|dates= Late 1200's (burned at the stake)

Sister Agnes was a rogue Spanish nun and hermit witch who was obsessed with undoing [[curse]]s. 700 years ago Agnes locked herself away after having visions of darkness. After decades in exile she would produce the ''[[Book of the Damned]]'', a book made from her own flesh and blood, capable of undoing any type of curse. Soon after the book's completion, the Catholic church hierarchy burned her alive at the stake for heresy.

Rowena relates Agnes' story to [[Charlie Bradbury]], explaining how she made it her life's work to learn how to undo [[curses]] . She discovered that to inflict one curse, Agnes had to know how to inflict another. A balance is required in any struggle between good and how evil; a curse cannot be without its cure. The "cornucopia of curses and satanic visions" led to her being killed executed by the church hierarchy, who wouldn't abide a rogue nun. Charlie remarks that Agnes was ahead of her time. While interrogating [[Eldon Styne]], he reveals that Agnes used a spell to render the book eternal, making it impossible to destroy.

While attempting to recruit [[witch]]es for her new Mega Coven, Rowena tries to entice two witches at a lunch to join her by revealing she is in possession of the ''[[Book of the Damned]]'', written by "crazy Sister Agnes", which is making her a force of nature.
