In his attempt to leave the Dungeon without shedding blood, he ended up causing an unwanted massacre of three thousand two hundred and sixty nine dead, one thousand two hundred and eighty four in coma, four hundred and ninety-five rendered unconscious, and two trapped in an illusion conjured up due to the fear experienced by their brains.
