Devil of the Imperial Family

Deep in the palace lies a dungeon. It's filled with the darkest darkness created when the Sun God abandoned the world for 17 months and 2 days. Within, the suffocating scent of death permeates every corner. Every breath is poison and the concept of warmth doesn't exist. In this place, devoid of the conditions for even rats to live... within the deepest halls of this hidden place there is a door. A singular door. The only thing this dreary place was created to do was contain what existed behind that door, because behind that door, was a man feared by the greatest Empire... The most evil creature. The Devil in human skin. The greatest shame of the Imperial Family.
