SYNOPSIS for THE ORIGINALS
Fall 2013: Tuesdays (8:00-9:00 pm ET) on The CW!
Family is power. The Original Vampire family swore it to each other a thousand years ago. They pledged to remain together, always and forever. Now, centuries have passed and the bonds of family are broken. Time, tragedy, and hunger for power have torn The Original Family apart.
When Niklaus Mikaelson, the Original Vampire-Werewolf Hybrid, receives a mysterious tip that a plot is brewing against him in the supernatural melting pot that is the French Quarter of New Orleans, he returns to the city his family helped build. Klaus’ questions lead him to a reunion with his diabolical former protégé, Marcel, a charismatic vampire who has total control over the human and supernatural inhabitants of New Orleans. Determined to help his brother find redemption, Elijah follows Klaus and soon learns that the werewolf Hayley has also come to the French Quarter searching for clues to her family history, and has fallen into the hands of a powerful witch named Sophie.
Tensions between the town’s supernatural factions are nearing a breaking point as Marcel commands his devoted followers and rules with absolute power. For Klaus, the thought of answering to his powerful protégé is unthinkable, and he vows to reclaim what was once his — the power, the city, and his family. While they wait to see if their sister Rebekah will leave Mystic Falls and join them, Klaus and Elijah form an uneasy alliance with the witches to ensure that New Orleans will be ruled by THE ORIGINALS once again.
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 (Joseph Morgan), Elijah (Daniel Gillies), and Rebekah (Claire Holt). Now Klaus must take down his protégé, Marcel (Charles Michael Davis), 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. As Klaus has returned after many years, his ego has provoked him to become the king of the city. "Every King needs an heir" says Klaus, accepting the unborn child. The child is a first to be born to a hybrid (part vampire, part werewolf) and a werewolf (Hayley).
