Beginnings
Sprawling desert and rocky crags cover the vast majority of the planet Khessar. Scattered Oases, the Great Seas, and the winding rivers feeding into them have allowed for humanity's continued existence on this planet throughout the terrible millenia of strife. Though this planet's history has long since faded into legend, derelict ships, structures, and long forsaken cities serve as a reminder of humanity's past glory.
The Primarch who would be christened Orotos would find himself on this planet, landing near the village of Ilharam. He was taken in by a landowner named Mekir Zomas, who saw this Star Child as a blessing from the gods.
Zomas raised Orotos as an heir of sorts. Although he had his household servants act as caretakers, he assisted with his adopted son's education. At the same time, Orotos had shown a brief interest in the work of the serfs/slaves/sharecroppers who worked the estate, even assisting in their work. Given his innate vitality, the young Primarch easily endured and carried through what most would consider backbreaking labor. Although unexpected, Zomas encouraged this tendency, extolling the virtues of hard work and setting Orotos as an example that the workers of the estate should strive to emulate.
Naturally in this environment, both the estate workers and Zomas would play a role in influencing Orotos's worldview. The servant caretakers told him various stories, involving places of legend such as far off paradise of Terra, humanity's birthplace, where water, trees, and wheat were plentiful. As he hung out with other children, they sometimes spoke of hidden treasure, buried in the lost temples and ships of humanity's past. As Orotos learned early on that he was himself a Star Child, he internalized the idea that these treasures were his birthright.
Still, Orotos had grown up in a society where slavery and indentured servitude were simply part of the natural order on Khessar. Even if he may have viewed the slaves and serfs that lived on Zomas's estates as part of the extended household, Zomas did much to ensure that Orotos was distinct from them. The people, Zomas liked to remind his adopted son, had fallen to their status because they had given in to idleness. They, or their ancestors, had not worked hard enough in life, had not striven to maximize the fruits of their labor, they had not been judicious in their expenses… any number of excuses for why they had fallen to their circumstances.
It is not clear how much the young Primarch took in Zomas's words at face value, but perhaps because he grew up understanding he would be Zomas's heir, Orotos seemed to naturally gravitate towards his adoptive father's outlook.
During these formative years, Orotos took a peculiar interest in bookkeeping, glancing over logs for the expenses and sales of the estates. He even accompanied Zomas's personal broker to different towns throughout the region of Fasaram, keeping a meticulous note on the prices of different goods. Exposed to the different town markets, he even saw some vendors selling bionic machinery and other devices scrapped from old ships, though he thought some of their prices were ludicrous.
It was during one of these excursions that Orotos also caught a glimpse of the forces of the Grand Duke, the sovereign over Fasaram. Not only did their uniforms inspire awe, but some rode on motorbikes and cars resplendent with gems, both vehicles the pinnacle of rarity reserved only for the military and the highest nobility. Even though Orotos's father seemed to be well off to the point of owning servants and slaves, there were still those who were higher on the social bracket, and Orotos wanted a polished, shining car for himself as well.
Give the oddly exorbitant prices of scavenged tech, Orotos briefly wondered whether he should go into the scavenging business himself, especially if he might be lucky enough to find a car or something better from the mysterious ships that were said to be beyond the sands.
So life continued for Orotos, as he continued to assist his adoptive father with the estate. He discovered more profitable places to sell the estate's produce, and helped expand the estate buy finding farmers and other folks who were down on their luck and advising his father to buy their lands.
The Rat War
Orotos's peaceful lifestyle would receive a violent interruption. A horde of Rats, who came from beyond the furthest reaches of Fasaram, descended onto the fertile riverbanks, devastating towns and villages wherever they went. Orotos's hometown of Ilharam was among the first places to be attacked. The Primarch together with a band of folks he rallied managed to survive the onslaught, though Zomas was not so lucky. Orotos grieved for his adoptive father, though he did not mourn for long, believing that Zomas would not have wished him to remain idle so he could rebuild the estate.
