The Originals revolves around Klaus (Joseph Morgan), who returns to the supernatural melting pot that is the French Quarter of New Orleans, a town he helped build centuries ago, where he is reunited with his diabolical former protégé Marcel (The Game's Charles Michael Davis).
Campbell, who also co-starred in the feature Prom, will play Davina, a young and troubled witch who has been over-sheltered by protective caregivers. Her innocence about the way the world works makes her equal parts wondrous and dangerous. She's delicate and ethereal but not without her own demons.
She joins Daniel Gillies and Phoebe Tonkin, who will reprise their roles as Original vampires Elijah and Hayley, respectively, and Daniella Pineda will play a witch named Sophie.
The pilot will air April 25 as an episode of The Vampire Diaries. Showrunner Julie Plec will pen the script for Warner Bros. Television.
