On the fortress-world of Brigantia III, General Milus Montague of the 47th Heavy Columnus had two million Imperial Guardsmen amassing for a push on the Zodiox Rift — including honoured regiments of the Phaxatine-of-Foot and Droonian Longshanks. The sparse systems of the Rift had become a petri dish of alien infestations: the Hrud, the Noulia and the Chromes. The xenos filth lived to spread their contagion another day, however. As something colossal attempted to break through into the reality of the Brigantia System, the fortress-world trembled and then succumbed to unseen and unimaginable gravitic pressures. Despite its bastions, armour formations and millions of Guardsmen, Brigantia III had no defence against the intrusion of another world.
The planet exploded. As gargantuan chunks of fortress-world rocketed away, demolishing the flotillas of super-heavy troop transports and Navy escorts waiting to receive General Montague’s Zodiox crusade force in orbit, another planet had taken its place. A small, black moon: one of many appearing throughout the sectors of the Inner Rim like bad omens.
Amongst the calamitous roaring of the Beast and the gravitic disasters afflicting worlds, these unnatural satellites materialised across the rimward sectors. The heralds of catastrophe, they ripped through reality to take their place among the ornamental orbs of busy Imperial systems. Some were black like coal, eating up the light reflected off nearby stars and planets. The surfaces of others were a collage of wreckage and plating, rusted into an armoured shell. The rock monstrosity above Arx II Antareon bore a colossal clan glyph painted across its ugly face, while the attack moon rising over desert world of Sanveen was a mechanical horror — a patchwork metal skull grinning down on the doomed Imperial citizenry with alien drollery.
Praxedes Prime was one of the first recorded worlds to experience the attack moons’ gargantuan weapons. Gravity beams struck the shrine world’s surface, chewing though the sovereign city states and tearing temples, basilicae and cathedrals violently skywards. Light years away, Port Oberon — a fleet base situated near a busy subsector ether-nexus — was pulverised. Colossal rocks, meteorites and planetary chunks, vomited forth from gaping launch craters in the pock-marked surface of a materialising attack moon, smashed through stationed sentry cruisers and fleeing merchant shipping.
The worst was to come, however. As well as rocketing projectiles and graviton beams, the attack moons unleashed plagues of ramshackle gunships, salvage hulks and rammers that enveloped escaping vessels in a web of grapnels and gunfire. Survivors on victim worlds climbed out from the wreckage of demolished cities, their eyes fixed on the slaughter above and the attack moons glowering down on them. They watched until their skies grew black — black with the swarms of descending rocks, landers and greenskin capsules. Oblivion beckoned.
This was not the first time the Inner Rim had suffered greenskin attacks. In recent memory, the Archfiend of Urswine had led its invasion into Subsector Borodino. The orks poured into the Grange Worlds like a green tide. Their decimation of the agri-world crops and tenders brought the nearby hive-world of Quora Coronis to the brink of starvation. It took the best part of a decade for the Coronida 3rd through 9th Indentured and the Royal Borodino ‘Blues’ to drive the Archfiend and its splintering horde back to its degenerate empire.
The Beast was not the Archfiend of Urswine, however. The Archfiend’s invasion force, while a savage sea of green into which Imperial worlds went to die, were mere runts compared to the Beast’s hulking monsters. Amongst the Beast’s countless number, the Urswine orks would have been trampled under foot. Even the greatest of the Archfiend’s brutes — perhaps even the Archfiend itself — would have been lost in the shadow of the Beast’s invader savages. The puniest of the Beast’s monsters were small mountains of muscle, standing snaggle-jaw and shoulder over other orks. Striding through the mobs and madness were greater beasts still: towers of tusk, green flesh and ferocity. Like gargants or giant effigies of greenskin gods brought to life, these hulks carried colossal weapons that demolished buildings at a single strike and monstrous guns that mangled infantry and tank formations with equal, bloody ease.
