Katrina Law cast as Nyssa al Ghul in Arrow

We've known for a while that the daughter of Ra's al Ghul is set to make her debut in Arrow, but it turns out that it's not Talia (played by Marion Cotillard in The Dark Knight Rises) set to appear in Starling City, but rather the Demon's illegitimate daughter, Nyssa Raatko.

According to TV Guide, Spartacus star Katrina Law has been cast as Nyssa al Ghul, described as "a powerful member of the League of Assassins who comes to Starling City in pursuit of The Canary (Caity Lotz)." Law is set to make her first appearance in the 13th episode of season two, appropriately entitled 'Heir to the Demon'.

Law becomes the latest Spartacus alumni to join the hit superhero show, with Manu Bennett portraying series regular Slade Wilson, and Cynthia Addai-Robinson another second season addition in a recurring guest role as Amanda Waller.
