Marcus of Argos

Marcus became the royal regent of Argos after Jason's depression and alcoholism made him an unsuitable king. He was a devout Hera worshipper and was affiliated with the Blood-Eye Cult of which Castor was the leader. Marcus worked with Castor to discredit Jason by stealing the Golden Fleece. Instead, the Argonauts rallied behind Jason for a second expedition to retrieve the Fleece. Marcus was given a bag of bones by Hera which, when released, turned into her Skeleton Warriors. Marcus released the warriors to fight the Argonauts and he was accidentally impaled through the forehead with a bone, dying.
