Well surprise, surprise!

Our transformed King thought he was banging a nasty witch, but what he was actually drilling was a demi-succubus practicing to become a witch!

She's not very skilled at the witchcraft, but in the end all is good - she finds she prefers her King just the way he is; lots of (to her) tasty cream to be enjoyed. Among other things.

Demi-demons in my 'magical future Earth' are the ones sired/whelped on Earth and not spawned in the Pit.

King Alecrast has dispelled her cloaking charm and is now working on getting her to reveal her 'true' name to him. At the moment he only knows her as Alicia; but he also knows a demon/demoness will never tell you his/her true name right off the bat.

The necklace around Alicia's neck actually belongs to Alecrast. It's magical properties have overpowered Alicia's weak magical aura and revealed her true form. She has been 'de-cloaked'.
