Most skinwalkers aren't born, they are made just like werewolves but the ones that are born are born human, wolf transformation comes later. Aside fro several inconsistencies the main problem is still present, your being agonizingly vague with his entire past using as few words as possible to describe it. A CS is were you put up all the relevant information for the GM to view. No doubt you know who this character is but unless you write it down I have no way to know what you are thinking. If the village experience is the only thing in his life worth talking about go into as much detail as possible. Try talking about home, life with a pack. I am more that willing to help you flesh out you character but first there has to be something to build on. Right now your CS is just a bunch of vague ideas.
