The void was a concept that was not known to newly awakening planets like New Earth and even most planets of Corey's universe.
There were ancient treasures here and there that used the powers of the Void, but these treasures were exceedingly rare and powerful.
These treasures were usually in the hands of elite organizations of the universe, and some of them were used as trump cards of these organizations.
There were also certain objects that could grant one the ability to have some control over the void, but once again, these objects were rare.
As Corey went through the knowledge he gained on the Void, his eyes glowed brightly like a child that was watching their favorite show.
What was the Void
Most would say that the Void was the combination of space, time, and a destructive force. While some might say that the Void was a higher form of space and time combined together.
