The Tholmic Vault is housed in the mountains between Hammerhall and Nal Crioch. It is the headquarters of the Vault Keepers, and houses the greatest library and storehouse of knowledge in the known world. The Vault Keepers protect and maintain the collection of lore found in the Vault, preserving ancient secrets and collecting new knowledge for future generations. The term “Vault” is well-earned, for the facility itself was designed to be an unbreakable fortress, with dozens of layers of protections to keep out the unwelcome and unworthy. Its defenses have been tested at least once during every Churning, as Zunolosi cultists seek to infiltrate the Vault to steal or destroy the knowledge found within.
