"A long time ago, there was a Gaelic coven I stumbled upon on my travels after leaving Hogwarts, before becoming an Archfey. That coven was named Cùmhnant a ’chridhe buille, which translate to Coven of the Beating Heart.They had a sect, known as Brathadairean or Spellbinders in English. The Spellbinders ideology revolved around mages who would alter their bodies to be the guardians of the coven. I underwent their ritual that shields the mind."
