The name Amyntas means "defender" or "protector" in Greek.
Amyntas is the main character of the story during Xenon and Acheron. His mother is Andara. Amyntas was a child during Anicetus' journey from the Earth to Acheron. During that journey, Anicetus' A.I. chose Amyntas to be its Titanborn. Many years later, Amyntas fought and was badly injured during the Siege of Anicetus. Empyrean forces wiped his memory so Anicetus gave Amyntas the memories of The Soldier of Earth in an attempt to help him recover. When his memories were finally restored he remembered that he was "emperor of titans" and "defender of Acheron".
