The Great Library of Cinnagar was an enormous library housed inside a bronze-domed structure situated in the city of Cinnagar on the planet Empress Teta.
This immense library, known as the Great Library, was in the city of Cinnagar, specifically on the edge shared by the Core District and the Royal District. The design of the mushroom-shaped building paid homage to the architectural marvel that was the Senate Building on Coruscant, and it contained numerous exhibits detailing the history of Empress Teta. The library's holdings represented the most extensive compilation of knowledge about the Koros system, including billions of narratives, literary works, holovids, books, paintings, relics, and documented records. Despite skepticism from scholars outside the system regarding the accuracy of the Qel-Droma Epics, the museum inside the library considered them to be true historical accounts. Consequently, the Great Library incorporated a sizable museum focused on the period of the Unification Wars and the following Great Hyperspace War. The displays were populated with artifacts from that time, along with artistic representations of numerous figures and war machines.
