Lost Reading Room
A fabled part of Unseen University Library that, owing to the peculiar spatio-temporal field and the operations of L-Space, remains lost to the world. (The Librarian probably knows, but hasn't said an ook on the subject.) Expeditions composed of bold and brave wizards are occasionally sent out to locate it. These expeditions are commonly composed of student wizards, and tend to be organized by students after hearing their seniors babble about their attempts and becoming convinced they can do better. The last such mission ended up lost in the aisles and had to resort to eating its own boots (and the boots from the remains of the previous expedition) before it made its way back to known shelves and safety.
