It's been a while since we heard a peep out of the League of Assassins on Arrow, but their leader will apparently be paying a visit to Star City in Season 6.
Executive producers Wendy Mericle and Marc Guggenheim revealed to Varietythat Nyssa Al Ghul (Katrina Law) would return "to warn of an impending danger that will threaten everything we know and love." She'll be dropping by in Episode 16, which will be titled "The Thanatos Guild."
No, Thanatos isn't that purple guy terrorizing Avengers: Infinity War, but we understand the confusion. Thanatos is actually a Greek death god, which doesn't bode well for this episode of Arrow. Either Cayden James (Michael Emerson) is seriously upping his villain game, or something even more deadly is headed our way.
Arrow airs Thursdays at 9/8c on The CW.
