The casual massacres and totalitarian Red Paladins are undoubtedly scary. But even beyond the violence, we also get other creepy factors thrown into the mix that legitimately give the show The Conjuring and American Horror Story vibes. The appearance of the unsettling black-veiled Widow alone will give you chills. Morgana has a spooky story as well. She later becomes linked with the Widow after seeing her ghostly lover and dealing with the Cailleach (the spider god).
