Those of you who've played Castlevania: Portrait of Ruin are already well-aware of Charlotte's penchant for pop-up books. The rest of you would probably like an explanation.

Charlotte is primarily a magic user, but she still has a handful of melee weapons at her disposal, all of which are books. All but two of them have magical weapons and such pop out of them. (As for those other two, they're just books. You can whack enemies with them.) But I figured there was one more book out there in Charlotte collection. One so powerful (yet so private) that it could not be used in the game.

And of course, that book paired with Johnathan and Charlotte's sibling-like relationship could prove to be just a bit counter-productive.
