The edge of Ruin

The WaRmasTeR’s Rebellion

The End of Empire

A Betrayal Long in the Making

The edge of Ruin ‘All empires must fall to ruin and despair, just as mine has done. Yet, when your own wars are won and you stand amid your triumphs, remember that the fate which has befallen me will in turn be your own. Look for me then, for at the edge of ruin I shall return to remind you of the fate of empires.’ Apocryphal, attributed to the Unspeakable King on the eve of his defeat during Old Night 1 The WaRmasTeR’s Rebellion In the fifth year of the 31st Millennium Horus Lupercal, Warmaster, favoured son of the Emperor and hero of the Great Crusade, plunged the Imperium of Mankind into a war from which it would never truly recover. Amid the shattered cities of the lonely and distant world ofIsstvan III, he set the warriors of the Legiones Astartes against their brothers, raising the banner of rebellion and drowned his oaths of loyalty in blood. Those of his brothers that held true to their oaths would come to face him at Isstvan V, only to find that Horus had laid well his plans oftreason. Fully half of the Emperor’s Primarchs and Space Marine Legions were already secretly sworn to Horus’ side and they turned their guns upon their kin with abandon, leaving the pride of the Imperium broken upon the black sands of that once insignificant world. Worse yet, the Primarch Ferrus Manus would be slain outright, his head made a trophy for the traitor Warmaster, and Corvus Corax and Vulkan lost to their sons. At a stroke Horus had shattered the Legions that had all but conquered the galaxy, cleaved apart the heart of the Imperium and laid clear his path to the throne. That would be his ultimate goal, Terra, the Throne World of the Imperium, that he might cast down his own father and take His place. In his way stood Rogal Dornand the few remaining steadfast armies of the Imperium, the other loyal Primarchs scattered to the far corners ofthe Imperium and unable to come to the Emperor’s aid. A narrow belt of worlds held the main route from the far north and Isstvan to Terra, the fortresses of Paramar, Beta-Garmon and Lorin Alpha. Here would be fought a desperate holding action, Rogal Dorn spending all his resources and committing all those warriors at his command to slowing the advance of the Traitor hordes. For two long years they would hold the line, keeping Horus at bay at the cost of millions of lives ina series of bitter sieges and desperate battles, a conflict that would spawn legends to last 10,000 years. Yet even as they fought, the flame of rebellion spread and took root in all the worlds ofthe wider Imperium, the war no longer a simple matter of overthrowing Terra and claiming the throne, but a sprawling morass of old grudges and feudsnow ignited into open battle. The End of Empire The short and decisive war that Horus had planned for had not come to pass, his triumphant advance on Terra stymied in years of grinding conflict, all while the Imperium bled and suffered. Those few loyal Legions that retained the force of arms to resist the Traitors in open war were penned in small enclaves, unable to halt the chaos that now spread to engulf the realm they had fought to create. The Imperial Fists were arrayed defiantly about Terra, their strength the only remaining bar to the Warmaster’s onslaught. Distant Ultramar, the rich domain of the Ultramarines where the largest army in all the Imperium waited for the call to arms, was in ruins and cut off from all contact with Terra, which they presumed had now fallen to the enemy. Even the fortress system of Baal and the proud warriors of the Blood Angels sat within a cage of the Warmaster’s making, paralysed by the absence of their master and inundated with the broken survivors ofIsstvan V and the terrible doubt those broken warriors carried with them. Yet, despite their hardships these disparate forces had managed to slow the Traitors with their stubborn refusal to fall before the might of their treasonous brothers, keeping alive the embers of the Loyalist cause a
