I absolutely love this game. So far I have only played a character with evil tendencies but I was impressed how cohesive it all felt in the grand scheme of things. I was not punished for my decision, but rather given different opportunities to exploit. By the end of the demo, I felt both immersed and a force to be reckoned with.
My character was not above ending lives or using others to further her own goals if the benefits outweighed the cons. She's not destructive for the sake of it, but values her own survival above most - a useful, if somewhat callous, trait she inherited from her tumultuous past. Currently, her hound is the only friend she would fight to the bitter end to protect. Time will tell if the same courtesy will extend to her new allies...
Beneath the mask she dons, rages turmoil between what has been done and what needs to be done in order to achieve her goals. She dreams of normalcy and innocence - that which was robbed from her - and is envious of those who have it. She's rational, confident and flirty, with a dash of mirth. She's dangerous, but more than mere cockiness, she has the skill to back it up.

I only have one small thing to point out. Seben's portrait describes her as someone with "no sense of humor" and "playful" at the same time. Doesn't that seem a bit contradicting?
