There's small implications in-game about lore and myth. I have ideas, ladies and gentlemen. I want to hear yours as well. I will include a snippet of my headcanon lore if anyone's interested though DM. It leans towards the explicit side(Greco-Roman religion+ a little bit of monotheistic flavour) so I wouldn't feel comfortable posting it directly to a thread.
Let's just say it explains why females weren't introduced until the official version came out and provides insight into why things are the way they are. Dres? Who's that? Neidon, Sarnus? You're crazy.