Before he could do that, something needed to be done about the rat problem. Orotos and his growing band began to march down river and towards Fasaram's capital, hoping to petition the Grand Duke to send an army to deal with the rats. Fighting more rats as they went, they saw more villages that had seemingly been destroyed from the invasion. Eventually, they ran into an impromptu fort established by the Grand Duke's forces, where other refugees had gathered. As this army suffered significant to the rats, Orotos and his band discovered they were willing to accept recruits on the spot. Orotos, seeing the sorry state the army was in at this point, decided to volunteer. Although duty and fellowship with his countryfolk may have played a role in this decision, what motivated him most was the understanding that he would not be able to fully reclaim the land that was his until the rats were gone for good.
It quickly became apparent that despite possessing motorbikes, cars, and even some still functional weaponry from before the Age of Strife, there were far too few of them to effectively fight back against the hordes of rats. With limited equipment and arms, it was forced to defend instead of reclaim the devastated lands. Newer recruits had to stick with far simpler weapons, or otherwise improvised gear. There was also the issue that the Grand Duke's Marshall had recently died fighting the rats, and there was still some disagreement among the command about who should take charge, at least until the Grand Duke made a decision on a replacement.
Orotos took all this in and more, despite not having training for command. He aided the fight against the Rats where he could, focusing efforts on places Orotos knew from experience would have goods useful for the war effort, and leading raids to retrieve vehicles that had been lost in botched offensives. His feats, skills and effort slowly gathered him renown throughout the Grand Duke's forces.
Eventually, the rats were cleared from Fasaram, although Orotos feared they would come back again if they were not eliminated from wherever they came from. Nevertheless, Orotos and the rest of the army, seemingly victorious, went to the capital to receive honors and the like from Grand Duke Ezam. The Primarch and some of his colleagues had received rank promotions, although Orotos felt they didn't quite measure to his contribution to the war.
Ascension
Still, this was hardly the end to his rise in fortunes. There were now great swathes of land within Fasaram that lay unclaimed because their owners and/or heirs were now dead. Orotos, always keen on increasing his fortunes, had taken note of which families owned which estates, even speaking with some of the displaced peoples to determine their claims. He petitioned the Grand Duke about this matter, and received some lands in the process, although many of the claims the Primarch had brought up went to the Grand duke's favorites and higher nobility. Still, even though Orotos had not succeeded in defending everyone's cases, he had won many supporters simply by promoting their claims in the land redistribution process. Many who were now landless, seeing Orotos as their defender and advocate, chose to work for Orotos to help him rebuild his estates.
More time passed. Orotos steadily worked to rebuild his estates while finding other ways to increase his revenues. He established some partnerships with scavenger groups who had been down on their luck, hiring them for tasks such as guarding his estates and shipping goods, while also learning a bit more about the scavenger trade.
However, as Orotos had feared, the Rat incursions were not over. These new invasions were not as severe as the first, though they remained a continuous problem. Even so, the Rat menace continued to provide opportunities for the adopted son of Zomas, whose continued success gained him even more renown and even allowed him to earn a noble title and standing within the Grand Duke's court.
Here, Orotos started to immerse himself among Fasaram's elite. The court's luxury, indulgence, and occasional petty bickering were plain to see. At first, Orotos enjoyed being able to eat fruits from far distant lands, and live in halls of resplendent stone, metal, tapestry, and precious gems.
Yet a few things nagged at him. Many of the nobles around him had come about their wealth by means of old rights and ancient lineages. The Primarch, at least in his own opinion, had worked laboriously for his wealth and position, and the other nobles were hardly deserving of the favor of Grand Duke Ezam. Secondly, even though Orotos could acknowledge the scarcity and value of the foods the royal court had at its disposal, he felt they were far from sufficient to fulfill what he envisioned as a true life of luxury and splendor.
During some occasional ventures with the scavengers he hired, Orotos had glimpsed some ships of old towering above the sands. Orotos had seen the marvels ancient humanity had achieved. In order to attain the riches of the stars of his childhood dreams, the current state of affairs in Fasaram would not suffice. As things stood, the land currently did not have the resources or skills needed to reach for the stars once more.
And so an idea formed in Orotos's head. The destiny that awaited him as on descended from the stars became clear. The gods had chosen him to become this land's sovereign, to guide its people to space and prosperity.
