War of the Beast - The Proletarian Crusade: The ensuing conflict took a turn for the worst, as the Imperium seemed to be beset on all sides from the massive Ork expansion that was now on a galactic scale. All corners of the Imperium, in every Segmentum, saw heavy fighting against the seemingly unstoppable tide of the The Beast's greenskin tide. Both Imperial worlds of Prandium and Quintarn in the Realm of Ultramar were invaded, forcing the Ultramarines and several of their Successor Chapters to take a defensive role. This left them unable to assist the rest of the Imperium. Meanwhile, the Iron Hands sent three whole companies to assist Terra, while their fellow First Founding Chapters, which included - the Salamanders, Space Wolves and Raven Guard - to become bogged down fighting their own separate campaigns against the forces of The Beast, leaving them unable to come to the aid of Terra as well. However, the heroic and noble Blood Angels achieved some small victory, successfully destroying an Ork Attack Moon in the Baal System. The expansion of the Ork invasion was such, that it even spread beyond the borders of the Imperium, as the greenskins assailed the Iron Warriors-held world of Klostra, located near the Maelstrom warp rift.Back on Terra, the arrival of the Ork Attack Moon caused widespread panic amongst the population. The Adeptus Arbites struggled to contain the massive waves of riots that erupted across the Throneworld and in the anarchy and chaos, thousands of innocents died. The High Lords themselves, were barricaded within the secure areas of the Imperial Palace to ensure their safety and security. To make matters worse, all contact was lost with the Martian Priesthood on Mars, as Fabricator-General Kubik refused to send aid to Terra.With the majority of Battlefleet Solar deployed elsewhere or destroyed during the Battle of Port Sanctus, Terra was now left virtually defenceless. This left Lansung disgraced, as the former Lord High Admiral fell out of favour and lost position within the Senatorum Imperialis. It was at this moment, that a desperate plan emerged, concocted by Juskina Tull, the Speaker for the Chartis Captains and Ecclesiarch Mesring of the Ecclesiarchy. They proposed to launch a "Proletarian Crusade" comprised of millions of Frateris Militia forces and Imperial civilian volunteers in support of remaining Astra Militarum regiments and Adeptus Arbites. Though many notable High Lords, including Vangorish, Veritus and Lansung condemned the plane as sheer madness, they were overruled by the ascendant Speaker for the Chartist Captain and Ecclesiarch.The commencement of this Crusade took place shortly after its announcement. Thousands of civilian voidcraft of all types, were launched towards the Ork Attack Moon in Terra's orbit. Ork fighters and boarding parties sustained heavy casualties as millions of Imperial crusaders, Astra Militarum troopers and Adeptus Arbites forces, launched their desperate attack upon the Attack Moon. Due to immense size of the makeshift fleet, the Imperials were able to punch through the Ork's defences, and successfully landed millions of troops upon the surface of the Attack Moon. They were even able to land a few hundred Leman Russ Tanks as well as a number of Chimeras and Hellhounds in support. They were soon engaged in a vicious battle with a large force of attacking greenskins. The Imperials were able to drive back the Orks through their sheer numbers and brutal close assault fighting. However, at their moment of triumph, the Imperial forces were utterly annihilated when the Orks manipulated the planetoid's surface, crushing the invading Imperial forces by enclosing mountains.Following the disaster of the Proletarian Crusade, the Throneworld faced destruction at the hands of the encroaching Orks. Seemingly out of options, an unforeseen event took place when a surviving Crusade vessel landed upon Terra's surface. Three Orks, including an "ambassador" emerged from within. The Imperials identified these Orks as an entirely new sub-set of advanced-evolved "Beast" Orks, similar to their infamous Warlord. The ambassador, identifying himself as Bezhrak, amazingly spoke Gothic and managed to arrange a meeting with the Senatorum Imperialis thanks to the efforts of Vangorich. The Ork ambassador demanded that Terra surrender or face inevitable death. Left speechless, the High Lords were unable to give the Ork ambassador any kind of coherent response. Disgusted by the humans' cowardice and apparent lack of resolve, the Ork ambassador took his leave and departed Terra. Just as the Crusade vessel departed and Aeldari vessel appeared over the Imperial Palace.
