No one knew what a Nova was until 200 years ago. Everyone was aware that some people could grow their powers somehow, but no one truly know anything about it.
Given that the number of people capable of doing so was so extremely low, no one truly had any idea of exactly what was going on.
That was until one person gave an explanation for everything.
It wasn't known where the word came from, but he called these people Nova. He also explained how Nova were people that collected the souls of the dead to empower themselves.
Images of Novas played on the screen, along with a small animation of how a Nova got stronger.
"There is a video available of what was leaked to the world. Would you like to view it?" the room spoke to Stanley.
Stanley wasn't quite aware of what a video was, but since it was asking him to see something, he accepted. "Okay," he said.
