Mistzug, the god of destruction that invades people's hearts and destroys them. It is unknown whether this god had always been like this since the very beginning. There are only a few lines left of an epic poem that describe this mysterious god of destruction. "Mistzug is only a faint illusion. His appearance is an illusion, and his voice is also an illusion. This god doesn't exist in this world. The only thing present is the jewel of an illusion."
