If I may, [@DegenerateThree], I don't believe it's specifically the white skin that's an issue here, but more precisely the idea that they can use it to camouflage themselves in heavy snow, which winds up overlapping with what's been put down in [@TheRedWatcher]'s sheet. Not only that particular detail - overlaps of that nature seem to be common - but it's an example.

I will, however, ask you this: if they're historically nomadic sailors, and have only recently settled in Adanion, why is their skin so pale to begin with? Sailing demands a hell of a lot of outside time, and oceans tend to be exposed to a lot of sunlight; alabaster skin would burn horribly under those conditions. It'd make a lot more sense if they were heavily tanned or dark-skinned, akin to Moana's characters if you will.
