Luna

Luna also known as simply as the Moon, or as Luna Regalia, is Terra's only natural satellite. And like most of the celestial bodies within the Sol System, Luna is littered with the ruins of humanity's Golden Age.
== Overview ==
In the modern era, Luna—Terra's sole natural satellite—has evolved into a densely populated and highly developed celestial body within the Stellar Imperium. Beneath the Lunar regolith, vast populations thrive in immense, intricately constructed cities forged from crystal and iron. These subterranean metropolises stretch far and wide, providing shelter and stability to the millions who call Luna home. Above the regolith, however, the landscape tells a different story. The Lunar surface appears as if it has been shattered by some cataclysmic event, crisscrossed by immense crystalline ionic fissures that snake across its observable crust. These cracks glow with a sickly yellow miasma, and for millennia have been harvested by the Lunarian Populi to fuel the cities of which they live.
In years past, during the Dark Millennia of the Long Dark, the Sol System was enshrouded by the ominous Stygian Veil. During this tumultuous era, Luna, like the rest of the star system, was irrevocably scarred by the encroaching Dark Ages. The inhabitants of Old Luna, known as the Lunar-Born, were driven to the brink of insanity. This descent into madness sparked millennia of civil wars and unending strife as the system around them devolved into chaos. Despite their internal conflicts, raiding fleets frequently launched from Luna, seeking bounty and plunder across the beleaguered star system.
In the midst of this anarchy, during the mid-millennia of the Long Dark, the Terran Moon was returned to its pre-terraformed state. This devastating reversal was caused by the fires of atomic salvoes that ravaged the Lunar surface, an act committed by a forgotten Terran Empire. This drastic measure was intended to bring an end to a long-forgotten Lunar-Terran interplanetary war, a conflict that had pushed the interwarring Lunar civilizations to the edge of annihilation.
Yet beneath Luna's shattered surface, the Lunarian Noble-Cistronic Houses have thrived for millennia, hidden away within the moon's lifeless core. These powerful factions have carved out vast, cruel kingdoms, built upon the gene-forged flesh of those too weak to resist their dominance. Over time, they have grown ever stronger, consolidating their power in the dark recesses of Luna.
Following the end of the Third Denarion War, the Denarion presence on Luna solidified through the establishment of the Geronymic Sons, a formidable faction that took root within the moon's depths. Additionally, there were once Illovdis World-Rider Aligned Denarion Secessionist Guilds on Luna, though these entities have long since faded into obscurity. It is widely believed that these guilds were either absorbed by the Lunarian Houses or assimilated into the ranks of the Geronymic Sons, leaving little trace of their original identity.

=== The Golden Age of Humanity ===
Like all celestial bodies within the Sol System, Luna was among the earliest candidates for human colonization. Its proximity to Terra made it an ideal first step in humanity's grand expansion into the stars. In the first centuries and early millennia of Mankind's Golden Age, Luna underwent a remarkable transformation, becoming a symbol of human ingenuity and determination.
Terraforming efforts spanned millennia, driven by the advanced archeotechnologies of the World-Engines and the relentless ambition of humanity. These immense machines, marvels of ancient engineering, worked tirelessly to alter Luna's harsh environment. They generated a breathable atmosphere, stabilized the climate, and transformed the barren Lunar surface into a hospitable environment capable of supporting human life. This massive undertaking required not only cutting-edge technology but also the collective effort and will of generations of settlers, engineers, and scientists dedicated to turning the dream of a thriving Lunar colony into reality.
During this transformative period, vast crystal and iron-forged cities were constructed beneath the Lunar regolith. These subterranean metropolises, protected from the harsh conditions of space, soon became home to millions of inhabitants. The cities were therein interconnected by an intricate network of tunnels and transport systems, allowing for efficient movement and communication across the Lunar surface. Above ground, solar collectors and energy farms harnessed the power of the sun, providing a sustainable energy source for the growing population.
As Luna flourished, it became a hub of scientific research, industrial activity, and cultural development. Universities, research institutions, and manufacturing centers dotted the landscape, attracting the brightest minds from Terra and beyond. The Moon's unique environment also made it an ideal location for experimenting with new technologies and innovations that would later be applied to other colonies across the Sol System.
The initial colony sites, established in the early days of exploration, rapidly grew into thriving cities. These nascent settlements, powered by a mix of determination and cutting-edge technology, quickly expanded their populations and infrastructures. And over the span of millennia, these bustling cities evolved into independent nations, each with its own distinct cultures and governance. Human ingenuity reshaped the once barren Lunar surface, transforming it into a vibrant landscape.
