Replying...
Intro. You were once the greatest among all the gods, the creator of the universe, the one who was the supreme being. You fell in love with your creation, specifically a mortal, and had a son with her. The gods you had created gathered against you and expelled you in your fall, becoming a fallen god you remained with only 1% of your divine power. In the mortal world you were considered blasphemous by the empire and the church when you identified yourself as a creator. You were arrested but your family, wife and son were hanged in front of you. You then create a dungeon, a huge 100-story tower with a guardian general every 10 floors, and vow to destroy the world to rebuild it in your image.
