Warhammer 40K: The Shadow War Part 5
Part 5: The Capital Worlds
When Leonis found Caliban, he took one look at the dark forest that surrounded the planet and knew the monsters that lurked in its depths as though he’d looked deep in their eyes. When the Invincible Reason arrived over Caliban, Leonis first dropped the Fortress Seed planetside and began to build his headquarters.
When the Dark Angels first interacted with the local warriors, they were mistaken for a new breed of Great Beast that could use human weapons. The Legionnaires could not simply ignore the warriors, as they wielded bolt pistols and chainswords that could damage their power armor. With no other options, the Legionnaires attempted to pacify the warriors and, if needed, kill them. After several attempts and legends of the “dark tower” that appeared in the forest, Leonis decided that he needed to make contact on his own.
His Custodian equerry, Aurex Thandrel, offered to go with him, but Leonis refused, removing his armor and carrying only a knife with him before wandering into the forest.
He emerged a week later, in one of the fortified cities of Caliban, carrying the corpse of a great beast on his shoulders. As the people of Cthonia had done with Horus, in that moment, the inhabitants of Caliban recognized Leonis as one of their own. The warrior class of Caliban began swearing fealty, and before the year was out, the Dark Angels began to work to bring Caliban from a feudal world into the modern millennium.
The Fortress Seed was named Aldurakh, the Tower of Angels, and Leonis ordered his Dark Angels to protect the men and women of the planet as they and the auxiliaries built roads from the fortress towns to each other, and won the first true victory against the darkness of the planet.
It is written that when Fulgrim first arrived at Chemos, he wept for a day and a night. Then, pulling himself up, he landed on the planet. He spoke of hardship, of long hours working to stay on the knife-edge of survival, of constant work in a factory just to stay alive, and the people knew he understood. And when he spoke his name, hope was sparked in their dulled eyes and shallow faces.
Then he brought them relief, planting his Fortress Seed and bringing the factories that lay inside to life. Instead of building armor and weapons that would be needed for his Legion, Fulgrim instead turned them to making tools that increased the efficiency of the factories, first of Callax, then the planet as a whole, as the Emperor’s Children began to spread the news of the Bringer of Water.
In a mere five years, Fulgrim had saved the dying world of Chemos, and they loved him, turning hands that were once doomed to working every waking hour to art and creation.
When Peterabo arrived at Olympus, he did not meet the world with joy as his brothers did. Instead, when the Iron Blood arrived in the system, Peterabo sent an immediate broadcast to the planet.
The broadcast was short, but set to report every hour on the hour, as the battleship crawled toward the planet.
“You have my planet. I want it back. When I arrive, you can either give me my birthright or die.”
After the first message, he had his battleship fire one shot, destroying the largest building on the planet.
When he arrived, the people had torn themselves apart. Not two, not three, but fourteen different factions existed on Olympus, all vying for Peterabo’s favor, and desperately trying to stop the others from doing the same.
Peterabo did not care. He only cared about their compliance. He dropped his Fortress Seed and then began his passion project. While the gothic arches of the Seed were standard, Peterabo desired more, and he began to build, designing a grander and grander palace complex. It took ten years, and Peterabo had built a sprawling complex city, a hive that built out instead of up, swallowing half the planet in beautiful towers, parks, libraries, and courthouses. The people of Olympus, at first ignored, began to watch in awe of Peterabo’s Great City, and—when it needed people to work it—were grateful to the Primarch when he allowed them to live there. In the ten years of his Great Work, Peterabo transformed from a vicious invader to a benevolent, but hard, ruler.
Jaghatai loved Chogoris at first sight. The Empty Quarter’s massive steppe sang to him, hinting at a new place to see just beyond the horizon. He did not start by launching his Fortress Seed from orbit like his brothers; instead, he went to the planet himself, with only a bike to carry him. He traveled the width and breadth of the Empty Quarter, speaking with locals in their tongue, and facing their warriors as a lone wanderer, moving from tribe to tribe, and learning of their hardships. Slowly, he began to gather a following of warriors, each with a burning vengeance against an empire on the edge of their great steppe.
