Editing Medhammer 40,000 Primarchs (section)

==Rogal Dorn==
Disgraced as the Emperor's Praetor, Humiliated by Alpharius and Perturabo, and Abandoned by his own Legion, Rogal Dorn, Former Praetor of Terra, and Great Architect of The Imperial Palace has retreated to his home in the Inwit sector, and there he is building. Those few Imperial Fists (now called The Hands of Dorn) who have remained loyal are his master builders, serving to transform the Entire Inwit Segmentum into a Citadel. Few of his brothers know why, or what he is building for, and most have assumed their brother mad, for surely nothing exists to be as terrible to need a fortress this strong?

===During The Great Treachery===
Perturabo is able to goad Dorn and his fists into a Trap on Olympia, which Perturabo has transformed into a massive fortification he calls the Iron Cage.The LL Iron Cage is less Grimdark than its Vanilla hammer version, its more like a standard seige (Though Perturabo now also employs warp magic into his fortifications, making it a trippy seige as well). Its significantly less devastating than on the Imperial Fists, however it does take a really long time to seige. Long enough for Dorn to be away at his post on Terra for Alpharius to sneak in, destroy half the Imperial Palace (and about half of the Custodes, and a good chunk of what was Asia and the Pacific) on Terra with an Archeotech Bomb, Kill Malcador the Sigilite, Mortally Wound the Emperor and Steal the Emperor's Right Hand and Heart as a Tribute to Tzeentch. Once he finally cracked Perturabo's Seige Perturabo was no where to be found. Perturabo then Blew up the planet of Olympia as an offering to The Prince of Pleasure for Demonhood.

The Imperial Fists, already exhausted from the endless months of intense seiging and warfare from multiple fronts, suddenly had less that a few hours to regroup, salvage their equipment, and make it to the transport ships (they were unable to teleport). Dorn and his legion barely escaped. And of the 30% of his legion he lost to the Seige of the Iron Cage, nearly two thirds came from those who were unable to escape, their souls now captives to the Prince of Pleasure as a gift from his favorite champion.

===After The Great Treachery===
His legion was mostly intact, but he took the injuries his Father and Terra sustained very personally. The fact that his father was only wounded, and that there was only a continent sized crater on Earth did little to lift up his spirits. Dorn resigned from his Position as The Emperor's Praetorian, and wandered the galaxy. At some point in his self-imposed exile of he stumbled upon rumors of Hive Fleet Tiamet. He and his men followed through and in M33 he encountered Ziaphoria's Tower. Ordering an excavation of the tower. Through this Dorn has learned the awful truth of what is coming, and that Humanity is not prepared. Perturabo's words ringed in his soul and he suddenly realized his true calling. He saw an entity who, like him, had no concept of surrender, no notion of the cost of war, no instinct except endurence and adaptability. Discovering new found purpose he returned to Terra and formally requested that the Segmentum Tempestus be handed over to him. The Sector, which was divided among the already overworked brothers, were more than happy to have their brother back and active in Imperial affairs again. They readily granted it to him. Now in control of the Segmentum, He immediately set to work. All local leaders who opposed his rule or designs were expelled (this now includes the nomadic fleet Tallarn, who opposed the engineering of their home system). All resources in the Segmentum, be it human, material or spiritual, exists for the fortifications of the Segmentum. Planets, drained of their mantle for Ore, stars have gone dark from Dyson spheres, asteroid fields lay vacant, gas giants Syphoned to their core. At the Center of it all lay Inwit, once an ice world now a Fortress world three times the size of its old planet, surrounded by rings and floating fortresses.

===Abandonment by his Legion===
While Russ lost his legion to the madness of chaos, Dorn lost his to his own all consuming obsession. Sigismund, representing those Fists who wished the Legion Returned to their founding purpose of Great Crusades and glorious conquests confronted Dorn. Dorn, while furious, let them go. The Few that remained (about 4 chapters worth) renamed themselves the Hands of Dorn. Because of his Legion Deserting him, Dorn has come to rely more on the Men and Women of The Segmentum, in particular the "Crenellations of Krieg," who are his steadfast fortress defenders. The Entire Segmentum is hammered into the image of Dorn. Stoic, utilitarian, obstinate, and ever resilient. And when The Hive Fleets dig begin to arrive in the Segmentum. Dorn and his Troops stand ready.
