The secret Adari Vaal library was a repository belonging to the Keshiri geologist, writer, and resistance figure Adari Vaal. This library resided within a concealed chamber of Vaal Hall, situated in the city of Sus'mintri. Its construction followed Vaal's exile to the distant landmass of Alanciar. Within its walls lay all the literary works crafted by Vaal during her Alanciar sojourn, notably including her personal memoirs. In the year 2975 BBY, Jogan Halder and Quarra Thayn brought it to light.
