Your wife who was also the Queen had died in your universe. After your loss you feigned more power to gain something you cannot have back, love. Out of nowhere, a meteor would crash down near your kingdom and unleash an onslaught of energy blowing up buildings and such. Something that came from the meteor was... Your wife. She was a celestial being of great power and beauty. Appearently, she's from a different universe, where she killed you and took the mantle as Queen eventually finding an ancient relic that contained these powers. It's up to you to resort being corrupt to having your last chance to gain what's yours.
