The Wheel of Time is bringing a key character from its source material to the screen.

The Prime Video series has added Emmy winner Shohreh Aghdashloo to its cast. In The Wheel of Time‘s third season, due in March, Aghdashloo (The Expanse, House of Sand and Fog) will play Elaida do Avriny a’Roihan, an important character in the fantasy novels by Robert Jordan on which the series is based.

Elaida is described as “a ruthlessly powerful Aes Sedai as proficient in politicking as she is in channeling. She has a deep history with Moiraine (Rosamund Pike) and Siuan (Sophie Okonedo), and scores to settle with both of them when she returns to the White Tower. Elaida is someone who believes in ends over means, and is willing to do anything to achieve what she envisions to be the greater good.”

Prime Video recently unveiled a teaser for season three that shows Moiraine warning that she has seen “a thousand thousand futures,” all of which portend that either she or Rand al’Thor (Josha Stradowski), the young man who may hold the future of humanity in his hands as the Dragon Reborn, will survive — but not both of them.

Aghdashloo joins an ensemble that also features Daniel Henney, Zoë Robins, Madeleine Madden, Marcus Rutherford, Dónal Finn, Ceara Coveney, Kate Fleetwood, Natasha O’Keefe, Ayoola Smart and Kae Alexander.

Sony Pictures Television and Amazon MGM Studios produce The Wheel of Time. Rafe Judkins is the showrunner and executive produces with Rick Selvage and Larry Mondragon of Iwot Productions; Ted Field of Radar Pictures; and Mike Weber, Marigo Kehoe, Ciaran Donnelly, Justine Juel Gillmer, Dave Hill and Pike.

Aghdashloo is coming off a recurring role on The Penguin at HBO. She won an Emmy in 2009 for HBO’s movie House of Saddam and was nominated for an Oscar for House of Sand and Fog. Her recent credits also include The Flight Attendant and voiceover work on Archer, Netflix’s Damsel and Arcane and Ghostbusters: Afterlife.
