The Tainted Sons are a slow but unstoppable hammer blow, who are known as line-breakers and trench fighters without compare. Under the guidance of their Lord Gulgoth, they have earned a reputation for close-quarters brutality and display both terrifying fire discipline and an obsessiveness with efficiency that borders on madness. Indeed in battle, a favoured tactic of the Warband is to pick a single, priority target and engulf it, in a merciless destructive hail of shots before they move on to other foes. All of these attributes would serve them well when they faithfully fought for years under the Daemon Primarch Mortarion during the countless wars between the Chaos Gods in the Eye of Terror and earned them the blessing of Nurgle. This aided them greatly in battle and when the Tainted Sons were unleashed to wreck havoc outside of the Eye, the Warband discovered Nurgle's blessing still clung to them like miasma. Now the very ground they walk upon curdles into churned filth, while unnatural spores and Warp-tained fumes thicken the air around them and nothing natural can survive for long in the presence of the Tainted Sons. In fact, the very flesh of their foes begins to rot and break out in foul clusters of buboes, as the Warband closes in on them; all while the Tainted Sons gurgle out their warcry, "All will rot."
The Warband fought the Ultramarines, during the Thirteenth Black Crusade and in the aftermath of the Great Rift's creation, the Tainted Sons have conquered several Imperium worlds in Nurgle's name.
