Jaghatai Khan - Second Battle of Prospero: The Second Battle of Prospero did not match the horror of the first, for the Death Guard had come to hopefully oversee the incorporation of an ally, not embark upon a protracted void conflict. The two fleets grappled together as they pulled away from Prospero, locked in a web of broadsides and attack runs.Under Mortarion's leadership, the smaller XIVth Legion forces rallied enough to withdraw from the system intact, but they could match neither the speed nor the firepower of the reunited White Scars. The battle moved steadily out of the system until Mortarion finally gave the order to disengage and make for the Mandeville jump-points.Leaving a trail of fire and plasma in their wake, the Death Guard entered the Warp, abandoning local space to the control of Jaghatai Khan. With the enemy driven from Prospero, the Vth Legion halted its pursuit. The fleet mustered once more, holding position in loose formation, just as it had done at Chondax. Some ships still ran with dissension, and the process of restoring order was neither quick nor without violence. The Khan visited every Battleship in person, stamping out the last traces of rebellion where he found them.Blood had been shed on many vessels, and some had been commandeered entirely by White Scars Warrior Lodge members still hoping to sway the Legion to the cause of Horus. Some took their own lives rather than endure the shame of surrender, though most recognised the authority of the Khagan and offered up their blades in contrition.A few smaller vessels never made it to the muster, either destroyed by the Death Guard during the engagement or disappearing quietly, presumed unwilling to accept the rejection of their planned accord with the Traitors. The seeds planted by the lodge were set deep, and not all of their growths were capable of being removed.The wounded Hasik Noyan-Khan remained on the Swordstorm throughout the engagement. Only when Mortarion had been banished did Qin Xa come for him, removing his weapons and armour and escorting him to the confinement chambers. Hasik did not resist.His face gave away the soul of a man destroyed. Others went with him into confinement, among them Goghal, Hibou and Torghun Khan. There they awaited judgement, guarded by the Khagan's own retinue. No precedent existed in the Vth Legion for their actions, though under the old law of the Altak steppes on Chogoris, the crime of treachery and betrayal had only one punishment -- death.The Thousand Sons Astartes Arvida remained with the White Scars Legion and was given quarters on board the Swordstorm. His health had been ravaged by the long sojourn on a dying world, and it took solar days for him to recover enough to speak of what he had seen. The Stormseer, Yesugei Targetei, had fought his way halfway across the galaxy aboard the frigate Sickle Moon in order to reunite with the Khan, and both the zadyin arga and Arvida spent many hours together after that, though what they discussed was not revealed to any but the Khan.It was known Yesugei asked after the fate of his friend Ahzek Ahriman, whom he had hoped to see again, but Arvida could give him no guidance. The Stormseer was forced to conclude that either Ahriman had been killed by the Space Wolves or had escaped into the Warp along with his master Magnus. In either case it seemed most likely that they would never meet again. Of the many links that had once existed between the White Scars and the Thousand Sons, only Arvida remained.As for the Khan himself, once the violence of restoration had ebbed, he retreated to his chambers on the flagship and took counsel on the Legion's next move. Only Qin Xa and Yesugei stayed with him during that time, though it was known that a kurultai -- a summit of the Legion's khans -- would be convened to purge any remaining bad blood. It became quickly evident that the Warrior Lodge faction of the Vth Legion had not truly understood what they had been working towards, for the Horus they venerated no longer existed.The knowledge gleaned from Magnus needed to be propagated swiftly, ending the long period of uncertainty that had blighted the White Scars Legion. Such was the way of the old plains: grievances would be heard, penance would be meted, bonds restored. No time was set for the gathering, but all the Brotherhood khans knew it would be soon.Now that the true shape of the treachery against the Imperium was known, it would not be long before the Brotherhoods were ordered to war, unified once more and thirsting for vengeance. Until then, there was nothing to do but prepare, restore, and hope that the wounds of the Legion would heal before they faced the Traitors once more.
