Giant Capstone
The Giant Capstone is a massive stone disc that forms the primary seal between the Dwarven Layer and the deeper containment strata in Kazad-Khrom.
Description and Function
Approximately forty feet in diameter, the capstone is inscribed with ancient Giant-era containment runes. It was engineered not merely as a physical barrier but as a metaphysical filter, designed to transform The Sleeper's raw psychic emissions into a form the mountain's structure could safely dissipate.
Breach and Current Status
The capstone's integrity was first compromised by the Twisted using the Drowned Juggernaut, which drilled a hole through its center. This initial breach allows The Sleeper's influence to leak directly into the upper layers, bypassing the intended filtration system. The Twisted subsequently attempted a second, larger drilling operation targeting the capstone from a different angle in the deep outer ring. This drill was destroyed by the party, who collapsed the tunnel, but the original breach remains.
