The Coven of the Owl was founded by Rhiannon Fettle, and is associated with the Goddess Bloeddewedd, the woman made of flowers who was later transformed into an owl for her part in the murder of her husband Lleu.
In the times since her transformation, the Coven of the Owl has become one not driven by treachery, but rather wisdom and knowledge, and many from this coven go on to become great teachers and philosophers throughout the wizarding world.
Even so, other Covens view Bloeddewedd with an anxious eye, wondering if, and when, they will revert to their original nature.
The Coven of the Owl is responsible for the Institute’s yearly Yule celebration, staring December 19 and ending before midnight on December 21.
