Careful, Heathens: “Salem” will devour your very soul.

While I’m getting increasingly nervous about The Quiet Ones, I can say the complete opposite about “Salem” debuting April 20 on WGNA.

WGNA continues to unload promos, clips and character bios, so much so that I figured they’d be out of content by now. Yet, with each and every new piece they seem to conjure up something new and invigorating. Take this new spot, for example, which is easily the best thus far. It’s a ferocious look at the witches of Salem, showing that they aren’t the weak and callow martyrs the original promos made them out to be. No no no, they’re anything but, and everyone in Salem better watch their ass…

“Salem” explores what really fueled the town’s infamous witch trials and dares to uncover the dark, supernatural truth behind them.

“Salem” stars Janet Montgomery (“Human Target,” “Made in Jersey”) as the ruthless but vulnerable Mary Sibley, Salem’s most powerful enchantress – and Alden’s onetime love interest; Shane West (“Nikita,” “ER”) as handsome, hardened war veteran John Alden; Seth Gabel (“Fringe”) as local aristocrat Cotton Mather who fans the flames of Salem’s witch hunt; Ashley Madekwe (“Revenge”) as Mary’s mysterious, carnal accomplice; Xander Berkeley (“Nikita,” “The Mentalist”) as chief politician Magistrate Hale; Tamzin Merchant (“Jane Eyre”) as the forthright Anne Hale, an artist with a perilous attraction to Alden; and Elise Eberle (“The Astronaut Farmer”) as the mysteriously afflicted Mercy Lewis.

In “Salem,” witches are real, but they are not who or what they seem. The show, which centers on an epic romance wrapped around this explosive revelation, delivers a bold new vision of Salem – and an even bolder new vision of witches.
