I'll try to think of something, but that was a character I brought over from the original RP. The alabaster skin is supposed to be a trait of all Sjamyyki, so changing that alone is going to need quite the overhaul. Alternatively, I can just adjust certain bits and bobs of his appearance, but I doubt it'll be that much of a difference.
I mean, I don't particularly mind or see the issue with having characters that are similar - even to that extent. Having a bit of confusion here and there could lead the plot down pretty interesting lines. Vaakjarki also has the trait of being rude and silent, so that's one point of separation at the very least. If the similarity in appearances is truly a bother, I'll try to do something about it but I can't promise much because, again, that's not just Vaakjarki's look; it's something common to all Sjamyyki.
