Starting this fall, it's will be Reign-ing on CW viewers every Thursday night.
With high hopes for this new drama, the network has slotted it after The Vampire Diaries, hoping fans of attractive blood suckers will stick around to learn the tale of Mary Stuart, who the world would come to know as Mary, Queen of Scots.
The official synopsis teases Reign as a series that focuses on "politics, religion and secret agendas of the heart," as Adelaide Kane's Mary gets herself caught up in a "royal" love triangle. Those are the fanciest, most dangerous kinds of love triangles!
Reign also stars Toby Regbo, Torrance Coombs, Megan Follows, Alan Van Sprang, Celina Sinden, Caitlin Stasey, Anna Popplewell and Jenessa Grant.
Look for a trailer later today and click through images from the premiere now.
UPDATE: We've added the first Reign trailer!
