Blood Angels - Teghar Campaign: Sanguinius was to learn the ways of war at the side of Horus himself, accompanying that Primarch and his Luna Wolves, to see how war was waged among the stars and to understand the functions of the vast Imperium that the Emperor was building. As Sanguinius forged a bond of trust with his mentor and brother, the IXth Legion was finally summoned to attend upon their new and true master.Gathered from distant war zones across the galaxy, it took many solar months for each disparate band of the IXth Legion to be found and recalled. It would be two standard years and four solar months before the gathering was complete, and on the storm-wracked world of Teghar, an army of grim killers with the faces of angels assembled, eagerly awaiting a new slaughter of which to partake.The captains of the Revenant Legion, the Great Crusades' blood-soaked angels, gathered as Stormbird transports bearing the mark of the Luna Wolves descended from orbit. From within came a troop of warriors clad in the white of Horus' own Legion, yet the one at their head was not Horus, though by his stature he was a true son of the Emperor and one of His Primarchs.Great white wings unfolded and Sanguinius revealed himself to his gene-sons, his sculpted features the very image of those that thronged about him. Sanguinius beheld the gathered warriors of the IXth each bearing the scars of unrelenting battle both on their proud faces and in the dark recesses of their spirits.These were not men to be impressed by the pomp and ceremony of his escort, nor by simple strength of arms. The winged Primarch, amid the rain and storms of that far world, took a knee before the rough-cast killers and scarred blood-drinkers and, rather than demand their allegiance, he offered them his own.The warriors who had offered up everything to the new Imperium and in return been granted only scorn and mistrust, were now offered a Primarch's loyalty, given freely and without reservation. Sanguinius had won their devotion with his actions, and to seal them to him he led the assembled Legion on their first campaign together, standing in the front lines of battle where his valour spoke for the sincerity of his pledge.The storm-wracked fifth world of the Teghar System, Teghar Pentaurus, was the stage upon which Sanguinius fought for the loyalty of his Legion. There he gave of his blood in the maelstrom of combat and came to understand the true nature of his sons. Sanguinius witnessed the bloodlust and fey hunger that ran through his Legion's core and recognised it as his own darkness.The Abhuman hordes of Teghar and their bestial thralls fell before the IXth Legion like wheat before a scythe, Sanguinius himself claiming the pelt of a dire carnodon as a trophy of battle and a symbol of the pact he had formed with his sons. In the gore-spattered aftermath of the campaign, Sanguinius saw one possible future, a crimson future of war eternal where his sons would truly become monsters, the playthings of a dark and terrible fury. Yet, the winged Primarch did not despair.Even in the heat of battle, there remained in the warriors of the IXth Legion a spark of nobility, the still-warm ashes of their martial pride and determination. They fought to grasp the fickle favour of victory, not simply for slaughter, and held to their own codes of honour with an iron will. These would be his weapons in the battle for the IXth Legion's soul, the tools with which he would raise them up.The winged Primarch knew full well that no future was absolute, no dark fate beyond hope of repair, and with the end of the battle for Teghar he declared, "even though a darkness hangs over them, a future soaked in blood and horror, they are angels yet. Angels of Blood." The IXth Legion, the Revenant Legion, had been reborn and earned a new name: the Blood Angels.