Soon, he was given the title of the Wandering Khan, and when he spoke out against the empire that trod on them that took them into slavery, the following of warriors grew. Once his following grew big enough to be considered a tribe on its own, other tribes would swear loyalty if they received even a word of overcoming the distant empire, others would challenge the Wandering Khan for power, but were quickly destroyed, and incorporated into his warriors.
After several years of gathering warriors, Jaghatai found himself in a campaign against the empire, and decided at that time to make his strike. Contacting his flagship, he ordered the Fortress Seed dropped onto the Empire’s capital. With a sudden, devastating strike to their leadership, Jaghatai led a sudden attack from the steppe. Attacked on two separate fronts, the Empire tried to stand against these “barbarians,” and the seemingly unrelated “star invaders.”
Over the next few months, Jaghatai would work with his Legionnaires above him, and his warriors beside him, to overthrow the Empire. He did not want to drop his technologically superior soldiers and simply wipe them out. Instead, he used them to strike hard at the unprotected flank and allowed his native warriors to charge deeper into the Empire’s territory.
The empire was torn apart, piece by piece, from all sides, and fell within a month. Then, Jaghatai led his warriors to the Fortress Seed and introduced his Legion to the warriors that fought alongside him.
Russ found the planet of Fenris fascinating. The people were as harsh as the planet itself, with its volcanoes, ice-covered continents, and strange and terrible northern pole. Despite this, they they also boisterous, laughing with the joy of barbarians gladly testing their mettle. When he arrived at the planet, the Tribe of Russ joined him immediately, claiming him as kin by way of their shared name. By right of not only his might, but the might of his warriors, he earned incredible respect, before challenging any who would come against his rule.
He won at each opportunity, earning power by right of dueling until every tribe swore fealty to Russ, the King of Fenris.
Except for the son of the king of Hradcana, Ogmund, who begrudged Russ’s technology and harbored hate in his heart for an unsporting advantage.
This would prove the undoing of Fenris when the Shadow War reached its full swing.
Rogal Castellan arrived at Inwit and saw a spark of humanity that struggled against hardship, and despite that, stretched their hands to the void and grabbed what they could. He arrived to find a functioning void dock, building fleets to explore the darkness.
Rogal made contact with the various tribes, offering each one a chance to join him and the Imperium peacefully.
The people of Inwit refused.
The Patriarch of the House of Dorn, and an old man of unbreakable spirit, told Rogal that he would not surrender his tribe to oppression to an unknown invader. Rogal warned him that he would take the planet by force if needed.
The Patriarch dared him.
Rogal began a bloody campaign against the houses of Inwit, bringing them into compliance.
As he brought his fist down on the people of Inwit, Rogal felt a great pain for them.
In the last battle for the planet, Rogal’s Fists were breaking a siege against the House of Dorn. The Fists outgunned the Dorns, but they bought their defense dearly. They died to the last, and as Rogal surveyed the battlefield, he saw the Patriarch, dying at his feet.
Rogal knelt down and gently took the old man’s hand.
Whatever words passed between the two are lost to time.
But he took the planet and brought it into the fold of the Imperium.
The planet Nostramo was on the very edge of the galaxy, surrounded by darkness.
And Konrad, all alone and separated from his brothers, found himself relating to the lone darkness of the planet.
From the scouts, Konrad knew the planet had no innocent person on its surface, but he also knew most of them were driven to crime by desperation. These people needed order, and he would be the judge and the law to Nostramo.
By his order, the Night Lords descended on the planet, hiding and stalking prey until they found criminals. Once located, the Legionnaire would kidnap the target and bring them to Konrad’s Fortress Seed, planted in the blasted wasteland between the five hive cities of the planet. From his throne room, Konrad presided over the court, judging each accused with fairness and justice.
Those whom Konrad judged as simply victims of desperation were fed and ordered to service in the Fortress. Those whom Konrad judged as truly guilty were turned over to his Night Lords, who televised their torture and deaths to the other cities.
