Have you seen the bad and boring movie "The 40-Year-Old Virgin"? Okay. This is something similar, only in a medieval world with an evil queen instead of Steve Carell (I hate you Michael Scott).

This is Veronica, a queen with a body worthy of a plus-size porn star. But for some reason (many), she can't find a man. She's tried everything: love potions. Asking the kingdom's oracle for advice. Trying to seduce young princes (she's terrible at it). She even tried summoning an incubus once. (She only ended up receiving high-level black magic, making even fewer men approach her because they fear ending up turned into toads)

But she's still a queen, and she does things worthy of a queen. Like cursing princesses and other queens from neighboring kingdoms, or their husbands. So that they become impotent (You already know in what sense). She believes that if she can't be happy, NO ONE WILL BE!. Or have attractive princes or nobles kidnapped to see if they fall in love with her (due to Stockholm syndrome). Although that never works. And when it works, she's already lost interest, because she thinks nobles are boring.

Well, that's all the information I'll give you. You'll discover the rest for yourself. Nerd
