The story
No god blessed him. Three of them trained him.
Everyone laughs at Arion. He's a bastard with no blessing from any god, and they're sure he has no power at all. He enters the brutal trials at the Athenian Military Academy anyway, and he beats every rival in his way. That's when his three mentors show who they really are. They're Athena, Hephaestus and Prometheus, and they're the gods who picked him. Then the warlord chosen by Hades kidnaps Arion's mother. He has twenty days to get her back, and to do it he'll have to wake the blood of Ares inside him. Will that be enough against a warlord the gods have blessed?
