In the end-game, there's a super dooper character that's suppose to be relevant
to the final battle/scenes to the game. And why the hero has to group up alot of
willing soldiers/etc to end the war, so it isn't the hero that's more important, he does a storyline to finish before the end of the game, sounds like the hero is to Hero of Kvatch is to Martin.

Edit: Excuse me, it's now 116. I don't wanna over do it that much, but the more you collect characters, the more the castle gets populated with bits and bobs.
