The Owl House, with characters aged up slightly, beta designs, a mix of the beta personalities and canon personalities.
If you loved the show and what it had to offer, here is a retelling/adding content story, that expands on aspects of the show and deals with some slightly more mature themes.
Luz Noceda is a slightly troubled 17 year old, barely passing high school, her mom believes it best to send her off to a place that will set her up for the next step of her life. She has Luz all packed and ready to go to Summer Camp - Reform and College Readiness.
All Luz wants is to make her mother proud, she may crave to be understood but she needs to make her moms life as easy as possible. Which may turn out to be more difficult than she thought when a certain owl steals her favourite book and leads her into the most horrifyingly magical place she has ever seen.
This will contain mature themes. (Smoking, sex, drugs, anxiety, panic, disassociation, abuse and eventual smut, lots of fluff)
