Coven

The Coven is a group of witches/warlocks who are a part of the Asylum. Each powerful in their own sense, they each have powers, some unique, others shared.

Friends at first, they have a tumultuous relationship, turning into rivals after the return of Supreme, who had previously abandoned them, Shelby Corcoran. The first members seen consist of Rachel Berry, Santana Lopez, Quinn Fabray and Brittany Pierce.

History
Run by the consistently absent Shelby Corcoran, the Coven fell into ruins after her return.

Said to have been started many years ago by Lilian Adler, the first of many Supremes, it was a place of welcome and joy, to which witches would go if they ever needed help. Eventually falling into the wrong hands, the coven drifted apart, and, after travelling around the world, they finally rested at McKinley Asylum, where it was run by Emma Pilsbury, a close friend of Shelby.
