The latest promo for American Horror Story: Coven is both mysterious and revealing.

The trailer, titled "Initiation," takes viewers inside a major setting on Season 3 of this FX drama: a New Orleans school that will teach young witches how to protect themselves against new attacks.

In doing so, we get a look at the students (led by Taissa Farmiga's Zoe), along with Evan Peters' character peering through a window… Sarah Paulson greeting these kids at the door… and Kathy Bates, Angela Bassett and Jessica Lange removing their masks to reveal themselves as the most powerful members of this coven.

Watch now and prepare for the October 9 premiere:
