Just an idea:
Have you thought of setting the game in around (not) 750 BCE. It could even utilise not-Homer as a key NPC.
That way, you’re around 400+ years after the collapse of the Mycenaean civilisation and the ensuing Greek “dark ages” and just at the birth of the Classical Greek era, but not constrained by the Athens and Sparta of the Persian Wars period ( which is still 250 years in the future)
That gives you much more of a blank canvas on which to paint your creativity, with minotaurs lurking in dark caverns, Pegasi flying the skies and dryads in the olive groves.
There was a major seismic event in what is now Israel in c750 BCE, known as Amos’ Earthquake, so they could be played for all sorts of fantasy scenarios.
Trojan War items, such as the bow of Odysseus, would make great quest items, and you could have the early stirrings of a kingdom across the sea to the west founded by two werewolves named Romulus and Remus, which was 753 BCE according to legend.
Anyway, good luck with the game
