Library Dawn

Likely the largest library in the world, found in the Capital of Jianghu, Quanzhou. Apprentice scholars of The Illuminated begin there. The bookshelves are made of white oak and the building is as large as a fortress. It's said to contain a restricted private section where the mysteries of the world can be uncovered in written word.
For years following the liberation of Jiuweihu from the forces of Azrael, there was no one designated repertoire of knowledge for the Illuminated. The three founders argued over whose family would hold rights to storing the research of their people. After many heated debates, it was finally agreed upon that one building would be designated, where each of the three founding families, Guo, Fa, and Lu, would build upon.
The Library Dawn. Three expansive floors, each named after one of the three founding families. For the sake of avoiding another argument, the three accepted declaring the floors in alphabetical order. The first being Fa, the second Guo, then the uppermost floor, Lu. Texts pertaining to the sun and the stars residing on the third floor, the second floor on matters pertaining to the spirits and how they influence the world, and the first floor on the knowledge man has acquired in his time on Eternia.
For obvious reasons, the first floor quickly became overwhelmed. Only a matter of years in, the Fa family opted to use their privilege of overseeing the bottom most floor to construct a basement, effectively expanding their influence on Library Dawn. What began as extra storage space for texts relevant to the Fa floor, more scrupulous, questionable documents were stored in the depths of Library Dawn. Some research, such as the quest for the cure to the Curse of Azrael, buried in the lowest floor of the holy library.
Generations passed, eventually the Fa family grew to control the entirety of Library Dawn, the feud over rights to each sect of knowledge lost to time, though not forgotten. Documents pertaining to written agreements lie buried somewhere on the Fa’s original floor.
In light of concerns over unsolicited access, the Fa’s more important documents were shifted to the Lu floor, which became known as the highest privilege to have access to. Even in its time, the Lu floor was considered the ‘holiest’ given its contents pertaining to the knowledge of the sun.
