Scáthach (portrayed by
Lady Gaga) is an immortal English woman descending from the Druids and their Roman conqueror, and a practitioner of prehistoric Celtic religion and worshipper of Old Gods. She was a stowaway on a British voyage destined for the colonies, but the ships occupants all died. The colonists discovered her upon landfall and blames her presence for enraging the sea gods. She was subsequently imprisoned and sentenced to be burned at the stake for witchcraft. Using her darker powers, she massacred the soldiers. This was later blamed on Natives, and Scáthach escaped into the wild. In 1590, she encounters a dying Thomasin and saves her from a wild boar attack. In return, Thomasin swears allegiance to her and becomes her holy figure. She requires a human sacrifice annually, and in return for Thomasin carrying this out, she provides her with food. When colonists begin rejecting the practice of human sacrifice, thereby negating Scáthach's flow of human sacrifice, Scáthach assists Thomasin in poisoning the Roanoke colonists, thereby binding all of them to the land. Scáthach is also infatuated with Matt, using her powers to place him in a trance so he will commit himself to her. She rescues Lee in a similar fashion to her rescue of Thomasin, both falling victim to a wild boar. She asserts Lee as her thrall, again, presenting her subject with a heart to be consumed. It has also been confirmed by creator Ryan Murphy that Scáthach is the first Supreme of the line of witches who appear in
American Horror Story: Coven,
[1]which means she possesses unlimited powers, and is the ancestor of the witches featured in Coven.
