Plague Knights is a name given to the mounted elite from amongst the Chaos warriors whose patron is Nurgle. They are infected with all manner of crippling diseases and are motivated by a strange morbid energy. This enables them to survive blows which might otherwise slay another Chaos Knight. Their originally splendid wargear, coats of arms and banners have become tattered and dirty like the rags of lepers. Their silk and fur cloaks hang from their shoulders like the shrouds of a corpse. Many Knights bear their disfigurements openly and are quite proud of their bloody sores and discoloured skin. Others cover their shrivelled limbs and leprous faces with bandages. Some hide their faces behind bizarre carnival masks with absurdly grinning or grimacing faces. All Plague Knights ride Rotbeasts because their crippling diseases make it hard if not impossible for them to move about unaided. Fat flies swarm about them, crawling in and out of their robes, and where their Rotbeasts’ feet tread the soil, maggots and worms spill up from the loam. They are often accompanied by a Nurgling which perches on their saddle or shoulder, or which hangs to their horse harness, gurgling delightedly as the Knight charges into the carnage of battle.
