- Will of the Emperor – The core chamber of the vaults houses an army of stone soldiers who have been motionless for centuries. They are row upon row of warriors, statues armed for a battle that never began. What treasures do they guard? And what is their tie to the titanic power buried with them here in the shadows?
- The Stone Guard – The first line of defense against those daring to enter the vaults is a stolid row of enchanted, bestial statues. Hard as granite and ceaseless in their vigil, the sentries of the Stone Guard present an insurmountable wall of flame, fangs, and claws.
- Gara'jal the Spiritbinder – Leader of the Zandalar trolls' assault on the vaults, Gara'jal is determined to crack open this trove of ancient mystery and bring back whatever arcane power and knowledge he can find. Gifted with dark talents and surrounded by a loyal cadre of Zandalar mystics, he has broken through the outer walls and will not rest until the vaults belong to him.
- The Spirit Kings – Ancient records tell of these legendary rulers, powerful mogu who carved an empire from the very rock of Pandaria. Their names still cause the land to tremble: Zian of the Endless Shadow, Meng the Demented, Qiang the Merciless, and Subetai the Swift. Some say their spirits lurk in the vaults, lost in ghostly memories of battle and glory.
- Feng the Accursed – Long ago, Feng Shri was the Mogu'shan Vaults' caretaker, tasked with preserving the treasures kept within these shadowy halls. After years of faithful service, he was caught stealing from the shelves (although some say he was framed by a jealous underling) and the mogu ruler punished him with a fatal curse. The doomed spirit of Feng Shri has wandered the vaults ever since, communing with the shades of past mogu heroes and warlords.
- Elegon – Dedicated to the advancement of their empire, the mogu salvaged and repurposed titan technology to generate untold power in the depths of this ancient complex. Why these energies have been focused into the cold will of a celestial dragon is a mystery that lies at the very heart of the vaults.
