That is purgatory.
The violence that makes even the fiercest hell tremble and the cold-heartedness that makes the coldest hell step back, a place more dangerous and deadly than hell itself, that is purgatory.
Ghosts and souls, as well as creatures of the mortal world, dare not approach, only to watch from afar, at the heart of purgatory, where two alien forms are intensely battling each other.
In fact, they are the very essence of purgatory, creating this hyper-speed arena of purgatorial combat, every maneuver, every attack, makes purgatory even more lethal and insane.
The wind howls, thunder and lightning roar.
