Suggestions with Race/Class ComboFollow

When I am getting ready to create a new character, I like to try and think about who the character is, what their attitude is like, and what kind of impression they would give other players. I recently saw a fellow player as a female Iksar. I have never had a desire to play an Iksar, nor a female character. For some reason however, it inspired me to want to make one. My first impression of the female Iksar was "cold hard *****". I loved the idea of this.

So, this begs the question. Which class would best fit this persona?

Another adjective that came to mind was "calculating"... I was thinking possibly Assassin?

My main is a female iksar assassin. I love it. Assassin fits her perfectly.