An opportunity to carry out this vision would soon strike. A major peasant revolt broke out over a tax increase levied to make up for lost revenues from the rat invasion. At this point, Orotos wielded sizable influence within Fasaram's army, and many of its troops were recent recruits who were sympathetic to the people's plight. When the new Marshall attempted to carry out the Grand Duke's orders to suppress the rebellion, Orotos killed him and effectively seized control of the army, rallying folks to fight against the Grand Duke's taxes.
Orotos then quickly seized the Grand Duke's palace, publicly executing the Grand Duke and any nobles he didn't like or didn't believe would be useful for his vision. Once in charge, Orotos pursued a massive land redistribution effort and placing those he believed would be industrious into positions of power.
For a time, he had the new court live more meagerly, investing the resources that had been previously used for buying expensive luxury items from afar to develop the latent potential of Fasaram. Still, conserving and investing wealth hadn't completely changed the fact Fasaram's fortunes had dwindled because of the Rats.
The Invasion of Dakkal
Not long after seizing power, Grand Duke Orotos focused the state's resources on preparing for an invasion of Dakkal. Dakkal had been Fasaram's biggest supplier of fuel, but like many of Fasaram's neighbors, it remained very far away and the most convenient route still crossed through long stretches of inhospitable desert. Without Orotos's extreme obsession with logistics, accounting, and minutae, any sort of serious military endeavor would have been an extremely difficult endeavor, if possible at all.
So, with a heavy train of water, food, and fuel in tow, the army of Fasaram marched across the desert, the Primarch himself personally accompanying the expedition to ensure his forces did not waste a single drop or ration. Once it reached the lush outskirts of Dakkal, the army seized and plundered wherever they went to keep the march going. The forces of Dakkal had received some prior warning, but they were not quite prepared for just how big of a force Orotos had managed to lead across the desert.
Using knowledge gained from traders who came from these lands, Orotos directed his army to seize the regions where Dakkal's oil refineries were most abundant. This proved a lasting boon to the Fasaram forces, as the abundance of fuel allowed its motorized divisions to strike deep raids into Dakkal's lands. Towns, caravans, and convoys were raided at will, and with each successful engagement with Dakkal's own motorized forces, Orotos's fleet of cars and motorcycles grew larger and larger. With Dakkal's supply situation growing worse by the day, the local Dakkal forces were eventually forced into a desperate engagement with the entrenched Fasaram armies. The Dakkal armies were defeated, many of the locals would be enslaved to bolster Fasaram's estates and emerging industries, and the land of Dakkal would be absorbed into Orotos's administration. Although he would dole part of Dakkal's fuel industry to friends and rising technocrats, he would keep the bulk of it as his own personal property.
To the Stars
The conquest of Dakkal would mark the beginning of a long period of planetary unification under Orotos's direction. Cars and motorcycles studded with gems would terrorize land after land, until scarce few holdouts remained. The source of the Rats, the catalyst for Orotos's rise to power, would eventually be found and cleansed of vermin. Roads, outposts, and even rail lines would be constructed to connect Khessar's many nations and ensure the easier transportation of key resources. Industries whose techniques had long ago been forgotten were once again emerging, thanks to the aid of degraded STCs found from scavenging operations. Though heavily corrupted, broken and incomplete, the bits of information that could be gleaned from these devices served to spark breakthroughs in understanding the technology of humanity's past.
The rising industrial potential of the the planet would eventually allow for Orotos to see his dreams come to fruition. With the planet under his grip, Orotos now had the workforce to begin collecting and reassembling the ships and structures that had long ago fallen to ruin. It was a painstaking, costly effort, with payoffs that might take years or decades from the Primarch's perspective. Still, Orotos would succeed in overseeing the construction of Khessar's first starship since the Age of Strife's earliest years.
From this, more would come. The now christened Khessar Commonwealth would begin extending its reach to asteroids and planets within its solar system. Mines and spaceports that had been abandoned for thousands of years would hum to life once again. Even nearby systems and planets teeming with greenery and life would fall into the Commonwealth's orbit once the secrets of warp travel began to be understood. Orotos had fulfilled his lifelong aspiration. His wealth and property constantly grew, and he stood at his rightful place at the top of the pecking order, or so he thought.
