Great Unclean One - Notable Great Unclean Ones: Botchulaz - Botchulaz was trapped by the Aeldari within the psychic construct known as the Black Pyramid on the Imperial Hive World of Aerius. The key to this prison was the artefact known as the Talisman of Lykos, which was split into three pieces, one of which was found on the Space Wolves' homeworld of Fenris, another on the world of Galt and the third in the vaults of the Inquisition. In the late 41st Millennium, Botchulaz manipulated several servants of the Imperium into reuniting the pieces of the talisman and freeing him from his prison, but these Imperial heroes were able to salvage the situation in time to re-imprison the Greater Daemon at the cost of many Imperial lives.Bolothrax - In 529.M33 three Imperial sectors are overrun by a vast army of the Immaterium referred fearfully to as the "Daemon Tide." Deploying into the Daemons' path, five knightly houses -- led by the renowned Nobles of House Terryn -- form an adamant bastion to halt the rampage. Using swift-loping packs of Armiger Helverins and Warglaives, High Queen Desmadara Terryn channels the Daemons through the shattered valleys of Godsmote. As the Warp-born creatures spill onto the Hollow Plain they are subjected to thunderous bombardment by two dozen Knights Castellan. The Daemons' casualties are phenomenal, yet with no concept of fear they surge onward to exact revenge. Over six hundred Questoris-class Knights storm out to meet them, enduring barrages of sorcery, flame and filth that send towering Knight suits toppling in ruin. With Queen Desmadara and her Exalted Court at the lance-point, the Knights slam into the still-vast daemonic horde. They carve a path of annihilation to its heart, the ground shaking beneath their tread, unclean ichor drenching their legs. Though empyric fiends and coruscating Warp energies tear down one Knight after another, their momentum is unstoppable. At last, with Reaper Chainswords howling and Thunderstrike Gauntlets crackling, the Exalted Courts of three knightly houses engage the masters of the Daemon Tide. The battle that follows is so grandiose and cataclysmic that it spawns a hundred songs, tales and tapestries. Several heroic Knights are slain by the enormous Great Unclean One Bolothrax, before the Knights Valiant known as Master of Iron and Fellbreaker successfully pinion the foul abomination with their Thundercoil Harpoons. With their quarry unable to move, the Knights hack the mighty daemon apart. Bolothrax's banishment spells the end for the Daemon Tide, though they wreak much more destruction before they finally fade back into the Warp. It is on that day that Bolothrax's unending grudge against House Terryn and all its descendants is born. Later, in the years after the opening of the Great Rift, Bolothrax would gain his revenge. Amidst the swirling fury of the Damocles Gulf, High King Tybalt leads the Knights of House Terryn in their latest push against the T'au invaders. They strike at the recently reclaimed T'au colony world of Shans'et, formerly an Imperial-held planet known as Gossamehr. Initially, the Terryn offensive progresses well. The Knights are supported by a force of Raven Guard Space Marines, who scout ahead of their advance and repeatedly negate the xenos enemy's rapid-manoeuvre tactics. The battle takes an unexpected turn, however, as the skies curdle into matted filth and black rain falls, rotting all that it touches. From the sucking morass rise the Daemons of Nurgle, led by the bloated abomination that is Bolothrax the Great Unclean One. In the vicious conflict that follows, House Terryn sustains terrible losses, while the vengeful Bolothrax wounds High King Tybalt sorely and fells the Knights of three of his closest blood relatives. It is only when the Raven Guard lure the T'au forces into contact with the daemonic host that Tybalt's Exalted Court are able to spearhead a breakout. The mauled Imperial forces stage a fighting retreat to their extraction point, battling droning plague creatures all the way. They leave Shans'et to the frustrated Daemons, who waste no time in making the T'au suffer.Gul'gulm'ga'tol - During the Battle of Hamagora in the early 42nd Millennium, the 2nd Company of the Scythes of the Emperor, newly reinforced with Primaris Astartes Battle-Brothers in the wake of the reinforcements brought by the Indomitus Crusade, found itself under siege upon the Hive World of Hamagora, assailed by an endless swarm of Nurgle Daemons. Intercessor Squads established a punishing series of kill-zones amongst the ruins of hive city Agrippa, yet for every daemon they slew, two more emerged from the dank tunnels of the undercity, and their casualties began to mount. Operating in total secrecy, Strike Force Harbinger of the Grey Knights' 5th