Star Trek Enterprise star Jolene Blalock is set to to guest star on Legend of the Seeker "as Nicci, a mysterious Sister of the Dark who finds a fun plaything in the form of Richard."

"She finds intrigue with Richard because he has this incredibly powerful magic that he doesn't know how to use," she told me this week from L.A. "She feels with Richard she has finally found an equal and that makes it fun for her. Before she had been playing cat-and-mouse with the Sisters of the Light, but when Richard shows up, it's as if the game is on."
