Demon Lord that Beat the Prophecy!

It's finally over. The climactic final battle between the demon lord and the heroes of the prophecy has come to a conclusion. The victor left standing is... the demon lord!? Will the demon lord bring peace and prosperity to the world of Alexandria, or will they bring ruin and destruction? Update: Can now choose what type of fantasy world you want to rule! Update 2: Changed some essentials and added options to choose magic preferences and combat style. Update 3: You can now choose to have a family. Let me know what else I should add/change/delete! Pls comment suggestions!
