In anticipation of the season two return of its breakout original series "Salem" this April, WGN America has released an all-new promo featuring Mercy (Elise Eberle, "The Astronaut Farmer") the Reverend Lewis' increasingly powerful daughter. In the spot, Mercy transforms the symbol of her torment at the hands of the town's witches into a signal of the Witch War to come.
