Couldn't that just be one of the already in-game races just face painted or something?
That's what I thought at first. Or that it was just a mix of someones tattoos (zabrak) and dark side alignment, but I don't believe the hair and the face markings support those theories. I think that the face markings match that of what is seen on Nadia Grell (similar markings on the cheeks and eyes). I can't find any more images of her race to see if they have skin that light though. I suppose it could also be a combination of legacy unlocks as well..
