Third War for Armageddon - The Orks Regroup: Ghazghkull had not been an idle Ork following his defeat in the Second War for Armageddon. Retiring to his stronghold in a network of Ork-controlled star systems in the Golgotha Sector, he carried on with the master plan that had been divinely revealed to him by the Ork gods Gork and Mork solar decades before. If the Imperium had made one terrible mistake following the Second War for Armageddon it was to believe that Ghazghkull had actually been defeated.In truth, what the Ork gods had revealed to the Warboss, or at least what he said they revealed, was that in order to truly destroy one's foe, you first had to learn all about him. For Ghazghkull, the Second War had simply been a way to learn how the Imperium would react and defend against a major Ork planetary invasion. In effect, Ghazghkull believed that the first invasion had been nothing more than a test of the Imperium of Man's defences.In the five solar decades that followed the Second War for Armageddon, Ghazghkull carried on uninterrupted with his divinely-inspired plan. Having learnt all he needed to know about Imperial tactics and strategy, he began developing the tactics that he felt would lead to his enemies' ultimate defeat. As he did not want to draw attention to himself, these "experiments" were carried out on a much smaller stage than the invasion of Armageddon. From 945 until 959.M41, the Imperium received numerous reports of small Ork raids and attacks against Imperial bases and outposts that were led by Ghazghkull Thraka personally.In 962.M41, an Imperial military base on the world of Buca III was destroyed by missiles fired from an Ork base hidden within an asteroid. The asteroid entered the star system from deep space and bypassed all the Imperial sensors because of its seemingly inert nature before unleashing its potent missiles at the unsuspecting outpost.In 972.M41, the Imperial Agri-world of Chigon 17 was overrun by a huge force of Orks also allegedly under Warboss Ghazghkull's direct command. Despite the fact that Chigon's Imperial Guard defenders were equipped with tanks and other armoured vehicles, they were decisively beaten by the Orks in a lengthy guerilla campaign which rendered the powerful but static Imperial defences wholly useless.In 986.M41 the Imperial Navy battlecruiser Radiant Way and its escorts were lost with all hands in an attack by Ork pirates, again led by Ghazghkull. The Imperium responded in force but discovered that all signs of the ork presence had simply disappeared by the time they arrived in that region of space.Just before the outbreak of the Third War for Armageddon, Ghazghkull allied with the Bad Moons Ork Warlord Nazdreg Ug Urdgrub to launch an assault on the Imperial world of Piscina IV. The Orks used a previously unknown form of teleportation technology that let them maneuver their troops directly onto the planet from a Space Hulk located a large distance away from the planet. The Imperial garrison was taken completely by surprise and only the presence of Space Marines from the Dark Angels Chapter saved Piscina from being overrun by the greenskins.However, this defeat proved to be of little consequence for Ghazghkull as the completion and testing of his new "tellyporta" by the Ork genius later dubbed "Orkimedes" by the Imperium meant that he was finally ready to unleash his full force against the Imperium. After more than fifty years, Ghazghkull and his Orks intended to have their revenge.
