 In it, Nanoha and Fate refuse to seal Reinforce, allowing the Book of Darkness to regenerate its defenses and use the heroes' own dark clones to attack them.In the sequel, "The Gears of Destiny" (2011), the heroines must battle time-traveling humanoid Gears for the future of their respective worlds, and even meet characters from the future (of the main timeline).The first two theatric movies were largely faithful adaptations of the first two anime seasons, but starting with "Magical Girl Lyrical Nanoha Reflection" (2017), the movies' continuity sharply diverged from the main one by cross-introducing the Gears (who are human in this continuity) to the Earth after Reinforce had been sealed.
