The Over City
The third floor, named once in the first book, when Zev tells Carl that 'once you do hit the over city' he will need something compelling. She says the third, sixth and ninth floors are linked in a way that will later become clear, and that they all come into existence at the same time.

Named once, by Zev, as the place where they will need a compelling story: 'once you do hit the over city' (ch. 44). Mordecai's third-floor lectures are off limits until the second floor's halfway point.
