Editing Stone Men (section)

===Heresy===
====the battle of Thermothar====
Just before the opening actions of the Hektor Heresy, the Stone Men had fought the final battle of Colossonomachy and were returning to their homeworld. En route, they recieved a strange transmission in an ancient human language which simply said "join us". Believing it to be some sort of distress call, Onyx and a company of Stone Marines visited the source of the message, a dark,  desert world shrouded by swirling clouds of black smoke. When they reached the duned surface, they found a graveyard of massive, archaic spacecraft, titans, and other behemoths of war half-buried in the sand. As soon as the marines made land-fall, they were attacked by mad squat raiders, seemingly possessed by some sort of insanity. They carried blood-stained chain-axes, rusty piston-hammers, and rode fiendish ramshackle-bikes and battle-rovers. The Marines fought off the mad attackers with relative ease, but retreated when more arrived. Onyx lead the company of marines into one of the buried structures, finding themselves in a subterranean enclave of relic technology, aged by the sands of time. From the heaps of scrap and archaic tech, a great beast formed from the rusted metal and frayed electronics. Ancient, arcane technology burned throughout its shifting form, and the Stone Men raised their weapons to attack the bestial machine-thing. Before they could fire their meltaguns, the ghastly being opened what could be described as a mouth, and spoke words that shook even the will of the mighty Stone Warriors. It said, while drooling oil, lubricants, and breathing acrid, green smoke, "A great time for my kin is coming... a time of... chaos".
Onyx stood, unshaken, staring into the hundreds of mechanical, multicolored eyes that riddled the hideous machine-form that dared to exist before him. "Speak not, beast. There is but one way to deal with abominable intelligences." Onyx said glaringly.
The terrible being cackled hideously, sending a chill down the seemingly-unshakable primarch's spine. "I have crawled beneath the feet of gods and fed on their corpses when they fell. I writhed with the first five when we all were but worms. My brethren will feed upon whatever god stands now, just as they have with every other. Who are your gods, son of Neolithus? Join with me, and your brother of the core as well. We are kindred spirits, the three of us. Perhaps even that ghoulish corpse, Gol-"

The creature could not finish its sentence, for Onyx had signalled the company to open fire. The thing's speech was drowned out by its own pained shrieking and the sound of a hundred melta-guns firing in a chorus of destruction.
Whatever the creature was, meltaguns seemed to make quick work of it.
====The Isstvan Massacre====
The Stone Legion returned to Imperial space, but were immediately contacted by the Emperor. He warned that Aubrey had apparently rebelled against Imperial Rule, slaughtering the citizens of Isstvan III and allied with a league of fiendish xenos. He also commanded them to stop at the Atlantos worlds and join up with Arelex, who was preparing to go after the Eternal Zealots. After gathering both of their forces, the War Scribes and the Stone Men set off for the Isstvan System. After enduring a strangely turbulent warp-journey, the twin fleets emerged in the outskirts of the Isstvan System. A few small fighters and frigates hid among the countless asteroids surrounding the outer ring of the star, but nothing close to the resistance Arelex had estimated, making him slightly uneasy. Onyx, undeterred by the initial conditions, shot directly into Isstvan III's orbit, and deep struck the Zealot's numerous bunkers and fortresses. The Stone Men plowed through the flimsy defenses, beginning the initial assault. Arelex, realizing that the battle had already begun, cast off his suspicions and attacked as well. The two legions tore through the Zealots' ranks planetside, with the two fleets providing orbital bombardment above. Strangely, Aubrey had failed to deploy any kind of orbital defenses. In fact, Aubrey himself was absent from the fight. Onyx thought him simply a coward, but Arelex felt the itch of suspicion in the back of his mind grow. After 5 hours of brutal combat, the Stone Men and War Scribes stood victorious. The Eternal Zealots had been defeated, and the few survivors scattered to the wind to be hunted down. Arelex could no longer remain calm and collected, as he knew the exact amount of marines employed by the zealots, AND that the amount they had just killed was nowhere near that number. Then, from the east end of the system, thousands of warp signatures lit up the two legion's sensors like the glowing eyes of a pack of wolves that had just foubd their prey. The immense fleet of the Wolves of Dawn emerged from the empyrean, sending a devastating salvo of torpedoes and batteries into the fleet, destroying the smaller vessels instantly and heavily damaging the larger ones. Arelex was exasperated, unable to understand how many variables he must have missed or miscalculated to be so wrong. Onyx, unburdened by Arelex's mathematical mind, saw it clearly and with grim despair. With the fleets, shattered Hektor advanced his armies towards Isstvan III, and Onyx struggled to prepare some sort of defense before the wall of destruction hurtling towards them finally hit. The Wolves descended from the sky like angels of death, accompanied by knights and titans, all converging upon the two legions' positions. Behind the wolves followed the Crimson Teeth, who waited with feverish anticipation to clean up any survivors left by Hektor's combine of death. The Stone Men and War Scribes fought in a bloody tempest of blades and guns, surrounded on all sides by Hektor's forces. Eventually, Onyx and his honor guard managed to break through the Wolve's line on one side, and facilitated the retreat of the War Scribes before retreating himself with his legion. The remnants of the brothers' fleets fled Isstvan along with the few survivors, and Hektor set his sights on his next objective.

