It was near the lowest part in Sunset Shimmer's life. After a series of terrible choices, the once and former apprentice of Princess Celestia was little more than a declawed high school bully in the Human Realm. She'd been defeated by Princess Twilight Sparkle at the fall formal, and left to pick up the pieces of her life—with the help of her princess-assigned friends, of course. Unfortunately, the forgiveness of five girls means nothing next to a school full of people she's tormented for years.
After a foolhardy attempt by her former classmates to send Sunset 'home', the former unicorn has found herself stranded in a world she'd only heard tales of when she was a foal. Being transformed into a form capable of using magic once more should have been a blessing, but instead she's little more than an outlaw. Now she's found herself wrapped up in the adventures of the most wanted witch on the Boiling Isles, her adopted demon son, and a strange human girl from another Human Realm as she tries to find out if it's even possible to go back to her world, or barring that, Equestria.
Crossover with the Owl House focusing on a partially redeemed Sunset Shimmer that has been stuck right in the thick of things with the Owl House plot. How bad can one former unicorn screw things up?
