Could you explain a bit about the situation?

Acnologia, the Old King of Uvanis, has been alive and is trying to kill off all members of his kind and grow more power by consuming other universes. He consumed all of his people except Lunar, Sreig, Zecratis, and Astra. And as such marked them as not only a challenge, but to death as well. Since Erza and I are incarnations of them, we are marked as well. Though the mark saps our life force from us the longer we wait, when we do face him, the damage we do to him is much higher and we are more resilient to his attacks as well. Think of the mark as an even playing field. Either way, if he dies, we will be free from the curse upon us and many lives will be saved...