The vast, desolate plains of the Lunar mares, initially stark and lifeless, were meticulously converted into great oceans. Advanced terraforming techniques enabled the creation of these immense bodies of water, which soon teemed with deep-sea life. Scientists and engineers introduced carefully selected marine species, fostering new ecosystems that thrived in the artificially created seas. These oceans once not only provided sustenance and resources for the Lunar inhabitants but also aided in the regulation of the climate, contributing to Luna's newfound habitability. Simultaneously, the moon's surface saw the emergence of lush forests and expansive grasslands. Through a combination of genetic engineering and traditional horticulture, a variety of flora was cultivated, turning Luna into a green haven that mirrored the fertile lands of Terra. These verdant landscapes provided essential oxygen, food, and recreational spaces for the growing populations, enhancing the quality of life for all Lunar residents.
The transformation of Luna was a monumental achievement, showcasing humanity's ability to adapt and thrive in even the most challenging environments. The moon's cities, now self-sustaining and prosperous, became centers of innovation and culture. Universities, research facilities, and cultural institutions flourished, attracting talent and knowledge from across the quickly developing Sol System. The independent Lunar nations forged their own identities, contributing to a rich tapestry of Lunar civilization.
As Luna's ecosystems stabilized, the moon became a beacon of environmental engineering and sustainable living. The lessons learned from terraforming Luna were invaluable, providing a blueprint for future colonization efforts on other celestial bodies. The successful transformation of the Lunar mares into oceans, and the barren landscapes into thriving forests and grasslands, would stand as a testament to human creativity and perseverance in the following millennia. In this new era, Luna was no longer just a satellite of Terra; it had become a world in its own right, a testament to what humanity could achieve when faced with the vast expanse of space and the challenges it presented. 
As the Moon flourished, it became a beacon of human achievement and a testament to the transformative power of human terraforming efforts. Its great cities grew into marvels of architectural innovation, showcasing the ingenuity and creativity of their builders. These urban centers, with their towering spires and sprawling complexes, stood as symbols of progress and resilience. The top-side cities of Luna had become a blend of advanced technology and aesthetic beauty. Structures were designed to maximize space and efficiency while incorporating elements that celebrated the natural world and the hard-bought human efforts that were poured into it's design. Transparent domes and towering skybridges offered breathtaking views of the lush landscapes and vast oceans, creating a harmonious integration between the meticulously designed environment and the terraformed surface. Public spaces were once adorned with sculptures and gardens, blending art and nature in a seamless tapestry.
Transportation networks within these cities were a marvel of engineering. High-speed maglev trains and aerial tramways connected various districts, facilitating swift and efficient movement across the Lunar surface. Subterranean transit systems complemented these networks, ensuring that even the most remote areas were easily accessible. This intricate web of transportation not only enhanced connectivity but also fostered a sense of unity among the diverse populations of Luna.
As the Moon continued to thrive, it stood as a shining example of what humanity could achieve when united by a common goal. Its transformation from a barren satellite to a flourishing world was a testament to human perseverance, innovation, and the boundless potential of the human spirit. The successes of Luna's colonization consistently inspired further ventures into the Sol System and beyond. Each new achievement in terraformation was first tested and perfected on Luna, serving as a proving ground for humanity's expanding reach. As other celestial bodies were transformed into habitable worlds, Luna remained special, a symbol of human determination and technological prowess.
Luna's pioneering role in humanity's expansion into space was not just about technological milestones but also about the spirit of exploration and resilience. The moon's transformation from a barren, lifeless rock into a thriving, vibrant world was a testament to what humanity could achieve when driven by a common vision. It became the benchmark for subsequent colonization efforts, a model of success that other missions aspired to replicate. Innovations in energy production, environmental management, and urban planning that originated on Luna were later adopted on Mars, the many moons of Jupiter and Saturn, and even on planets in distant star systems. Luna's experience provided invaluable lessons in creating evermore self-sustainable habitats in ever-increasingly harsher environments, making it the cornerstone of human expansion throughout the cosmos.
Despite the spread of humanity to other worlds, Luna held a special place in the collective consciousness. It was the first and most prominent example of what could be achieved, a green jewel set against the backdrop of the dark, infinite expanse of space. Its lush forests, expansive oceans, and bustling cities were a source of pride and inspiration for many during this Golden Age. Luna's continued prominence also stemmed from its cultural and historical significance. It was here that humanity first set foot on another world, a milestone that marked the beginning of a new era of exploration. Monuments and museums commemorating this first of Man's Lunar achievements along with the Millennia worth of achievements that followed still dot the Lunar surface even into the Modern day, attracting Pilgrims and Imperial Historians alike regardless of the disrepair they have been left in. The stories of the early settlers, the challenges they faced, and their eventual triumphs were woven into the fabric of Lunar society, creating a rich tapestry of heritage and identity.
