 A distant prequel to this history.

Fantasy TGcaptions: Haloween special - Fool, Voveth Witch and Court Pie

Once upon a time, Badoll was a powerful warlord and wizard.  His horde of barbarians destroyed everything in their path.  When he heard that there was a witch's crown, he immediately set out with an army and found it, but there was a problem.  The crown was cursed.  In an instant, a powerful warrior turned into sexy woman. 

His army, seeing this, fell into panic, but thanks to the spells that were even stronger, hhe managed to keep part of the army on his or rather her side.  This was enough to spread fear across the continent, but in order to maintain the army's loyalty he/she had to have sex with them, which was not a problem because the crown increased both her spells and libido, and as a result she became a nymphomaniac.  The stronger the spells she cast, the stronger her libido was.  Eventually, the rulers of the continent united and defeated her armies, which was not difficult because during the battle she both had sex with her generals and cast powerful spells because her lust was already beyond the scale.  

After she was defeated, it was decided that female witches must be kept short.  Belladonna's fate itself served as a warning, she was locked in a dungeon where lords from all over the continent came to have sex with her, and as a result, many magical children were born.  Belladonna herself finally died after 120 years of captivity, it is said that Belladonna "Lovelace" saw her imprisonment as a reward, her sex drive was already so high that she was unable to think.  This is how the curse of the witch's crown works.
