Nordic makes sense, considering the race and queen name, along with rough geographic equivalence. If it does lean that way in the end, it makes me wonder if the naming conventions will include a nod to the other cultures that seem to draw from a similar pool (ie Sea Wolves and some Hyur seem to have a northern/Germanic thing going on), like they did with Elezen and Midlanders / Roes and Highlanders.

Ronso-style naming would('ve) be(en) cool too, IMO.
