Has there ever been clarification on just what the history is that the Au Ra have with Garlemald? Previously, all we knew is that Othard is under Imperial subjugation, but the backstory we've been given with the Auri naming conventions doesn't make any note of this.
It seems like this would especially be a massive, traumatic, end-of-an-era type turn of events for the highly independent Xaela clans, and so it's conspicuous that this gets no mention. Maybe less so for the Raen, with their very regimented society, but we know many live in Doma, and resisted as citizens of that nation.
Would the Garleans even attempt to assimilate them? Would they conscript Au Ra into their legions, the same way there's a signifact number of elezen and roegadyn (and a small handful of miqo'te and lalafell) among the soldiers we see? Would they perceive them as a beast tribe and simply try to exterminate them, or is that approach saved exclusively for groups that openly worship Primals?