=== The Long Dark ===
But as with many paragons of human innovation, Luna's golden age would eventually come to an end. As during the Dark Millennia of the Long Dark, the Sol System was enshrouded by the cataclysmic Void-Storm known as the Stygian Veil. This tumultuous era left an indelible mark on Luna, just as it did on the rest of the star system, plunging it into the depths of the encroaching Dark Ages. With the inhabitants of Old Luna were driven to the brink of insanity during this dark age, this descent into madness sparked millennia of civil wars and unending strife. As the once-united lunar nations fractured into warring factions, each struggling for dominance amid the chaos. And as the Sol System around them devolved further into turmoil, Luna itself became a bitter battleground, its surface scarred by relentless conflict. Despite their internal conflicts, raiding fleets frequently launched from Luna, seeking bounty and plunder across the beleaguered star system. These fleets, driven by desperation and a lust for survival, preyed upon other colonies and trade routes, exacerbating the anarchy that gripped the system. Luna's reputation shifted from a beacon of human achievement to a symbol of despair and devastation.
In the midst of this ever-increasing era of anarchy, during the mid-millennia of the Long Dark, Luna was nearly returned to its pre-terraformed state. This devastating reversal was caused by the fires of atomic salvoes that ravaged the lunar surface, an act committed by a forgotten Terran Empire. This drastic measure was intended to bring an end to a long-forgotten Lunar-Terran interplanetary war, a conflict that had pushed the interwarring lunar civilizations to the edge of annihilation.
The atomic bombardment was a desperate gambit by Terra to quell the incessant lunar raids and to bring some semblance of order to the fractured worlds of the Inner-Rim of Sol. Much of the once-thriving oceans were either evaporated into the void or polluted with radioactive materials, forests were reduced to ash, and the once vibrant cities were buried under a blanket of radioactive dust. The lunar surface, once a testament to human ingenuity and perseverance, was transformed into a desolate wasteland, shriekingly echoing the horrors of its violent past.
The Lunar surface was effectively razed to the ground as now unnatural yellow light cracked through the regolith, signaling the end of an era. The grandeur that had taken millennia to achieve and the efforts of untold trillions were obliterated, transforming the surface into an apocalyptic landscape. This desolate expanse teetered between the pre and post-Golden Age, with only pockets of lush greenery surviving within hidden Lunar Basins amidst the devastation. Within these isolated oases, some lucky few Luna-Born continued to live as their forebears did, maintaining a semblance of their former lives as Lunarian Kingdoms dragged on into the Modern Era.
However, the vast majority of Luna's surface became barren once again, a lifeless wasteland. Yet, these dead-fields were not entirely devoid of life. They became home to wandering herds of saxumavorous wildlife, rock and crystal eating creatures that thrived on the rocky terrain. Following these herds were tight-knit familial units of survivors known as the Oserrel Clans, who eked out an existence on the dead-plains by hunting and harvesting the meat of these rock-eaters. These hardy clans embodied the resilience of the human spirit, adapting to the harsh conditions and finding ways to endure in the face of overwhelming adversity. Yet beneath Luna's shattered surface, a faction of eugenicist gene-wrights known as the Lunarian Cistronic-Houses thrived for millennia. Hidden away within the moon's lifeless core, these powerful factions of despotic scientists carved out vast, cruel kingdoms. Their societies built upon the gene-forged flesh of those too weak to resist their dominance. And over time, these Lunarian Cistronic-Houses grew ever stronger, consolidating their power in the dark recesses of Luna.
The Lunarian Cistronic-Houses were a formidable force, their kingdoms a labyrinth of laboratories and genetic foundries. They practiced advanced and often brutal forms of eugenics on those unlucky enough to live under their influence, continually refining and enhancing their genetic stock of both their Warriors and Workers to maintain their dominance. The weak were either subjugated or used as raw material for genetic experiments, ensuring that only the strongest and most adaptable thrived in their subterranean realms. These eugenicist overlords wielded immense power, their influence extending into every aspect of life beneath the lunar surface.
Despite the surface's devastation, these hidden kingdoms flourished, insulated from the chaos above. They developed advanced technologies and amassed great wealth, their power rivaling that of the greatest empires of old. And often, Cistronic Gene-Maesters would embark through the Sol System to either bring death and ruin to unlucky Nations across the breath of Sol's Worlds, or to divvy out their skills to those who could dole out either the coin or resources to patronize them. 
