The Library is an entity first encountered during chapter 8, Shipping off to Southden. It manifested as a massive expanse of bookshelves spanning as far as the ear can see in all directions.
The current entrance to the library is located within a building enclosed within one of Southden's many domes.
The library summoned Jane for the purpose of giving her Geoangular Control. In order to do this, it contracted the Tradesmen to send Jane a cryptic message and rearranged how Fuse learned of it retroactively.
The Librarians are the guardians of the Library, and will attack any perceived threat to it. They do not seem to possess fully physical forms, though Caius was able to interfere with one by grappling it.
