Faith

Rowan was overflowing with Soul Energy after all the time he had spent within and outside the universe, with him.being around the death of so many lifeforms. Even in death, his consciousness still held power and he would not be surprised that for the near million years, he had been harvesting souls.

For a long time he had not been using these souls, he simply prepared himself as he waited for the right moment. Although Rowan claimed that he wanted to perfect his foundation to a ridiculous level before pushing forward with the resource available to him, and while there was great truth in these thought, there was a rather hidden justification for why  he had been gathering soul energy all this while without utilizing them, it was all in preparation for something terrible, but he could not find the source of this fear.
