There was a huge cave in the northern part of the Muivell Kingdom.

It was a limestone cave that seemed to have been cleared up to make a clear floor and ceiling.

A giant hall was constructed inside the cave. It looked like a box with a length of at least thirty meters. There were even multiple floors inside.

However, there was a smaller box that was constructed on the opposite side. The box took up ten percent of the hall's overall size. Its sides were covered with solid walls, while the one facing the hall was covered with a solid wall and curtain so that someone could enter and talk from behind the quilt.

Outside the box stood two people. The first one was an old lady with long white hair. She looked calm and dignified, but her eyes were so sharp that it felt like she was looking at her prey.
