Shadow Assassin Technique

Dan soon returned to the audience, and Karan took his place. He then began to experience it in a similar manner. No one was paying attention to Karan at this time. On the contrary, everyone was watching Raydon's movements. They were attempting to understand how he accomplished it.

As he stood there watching, Dan's mouth dropped open. How is this even possible? Raydon was standing right next to Karan, close enough for him to feel his breath. But how could he not notice, hear, or feel him? 

They were starting to suspect it was an illusion when Raydon's next words made their hearts race. 

''This is a shadow assassin technique. And your next training will consist of learning this.''  Raydon said calmly.