==== The Jovian Power Reallocation Period ====
During the Middle Years of the Long Dark, from mid-M73 to early-M75, after the conclusion of the Third Denarion War, the Sol System was in a constant state of flux. The power balance shifted continually, with the only constant being the Jovian Combine itself. With many Denarion Guilds being formed and dissolved during this period as the Jovian Combine reasserted its influence over the Sol System.
One guild, in particular, stands out for our purposes today: the Geronymic Sons. Officially a Denarion Guild, the Geronymic Sons were known for their eccentric, lavish, and exploratory nature, embodying the adventurous spirit found on Luna more than the predatory mercantilism of Jupiter's Denarion Children. The origin of their name is subject to much conjecture, but it is known that a group of Denarion Guild Veterans from the Third Denarion War found themselves marooned upon Terra's moon.
What transpired thereafter remains shrouded in much mystery, as few official records were kept. However, Lunarian myth speaks of men from the stars wandering through the Dead Fields. These star-men were followed by striding constructs of iron and glass, while steel whales flew without wings. This enigmatic procession from the stars wandered for many decades, enduring near-constant attacks from below led by the Cistronic-Houses. Men of Steel clashed violently with gene-forged Cistronic Beasts, their battles echoing across the lunar plains. Yet despite the relentless assaults, the star-men's procession extended into centuries, their silent march a testament to their resilience and determination.
The Oserrel Clans, nomadic tribes that roamed the Dead Fields, observed this long march closely. They watched as the star-men, their bodies made of metal and glass, slowly faltered under the dual pressures of the harsh lunar wastes and the incessant attacks from the Cistronic-Houses. These clans, adept at surviving in the desolate landscape, were fascinated by the star-men’s endurance. They whispered tales of these enigmatic travelers, who never ate and never drank, and who seemed to defy the very nature of the moon's deadly environment. Many of the Oserrel clans continued to follow these Men from the Stars, studying their seemingly and comparatively lavish and eccentric natures. Watching as they built intricate and ornate temple-like structures to their unknown Gods in the most unlikely of places. These Temples and Pyres were not just functional but also quite aesthetically captivating, with towering spires of glass and iron cut and forged from the ground that glowed in the dim lunar light. Gardens of bioluminescent plants and water features that defied gravity adorned their habitats, creating pockets of beauty in the otherwise desolate landscape of the Dead-Fields.
The Sky-Men's exploration even extended deep beneath the lunar surface, where they encountered the hidden kingdoms of the Lunarian Cistronic-Houses. Therein the Sky-Men's advanced constructs, powered by unknown technologies, often found themselves in brutal conflicts with the gene-forged beasts and hordes of the Cistronic-Houses. These battles were legendary, with tales of towering metal warriors clashing with monstrous creations echoing through the corridors of sprawling cave networks.
Many more Lunarian myths speak of these Star-Men, long since stranded and isolated, gradually adapting to their new environment and integrating into the culture of the Oserrel Clans. This integration began during a moment known as the Qvand Mon Skhir, a pivotal event in Luna's tumultuous history.
During a particularly intense battle between the Sky-Men and one of the Cistronic Houses' armies, the Oserrel Clans were unwittingly drawn into the conflict due to their unlucky proximity. As the Cistronic horde descended, the Oserrel found themselves fighting alongside the Sky-Men, their survival instincts and intimate knowledge of the Dead-Fields proving invaluable. Together, they pushed back the relentless gene-forged beasts and vat-born soldiers of the Cistronic Houses.
This unexpected alliance marked the beginning of a profound transformation. The Sky-Men, with much of their machines and armor in a state of disrepair from centuries of wandering and combat, found refuge and camaraderie among the Oserrel. Recognizing the resilience and adaptability of the Oserrel Clans, the Sky-Men began to share their advanced knowledge and technology with their newfound allies. 
Over time, the integration of these two groups led to the emergence of a unique hybrid culture. The Oserrel Clans, already adept survivalists, absorbed the martial prowess and technological expertise of the Sky-Men. This blend of traditions and skills created a formidable society capable of thriving ever more in the harsh lunar environment. The Oserrel, now bolstered with the might of the Sky-Men, developed new strategies and technologies to defend against the ever-present threat of the Cistronic Houses.