Brotherhood teleported into the sub-city. Their quarry was the Great Unclean One Gul'gulm'ga'tol, who had turned Agrippa's sprawling sewage works into his personal baths -- hordes of putrid Daemons crawled endlessly forth from the morass of rancid gruel. After a bloody battle, the strike team sent Gul'gulm'ga'tol screaming back into the Warp. Hamagora was saved, though the Scythes never discovered how.Ku'gath the Plaguefather - Ku'gath is driven by an eternal quest to discover the most perfect pestilence that has ever existed.Rotigus - As the Death Guard's siege of the Imperial Hive World of Nebbus reached its seventh standard year in the early 42nd Millennium, Mortarion's Death Guard Sorcerers summoned an ancient evil to aid them. The strange Great Unclean One known as Rotigus joined the fight, bringing with him his appalling aura of infernal fecundity. Protein vats in the hives overflowed as the flesh-broth within them grew at an unstoppable pace, burying entire levels under flabby drifts of bloated meat. Vermin of every sort entered frenzied cycles of birth and death, the Imperial defenders finding themselves overwhelmed by tides of sump-rats, infestations of grizzleworms and million-strong swarms of ravenous ripper jacks. Worst of all was the Deluge of Nurgle, an endless storm of putrid filth-water that seethed with infectious, bacterial life. Soon enough Nebbus' arid plains became quagmires, then stinking oceans that rose higher and higher. The corpse-choked hive cities flooded from the roots upward, their last garrisons fleeing ever higher in search of a salvation that did not exist. Blessed beyond endurance by the plentiful generosity of Rotigus and his Daemons, methodically cut to pieces by the thundering guns of the Death Guard, it was almost a mercy when the last of Nebbus' defenders met their grisly deaths and the world was claimed for the Plague God.Scabeiathrax the Bloated - Also known as Papa G'aap, Lord of the Blighted Pit, Maggotspore, and the Wind of Nurgle, Scabeiathrax was most recently summoned into the mortal realm in 830.M41 by the Forces of Chaos infesting the world of Vraks Prime during the grinding military campaign recorded in Imperial databases as the Siege of Vraks.Septicus Seven - Septicus Seven was the Great Unclean One who commanded the Septicus Legion and was the second in command of the Greater Daemon Ku'Gath within Nurgle's elite daemonic Plague Guard. Septicus often carried with him the glistening stomach sac of some unfortunate creature with protruding hollow antlers, on which he played music as if it was a macabre bagpipe, summoning such terrible sounds that it exasperated even his fellow Daemons. During the later years of the Plague Wars, Septicus aided the Plague Guard in claiming the Garden World of Iax in the Realm of Ultramar for Nurgle. The Plague Guard then invaded Parmenio and later clashed with the Imperial forces led by the Lord Commander of the Imperium, Roboute Guilliman. During the battle, Septicus fought Guilliman, but was defeated, and his essence banished back into the Warp by the Ultramarines Primarch with the Sword of the Emperor. Though Septicus' essence was supposedly annihilated by the use of this potent Imperial artefact, as an extension of Nurgle's own consciousness, it was still possible for him to be resurrected. His ultimate fate is not fully known.Slogoth Poxbelly - Slogoth led the Plague Armies of Nurglite Daemons against the Fortress World of Cadia during the climax of Abaddon the Despoiler's 13th Black Crusade in 999.M41.Thing in the Walls - At some point during the Age of Apostasy in the 36th Millennium this Great Unclean One assaulted the mobile fortress-monastery Martyr in the Caligari Sector with a warband comprised of Nurglite Chaos Cultists, Plague Marines, and Plaguebearers. Over the next five thousand standard years the Martyr would slowly be converted into a Daemonship, but quickly caught the attention of the Inquisition upon reemerging in the sector from the Warp. Shortly before the conversion was complete an Inquisitor battled the Daemon, weakening it enough for an alpha-grade Pariah to completely destroy it.Ulkair - Ulkair manifested on the world of Aurelia in the 40th Millennium when a Warp Storm engulfed that planet, but he was defeated by the Blood Ravens Space Marine and Librarian named Azariah Kyras. But Aurelia was consumed by a Warp Storm and over the course of their mutual imprisonment Ulkair corrupted Kyras to Chaos, ultimately returning him to realspace to reunite with his Chapter and begin the process of corrupting the Blood Ravens to the service of the Ruinous Powers and heralding the return of Ulkair himself. Ulkair's plans were ultimately disrupted only through the heroism of Captain Gabriel Angelos and his fellow Blood Ravens Loyalists.
