The Plague Monks are the fanatical warrior-devotees of Clan Pestilens, the pestilent faction of the Skaven who worship disease itself as a holy sacrament. Wrapped in filthy, rotting robes and armed with rusted, corroded blades, they hurl themselves into battle in a frenzy of religious ecstasy, heedless of their own wounds.
These ratmen believe that pestilence is the true face of their god, and they cultivate every festering malady upon their own bodies as a mark of devotion. In combat their sheer numbers and suicidal fervour make them a churning tide of contagion, spreading rot and plague to any foe unlucky enough to be cut by their diseased weapons.
Led by chanting Plague Priests, the Plague Monks form the black heart of Clan Pestilens armies, their zealotry so total that they welcome death in battle as the highest communion with their loathsome and unclean deity.
