Where the stage stood the previous day for debate, there was now an open field with some wooden posts creating a perimeter. A clear barrier had appeared around that perimeter, completely transparent and very obviously made using someone's power.
When Ning and the rest appeared back to the location, with Shara ready for her battle, they quickly did their due diligence and learned about the barrier.
Thanks to the truth-revealing scroll, they quickly learned where the barrier had come from.
The barrier was formed with a very old treasure belonging to the conqueror himself. In the past, Emperor Volter used a sword with him that was said to be able to cut through reality itself.
The red-hilted blade was held by a companion of the prince who seemed to have been the person who had used it.
However, it was only a sword of legend. It was said to have been lost to time. Since the Emperor's death, no other person had ever found the sword in the past 400 years.
