The Lost Library is the great forgotten archive of Threadbare — vast halls of shelves that stretch into a softly dimming distance, where books shuffle themselves between aisles and footnotes whisper to one another after closing time. Once it held the world's complete record: every saga, every lullaby, every shopkeeper's ledger. Now whole sections are blank, paged through by the Void, and certain corridors lead only to silence. Yet the Library still gathers what it can: stray bookmarks find their way home, and any story rediscovered in the world finds itself, sooner or later, a shelf and a quiet place to wait.
