Gender locked race?

iirc the 1st lorebook says that culturally Raen have assimilated but tend to live in isolated villages hidden away in Othard's mountains. The majority of Raen being fully integrated within larger mixed cities is either a retcon or a goof.

That is incorrect. Culture entry for Raen in the first Lorebook: 'The Raen have fully assimilated to the cultures of Doma and Hingashi, and live faithfully according to the regions' traditions. Perhaps owing to their heritage and the status they gained in the service of their warlords, they place particular importance on hierarchy and the master-servant relationship.'

Sorry, it's actually from the character creator/naming convention page in the lore fourm:

Auri creation myth tells of a Dawn Father and a Dusk Mother from whom all Au Ra are descended. The Raen believe their veins to run thick with the blood of the former─their brilliant white scales and iron wills serving as proof of this divine lineage.

Unlike their sister clan, the Xaela, who bloody the land with endless tribal conflict, the Raen have embraced a life of tranquility and solitude, long abandoning the nomadic lifestyle of their ancestors to settle the deep valleys of Othard's mountainous eastern reaches. Only on rare occasions will one emerge from the valley mists to seek adventure in realms afar.

It says they're assimilated to the culture. It doesn't say they hang out with them. It just means when you visit them where they live, the culture you'll find won't be dissimilar to Doma/Hingashi.
