Ruun's parents were killed by renegade Amazons, who blind ed the boy during their attack. Years later, Hercules freed Ruun from slavery and the two searched for Ruun's sister, Siri. When they found her, they discovered she had grown up to become a confident, battle-savvy Amazon warrior. The Amazon Mayhem had told Siri she was abandoned by her parents, and Hercules forced her to question this story. During a Fire Stakes ceremony in which Mayhem and Siri battled Hercules, Siri discovered the truth: Mayhem had betrayed her. The evil Amazon fell to her death and the siblings were reunited.

When a volcano threatened to destroy the people of Mount Pelion, Hercules decided to blow a hole in the far side of the volcano, allowing the lava to flow into the sea. The Amazon Ephiny joined him, and for a third, Hercules enlisted Kurth, a young man condemned to die for murdering the Centaur Nagus' son. Hercules convinced Nagus to help pull the wagon of explosive crystals. Most of the crystals were lost in a mishap, so the remainder had to be deposited directly in the crater mouth. Kurth took care of this suicide mission, redeeming himself in the process.
