Nurgle is known also as "Grandfather Nurgle," the "Lord of Pestilence" and the "Lord of Decay." It is the third of the Chaos Gods to fully awake within the Warp, emerging during the 2nd Millennium in the midst of Terra's European Middle Ages, as great plagues swept across the world heralding the god's birth. Nurgle is the Chaos God most directly involved with the plights of mortals, particularly humans who suffer so acutely from a fear of death, perhaps the oldest fear of that species, or any other. While Nurgle is the god of death and decay, it is also the god of rebirth. Decay is simply one part of the cycle of life, without which no new life could grow. In the same way, Nurgle is also the god of perseverance and survival.
