The Stonevault

Machine Speakers maintain the Stonevault, a facility adjacent to their Hall of Awakening. Their former leader, Void Speaker Eirich, was recently deposed after becoming infected with Void corruption. While Machinists labor and loyalists patrol, Eirich hides behind his most fanatic and corrupted followers. Sequestered behind titan tunnels, he has undergone a terrifying transformation. To ensure he never ascends to power again, your swift intervention is required.
