A spin-off from The Vampire Diaries and set in New Orleans, The Originals centers on the Mikaelson siblings, otherwise known as the world's original vampires: Klaus, Elijah, and Rebekah. Now Klaus must take down his protégé, Marcel, who is now in charge of New Orleans, in order to re-take his city, as he originally built New Orleans. Klaus departed from the city after being chased down by his father Mikael, while it was being constructed and Marcel took charge.
