The second floor of the library is a maze of rooms that run off the mezzanine up a few stairs into secrets to be discovered one at a time like the blooms of a rose bush.
Here there are offices and storerooms of necessary things that no one wants to go down to the basement to bring upstairs. There is no grandness of space, no colossal images hung on the walls nor the shelves so high you want to climb them.
The most fun on the second floor are the classics and musty volumes of illuminated manuscripts locked away from the general public. The most fun way to traverse the second floor is to catch your breath on the mezzanine away from the explicit order of the interlocking rooms and look down on the crystal crown of the king before mingling with peasants in the first floor lobby or the ghosts that haunt the basement rooms.
