When Maria said that Wain had caused the apocalypse, he was petrified. He didn't understand how a girl he didn't know could know that.
"How do you know that?" Wain asked coldly, and murderous intent began to emanate from him.
Not only was this girl strong enough to be the first to kill one of the Four Kings, but she also knew something no one else should know.
"I received the power of the world and was chosen. Of course, I know about who my target is and what I must do." Maria said menacingly.
"The power of peace? I see..." Wain muttered. Then all the puzzle pieces came together, and he saw the whole picture.
Because of Maria, a few months ago, the spatial barrier had weakened. Then the world had chosen her as the bearer of its power, and the barrier was temporarily damaged because of the energy surge. The world did this in response to what Wain endured in their confrontation.
