Once all people received Souls and incredible powers. Some were lucky enough to obtain the Soul of an ancient and powerful creature, but fate was not favorable to all. The world began to change, and creatures evolved. But, it was not the beginning of a new era. It was the end. A couple of months later, a dark mist appeared and destroyed the world. It was a dictate of destiny from which no one could escape. Wain Norheim was the world's best assassin and the only one who didn't get a soul. However, he was destined to gain the power to confront fate. Escaping through a portal into another world, he unknowingly began the apocalypse. Even the world failed to expel him.
The explosion of the dark orb was the final stage in their battle, as it not only inflicted mortal wounds on August but also helped Ern, Erza, and Alas deal with the other Elves, so the camp was already destroyed.
After defeating August, Wain received the final key.
[Wrath Key (Unique)
This key was received only by the one who was able to pass a special test and show his wrath. It is the road to the most powerful Spirit in history.]
Whoooooosh.
The rest of the keys shone brightly as they flew towards each other and formed a circle.
