Blood Angels - Trials of Sanguinius: After the Emperor oversaw the creation of the primarchs, the Ruinous Powers made off with the infant demi-gods still in their gestation capsules and carried them through the Warp. Unable to destroy the primarchs because of the powerful psychic and physical protections laid on them by the Emperor, the Daemonic powers nonetheless did their best to alter the Emperor's work to their own dark ends. Thus it was that even the best of the Emperor's creations became corrupted at the outset.The gestation pod that housed the infant Sanguinius came to rest upon the moon of Baal Secundus, at the place now known as Angel's Fall, which later grew into the moon's only major settlement. Few of the young primarchs who were spirited away from the Emperor on Terra through the Empyrean by unknown means found themselves in conditions that any might describe as fair, and yet even among their number Sanguinius was particularly ill-favoured by where fortune cast him.Though the Baal System had once been a thriving hub of Mankind's ancient interstellar empire, it had since been reduced to a sea of radiation-scorched ash and dust by its people's own folly during the Age of Strife. On the second moon, where the primarch Sanguinius was cast adrift, there eked out a fragile remnant of Humanity, a number of feral, warlike post-apocalyptic tribes that stalked the wastelands surviving on the plunder of war and what little could be foraged from the deserts.Sanguinius' earliest days were spent in the deep desert and of them little is known, for Sanguinius never spoke of them in later years. Doubtless he faced hardships that would have slain full grown men, slew the mutant creatures of the wasteland that even the desert tribes avoided and survived where the radiation unleashed by the atomic weapons used on the moon during Old Night would otherwise have cooked the flesh of mortals in solar minutes.It is not known how long Sanguinius' sojourns alone in the radioactive wastelands lasted, but by the time he was discovered by one of the many Human tribes of Baal Secundus he was a young boy, almost of age by the standards of the tribesmen. The young Sanguinius' life almost came to an end then and there, for great white wings, like those of a mythological angel, emerged from his back.Whether these wings were born of Baal's mutating influence upon his posthuman genome, an affect of his transport through the Warp or were part of the Emperor's intentional design is a secret known only to the Master of Mankind. Many among the tribesmen who found the primarch wanted to kill the child as just another mutant, though in all other ways he was as perfect a Human child as had ever been seen.Eventually innate compassion prevailed and the child was spared. Sanguinius was quick to adapt to his new life among the tribe, as were all his kind in similar circumstances, and his strength and resilience quickly earned him a place within the ranks of the tribe that had found him, known, as were all the tribes of Baal, simply as "The People of the Blood" or "The Blood."The young Sanguinius was a prodigy -- he grew quickly and learned everything his adoptive parents could teach him. It is said that even when still a child he slew a giant fire scorpion with his bare hands, and that he never once showed fear at the colossal beast's onset.As Sanguinius grew his wings grew also, becoming mighty pinions that could bear him aloft upon the desert air. He could walk without a rad-suit in the most poisonous of Baal Secundus' deserts, and could shatter massive boulders with a single blow of his outstretched hand. In the use of all weapons he soon excelled his teachers.When a wandering band of feral mutants surprised the tribe, Sanguinius slew them all, although they numbered over a hundred. This was the first time the members of The Blood had ever seen him truly angry, for he felt his comrades' lives were in danger. When the blood-rage overtook him, Sanguinius was indeed terrible to behold -- his mighty primarch powers awoke to fullness and a nimbus of light played about his head.He grew to manhood rapidly, troubled all the while by dreams and ill-portents of death and blood, and the arrival of a grim and unknown king to Baal from other worlds. He fought against the mutated sub-Human creatures that prowled the deep desert and the raiders of other tribes with the same single-minded focus that he gave to his loyalty to his new people of The Blood. Yet, unlike so many of the other primarchs, there was no long war of planetary unification undertaken on Baal Secundus, no glorious campaign of conquest to prove the young demi-god's worth.The legend of the winged warrior had spread far across Baal, stories of a warrior tall, fair and much unlike the stunted and radiation-scarred people of the moon. Ferocious in war and wise in peace, he seemed to be a vision of past glories come once again to Baal, a promise for the future that had all but been forgotten among The Blood. Despite any denials on the part of the primarch of his divinity, he became as a god to his foster people, and warriors from across the wide desert came to fight at his side. Under his guidance they rolled back the mutant tide. For a time Mankind had a respite on the moon of Baal Secundus.Within the span of a few short local Baalite years, each an endless scorching summer, a vast host had gathered at the Great Angel's side, to learn from his words and to shelter beneath his wings. He had become the master of his world not by force or conquest, but simply by the acclamation of a desperate people.
