Kralt was once just another engineer of the Clans Skryre, only set apart from the countless others as the ruler of Clan Refrakd, but all of that changed when his forces joined the Satrap War. A shortage of Warpstone forced him to use Aetherquartz as substitute fuel, and the exposure to the orderly realmstone caused a dramatic shift in his soldier’s behaviour, making them less aggressive and more social; increasing their survivability in battle and decreasing violent arguments. This has sparked an obsession, and now he seeks to study what his minions are becoming, believing that he can change what it means to be Skaven and unlock the true potential of his species without Warpstone’s corruptive influence. But the Council of 13 view his ambitions as madness and depravity, and he must constantly fight to avoid their grasp if he is to survive, let alone succeed.
He is currently based in an abandoned black fortress of unknown origin in the Neonwood Wetlands in Ulgu, where his forces regularly skirmish for resources against the local Unmade and Coalesced, but the recent arrival of a Dawnbringer Crusade threatens to upset the balance of power.
