The series adaptation of Fourth Wing has a new showrunner.

Meredith Averill (Locke & Key, Wednesday) will take the reins of the Prime Video series, based on Rebecca Yarros’ best-selling fantasy novels (collectively known as The Empyrean) from Entangled Publishing. Averill takes over for Moira Walley-Beckett, who left the project in July.

Fourth Wing, named after the first of Yarros’ Empyrean books, is still in development at the streamer and has not been ordered to series.

The potential series will center on Violet Sorrengail, whose plans for a quiet life are upended when her mother, a military general, orders her to join the brutal Basgiath War College and become one of several hundred candidates vying to become dragon riders.

Yarros has published three of a planned five-book series beginning with Fourth Wing in May 2023. It and follow-ups Iron Flame and Onyx Storm have all been best sellers.

Fourth Wing, from Amazon MGM Studios and Michael B. Jordan’s Outlier Society, has been in development since October 2023. Averill will executive produce the project with Jordan and Elizabeth Raposo for Outlier Society, Yarros, and Liz Pelletier and Sherryl Clark are of Premeditated, Entangled Publishing’s sister company. Stefano Agosto, executive vp television at Outlier Society, is a co-EP.

Averill co-created Netflix’s Locke & Key and was an executive producer of Wednesday’s second season. Her credits also include The Haunting of Hill House, Jane the Virgin and The Good Wife.
