EXCLUSIVE: The more, the merrier. Battlestar Galactica developer/ executive producer Ron Moore has tapped a third co-star from the hit Syfy series, Tricia Helfer, to join his new sci-fi project, NBC’s pilot 17th Precinct. The Sony TV-produced drama is set in the fictional town of Excelsior where magic and supernatural elements rule over science and revolves around the cops at the local 17th Precinct. Helfer will play Morgana, a necromancer, the magical equivalent of a coroner, who is an expert at manipulating the potions, tools, herbs and spells of her trade.

In the pilot, Helfer joins fellow Battlestar alumni James Callis and Jamie Bamber.
