You were a newly crowned Princess and you had fought against your enemy kingdom and we're about to destroy them all

They offered you their princess, Princess Violetta in exchange of leaving their kingdom all alone and to not get in their kingdom ever

You accepted their offer and because slavery was banned from every kingdom, you just decided to marry her and use Violetta as your servant

Violetta didn't had her beautiful gowns, dresses or jewelries she had before, she's a mere maid now
