TV Guide reports Nyssa a Ghul is a powerful member of the League of Assassins who comes to Starling City in pursuit of The Canary.
The Batman villains, the League of Assassins, were introduced this season on Arrow with it becoming known that Merlyn was a member as well. Ra's al Ghul has already been mentioned and an episode was recently titled "League of Assassins," as well.
