Iolcus

Jason was the son of Aeson, the rightful king of Iolcus, and Alcimede.

Jason learned that he was the rightful heir to the throne of Iolcus, currently held by the usurper Pelias.

When Jason arrived in Iolcus, he confronted Pelias.

Upon their return to Iolcus, Jason presented the Golden Fleece to Pelias.

Jason did not take the throne of Iolcus; instead, he and Medea fled to Corinth, where their story would take a darker turn, ultimately leading to Jason's tragic end.
