The Early Years
Jason was the son of the lawful king of Iolcus, but his uncle Pelias had usurped the throne. Pelias lived in constant fear of losing what he had taken so unjustly. He kept Jason's father a prisoner and would certainly have murdered Jason at birth. But Jason's mother deceived Pelias by mourning as if Jason had died. Meanwhile the infant was bundled off to the wilderness cave of Chiron the Centaur. Chiron tutored Jason in the lore of plants, the hunt and the civilized arts. When he had come of age, Jason set out like a proper hero to claim his rightful throne.

When Jason arrived in Iolcus, he asserted his claim to the throne. But his uncle Pelias had no intention of giving it up, particularly to a one-shoed stranger.
The Challenge
Under the guise of hospitality, he invited Jason to a
