I’m considering a name change. What if we rename the mainland continent of Hyperborea to “Thulia” and the old Hyperborean race to “Thulians”? (The game world as a whole would remain “Hyperborea”.)
Hyperborea is mouthful, although I love it as the name of the “flat earth” realm of AS&SH. And Thulia has the right combination of weirdness and menace for the pale-skinned people of old.
I’ll mull it over for a while, then maybe do a bulk name change across my campaign.
