Where is My Sword

On a solitary peak stands a lone swordsman, his iron blade raised against the heavens themselves. When colossal eyes pierce the sky and a godlike palm descends, his defiant roar shakes the world. He will become a demon to save all creation. She will forsake immortality to stand beside him. In a universe where gods toy with mortals and destiny is written in blood, one question echoes through eternity: Where is my sword?
