“Time for war,” says Mary Sibley (Janet Montgomery) in the new teaser trailer for season two of WGN America’s “Salem.”

Mary’s words carry eerie weight as she sits atop a twiggy throne among heaps of dead bodies. In the upcoming 13-episode season, which will bow in April, the Grand Rite triggered at the end of last season is now underway and death is in the air. In order to bring her plan to completion, Mary must not only control Captain John Alden (Shane West) and the citizens of Salem, but also those lurking in the shadows who seek the power she wields.

The series also stars Seth Gabel as Cotton Mather, Ashley Madekwe as Tituba, Tamzin Merchant as Anne Hale, Elise Eberle as Mercy Lewis and Iddo Goldberg as Isaac Walton.

Produced by Fox 21, “Salem” is created and written by Brannon Braga and Adam Simon. Braga, Simon and Prospect Park’s Jeff Kwatinetz and Josh Barry serve as exec producers.
