Library of Sitat'izar

The Library of Sitat'izar is a Nerubian repository of ancient knowledge that was claimed by the Undead Scourge during the War of the Spider. Connected to the Nerubian city of Azjol-Nerub, it is almost directly beneath the Temple City of En'kilah.

Background
The Library housed ancient knowledge from across the world, collected by Nerubian scholars over several centuries. This Library was eventually claimed by the Scourge during the War of the Spider, but was still maintained due to its usefulness to advancing the Scourge's capabilities. With En'kilah serving as an archaeological site for the Scourge, the Library caught the interest of the San'layn and was often visited as a place of research.

Following the War against the Lich King, the forces of En'kilah were severely weakened, especially after the death of Prince Valanar, but the Library remained untouched by the war. Only rumor of a "Scourge reliquary" survived, and no one seemed to be able to discover the entrance to the Library save for those affiliated with the Scourge itself. Inkorkast and Alytheria Bloodmoon were able to return to the Library to explore the roots of their vampirism, during which they discovered evidence of Arbitian and the Mortraust.

During the Blood War, both the Onyx Rose Order and The Silverguard marched on the Temple City of En'kilah believing they could find the reliquary. They assaulted the city and retrieved items of value, but neither order was able to discover the entrance to the true Library beneath the city.
