The sky in the underworld was grey, and it looked as if there were layers of dust and fog covering the world above it. Hence, no matter how hard one tries to see it, the main world above was as if it were invisible.
This underworld was the very bottom of the world, and it was a land of death and finality, the end of everything. This was where all of the ghosts belonged as well.
At the moment, all of the ghosts were standing in the underworld, looking up at the sky, yet none of them could see through the layers of fog. It was if they were looking up at the heavens from hell.
The enormous gate to the underworld was towering in front of the Styx, and there was a constant stream of ghosts lining up there, all of them waiting to enter the Kingdom of Death. The only ones who were qualified to line up there were extraordinary in some way, or were sorcerer disciples, magical beasts, titan dragons or from other races, like fairies and sahagin.
