The Dolorous Gnaw is a warband or vectorium of the Death Guard Traitor Legion's 3rd Plague Company. Noxious Blightbringers are especially prevalent in the vectoriums of the 3rd Plague Company. Such warbands as the Putrid Choir or the Dolorous Gnaw rarely take to the battlefield without two or three Noxious Blightbringers to herald them into battle.
The Dolorous Gnaw's Power Armour is the same as that of the Death Guard, composed of decayed and cracked plates of ceramite, though its colours are unknown. The Dolorous Gnaw's Chaos Space Marines, like those of their fellow Death Guard, often wear grotesquely warped suits of antique Mark III Iron Power Armour.
The Dolorous Gnaw'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.
