The Clayr's Library is a vast archive of magical materials, both written and physical, that extends deep below the Clayr's Glacier. Much of the first half of Lirael is given over to Lirael's explorations of the Library, where she works as a Third Assistant Librarian, before eventually earning a promotion to the position of Second Assistant Librarian.
The library is shaped in a large downward shrinking spiral, reaching from the top of the mountains and down thousands of feet to the very base of the glacier. Along the path of the spiral, in addition to shelves and shelves of tomes, are doors to different chambers often with somekind of large symbol on them. The spiral itself ends its downward path abruptly at the face of a large pale green rock.
The library itself holds much more than books, The Clayr document all of their visions and phophecies. The library is also a museum of sorts and contains various relics and ancient artifacts such as the statue of the Disreputable Dog, clothing of disant cultures, even large collections of different weapons and armor. The Great Library also acts as a prison to at least one Free Magic Elemental which take special care to trap and emprison, such as the Stilken.
Before entering the spiraling passageway of the library, their are several areas for the library staff to attend to their duties. Each Librarian has an individual office of various sizes, according to rank. The Robing Room contains all the initial equipment given to librarians upon their arrival, librarian uniforms, and any additional required equipment.
The Reading room is a large domed room which functions as the central hub of activity in the library. here scholars perform research, Charter sendings fetch and return materials, and Librarians record and index.
Somewhere, presumably connected to the Reading Room is the Junior Librarians' Common Room.
There are five ranks of librarians in the library and the color of their waistcoat denotes their rank. The Clayr who work in the library are all either Third (yellow), Second (red), or First Assistant Librarians (blue), working under a Deputy Librarian (white) and the Chief Librarian (black). The different ranks of librarians also have different levels of access to the library especially in the Old Levels, and these are denoted by the number of emeralds activated by Charter Magic on their bracelets.
Equipment: Every librarian is given, upon arrival at the library, a brass whistle, a small, charter magic, clockwork mouse, a Charter Magic-infused dagger and a bracelet. The whistle loops through straps on the librarian's lapel so that it can be blown if her arms are restrained. The mouse is part clockwork and part Charter Magic, it runs back to the Reading Room and raises an alarm when activated, in case a whistle isn't heard. The dagger is infused Charter Magic spells to combat Free Magic creatures that might be encountered in the Old Levels. The bracelet is silver with mutiple emeralds, it functions as a key to the library's doors with the number of emeralds activated by magic determining which doors each librarian is authorized to enter.