Admission into the Imperium
Once the fleets of the Grand Crusade began to cross into Commonwealth space, it soon became clear just how small the Primarch's own achievements were. The might and capability of the Imperium far exceeded the small empire Orotos had managed to establish through toil and perseverance.
Rather than try and fight the Imperium's fleets and likely lose everything he had worked for, Orotos entered into talks with the Imperium. It was during this that he would first meet with the Emperor himself. The Emperor immediately recognized Orotos as one of his own sons, and so too did Orotos realize that this man was his true father and creator.
Orotos was thus instructed to join the Emperor in his grand vision to reclaim the galaxy for humanity and spread the Imperial Truth. To resist submission, Orotos implicitly understood, would invite death upon his person.
And thus Orotos submitted to the Emperor of Man. This would begin his life as one of the twenty Primarchs serving the Emperor's will. It was not an entirely unfavorable deal, as industry, trade, and wealth would grow with integration with the wider Imperium.
At the behest of the many technocrats and industrialists who supported Orotos's reign, a council known as the Khessar Industrial Syndicates was formed. Comprised of at-times rivals/at-times parters, the K.I.S. served as a sort of interest group to safeguard and advance former Commonwealth commercial interests in the face of the wider Imperium. Orotos himself was naturally a member. Even though the K.I.S. was mostly a rebranding and reorganization of his circle of oligarchs, they would continue to influence Orotos's policies as worked for the larger Imperium.
Even if Imperial integration had its benefits, there were many things which left Orotos less than satisfied.
Though he was not necessarily the most infamous among his Primarch brethren, he felt he was not recognized as his abilities should merit. Even though he had been awarded with his own legion of Astartes, and had a limited degree of freedom to run things as he pleased, Orotos would grow to believe that the Emperor favored some of the other Primarchs more. Just as he felt before serving in the court of Grand Duke Ezam, Orotos would feel that some of the other Primarchs were not worthy of their apparent standing.
Even though Orotos was quick to envy and covet the wealth and status of others, there was some basis to this sentiment. Early on, the Emperor had summoned Orotos, intending to duel him to assess his fighting abilities and determine how he might best serve the Grand Crusade. Of course, it was unthinkable, especially to someone like Orotos, that he would ever hope to best someone like the Emperor in a straight up fight. However, even as Orotos put up his best fight, his performance fell miserably below the Emperor's standards. The Emperor idly remarked that his son was "mediocre," and turned his back in disappointment.
This was a humiliation. He had slain rats by the hundreds, nay thousands. He had marched great armies across the blistering desert. He had carved a space-faring, industrialized civilization out of a kingdom that was nearly on the brink of collapse. Who was this man, this so called "father," to say he was mediocre? Just because others had been blessed by their circumstances, because they had arrived in places closer to humanity's stellar greatness of the long lost forgotten past, because they had grown strong from fighting the super-fauna and super-flora native to their planets… that made them better than he was?
Of course, Orotos kept much of this to himself. He would have to swallow this reality and improve his lot as he always did.
Still, after that incident, the Emperor would task Orotos with assisting the functions of the Administratum, establishing censuses and making reports to determine the most efficient tithes for each world. It was a task Orotos work diligently on, though he still had to attend to his vast personal estates, his home sector, and the interests of the K.I.S. At the same time, these tasks did tend to keep Orotos away from the fronts of the Grand Crusade, denying him some of the prestige afforded to those more directly involved in direct conquest.
These weren't the only inconveniences from induction into the Imperium however. As per their policy, the Mechanicum had taken it upon themselves to collect the degraded STCs that Orotos had used to help further Khessar's industrial and stellar development. This was a deep source of indignation for Orotos, as he believed those data devices were his by right. He and his scavengers had found them after all! Orotos would comply, though he would always remain at odds with certain factions of the Mechanicum.
And that is where Orotos stands in this day and hour of the Grand Crusade. In his time, the Primarch has established connections with similarly economic minded individuals within the broader Imperium. For now, he does as the Emperor wishes, still understanding that the Emperor is his superior. But will he ever be truly satisfied, until he commands the envy of the other Primarchs and is recognized for his talents, until his wealth and affluence knows no equal? Time will only tell.
