Plaguebearer

The Plaguebearers (aka Tainted Ones, Maggotkin, Rotbearers, and Tallymen of Plagues) are the vile Lesser Daemons of Nurgle. Charged with counting all the poxes and contagions in the world, they breach the boundaries between the mortal world and the Realm of Chaos to spread woe and despair, spilling their filth wherever they go. And in their deep bass voices, they mutter and grumble, naming and counting the diseases that afflict mankind.

The Maggotkin are especially foul, humanoid in shape but savaged by sickness and hunger. At the centre of their being is a grossly distended abdomen, split in places to reveal the gushing organs within and the wriggling maggots that feast on the rot. Resting above this prodigious bulk is a gaunt rib cage covered by thin green or ochre flesh that testifies to their master’s nature. Two spindly limbs just barely bear their sack-like bodies, bent by pestilence so virulent it warps the bones.

Of all of their features, it is the egg-shaped head perched on a thin neck that’s the most disturbing. Its single, large eye situated in the centre of its face weeps thick sludge, shadowed by the horn that pierces the cankerous flesh on its brow. Beneath the eye is a wormy mouth, slick with the filth dripping from is rolling eye. It is a thing to be detested, but it is a thing of power.

Venerated by the Chaos cults of the Lord of Despair, the Tainted Ones are living symbols of Nurgle’s blessings, personifying all that the Dark God is. By embracing the nature of these fiends, the cultists learn to accept their own corruptions and grow beyond them. Those few who foolishly stand against the Plaguebearers, they learn a terrible lesson about slow, leprous death.
