When the season finale of American Horror Story: Coven, "The Seven Wonders", airs tomorrow night on FX, fans will know once and for all who the new Supreme is. To get fans ready for this big revelation, the network has released a new featurette that delves into the history behind the Supreme selection process known as The Seven Wonders.

Executive producer/writer Tim Minear explains how current Supreme Fiona (Jessica Lange) stole her inheritance, which lead to her being the worst, most narcissistic Supreme there is, while writer-executive producer Jessica Sharzer talks about how Fiona is trying to identify who may become the new Supreme, so she can eliminate her. Of course, whoever the new Supreme is will steal Fiona's powers, as explained by Douglas Petrie, who also breaks down the history behind The Seven Wonders selection process, which will determine who Fiona's successor will be. Who do you think will take Fiona's place? As Taissa Farmiga reveals, it's down to her character Zoe, Queenie (Gabourey Sidibe), Misty (Lily Rabe) and Madison (Emma Roberts). Find out when the American Horror Story: Coven season finale airs Wednesday, January 29 at 10 PM ET on FX.
