Interaction with Mortals
Nurgle hates mortals with a burning passion. He close to never associates with them, much less speaks with them.
Nurgle's most notable business ventures with mortals include the creation of every disease and sickness in Existence, the engineering of the Black Plague, and the invention of pain. Nurgle created these things as a means to harm and torture mortals. Nurgle's only true culture of followers is found in the Skaven - fierce, ravenous ratmen who have mastered the arts of weaving disease and decay. The Skaven worship him in the form of the Great Horned Rat. Otherwise, Nurgle is hated by mortals, and he hates them more so.
However, in very rare instances, Nurgle may decide that a mortal may be a worthy tool for his purposes, a vessel for spreading decay and suffering. However, this is only if the mortal prays to Nurgle religiously, and indulges himself in sickness and horrid practices. Once the mortal has learned to love the disgusting blessings of the Unholy Father, finds the ecstasy in pain and torture, and cherishes the scent of decaying corpses, can one gain his favor. The mortal will be corrupted and turned into a Nurgling, and they would have the power to masterfully spread disease, and not suffer debilitating effects from pain. However, as is the case with all Dark Champions, their souls would be claimed by the Dark God, and they would become little more than food for their distended Dark Master.
