At long last, Season 3 of A Discovery of Witches has been announced and given a premiere date.

While filming began in late 2020, it wrapped in February of 2021. Now after months of post-production work, the season is slated to begin airing in January of 2022 – nearly exactly a year after the end of Season 2.

What is A Discovery of Witches About?

The AMC+/Sundance Now series A Discovery of Witches series centers on a forbidden relationship between Diana Bishop, a witch (Teresa Palmer) and Matthew Clairmont, a vampire (Matthew Goode). Though initially reluctant to embrace her “witchyness”, Bishop realises pretty early on that denial isn't an option.

What's Happening in Season 3 of A Discovery of Witches?

The Season 3 trailer for A Discovery of Witches premiered in October of 2021 and promises our most epic season yet.  We see that Diana and Matthew have returned to the present day after spending the bulk of Season 2 in Elizabethan England. 

After following the couple and their friends' separate story lines, our cast will finally be reunited.  We are shown that a battle seems to be building between Diana, Matthew, their closest allies, and previously known baddy Peter Knox – and the Congregation.  Are we looking at an all out war between witches, vampires, and daemons as the series builds to its ultimate climax?

You can check out the full trailer below:

A Discovery of Witches: The Books

A Discovery of Witches premiered in September of 2018, and is based upon the best selling “All Souls” trilogy written by Agatha Harkness.  Season 3 will be based upon the third book of the All Souls Trilogy, Book of Life.

What About a Season 4 of A Discovery of Witches?

All the official communications indicate that this is the third and final season of A Discovery of Witches.  Given that the book series is written as a trilogy and each season covers a single book of the series, this isn't surprising – but hopeful fans are quick to point out that Harkness has indeed written a fourth book which centers on Marcus MacNeil, rather than Matthew, and Diana. 

Could this book be the key to a possible fourth season of A Discovery of Witches?  Could it be a pivot point for Marcus to receive a spin off series? We certainly hope so!