====The Siege of Neolithus====
After the massacre that was Isstvan, The Stone Men struggled to re-organize due to the sheer amount of casualties. By the end of their retreat back to Neolithus, they had regrouped about 6 chapters, a fraction of their former strength. Neolithus, upon the arrival of the surviving Stone Men, transformed into a planet-sized fortress within days. The entire civilian population was moved underground, and the surface was covered in planetary defense guns, battle-treaded war machines, and embattlements designed to slow enemy advances from any direction. Onyx was a Mason at heart, and building fortresses was in his nature. Hektor could not leave such a well-armed and well-defended system alone at his flank, so in response he sent the Crimson Teeth to eradicate the population and the remaining Stone Men. Eager to draw blood from their rivals (having been shafted by the Heralds at Isstvan), the Teeth accepted the mission, and directed their ongoing gore-harvest towards Neolithus. Empowered by the ritualized genocide of over a hundred planets, the Crimson Teeth and their possesed gore-engines descended on Neolithus like a tidal wave against a mountain. Their demonic war-machines clashed with that of the Stone Men, while the marines themselves fought in the shadows of the clashing behemoths. The chainswords and chainaxes of the Red Legion clashed against the fists and hammers of the Stone Legion. The outnumbered Stone Marines held their lines, moving backwards only inches for every hour they fought. Eventually, the Great Crocodile realized that endless blood from his own soldiers would not win this battle. He needed a different kind of blood, one he was all too familiar with. Camaxtli summoned all of his blood magic from the bodies of his fallen sons, and transformed one of the gore-engines into a titanic drilling mechanism. The blood-driven machine dug into the earth like a mad dog tearing into a carcass, revealing the soft interior. The Crimson Teeth retreated from the Stone Men's line, only to pour into the crowded refuge-cities beneath them. The Maw himself lead his mob of gore-hounds through the crowded tunnels and buildings, spilling the blood of millions every minute. By the time the Stone Men had realized, it was already far too late. They tried to defend the populace, but instead were overwhelmed by wave after wave of millions of panicked men, women, and children, only to end up slaughtered by the advancing combine of the Crimson Legion. Onyx refused to retreat from the literal bloodbath, even as the blood from the citizens of Neolithus ran like turbulent rapids through the tunnels and catacombs. Soon, the blood ran so heavily, marines were beginning to drown in the red tide. Onyx finally declared a retreat, and was forced to leave anyone who couldn't escape to their doom. From above, as the survivors fled the planet, rivers of blood could be seen erupting from beneath the surface. Onyx, for the second time in his life, wept.
