How did Rymrgand become a god?
I think it's cool that Rymrgand claims to be somehow older and more primal than the other gods, and also that nobody seems to question that. Every other god except Berath seems to abhor Rymrgand. So you know the setting still has some mysteries to it. I think one of the clues is in the SSS DLC, where you interact with a ancient avatar of Galawain's and you can feel like its powers are akin to that of Chanters. Another clue is in Woedica's patched in conversation, where she claims that when the gods came into being they adopted the forms of some of Eora's most prevalent myths, and then squashed all the others.
What this tells me is that maybe the Gods weren't just put together like golems. They were summoned. Chanters use magic to re-enact the myths and folklore of the cultures they know, thereby summoning ghosts or storms. The genocidal sacrifices that Engwith engineered were like a massive chanting. That way Rymrgand could be something old, older than Engwith or any other high minded ideal. Or he was summoned to represent that part of the psyche. Or both. This also tracks with how the gods used to have real physical bodies and didn't always exist in the Beyond. Same with how the beyond used to be this chaotic emptiness and was only turned into the Wheel by the Engwithans themselves. The gods of Eora were fashioned out of the collective unconsciousness of all intelligent life as well as the chaotic substance of the Beyond, the same soul magic that powers everything in the setting.
I also like how we got over discussing wether things are RPGs and started discussing wether the Gods are Titans or Demiurges and whatnot.
