Tyler Blackburn is going to be conjuring up some evil magic on Charmed.

EW reports that the Roswell, New Mexico actor will guest star on the CW series as as Viralis, a soul-sucking demon with a loyal cult following.

With the power to see into the depths of the human soul, he lures his victims by promising to manifest their greatest desire.

Well, he doesn’t sound like a good guy…

Meanwhile, Leah Pipes will also be joining the series as recurring character Fiona Callahan, Elder Charity’s younger sister and Harry’s former charge.

Fiona is “back in Hilltowne after spending years languishing in Tartarus under suspicious circumstances. Fiona is a witch with a mysterious past and an even more cryptic power. Her release from Tartarus, orchestrated by the Sarcana, could be a blessing or a curse to the Charmed Ones.”

Charmed airs Sundays on The CW.
