 This brings him into conflict with Schneizel, who has Nunnally in his custody and commands the "Damocles" (a floating fortress which he intends to place into a position which would allow him to fire nuclear weapons worldwide), and the Black Knights now under Kaname Oghi.In the final battle, as Suzaku fakes his death, Lelouch outwits Schneizel and places him under a Geass command to serve Zero.From there, learning that Nunnally has regained her sight and has been acting on her own plan to unite the world through the fear of the "Damocles", Lelouch uses his Geass on her to give him the "Damocles"' key.
