It began when Thalia walked through him as if he didn't exist. Her group moved with her, and when he turned around to face them, he noticed that they were no longer the same.
The entire world was twisting and changing. The newly revived Sacred Abyss was being destroyed again.
Why?
Damien purposefully changed his being so that he would not harm this cosmos, so why?
The answer was not one he wanted to hear.
No matter what he did, he was still Absolute. Even if he made an effort to ensure that nothing would happen, he no longer had a choice. The Sacred Abyss inherently feared and worshiped him. It bowed in reverence and automatically treated him like an Absolute.
His any thought would be manifested as reality. The cosmos would change because in its core, it believed that the only way for it to survive was to absolutely bend to his will.
