It was the Chaos Dwarf Sorcerers, also known as Sorcerer-Prophets, Daemonsmiths and Hell-Workers, who led their people from the brink of destruction during the Great Catastrophe and first built the great and blasphemous city of Zharr-Naggrund in ages past, and it is they that still command it today. Their works of sorcery and engineering are legendary, from the great obsidian and basalt towers and ziggurats drawn forth from the earth, and the dark iron towers raised up throughout the Dark Lands, to the steam-hissing engines that crush rock in slave mines and the baroque armour which adorns the Chaos Warriors of the north. All are their dark knowledge made manifest.[2a]
