Coven System

The Coven System is a magic system that appears in the Disney Channel animated series The Owl House. It was founded by Emperor Belos to categorize magic into specific disciplines, and is made up of witches that specialize in a specific form of magic.
To the general public, the purpose of the covens' introduction was for the Titan's sake and to protect the witches and demons from the "danger" of wild magic. However, these claims were simply lies concocted by Belos, who paves the way for a genocide of witches.
