The Purging of the Invocastus Sector
The Pale Stars
As the Age of Darkness ground ever onwards, the fires of war would spread throughout the entire galaxy, consuming everything in their path. Armies and worlds were reduced to nothing more than ash, in many cases leaving no one alive to bear witness to the sacrifices made or the atrocities committed. During this time, each Legion employed unique formations to prosecute their own style of war, whether by choice or through necessity, making use of unconventional, often abhorrent, tactics and weapons. Many of these formations would be lost during the dark years following the Horus Heresy, their traditions wiped out and the last stockpiles of their weapons exhausted. Some, however, have been preserved in these records, that future generations may learn of the terrors unleashed upon the galaxy by the Emperor’s turncoat sons and the valiant heroes who stood against them.

In late 012.M31, augur beacons that had remained dormant in the cold abyss of the void space bordering the Pale Stars began to awaken. They were stirred from their slumber in a region rarely travelled and so far little troubled by the war by the passing of increasing numbers of ships bearing the code-idents of the IIIrd Legion and relayed the alarm to Salamanders forces garrisoned on Nocturne. Capitol ships were followed by a stretched convoy of numerous other craft all fleeing the ruins of their home world, Chemos, to seek refuge within that desolate and empty region. In response, the XVIIIth Legion mobilised what forces they could from the few warriors and Inductii that remained on Nocturne, intent on intercepting the Emperor’s Children before they were able to reorganise, rearm and establish a new domain from which they could strike with impunity at Imperial worlds across the southern sectors. One such Salamanders fleet, led by Praetor-commander Brant Hesioth, tracked the IIIrd Legion frigate Pernissus to the Invocastus system and closed in with haste, keen to deliver a swift death to the Traitors. The turbulent and irradiated rad-wake that railed behind the Traitor ship led Hesioth’s fleet into the high-orbit of Invocastus IV, a planet that once thrived on its mining prospects but a place where industrious activity had started to dwindle even prior to the outbreak of the Horus Heresy. Hesioth found the scuttled hulk of the Pernissus adrift amongst a flotilla of similarly abandoned frigates and cutters, all empty of their emergency escape pods and devoid of their crew, abandoned in a decaying orbit over the planet’s capital, the Amethryne City. Determined to eliminate the Emperor’s Children forces before they could consolidate into a substantial threat, the praetor-commander ordered his forces to make planetfall. Unbeknownst to the Loyalists, the IIIrd Legion had gone before them and their insidious whisperings had swayed the disenfranchised people of this isolated world, turning them against the Imperium to such a degree that the entire population would rise in rebellion against the forces of the Emperor. Anti-Imperial graffitih ad been daubed on the walls and the synth-velum pages of propaganda pamphlets littered the streets amongst the detritus of lives long forgotten by the ceaseless expansion of the Imperium. The men and women of the hab-city spilled from every doorway and filed from alleyways bearing all manner of weapons as, like the judgement of heaven itself, the heavy landers of the Salamanders Legion descended. Assault ramps hinged open and the first waves of Space Marines deployed into staging areas around the outskirts of the city. The brooding threat of the orderly and disciplined ranks of Legionary warriors, whose boltguns were levelled on the sea of bodies that rushed to meet them, enforced a no-man’s land between the two lines. Hesioth addressed the Amethryne people, his voice amplified through the vox-hailers of every landing craft. He appealed for the peaceful surrender by the Amethryne people, for them to lay down their arms and to reveal the whereabouts of the IIIrd Legion enclaves upon the planet. Privately, the praetor-commander harboured hopes that any mass uprising could be quelled without conflict, since his command had barely the numbers to commit to aminoris-level pacification action.
Undeterred by the show of Imperial force, the Amethryne militia enacted their defiance by unleashing an undisciplined barrage of lasbolts and frag-shot that were mostly deflected harmlessly by the ceramite plates of the Salamanders’ power armour. Hesioth’s force opened fire, sending mass reactive bolts into the oncoming crowd, blasting unarmoured bodies apart in a wet mist of atomised gore, but the intensity of the counter-attack was undiminished. The Salamanders stood resolute, the blast of their bolter fire a constant roar as each squad alternated between firing and reloading in drilled order. The missile launchers of scorpius artillery tanks and arquitor bombards rained explosive fragmentation missiles into the crowds in an effort to thin their numbers. Within minutes, the squadrons of fire raptors that had accompanied the landing assault reported critically depleted ammunition levels, having opened fire with their heavy bolter batteries and rotary cannon at the first instances of hostility and had sustained continuous fire on the riotous masses during that time. After several hours, sanctifier squads leading the Salamanders’ push into the city’s interior sectors reported extreme ammunition depletion, having used their rapid-firing weaponry in disciplined bursts to sweep through building interiors and clear streets as they advanced, tightening an inescapable cordon around their IIIrd Legion quarry. Hesioth’s delegate logisticians were forced to coordinate the orbital drop of supplemental munitions and distribute them to the troops that had pushed onwards into the city. Tirelessly, the militia fought on, climbing the heaps of their own dead to hurl themselves at the Salamanders’ guns and still the traitorous IIIrd Legion were yet to openly join the battle.

The Invocastus System

Due to its location in the Pale Stars, the Invocastus system lies far from the main warp conduits used to traverse the galaxy and as such was not used as a way-station or supply hub by the bulk of travellers in the manner of many other notable systems. In the time of the Great Crusade, however, industrious activity and planetary mining operations ensured the system’s tithes were sufficient to afford inclusion within the cartographies of Imperial space. The remote location combined with the protection provided by the Imperium ensured that the system enjoyed long periods of relative peace and on some of the inhabited planets, including Invocastus IV, the population thrived. Long-established cities expanded into vast metropolitan complexes where artistic creativity and education flourished in an age of plenty. Theatres and auditoriums hosted plays and philosophical seminars, museums and galleries sat at the hearts of communities where the people lived as equals in a harmonious society. This period of heightened civilisation was, however, finite and began to dwindle out as the Great Crusade stretched the boundaries of Imperial space. The value of the Invocastus system’s industrious output was effectively reduced as new frontiers were explored and other locations along the primary warp routes were uncovered. The academic and creative endeavours of the population were soon exceeded by mundane, ceaseless toil and political unrest erupted as the majority of the population worked to pay taxation levies implemented to sustain the heady lifestyles of the ruling castes. Over the course of generations, civil unrest grew, burgeoning and prosperous settlements descended into impoverished mass-dwellings and their inhabitants resorted to crime and corruption to survive. The wealth built over centuries of comfort and productivity was squandered in a fraction of the time it had taken to accumulate and the population rebelled to overthrow their governors. The once busy star ports that ringed the primary planets of the system fell into disuse and dilapidation, becoming harbours for criminal barons and self-appointed overlords that exerted control of the meagre remnants of a once bountiful age through fear and violence. Gangs territories were divided by hab-block sector codes, the most powerful groups holding influence upon entire districts, leveraging control over the limited availability of base resources such as water and nutri-supps and profiting from the distribution of more illicit commodities such as lho-sticks and narco-stimms. As time passed, these gangs accumulated arms and assimilated their rivals, often by force, dividing Invocastus into warring macro-clans. The coming of the IIIrd Legion, although diminished in strength by the destruction of their home world, Chemos, still represented the arrival of an overwhelmingly powerful force. However, it was not through the application of force that the Emperor’s Children garnered control of Invocastus though, instead they took advantage of there sentment of the Imperium that the people of Invocastus shared. With the promise of means to take revenge upon the empire that forgot them, Fulgrim and his Legion once again united the people of Invocastus with a shared purpose.
