American Horror Story Episode 8.09 Fire and Reign

Dinah helps Langdon and Mead infiltrate the Coven. Mead kills most of the witches, including Queenie, Bubbles, and Zoe. Cordelia is unable to ressurect them as Langdon destroyed their souls. The remaining girls take refuge in Misty's swamp-shack, where Myrtle tells them of an ancient spell can undo past events.

Myrtle asks Mallory to travel to Russia in 1918, and save Grand Duchess Anastasia Nikolaevna, a witch, from her execution. Mallory's attempt to save Anastasia fails, though Myrtle notes that she is the first witch to successfully travel through time. Because of Mallory's near-success, Cordelia contemplates her own death so Mallory can rise as the new Supreme, but Myrtle discourages her. Cordelia and Myrtle find that Langdon has murdered all the warlocks, including John Henry and Behold, at Hawthorne's School.

Mutt and Jeff, who have been controlling Mead the whole time, meet with Langdon and inform him that the Cooperative is the ancient Order of the Illuminati, an organisation made up of world elites that have sold their soul to Satan. Langdon meets with the Illuminati, informing them of the Outposts and begins to plan the end of times.
