Khaz’Vel’Tor is an ancient dwarven fortress built into Mount Vorthrek in the Ashfire Cradle, in the mountains broadly due west of Arkrist. The stronghold is constructed in two major rings around a volcanic core. By the time the Drakefire Phalanx arrived, it had been occupied by a large kobold society organized around worship of the ancient red dragon Zar’Malek, whose lair and hoard lay within the Inner Ring.
The fortress combines dwarven engineering with later kobold occupation. Heat-regulation machinery makes the Inner Ring survivable, ventilation shafts connect workshops, warehouses, barracks, and hidden spaces, and mechanized draconic defenses can be activated from fixed stations. The inner complex also contained thermal equalization systems, steam controls, magma channels, construct-maintenance machinery, and a central caldera area identified on surviving schematics as Emberforge Prison.
At the time of the Phalanx’s infiltration, the spiritual ruler was Scalespeaker Vael Skarrix, supported by Captains Issk and Gravak and the Smolderguard. A dissident faction called the Cinderclaw Cindercate, led in part by the metalworker Rickit, believed Skarrix deliberately prevented Zar’Malek from waking in order to preserve his own authority.
The Phalanx allied with the Cinderclaws, killed Issk and Gravak, poisoned the fortress food supply, and helped create the conditions for an open uprising. They then crossed into the Inner Ring and repaired enough of the ancient thermal machinery to reduce temperatures around the caldera to survivable levels. Reactivating those systems also awakened numerous ancient constructs, forcing the party to race through damaged passages toward Zar’Malek’s domain.
Kada, Dizra, and Quill infiltrated the dragon’s hoard and recovered the Eye of Visthuun. Zar’Malek awakened fully after discovering the theft and began destroying portions of the fortress while searching for the artifact. Dizra severed the dragon’s psychic connection to the Eye, and the Cinderclaws launched their rebellion at the same time. Explosions and collapses temporarily buried Zar’Malek and allowed the Phalanx to escape to their waiting airship.
The final political condition of Khaz’Vel’Tor is not yet known. The uprising was active when the Phalanx departed, Zar’Malek survived at least the initial theft and retaliation, and significant portions of the fortress had been damaged by both the dragon and the rebellion.
