M41: Purging of Contqual — The Iron Hands eliminated Chaos forces from twelve planets in the Contqual subsector. [4] At the height of the battle Chief Librarian Telach sacrificed himself to stop Julius Kaesoron, former First Captain of the Emperor's Children, now a Daemon Prince of Slaanesh. [53g]

Before the Heresy, Fulgrim was a warrior that enjoyed the finer arts of civilisation and culture of his people such as art, music and celebration. He believed that there was little point in conquering the galaxy if they did not indulge in these civilised traits. Fulgrim himself also engaged in the arts and created marble statues of his two three first captains though he felt that his work was not perfect. [Needs Citation] Fulgrim was anxious to make his contribution to the Great Crusade, but the comparatively small size of his Legion meant that the Emperor's Children were placed under the command of Horus and his Luna Wolves. Horus and Fulgrim grew close to one another while pacifying the Eastern Fringe. Eventually, swelled by recruits from both Chemos and Terra, Fulgrim was soon able to lead a crusade of his own, bringing countless worlds into the light of the Imperium. [1] Fulgrim sought perfection and spectacle in these campaigns, as demonstrated when he took the world of Byzas with only seven men, despite nearly dying in the process. [12] Fulgrim also established a close friendship with his brother Ferrus Manus, who also attempted to purge imperfection from himself. Ferrus and Fulgrim eventually came to each try to build the perfect weapon, resulting in Fulgrim crafting Forgebreaker and Ferrus Fireblade. The two exchanged weapons and they became synonymous with their respective Primarch's thereafter. [2] In the later stages of the Crusade the Emperor's Children soon made a name for themselves during the Crusade, battling fearsome enemies such as the Megarachnids and Diasporex. [Needs Citation] Because of this compulsive drive, many of the Chapter's leaders are entombed within the form of a Dreadnought. These form the Chapter council, the so-called " Iron Council," for the Iron Hands have no individual Chapter Master. Each company is an all-but independent body called a "clan company," which maintains its own mobile fortress-monastery that trawls the endless wastes of Medusa guarding against weakness in the people and recruiting the strongest encountered into its ranks. Destruction of the Tomb World Shemnoch — With the aid of the Brazen Claws the Iron Hands invade Shemnoch and eliminate Shemnoch's Necron Dynasty [Needs Citation]The following information is not to be regarded as officially sanctioned and/ or is not written from an in-universe point of view. A detailed explanation of the term "Trivia" as used in the Lexicanum can be found here. Captive phase-gates, subatomic infusers and temporal loop shrouds can all exhibit similar effects to nanoscarab swarms. To a Necron Overlord, how these abilities work is of little concern, as long as they do. The war machines of the Necrons are things of impossible science and countless arcane technologies. To the young species of the galaxy, the energies and weaponry of these strange engines of destruction are more akin to magic than anything recognisable as physical engineering.

When the Horus Heresy first erupted and plunged the newborn Imperium into a galaxy-wide civil war, the Iron Hands Legion was too far from Terra to intervene directly in the climactic battle of the conflict. Their Primarch Ferrus Manus was enraged by the weakness of those Legions who fell to Chaos, particularly with his closest brother amongst the primarchs, Fulgrim of the Emperor's Children, and by his own inability to face the Traitors. Ferrus Manus gathered together his most Veteran Astartes and departed for the Isstvan System. The Iron Hands are a Loyalist Space Marine Chapter and one of the original First Founding Space Marine Legions created from the gene-seed of their martyred primarch, Ferrus Manus.In his spartan quarters, Fulgrim was faced by armoured warriors from the stars. Their faces bore the scars of many battles, and from their shoulders hung scrolls listing their achievements. Their armour and weapons were finely-worked, and their banners and pennants were works of art. Fulgrim recognised that these men were not merely advanced, but civilised — his lost brothers from the stars had preserved the arts he had longed to return to Chemos. From the midst of these warriors stepped their leader, the Emperor of Humanity. Fulgrim surveyed him and, without a word, knelt and offered his sword. On that day Fulgrim swore to serve the Imperium with all his heart. From the Emperor, Fulgrim learned of the distant world of Terra, of the Great Crusade to reclaim the sundered galaxy, and of his own origins. It is unknown when exactly this event occurred; however, it is recorded that the construction of a starship for the Primarch of the III Legion was completed around 160 years before the beginning of the Horus Heresy.
