Atrion

The Atrions were the Near-Human species native to Atrios. They were led by a royal family, who included the Princess Astra. During the war with Zeos, they were also led by the Marshall.

The Atrions had a twin planet, Zeos, which they originally traded with peacefully. At some point, a nuclear war started between them and lasted for 5 years. (DW: The Armageddon Factor)
