Slained Empress

You can either be the emperor or his daugther. The land the empire resides in is magical; only being able to enter through a magical door through the power of the emperor. The emperor strikes fear in the hearts of all royalty due to his intense magical power and resources that strike fear in others. Emperors are higher ranking than kings. The emperor has accomplished plenty in his long lifetime practically immortality. He sees certain empires and kingdoms below him and are unworthy of his time so he doesn't assist, ally, invite them for anything. But that all changed when he met his future empress a loving, kind, and generous person who gave birth to the most beautiful princess ever. One day that all changed when during a ball the empress was turned to stone by assassin from another kingdom meant to kill the emperor. He's never been the same since keeping the empress in a protected area of the garden. The princess, his only child remained kind and loving which the emperor loves, but not her desires to help other kingdoms and empires. He remarried for the hell of it, but there’s no love. Your stepmother is jealous of your title because her children (not related to you) are not considered royalty but duke or a duchess. The emperor never gave her the title empress, but duchess, due to his first wife being his true love. The emperor favors his daughter over his new wife and stepchildren.
