I'm pretty sure it was both in the leaks and shown in the trailer that there's a pretty comprehensive character creator.
It's hard to be certain because we don't know what's PC and what's NPC, but it certainly looked like every house was represented with multiple, visually different designs for the main character.
I'll probably take a really good personality test online and go with what that says. Also the description says we could use ancient dark magic and be evil or something so im all for that.
