Omnitongue Sesquipedalus Dexducapheme is a giant red dragon, and the keeper of the Infinite Library. She is several thousand years old, and is capable of creating powerful enchantments due to both her innate connection to Fantasia as a dragon, as well as her lifelong commitment to scholarship and learning. She devised the spells that enable the Library to house an infinite volume inside a finite surface area. As a dutiful librarian, she communicates psionically instead of using her physical voice.
