Changes

The ''Terminus Est'' and Typhon reappeared on [[Ynyx]] and upon the First Captain's request Mortarion himself agreed to journey on the vessel to [[Terra]] instead of the ''[[Endurance]]''. However this was part of Typhon's elaborate plot to corrupt the Death Guard, and in the subsequent trap within the [[Warp]] the ''Terminus Est'' along with the rest of the Death Guard fleet became daemonically corrupted.{{Fn|3}} When the ''Terminus Est'' was sighted as part of the armada that followed [[Horus]] to [[Terra]] it had changed. The Mark of Nurgle was upon it and all the other vessels of the Death Guard. While [[Mortarion]] led the assault on the Lion's Gate starport, Typhus controlled the Plaguefleet and it is suspected actually began the orbital bombardment of the Emperor’s Palace.{{Cite this}} During the [[Siege of Terra]], the ''Terminus Est'' took part in the destruction of the Emperor's flagship ''[[Imperator Somnium]].{{Fn|4}}

Following Horus’ death and the arrival of loyalist reinforcements the ''Terminus Est''’s formidable reserves of attack craft were expended as a rearguard while the Death Guard were evacuated back to their ships. Along with the rest of the [[Traitor Legions]] the Death Guard fled to the [[Eye of Terror]] and disappeared from Human knowledge for centuries.{{Cite thisFn|2}}

In the Eye it is suspected that the Traitor Legions fought amongst themselves. It is the boast of the Death Guard that their Primarch-turned-Daemon Prince Mortarion conquered a mighty empire within the Eye and transformed it to his own tastes. Typhus and the ''Terminus Est'' were among the first of the Death Guard to be sighted again when they brought plague to the [[Agripinaa System]] in M35. The success of the ''Terminus Est'' in defeating the battlegroups sent against it had a major effect on the thinking of the [[Imperial Navy]]. In [[M36]] an [[Adeptus Mechanicus]] expeditionary force succeeded in finding schematics of its design on the perdita world of [[Barbarus]] and began building the Despoiler class.{{Cite thisFn|2}}

Little were they to know that the core architecture and design of the class’ warp shields hid a fundamental flaw. Only when in the following centuries the vessels of this class were either lost in the Warp or turned renegade did the realisation strike home. The ''Terminus Est'' and Typhus did not assume a central role in the [[Gothic War]]. A single sighting near [[Anvil 206]] was the only evidence of their presence. However, considering the later incidents traced back to Anvil 206 it is clear that a particular mission was accomplished.{{Cite thisFn|2}}

In M41 the ''Terminus Est'' is one of the oldest ships known to the Imperium, the power of Nurgle holding its ancient hull together while the most virulent plagues seethe through its dank corridors. The ''Terminus Est'' is a part of Nurgle’s realm given license to travel the stars, spreading death at the behest of its damned captain. There will be no rest for the Imperial Navy until it is finally hunted down and cleansed forever.{{Cite thisFn|2}}

The ''Terminus Est'' is surrounded by vast swarming clouds of the same Warp-spawned flies which buzz and howl through its interior, and which first transformed Typhus into the Host of the [[Destroyer Plague|Destroyer Hive]]. This miasma permeates outwards from the ship, through blisters, boils and fractures in its surface or through corroded, useless discharge tubes and weapon barrels.{{Cite thisFn|2}}

This miasma replaces the ship’s turrets, and works in exactly the same way as turrets against attack craft, but has no effect against torpedoes. The miasma is so thick that it obscures and distorts the shape of the ''Terminus Est''.{{Cite thisFn|2}}

Along either side of the ''Terminus Est'', row upon row of festering pustules, hives, boils and sores erupt outwards from the ship’s cankered skin. These growths cover the rusted remains of what was presumably once the ship’s main broadside batteries, growing in a diseased parody of these weapons like coral over rock. They seep and bloat, periodically erupting violently and hurling a mixture of corroded debris, ammunition and filth out into space.{{Cite thisFn|2}}
