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

I didn't like Agrael's behavior, specifically that he killed Nicholas. I think it's clear to everyone why he did it. After all, it was because of Nicholas's death that unrest would begin in the Griffin Empire, Biara would usurp power, and many other bad things would happen. On the other hand, as Railagh, he does many good deeds. For example, he destroys the Clan of Grim Hearts, thereby almost completely ridding the underground race of demon worshipers; he helps in saving Isabel; and even before that, he saves her along with Markel from demons, etc. In my opinion, Agrael/Railagh is the most ambiguous hero. Among the Tribes of the East, I liked Kujin. IMHO, he's an interesting hero. From the original game, I liked Zephyr and Godric. From the Hammers of Fate, I liked Wulfsten. He made me laugh a couple of times).
