Vault of the Wardens is a dungeon located on the Isle of the Watchers in southern Azsuna. This secret Warden facility was carved into the mountainside deep in Azsuna, and sealed with magical wards both to keep intruders out, and to ensure that the terrors locked within could never escape. Many of the most dangerous foes the Wardens have encountered were locked away within the Vault, but in the aftermath of Cordana's betrayal and the Legion's attack, those creatures now roam the halls freely.
