Raen Origins

[Daralii]

As much as I don't think any past animosity that may have existed has any bearing on current Au Ra relations, the answer to this is probably. We know that they originally fought one another in the Before Time, but eventually made peace; we also know that the Raen were largely assimilated into Doman culture as warriors, and currently live in isolated pockets in Othard's mountains, valleys, and seas. There must have been some reason for the mass migration out of the Steppe by the Raen, and the inhabitants of Sui-no-Sato claim to have been "driven" from their homeland, so it's very possible - likely, even - that the conflict ended on less good terms than the folklore implies.

But why would the Oronir, who train from childhood to be warriors, sanitize their own history? If anything you'd think they would take pride in proving themselves the stronger heirs to Azim's legacy.

Well, the conflict in question is part of their set of creation myths, meaning that if it did occur, it could have done so centuries before the modern era. As such, it may be less a conscious sanitation and more the nature of stories that are passed down through multiple generations.

All we know is that there was fighting, that fighting stopped, and now Raen and Xaela live vastly different lives in vastly different locales. I personally think that an entire physically-distinct part of a population becoming a diaspora speaks to something happening; how dramatic that something was is open to debate, especially since it doesn't seem to have woven itself into the cultural memory of either group, but given the words of the undersea Raen I wouldn't dismiss the idea of them being forced to leave entirely.
