What is a good name for this character?

I agree with the choice of Amber. I also like the name Katia. Or at least I thought I did, before I saw the no "Cat" and "Kat" names. Katia isn't like Katherine. It's Russian I believe, and it's pronounced (Kart-chya) or something similar to that. It's a variant of Katiya. If you want a Russian name you could do Katia Petrova or Korskaya or something. I love Russian girls. They're really, really pretty. Prettiest Eastern Europeans I've ever seen.
