Xanthos is a young, athletic warrior. He wears the full kit of a hoplite, with an owl's head crest on his shield. At 19 years old, he's been fully trained in combat and is quite skilled, but he's still young at heart and a bit naive at times.

Xanthos's father was a merchant ship owner, but during an extreme storm at sea, his father made the mistake of cursing Poseidon for sending the storm. The family's substantial fortune was soon gone, as mishap after tragedy whittled it away. Sure that the Lord of the Seas had cursed the family, Xanthos dedicated his life to the Warriors of Pallas, a group dedicated to protecting the weak. Xanthos hopes that by gaining glory, and maybe the blessings of Pallas Athena, he can break the family's curse.
