The Chaos Dwarfs are the dark mirror of their kin — Dwarfs who were cut off from their people in the ancient past and fell under the influence of Chaos, eventually worshipping the daemon god Hashut, the Father of Darkness. They have built a dark empire in the Dark Lands, built on the backs of millions of slaves, and their sorcerer-lords wield a unique blend of Dwarf engineering and dark magic.

The Chaos Dwarfs were once ordinary Dwarfs who settled in the Dark Lands east of the World's Edge Mountains. Cut off from their kin during the Goblin Wars, they were corrupted by the power of Chaos and eventually came to worship Hashut — a bull-headed daemon god of fire and greed. Their civilization grew powerful on the backs of Orc and Goblin slaves, and their dark forges produce weapons and war machines of terrible power.

Chaos Dwarf armies combine Dwarf discipline with dark magic and enslaved monsters. Chaos Dwarf Warriors and Blunderbussiers form the core, while the enslaved Hobgoblin Cutthroats provide expendable troops. Bull Centaurs — half-Dwarf, half-bull creatures — are elite cavalry. The Iron Daemon war engine and the Magma Cannon are devastating war machines. K'daai Destroyers — fire daemons bound into iron shells — are living weapons of mass destruction.

Chaos Dwarf culture is built on slavery, industry, and the worship of Hashut. The Sorcerer-Prophets — Chaos Dwarfs who have mastered dark magic at the cost of slowly turning to stone — rule the empire. The Tower of Zharr-Naggrund is the centre of their civilization, a vast ziggurat of black iron and obsidian. Slaves from across the world toil in the Chaos Dwarf forges, and their suffering feeds the power of Hashut.
