Generally speaking, the Raen tend to assimilate to the culture around them for the sake of harmony while the Xaela stick to their ancestral culture like glue.
The obligatory informational NPC at Sui-no-Sato claims that the Raen were driven from their ancestral homeland, which would be the steppe (Were she referring to the tribe as a whole), though I suppose she could just be referring to their group which was taking shelter from the wars on the surface.

On a side note, I'm kind of hoping that Yugiri will eventually be allowed back into Sui-no-Sato now that the Garleans are gone, considering that the main reason she got kicked out in the first place was because they were afraid her involvement with Doma would draw the wrong sort of attention to them.
