Kharadron Overlords

During the invasion by the forces of Chaos, many Duardin fortresses were destroyed. Some of the survivors escaped using air-ships and started building outposts in the sky. Some became traders, explorers or pirates. The Kharadron Overlords became rich, building sky-ports across the Mortal Realms.

In the beginning of the Age of Sigmar, the Kharadron Overlords saw the newly arrived Stormcast Eternals. Realizing that they might have a chance, the Kharadron Overlords began to fight against the the forces of Chaos again.