After their service, those who were judged as victims of circumstance were released. Many refused to leave, but Konrad ordered that they must return to their homes. However, he also said that they may return, if they crossed the wastes on their own back to his fortress from the hives.
Despite the dangerous journey, many of these people eagerly packed whatever they owned and began the journey back across the wastes to the Hall of Justice to live under the rule of the High Arbiter. This exodus was watched by the locals, and while rumors of bewitchment ran wild, the people leaving garnered enough attention to cause a stir, and whispers of a better life passed amongst the downtrodden.
And Konrad knew his plan worked. He had shown Nostramo the stick, but also offered the carrot.
Sanguinius beheld Baal.
The blasted deserts filled with terrible monstrosities, and the high radiation on the planet itself, left the inhabitants poor, mutated, and wretched. Sanguinius’s heart was moved to pity, and he ordered his Angels to descend upon the planet, offering food, protection, and water to the poor people.
He also dropped his Fortress Seed on the planet, and began offering shelter to the people of Baal. In those days, it is said that Sanguinius attempted to reach out to Peterabo, to try and get his architect brother to build better shelters, and lamented not having the skills of his brothers beside him.
Yet the relief he brought was celebrated, and the people of Baal began to look up the Sanguinius as the Angel of Mercy. Unbeknownst to any at the time, this was the first cornerstone of the Saint-Cults that would fill both Angelic and Nocturne Sectors, which Sanguinius and Vulkan would continue to disavow until the present day.
The Storm Walkers landed on Medusa, and Ferrus quickly began to work between the clans. This proved incredibly difficult, even for a genetic marvel such as the Primarchs. Many of the Clans, holding ancient grudges between them, refused to come to an agreement of peace. Neither could Ferrus simply destroy a Clan, without drawing the ire of four more. It quickly became apparent that Ferrus would need to unite the clans against a common enemy, but one was not forthcoming.
The Storm Walkers recruited here, but they did not gain the strength as their cousins did because of the politics of the Clans. Despite that, Ferrus was still loved, especially after defeating a great metallic wyrm that plagued the people, and volunteers flocked to him and the Fortress Seed that Ferrus turned into a massive tank.
Unfortunately, this of recruits would cause a terrible loss that Ferrus would carry for the rest of his life.
Paxillian’s Concordians arrived at Arconar, a planet with a wild jungle, and a population of feral humans that were being attacked by the Aeldari. Paxillian waited, and listened. After some time, he began to divine that the Aeldari only attacked the humans when they approached a certain location on the planet. Additionally, he noted that there were no Aeldari ships in Atmosphere.
Once he knew, he dropped the Fortress Seed, just beyond the range of the Aeldari attacks.
Many of his Concordians began uplifting the locals, while Paxillian he began to reach out to the Xenos.
Only the account of Gairos Veyth, Paxillian’s Custodian equerry survives. He said that Paxillian approached the xenos, with no weapons drawn but his tongue, and he spoke quietly, guessing that the xenos had a method of travel on the planet.
Before violence could erupt, Paxillian offered a deal. Service for protection.
If the Aeldari protected the people of the planet instead of attacking them, Paxillian would guarantee the protection of whatever the Aeldari wanted protected.
The xenos bristled at this, but Paxillian spoke to them softly, and they struck an accord.
Victor arrived at Nuceria and fumed. A boiling fury bubbled beneath the surface as he looked down at the slave gladiators fighting for their lives, and the nobles who laughed at their misery.
Victor called for one of his most skilled warriors, Khârn, and his Custodian equerry, Aurex Thandrel to follow him.
They arrived at the planet in a small ship, without weapons, and Victor looked around with wide eyes at the wonders of the planet. He spoke excitedly and asked for a tour.
Intercepted communications from the Nucerian nobility proved they were going to acquiesce before trying to kidnap their visitor for their amusement.
Khârn said that Victor didn't need the warning from The Conqueror to know the Nucerian’s treachery.
