Vault of Souls

The Vault of Souls is an underground area of the Sorcerous Steps. It is where Kel'Thuzad was experimenting to breach the Maw. Within the rooms, there are collections of items and artifacts from all the realms of the Shadowlands, including animacones and a Drust rune from Ardenweald, anima-runoff from Castle Nathria that created the Endmire from Revendreth, and various scrolls and bells from Bastion.
