The aura Ray had seen didn't last for long, but he was sure of it. The feeling that this man by Alexander the emperor's side was the same as both Bliss and Van. For Bliss, the aura she gave off was holy and strong and this was because she was a Divine being.
When Ray had sensed the same thing in Van, he had asked Bliss about it. According to her it was due to there being a so-called God inside him. It was a strange thing to refer to themselves as but there was no other way she could explain it. They were great beings that could last forever and if they did die, they would simply be reborn.
However at times during their rebirth, they wouldn't always find a body. They could just simply be stuck inside another, or even an item. This was what had happened to Van, the queen's son of the Alure kingdom. His powers were strong but they were borrowed from the being inside him, and whenever he would use such powers the Shadow would know. It was the reason why they were after him.
