Third War for Armageddon - Reconstruction of Armageddon: Following Ghazghkull's first invasion of Armageddon, a long investigation of the planet's readiness and defences was begun in 948.M41. In light of the strategic value of Armageddon to the Imperium, extensive works were ordered by the Adeptus Terra to secure the Armageddon System against any future attacks. The Imperial Navy's Sector Command was transferred to the Armageddon System and the naval facility of Saint Jowen's Dock was rebuilt and expanded to accommodate all classes of Imperial Navy warships. Three permanently-manned monitoring stations were established in the outer reaches of the star system, named after three of the greatest heroes of the Second War for Armageddon: Mannheim, Dante and Yarrick. Ground-based and orbital defences were rebuilt and heavily reinforced, gravitic minefields were seeded throughout the star system and a substantial increase in the numbers of sublight system defence ships and monitors was ordered.On Armageddon itself, the long process of reconstructing the hive cities destroyed by Ghazghkull's first invasion was begun. This was a process that was still ongoing over fifty Terran years later. In part, the slowness of reconstruction was caused by the increased number of Planetary Defence Force (PDF) regiments that were raised over this period, despite a lowering of Armageddon's tithe of regiments destined for the Astra Militarum.A military council was appointed by the Administratum to rule over Armageddon and was made up of high-ranking officials of the Imperial Guard, the Imperial Navy, the Departmento Munitorum, the Adeptus Mechanicus, the Ecclesiarchy and the Governor of each of the major hive cities on Armageddon. The council was led by General Kurov of the Imperial Guard, a respected veteran of the Bakkus Crusade.From 949.M41 to 978.M41, General Kurov coordinated a series of xenocidal campaigns conducted throughout the equatorial jungles between Armageddon Prime and Secundus and on the frozen planet of Chosin to eliminate feral Ork infestations which had sprung up in the aftermath of Ghazghkull's invasion. Fifty standard years passed and Armageddon slowly rose from the ashes, its defences stronger and more powerful than ever before. Still, it would not prove to be enough to face the green storm that was coming.The first sign of that coming conflagration was a series of Ork attacks on the star systems surrounding Armageddon and other Imperial worlds nearby. First, the nearby world of Minerva suffered from the depredations of Ork pirates, then the Agri-World of Ruis was likewise assailed by Greenskins. Over a period of solar months, in spite of the heroic efforts of the Imperial Navy, the number of Imperial merchant starships reaching Armageddon was cut in half. Someone seemed to understand that the Imperial forces in the sector were bound by the need to guard the Armageddon System and were not free to patrol the rest of the sector as freely as they normally would.Almost immediately, the Ork pirate raids grew into assaults on Imperial outposts and then into attacks against lightly-held Imperial colonies. Soon, the first full-scale planetary invasions began. Two dozen Imperial worlds came under attack from Orks in as many hours and the Astropaths of Armageddon received constant reports of yet more Ork invasions and atrocities. Every consultation of the Emperor's Tarot prophesied only enormous amounts of bloodshed to come and the sign of the Beast Resurgent.Rumours spread that Ghazghkull was returning to have his vengeance and soon even the most obstinate Administratum adept could no longer deny that an Ork WAAAGH! of gargantuan proportions was engulfing the entire Armageddon Sector of the Segmentum Solar. After the Imperial Navy's Task Force Trajan was presumed lost battling the Orks in the Desdena System, General Kurov sent an astropathic call for assistance to nearby Astra Militarum regiments and Space Marine Chapters to come to the defence of Armageddon once more.
