AU where the ten commandments REALLY take over britannia, They decide to split the land between them. Some went to go stay with Zeldris in Camelot, while the others took land around the area; Leaving liones for the taking. But surprisingly, Monspeet wanted to take liones. Because he thought it would be "interesting to rule over a kingdom."
Everyone was surprised about Monspeet's choice, even Derieri was. So, when they went wandering around the destroyed castle; She asked him about it. He then tried his best to explain without activating his commandment, But then just told the truth because he really wasn't getting to her.
"I did it because i want to rule liones with you."
"with me ?"
Derieri was pretty taken aback by it, and she need some time to recuperate. But in the end, when everyone met up for final decisions; Derieri decided to stay and rule liones with Monspeet.
And yes, they still befriend Annie in the AU. So as gratitude her village is able to move into liones safely, and Annie is turned into a demon (and given a protection spell) to become their forever friend & maid.
