Pox-Wretches are mutants, outcasts from society and among the lowliest of all of Nurgle’s followers. Desperate for their patron’s regard, they embrace filth and disease wholly and utterly. So thoroughly vile are they that they attract the presence of Mire Kelpies, phlegm-like creatures who shuffle in their wake, enhancing the virulence of the Pox-Wretches’ infections.
