No, the distance doesn't look that odd; humans originate somewhere in Africa, and yet human cultures ended up in Patagonia in pre-modern times.CatDoom wrote:I think that, given the distribution of species we've got so far, the hardest thing to explain will probably be how a civilization of nightpeople wound up on that arctic island. The species originated in a desert region, which so far looks like it was probably in the south of the big continent, and it's a long way from point A to point B. They are mysterious and sneaky, though, so the most satisfying answer might very well be "nobody knows..."
The long stretch of oceant they'd have had to cross is harder to explain, OTOH I think nightpeople can survive long ocean journeys more easily than humans do.
