In a mysterious secret space hidden deep within the Mirror World Tower, countless mountains of white bones stretched endlessly in every direction. Some of these bone mountains were as tall as ordinary peaks, while others looked like small mountain ranges connected together. The entire world was filled with deathly silence, and a cold aura lingered everywhere.
At the very centre of this strange world, there was a gigantic throne made entirely of bones.
The throne was hundreds of meters tall and looked ancient beyond measure. When looking closely, one could see countless faint runes engraved all over the bones that formed the throne. Those runes glowed dimly from time to time, releasing mysterious waves of energy that spread throughout the secret space.
Sitting upon the throne was an enormous skeleton.
