Warhammer Age of Sigmar: Nurglings

The rotting bowels of the Great Unclean Ones swell with pus and contagion, and within each such swelling there grows a tiny and malevolent Daemon called a Nurgling. As the Nurgling matures it feeds upon the filth of the Great Unclean One and pops out; the very personification of a boil or pustule. Their tiny teeth are as sharp as razors, leaving festering bites upon their victims, but rarely killing them outright – although such an attack can prove the beginning of a long, disease-ridden demise.
