Iron Warriors - Lord of Iron: When the twenty infant primarchs were scattered across the galaxy from Terra still in their gestation pods by the power of the Chaos Gods, the young child who would become known as Perturabo was discovered on the world of Olympia, a mountainous planet divided into constantly warring Human city-states.The infant was found by the servants of Dammekos, the so-called "Tyrant of Lochos," while climbing the sheer cliffs below the city-state of Lochos. The city guard brought the child before the Tyrant. Intrigued by this odd boy who showed such skill and talent for an unknown orphan, Dammekos adopted him into his family and raised him as his own.Perturabo never trusted the Olympians and, although Dammekos took time and trouble to win the trust and affection of the boy, Perturabo never responded to his foster father with any warmth. Many saw him as a cold youth, dark and melancholy, but with a mind as sharp as a razor. Despite his aloof demeanour, Perturabo learned from the culture in which he found himself the arts of the siege, for Olympia's warring city-states afforded plenty of opportunity to study both the theory and the practice of this branch of warfare.Such evidence that remains of the recovery of Perturabo and his installation in the forces of the Great Crusade indicates that the process occurred swiftly, and with immediate acceptance on Perturabo's part, in marked contrast to several other primarchs. It is likely that the tyrant Dammekos was more than willing to bring Olympia into the Imperium's fold, as its satrap, and the price of voluntarily releasing Perturabo from his service was but a small due to pay.Perturabo for his part, it is believed, had already reasoned out his true nature, at least in abstract, as an artificial posthuman being, and indeed expected his creator to one day be revealed to him, even though the particulars no doubt remained a mystery until the Emperor Himself appeared in orbit with his fleet in 849.M30.It was remarked upon at the time of his early reception in a number of sources, just what a ravenous mind the new-found Primarch possessed. While all of the Emperor's post-human sons displayed an intellect and capacity to absorb and adapt to new knowledge that surpassed that of an unmodified human, Perturabo's capacity for learning was truly incredible, and it swiftly came to be said that of all of the Emperor's sons, he was the most gifted in terms of raw scientific and technical intelligence.Much of this sagacity was turned inwards, however, and Perturabo was from the outset a distant, calculating mastermind who cared little for the society of others, nor readily deigned to explain his actions or intentions to those around him, even to his fellow Primarchs upon meeting them, who he was cold and guarded against to the point of bristling indifference.To the Emperor such personality foibles mattered little, and in Perturabo He found a new weapon for the arsenal of the Great Crusade, a warlord and general whose savage might was only eclipsed by his razor-keen intellect. To Perturabo each battle and each campaign was no more than a problem to be objectified, deconstructed and overcome, and it would not be long before the first of Mankind's foes would feel the terrible power of this murderous mind at work.
