Chaos Warfleet - Plaguefleets of Nurgle: Just as the Death Guard have retained cohesion better than many other Traitor Legions, so they also maintain much larger and more organised fleets of voidcraft. These so-called "Plaguefleets" comprise ancient, Horus Heresy-era battleships, stolen Navis Imperialis warships, and even space hulks gathered from the tides of the Warp. It falls to the warriors of the 6th Plague Company, the Ferrymen, to master and garrison these voidcraft, and to liberate new starships that may be added to the Death Guard's rotting armada.The Plague Fleets are vital to the Daemon Primarch Mortarion's gene-sons, for they are the vector by which the Death Guard spread Nurgle's blessings to the wider galaxy. Embarking onto these craft, the Plague Companies of the Death Guard ride the tides of the Warp like wind-blown contagions, emerging into realspace wherever Nurgle wills.While their voidcraft plough through the Immaterium, they fill up with thick clouds of revolting, fat-bodied plague flies and other Daemonic insects that hatch from walls and bulkheads. When the Death Guard land upon enemy worlds or board their victims' spacecraft, these seething fly-storms come with them, spreading infection wherever they go. This has also been used in void combat; Nurglish command vessels can unleash a wide cloud of so-called "void-locusts" around them that start eating away at enemy ships' hulls, while simultaneously regenerating hull damage inflicted on themselves and allied vessels.Should ships of the Plague Fleets be lost or abandoned, they eventually find their way back to the Plague Planet as drifting derelicts to be crewed again. Some believe this is the will of Nurgle. Others claim that once a ship joins the Plague Fleets, its corrupted Machine Spirit is cursed to obey Mortarion until the end of time.Additionally, starships whose crews met their end through disease and decay are the most pleasing sacrifices to Nurgle. Voidships are cramped, claustrophobic places at the best of times, and the air which feeds their living crews is a commodity that must be endlessly recycled and filtered back into the vessel. Such lifeless air as this often becomes stale, and the stench of sweat and grime hangs heavy in it. Additionally, Nurglish voidships often have more numerous crews than would typically be seen on other ships of equivalent size.Under this mask of filth, Nurgle and his dedicated followers find little difficulty in spreading something rather more virulent throughout a vessel. Such plagues aboard ships are not uncommon and Nurgle laughs gleefully at such works. A ship's entire crew may weaken beneath this malady, and in such desperation they will turn to Nurgle for protection -- and so a new Plagueship is born, its crew spared the sorrow of death, but instead gifted an eternity beset by the same plague which first laid them low.But decay does not affect merely the living. Nurgle beams all the more proudly to see the creations of mortals broken down by decay. The most virulent of his ills do not only strike at flesh, but also bring with them a noxious, stinging acidic feel to the air which can sicken even the metal of a warship.Like the bloated and pocked carcasses of his Human followers, Nurglish Plagueships bear these scars of decay like a badge of worship -- liquified rust running like blood across the hull of his Plagueships, cankered and broken power supplies, plasma coils and radiation conduits seeping their magmas like pus. Such decay defines the vessels whose crews serve the Plague Lord.
