The Secret Circle is stocking up on dangerous new dudes in the New Year. 

Michael Graziadei and Sammi Rotibi will both guest-star on the witchy CW series, TVGuide.com has learned exclusively.

The Secret Circle Scoop: There are two of them?! What's next?

Graziadei, best known for playing Daniel Romalotti on The Young and the Restless, will portray Callum, a good-looking but quick-tempered guy with deadly charm. His behavior is especially disturbing to Faye (Phoebe Tonkin).

Rotibi, whose credits include Lord of War and Tears of the Sun, will portray Eben, an ominous and authoritative leader of a dangerous group who's a true believer in his malevolent cause. Sounds like the head of the council, no?