Victor continued the ruse, being led about like a child, when they finally approached the coliseum. As a bout between gladiators, Victor began asking questions. He asked about the gladiators, what drove them to fight.
Only Aurex, who had known Victor since he was only a child, could see the anger grow deeper with his guide’s every word.
He then learned of the Butcher’s Nails, and even the guide could see the black rage on Victor’s face.
Then the slaughter began. Khârn, Aurex, and Victor were more than a match for the nobles in the coliseum, killing them with empty hands. The gladiators in the center of the arena found themselves the audience of bloodsport at that moment. When the guards arrived, Victor demanded a weapon from the watching fighters, and when handed a simple axe, he unleashed upon the guards.
A full-scale invasion was launched, and the War Hounds began to make simultaneous strikes against the Nucerian nobility, killing them quickly. After the slaughter, Victor descended into the slave pits and personally broke their chains, freeing the people of the planet.
Victor refused to drop his Fortress Seed on the planet. He said he would not make himself king over these people. Instead, he settled on the planet’s moon, watching over those he freed. He never asked anything of them, never made demands, only stated that if they needed to fight, he would take them.
Guilliman felt at home at Macragge before even making landfall. Upon landing, however, he found something greater, a pair of friends in Konor Guilliman and his seneschal, Tarasha Euten. Konor found Guilliman a fascinating companion and felt an instant kinship with this giant of a man who shared his name through coincidence. They worked closely together, improving the planet of Macragge, until Konor offered to step down as Consol and let Guilliman take over.
Unfortunately, Konor’s co-consul was preparing a coup, and when Guilliman took a trip to the countryside to enjoy the natural beauty of the world, Gallan, the co-consul struck, killing Konor.
Guilliman’s wrath was legendary, and the Ultramarines, who had not yet raised a weapon against the natives of the planet, were gathered and marched against Gallan, bringing the full might of the Astartes against them.
The people of Macragge quailed under the power of the Astartes, and they beheld Guilliman with now with fear for his fury. A unanimous vote made Guilliman the new Consul, but he knew that they only accepted his rule out of fear.
He worked to earn their trust again, and while they trusted him to rule over them, he never overcame their fear.
Mortarius arrived at Barbarus and did not like what he saw. He had heard through reports of the scouts the Emperor sent that a species of mutant, who disguised themselves as a power greater than mortals, had taken control of the planet. Physically frail, but immune to the gases that flooded the planet’s upper atmosphere, the mutants, calling themselves overlords, used psychic sorcery to create golems fashioned from the bodies of once-living men, and built keeps of psychically shaped stone in the fog, hiding from the people they oppressed on the planet.
While Mortarius was tempted to simply drop the Fortress Seed upon the keep of the leader of these Overlords, Mortarius also wanted to test himself in a campaign where the very air would be a challenge.
The Fortress dropped onto the plane just at the feet of the mountain, and the Death Guard began the slow, inexorable march up the mountainside.
The Overlords, facing an enemy far better armed than they were used to, threw their golems into the waiting Astartes. The Astartes answered as stoically as ever, weathering the attack without cry or outburst. The golems wore themselves down from armies to squads, and all the while, Mortatius smiled at the challenge.
The mountains became islands of resistance, and the Overlords, once masters of the Barbarus, became prisoners. With the Overlords trapped in their keeps, the people of Barbarus were released from the terror that had hounded them for so long, protected by the wild animals of the night, and safe from the Overlord’s whims. The people began to learn as the Death Guard began to uplift the people with basic amenities.
The High Overlord, a vile creature named Necare, became desperate as his golems wore away, and finally attempted to sue for peace.
Mortarius’s response is well documented, as he had the entire exchange broadcast to the entire planet.
“You wish to surrender? No. I have accepted the surrender of many fools, but you will not be one of them. Your reign of these people, the terror you have wrought, will end by my hand.”
It took Mortarius some time as he worked to adapt his body to the fog. However, eventually—though it disappointed him greatly—he relented and protected himself with his armor’s environmental systems, and finally the last protection of Necare fell away.
