Well, when people lose the duel during The Seal of Orichalcos, a dark energy envelops them and drains their life force, turning them into soulless husks controlled by the evil power of the seal. It's like they become mindless zombies, wandering around in a trance like state, only able to do the bidding of the seal's master. It's up to our heroes to save these lost souls and break the hold of The Seal of Orichalcos before it's too late!
