It's hard to say what kind of policy the Homeworld Clans will pursue against the Invading Clans. I mean, the Wars of Reaving left a huge mess to clean up, and Abjuration or not, I can't see any Khans wanting to follow in Brett Andrews's footsteps. That doesn't even get into the question of Terra.
Meanwhile, I remember reading somewhere that the Wolf Empire was letting freeborn warriors of sufficient valor challenge for the opportunity to establish a Bloodname house. This is a bit of a shift in Clan thinking, but it opens up the prospect of upward mobility for spheroid freeborns in the Clan warrior castes as well as the prospect of genetic diamonds in the rough to be gained.
Yeah, I don't think the Homeworld Clans are gonna be the boogieman. Expect something new.
