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

I liked Agrail because he showed courage by challenging someone much stronger, even though he wasn't supposed to. He could have just stayed with the demons. He doesn't have the same noble ideals as Godric. At the same time, he's not as idealistic as Faydaen, but rather cynical and practical. Unfortunately, I can't say anything about the others, as I haven't fully completed the game (I stopped playing, but I'm playing it again now). Also, Markel is a smart guy; he cleverly orchestrated everything.