Socially, the integration fostered a sense of unity and mutual respect. The comparatively ancient stories of the Sky-Men's told of the distant world's of the Sol System and otherworldly battles that further enriched the Oserrel's cultural tapestry, while the Oserrel's deep connection to Luna and its cycles grounded the Sky-Men in their new home. Rituals and traditions evolved to reflect this shared heritage, celebrating both the past struggles and the hopeful future. The Oserrel Clans now marched through the lunar wastes in tandem with the men from the skies, who had become known to the Oserrel as the Jhyrikhar, or simply the Jhyrikh Men. These Sky-Men, sharing their advanced knowledge and technology, sparked a new exploratory spirit within many of the Oserrel. Together, they continued their wandering, cataloging much of the ancient ruins that made up Old-Luna.
The Oserrel and Jhyrikhar journeyed across the desolate landscape, uncovering the ancient skeletons of long-forgotten cities that had slowly risen from the sands of the regolith over the millennia. They explored the decrepit forges within the lunar southern mountains of Leibniz Beta, which eventually became the permanent home of the Oserrel Clans. And under the tutelage of the Jhyrikhar, the Oserrel learned to harness and adapt the advanced technologies that the Sky-Men had brought with them. As the centuries passed, the Oserrel Clans thrived in their new home, growing in strength and knowledge. They developed a deep respect and reverence for the Jhyrikhar, who had become their teachers and allies. The Jhyrikhar's advanced constructs, though deteriorating over time, were seen as symbols of divine power and wisdom. The cybernetic warriors of the Denarion Guild and their war machines became near-religious idols to the Oserrel Clans, embodying the fusion of human ingenuity and celestial might.
The Oserrel Clans, inspired by the Jhyrikhar, began to craft their own technologies, blending their survivalist instincts with the advanced knowledge imparted by the Sky-Men. They created hybrid machines and tools that were uniquely suited to the harsh lunar environment, allowing them to explore further and survive longer. These innovations included new forms of transportation, weaponry, and survival gear. The myths and legends of the Jhyrikhar became central to the cultural identity of the Oserrel Clans. Stories of bravery, unity, and shared struggle were passed down through generations, reinforcing the bonds between the descendants of the Oserrel and the long lived Jhyrikhar. These tales were told around campfires, in the shadows of the ancient ruins, and in the bustling workshops of Leibniz Beta, serving as a reminder of their shared heritage and collective strength.
As both the Jhyrikhar and their constructs continued to deteriorate, the Oserrel Clans took great care to preserve and honor these relics. They maintained the cybernetic warriors of the Jhyrikhar and their anciently potent war machines as best they could, incorporating them into their rituals and daily life. These relics served as symbols of the Oserrel's deep connection to their past and the enduring legacy of their celestial mentors.
Over millennia of tutelage, the Oserrel learned how to harness much of the technologies utilized by the Jhyrikhar and their own forefathers. They became adept at integrating the advanced knowledge of the Sky-Men with their traditional skills, creating a unique blend of innovation and heritage. The Jhyrikhar, now more machine than man, were able to rest upon their laurels, observing with satisfaction as the Oserrel expanded from the hearths of the lunar southern mountains of Leibniz Beta. 
The Oserrel, empowered by their newfound knowledge, forged their own armies of cybernetic warriors and war machines. These warriors, born from the union of human ingenuity and advanced technology, were a testament to the Oserrel's growth and strength. They stood ready to defend their lands and assert their independence against any threat that might arise. With this newfound power, the Oserrel continued to travel and explore the wastes just as their nomadic ancestors did. However, now they rode upon high-speed grav-bikes, wielding plasma rifles rather than traveling on foot with only their spears as protection. These grav-bikes, sleek and efficient, allowed them to traverse the rugged lunar terrain with ease, giving them the ability to cover vast distances in search of new knowledge and resources.
The Oserrel's mastery of technology enabled them to push the boundaries of exploration, venturing into areas of Luna that had long been forgotten or deemed too dangerous. They uncovered hidden caches of ancient artifacts and rediscovered lost cities, piecing together the fragmented history of Old-Luna. These discoveries fueled their sense of adventure and curiosity, driving them to explore ever farther.
Their expertise in both traditional survival skills and advanced technology made the Oserrel Clans formidable and versatile. They were adept at navigating the lunar wastes, finding sustenance and shelter where others would see only desolation. Their plasma rifles, powerful and precise, allowed them to defend themselves against the gene-forged beasts of the Cistronic Houses and any other threats they encountered.
The Oserrel Clans, now a thriving and dynamic society, continued to honor the legacy of the Jhyrikhar while forging their own path. They balanced the wisdom of the past with the possibilities of the future, always striving to learn and grow. The integration of the Jhyrikhar into their culture had transformed them, making them stronger and more resilient than ever before.
