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.
Wain, Erza, Ern, and Alas moved on. They stuck to their old tactics, they headed for the big roots where the battles took place, and if there was a sign on the root, they waited for someone to pass the trial in their place. They had already passed two trials, so that was enough.
The situation was similar with Markaz, each time, whoever passed the trial was very strong and could escape but had to leave the key behind. Sometimes it was a group of several people, but that was no problem for Wain. Eventually, they were able to collect three more keys in a few hours.
"Well, well, six out of seven." Wain muttered while looking at the keys in his hand, "There's only one left, the Wrath Key. That sounds dangerous."
"Wain, what shall we do?" Erza asked as he approached him, "Shall we go to the gate?"