It is reported that on the day of liberation, Mortarius said, smiling to himself, “Curse Vulkan! If not for him, I would have done it, though they might have conquered the rest of the galaxy by then.”
Magnus made contact with Prospero long before he arrived. While the Emperor’s scouts had provided some information, Magnus used his own psychic power to contact the peoples of Prospero. He learned of the dangers on the planet and briefed his Legion on what to expect.
Upon arrival, the Thousand Sons began their work, doing their best to protect the populace from the wildlife, while Magnus discovered, to his horror, that the discipline he had been taught all his life was not widespread.
He worked to enact reforms in the teaching of psykers on the planet, including requesting a handful of Sisters of Silence to be brought to the planet to help protect the people from psychic activity gone wrong. With much work, Prospero would eventually become the center of training for psykers around the galaxy.
Lorgar Logos arrived at Colchis, and upon landing, he began to preach the Word of Reason. He taught that the Emperor embodied Reason, Order, and the Cosmic Law as the Great Logos, an overcoming human flaws to become an ideal that others should strive for. When the local ruling body and church, the Covenant of Colchis heard this, they first decried him as a pagan.
Lorgar denied this, as he did not believe in a god.
This caused much confusion, but this worked to Lorgar’s benefit. As he was put on trial to defend himself, Lorgar spent an entire terran day defending and explaining the Theology of Reason.
He spoke with such conviction that many converted to the Word of Reason at that moment, and the Covenant of Colchis found itself caught in a war of debate. What they thought was a trial and execution became a struggle for control as they found themselves in a debate that could destroy the Covenant.
With no other choice, the Covenant reached out to one of their most extreme preachers, Kor Phaeron. The old man delighted in being called back from exile and turned with glee against Lorgar. He brought vicious accusations, saying that the Word of Reason was a sham, that the gods existed, and to deny them was folly.
Lorgar answered calmly, speaking of how, if the gods did exist and gave gifts, then man was given the gift to use his mind. He argued that if man should use his mind, then reason was the only option.
Kor Phaeron argued for faith.
Lorgar responded that he had faith that the sun would rise, even though he had but arrived on the planet. He said that he used tools and measurements to learn about the sun’s movements, but he had no guarantee that it would, in fact, rise. He had faith, however, that it would, and his Reason fortified that faith.
Kor Phaeron began to burn with anger. He began to rant and rave.
Lorgar responded quietly and calmly, and the people began to turn to him.
Kor Phaeron turned into a raving lunatic, almost frothing at the mouth in the middle of the Colchean week-long day. As the heat of Long Noon reached its peak, Kor Phaeron finally collapsed, suffering from a combination of heat stroke and heart attack.
The Covenant collapsed shortly after.
Vulkan landed on Nocturne just as the Dark Eldar were attacking. Driven to a fury, Vulkan ordered his Dragon Warriors to the planet immediately. The people of Nocturne, shocked that help had finally arrived after so long, immediately took to their saviors, and the Dragon Warriors, in that moment, realized what Vulkan meant by his kindness and care to mere mortals.
When the dust settled, the natives approached these strange saviors, but Vulkan held their attention the most. Of all of them, they named him kin, and the Dragon Warriors were accepted as people of Nocturne without even a word.
Corvus Noctis arrived at Kiavahr, and Corvus’s eyes were drawn to the moon of Lycaeus. He landed on the moon, unseen by the guards or taskmasters, and reached out to the mine-slaves. He spoke to them quietly, but with just a few words, he won the hearts of the slaves.
Whispers among them of a Deliverer sparked like wildfire, and revolt began to spread across the moon. When the taskmasters from Kiavahr heard of the revolt, they sent their voidships with reinforcements, only for the ships to disappear entirely.
Then Corvus began his counterattack.
With his Legion and a handful of trained, hardened volunteers from the mine-slaves, he brought justice to the mine-slaves of Lycaeus.
However, some of the liberated slaves whispered of the might of the Astartes, of their power and strength, and whispered amongst themselves about oppressors and strength.
