Pulling this back up because I was looking at the naming-lore page and realised that one of the "construction examples" is:

R'Sushmo Rhiki

Sushmo of the Raptors, sired by R’rhiki Nunh (breeding male of the Raptors)
R'sushmo is an actual NPC (she works at the Bismarck), so do we take this as a canon statement that the R tribe is still functioning and has a nunh?
