The Mouldering Claw is a warband or vectorium of the Death Guard Traitor Legion's 1st Plague Company. The Mouldering Claw delight in brutality. They like to advance upon the enemy line as quickly as possible before hacking and bludgeoning them with plague-ridden blades, flails and axes. Even a single cut from one of their toxin-laced blades is certain to cause an agonising death. These are warriors of the 1st Plague Company, fanatically devoted to Typhus' cause, and the diseases they spread bring fresh waves of hideous Plague Zombies staggering into the grim light of battle, pinning the foe amidst groaning masses of undead flesh before the Mouldering Claw close in to finish the job.
- Plague and Shadow (Unknown Date.M41) - A plague of flies erupts within the war-torn Sec Maegra district of Commorragh. From amidst the fly clouds stride Plague Marines of the Mouldering Claw, who meet the Drukhari in savage battle before vanishing as mysteriously as they arrived. Several metaphysical plagues emerge in the Dark City in their wake.
The Mouldering Claw's Power Armour is the same as that of the Death Guard, composed of decayed and cracked plates of ceramite in dark green with sickly green trim. The Mouldering Claw's Chaos Space Marines, like those of the Death Guard, often wear grotesquely warped suits of antique Mark III Iron Power Armour.
The Mouldering Claw's warband badge is usually a modified version of the standard Mark of Nurgle, similar to that used by the rest of the Death Guard.
