I feel like the reason Empress Rasha and the first prince die in the future is because Blosian (is that how you spell his name) snaps and kills her then himself out of guilt. Or Empress Rasha schemes against the 1st empress (don't remember her name, but she's the mother of Prince Vernon) something, it goes wrong. Resulting in her and her son being executed.
No one thought the possibility that Karina and Rossite are twins? Lol wasn't the empress Beatrice a twin herself
