Lucy Griffiths has landed a major role on season five of True Blood.

The British actress, who has scant experience on American television, will come on board next summer as Nora, the ancient quasi-relative of Eric's who was also created by Godric. Look for this key character to be working as a double agent for the Authority.

Nora will know Eric well and care for him passionately... but her dedication to the Authority will cause a major riff between "brother" and "sister," considering how season four concluded with Eric and Bill agreeing to team up against Him.

Nora is the first significant vampire to be cast. Look for a bevy of werewolves to soon join her in Bon Temps.

Filming on season five of True Blood kicks off the week after Thanksgiving.
