In your opinion, which hero has the most charisma in the campaign?

I have studied the game and its plot extensively. I have read so much about the heroes that I could write a history textbook, which is what I am currently doing. Ilaya was heard, but not noticed. When Tralsai heard her, he didn't know who she was, and she immediately ran away.
Yes, Tieru is like that! He just knows how to talk someone into doing something, so everyone listens to him, or he'll start lecturing. :)
