User:Montonius/Sandbox - The SPEEDWAAAGH!: When the Ork invasion came to Vigilus it was sudden, and its scale caught the Imperial defenders off-guard. At first contained, it would soon bring to light unseen threats that had lingered on the Hive World for many Terran years.By the end of the 41st Millennium, political and social tensions on Vigilus had risen. The Adeptus Mechanicus triggered ever more frequent earthquakes in its constant hunt for blackstone ore, while a power struggle had developed between the Planetary Governor's ruling dynasty and the Adeptus Ministorum. The struggle eventually escalated into outright if covert violence between their chosen agents.It was then that the Great Rift appeared like a wound in the sky, and from its depths hurtled a fleet of ramshackle Ork spacecraft into the Vigilus System.The rift had obfuscated the foresight of the world's Sanctioned Psyker seers, and so there was little warning of the Ork invasion's approach. Its fleet punched though Vigilus's naval cordon with overwhelming force, then crash-lsaned its ships in the great deserts that existed between the hivesprawl "continents."Those that survived, protected from destruction by bubble-like force fields, formed ready-made fortresses, which became the heart of the so-called "Scrap Cities" from which the Orks would attack the hivesprawls. What they lacked in organisation and structural integrity they made up for in sheer mass and firepower.For solar days the Vigilant wastelands echoed to the hammering of metal, the thudding of rivet guns, the guttural commands of Ork Mekaniaks and the throaty roar of smoke-spewing engines. Vehicle by vehicle, then swarm by swarm, a hundred mechanised invasion forces emerged at great pace from the dust-bowls. The SPEEDWAAAGH! had begun, and at their head rode the Speedlord Supreme, Krooldakka.The Orks were stymied, at first, by the Bastion-class force fields that surrounded each hivesprawl. The invaders were forced to content themselves with raiding the convoys and armoured regiments that braved the wastes and deserts, either to escort dignitaries or move materiel from one continent to another.Some Orks took to racing one another around the planet, even skirting the edge of the vast and constant dust storm known as the "Vhulian Swirl."When the Great Rift grew to split the galaxy entire and the Noctis Aeterna dawned, cutting the Imperium Nihilus off from the light of the Astronomican, the baleful emanations of the rift's Warp Storms washed across Vigilus. The eddies of psychic disruption caused a plague of nightmares to intensify in the populace, but worse still, collapsed all of the psy-tech force fields that kept the Orks from attacking Vigilus' cities.If the Orks had been a rational, right-thinking race, it may have taken them solar days to capitalise upon the lack of force fields. But with their Speed Freek outriders constantly daring one another torun through the perilous energies -- or at least get as close as possible -- it was less than a solar hour before word spread that the Imperial defences were down.When the Orks got wise to this they wasted no time, and poured into the outskirts of each city in tremendous numbers. The Adeptus Mechanicus, Astra Militarum and Orders Militant of the Adepta Sororitas that defended the hivesprawls' borders found themselves engaged on all fronts, and within days they were fighting desperately to slow the Orks' momentum.Even the bio-dome hivesprawl of Mortwald, protected by a network of traditional trenches and bunkers as well as force fields, suffered invasion -- as the Ork attack intensified, Mortwald's succulent and heavily curated forests and expensive rejuvenat treatment complexes were ransacked in several districts.
