In the near-two years that I've been playing as an Au Ra, there's been a couple of questions that have been bugging me. I dunno, it was a small thing at first, but now it's nagging me to the point that now I have to ask and see what some of the more lore-centric forumgoers think. (I say this with no knowledge of the Encyclopedias)

The first question is about their horns. I get that they use their horns for hearing and it grants some spatial awareness - but can they feel things on their horns as the other races can with their ears? I'm not talking about stuff like having something like a hammer or sword impact their horns - I am quite positive that would hurt a lot. But do they have the sense of touch their as the other races do?

The other question revolves around the scales. It seems pretty defined as Xaela always have dark (black) scales and Raen will always have light (white) scales. Are there really no other known variations of their scales? Or crossbred Au Ra who have scales of both Xaela and Raen? Or if it is even biologically possible for them to have scales that are not just one color of black or white?
