Zaxary, Barne, and Naley worked together while Sofiel sang some song for them.
Apparently, Sofiel's song was quite effective in giving them a thought of inspiration. This was because her song moved not only the heart but also the mind. Her voice was as magical as true magic, but unlike magic who had rough side effect on the mind, her voice was subtle and soft, causing no side effects.
Magic was like a pill. If someone consumed it too much, they would get overdosed, but her voice did not had side effect.
If Aldred could bring her back, she could inspire millions to reach their full potential. Most people did not reach their full potential because of many things; depression, laziness, etc.
They were too afraid to try, to lazy to stay consistent, and too unmotivated to even began the first step that they did not know how far they could have went.
