzeentch and was killed as a result
