Jason, on a quest for glory and legitimacy, seeks the fleece to reclaim his rightful throne, while Pelias, his uncle, fears losing power and tries to thwart Jason's ambitions. The myth emphasizes themes of heroism, ambition, and the struggles between family loyalty and personal aspiration, ultimately defining the journey of the Argonauts in pursuit of their quest.
