Owl House: The Wind of the Wolf

Sierra had been abandoned on the streets by her runaway mother at the foot of an orphanage. She had never played with magical animals or people like herself. She'd never ridden a flying staff in the middle of a game. She had never played a magical instrument, meeting witches, or adopted by a witch. All Sierra knows is a quiet life at the orphanage.
But all that is about to change when a witch had adopted her after Sierra had went through a portal and they both started a gang to rebel against the Emperor Belos and his allies. But Sierra soon meets a witch from her adoptive parent's past, the witch's apprentice, and their allies.

(Don't worry, I'm writing for fun).
