Fate/ Bird of Hermes

Abderus. AKA ancient Greek demigod killed by cannibalistic horses. A side character who only exists to add some spice to Heracles' eighth labor: the Man-eating Mares of Diomedes.
That's me. And I seriously have no idea what's going on nor do I have the foggiest idea what I should do.
All I know is that ancient Greece is filled with overpowered incestuous rapists and bizarre monsters.
Just lovely, wouldn't you agree?
...Now, time to survive.

ATTENTION: This story would be filled with snark, Percy Jackson vibes, and alien nanomachines of Nasuverse. Capiche? Thank you and enjoy!
