Acheron Prime
Acheron Prime is the crown jewel of the Acheron System. The planet is covered in sprawling cities, with New Arkham being the most notable. Despite efforts to control environmental damage, the atmosphere remains highly polluted, necessitating atmospheric processors to maintain breathable air in certain regions. As the center of corporate power and intrigue, the planet is a melting pot of cultures, filled with towering skyscrapers, megacorporation headquarters, and seedy underworlds.
Geography
Acheron Prime is a world where nature struggles to assert itself against the relentless march of urban and industrial sprawl. The planet is defined by its three continents—Dis, Erebus, and Hestia—each bearing the weight of its own unique history and geography. Dominating the planet’s surface are sprawling mega-cities like New Arkham, Blackreach, and Ironclad City, each a labyrinth of towering skyscrapers, neon-lit streets, and bustling urban life. These colossal urban centers are interconnected by expansive networks of suspended highways, magnetic rail systems, and skyways, teeming with vehicles and pedestrians in constant motion.
The continent of Hestia, home to New Arkham and Blackreach, is the epicenter of Acheron Prime's urban civilization. New Arkham stretches endlessly with its corporate towers and labyrinthine alleys, while Blackreach descends deep into the earth, a subterranean mega-city of industry and intrigue. The Ironspine Mountains and The Iron Wastes, scarred by centuries of exploitation, lie on Hestia’s outskirts, reminders of the planet's natural past.
On Erebus, Ironclad City dominates the harsh industrial landscape, surrounded by military complexes and weapon manufacturing facilities. The continent’s surface is marked by massive fortifications and sprawling factories, standing in stark contrast to its desolate terrain. Meanwhile, the continent of Dis remains wild and untamed, with the Hellspire Mountains looming ominously over its inhospitable expanse. This uncolonized region resists humanity’s grasp, its geography dotted with dangerous anomalies and ancient ruins.
Across the planet, remnants of Acheron Prime's natural geography—once home to vast rivers, forests, and mountain ranges—have been transformed or erased entirely. Rivers have been redirected into underground reservoirs, mountains have been mined hollow, and the natural ecosystem has been replaced by polluted wastelands and artificial "green zones." The surviving wilderness, particularly on Dis, serves as a haunting reminder of what was lost, while the mega-cities and industrial zones dominate the horizon, leaving little space for untouched nature.

Ecosystem
Acheron Prime's ecosystem is entirely manufactured and regulated by human hands. The environment has been so heavily altered that the planet can no longer sustain life without artificial intervention. The atmosphere is tainted by centuries of industrial activity, necessitating atmospheric processors in key urban areas. Outside these controlled zones, air quality plummets, and the tainted atmosphere can cause sickness or death.
The artificial ecosystem within cities comprises genetically modified plants that can survive the high pollution levels, as well as domesticated animals bred to thrive in confined urban environments. Pigeons, rats, and stray cats dominate the streets, while corporate parks feature engineered flora designed to clean the air and provide greenery amidst the industrial chaos.
Interactions between biological organisms and the physical environment are minimal in the wilds of Acheron Prime. The cities are teeming with life, but much of it is artificial or heavily regulated to prevent uncontrolled proliferation. The original native species that once thrived here have been mostly wiped out or displaced by the relentless expansion of human habitation and industrialization.
Ecosystem Cycles
Seasons on Acheron Prime have become little more than a scientific footnote, as the planet's natural cycles have been disrupted by urbanization and industrial pollution. The planet once had distinct seasons, but now, the weather is primarily dictated by industrial and urban waste, causing artificial changes in climate rather than natural cycles.
Winter storms and acid rain are common in areas outside of the domed cities, where pollution levels are high. Many urban animals and modified plants have adapted to these erratic conditions. Creatures like rats and pigeons breed throughout the year with little regard for traditional seasons, thriving in the artificial heat generated by the cities. The planet's ecosystem cycles are thus chaotic, unpredictable, and closely tied to the rhythms of urban expansion and industrial waste production.
Localized Phenomena
One of the most striking localized phenomena on Acheron Prime is the Neon Aurora, an artificial aurora created by the concentrated pollution and industrial byproducts in the upper atmosphere. This dazzling light display illuminates the night sky with shifting hues of neon green, blue, and violet, reflecting the planet's highly urbanized aesthetic. While beautiful, it serves as a constant reminder of the environmental degradation that plagues the planet.
Another phenomenon is Smog Storms, particularly dangerous in the more industrialized zones. These storms are massive clouds of toxic smog that descend on the landscape, choking the air and reducing visibility to near zero. Citizens are forced indoors, and air filtration systems are pushed to their limits. The phenomenon is a direct result of unchecked industrial emissions mixing with the planet’s erratic weather systems.
Climate
Acheron Prime’s climate is heavily influenced by the massive energy output and pollution generated by its urban and industrial centers. Temperatures tend to remain relatively stable year-round due to the constant activity in the mega-cities, but extreme heatwaves can occur when industrial waste heat builds up. Outside the cities, in the desolate wastelands, temperatures swing wildly between scorching heat during the day and freezing cold at night.
The climate inside the domes is controlled by artificial means, keeping the air relatively clean and the temperature comfortable. However, beyond the cities, where nature has been irreparably damaged, the climate is unpredictable, and acid rain, smog storms, and dust storms frequently batter the abandoned industrial areas.
Fauna & Flora
The flora of Acheron Prime is almost entirely composed of genetically modified species, engineered to thrive in a polluted environment. Trees with metal-resistant bark and air-purifying plants are commonly found in corporate parks and green zones, while natural vegetation has all but vanished in the wild areas of the planet.
Fauna includes urban-adapted species such as rats, pigeons, and other animals that have learned to live off the refuse of the cities. These animals have adapted to the pollution and waste that pervade the urban environment, with some species developing resistance to toxins. Mutated animals also exist, usually in the abandoned industrial zones, where the combination of radiation and toxic chemicals has caused strange evolutionary adaptations.
Natural Resources
While most of Acheron Prime’s natural resources have been depleted or heavily exploited, the planet still holds valuable minerals beneath its surface, particularly rare metals that are essential for manufacturing advanced technology. These resources are often extracted by mega-corporations using vast mining operations that scar the planet's surface.
Water is a highly regulated resource on Acheron Prime, with most fresh water coming from underground reservoirs or imported from other systems. The planet also relies heavily on imported food and materials due to the scarcity of natural resources remaining on the planet itself.
History
Acheron Prime was once a lush and vibrant world, but centuries of industrialization and urbanization transformed it into a sprawling, polluted hub of commerce and corporate power. Initially colonized for its rich natural resources, the planet quickly became the center of massive industrial growth. Over time, the planet's cities merged into mega-cities, and its natural landscape was devoured by urban sprawl.
With the loss of the Sol System, Acheron Prime took on even greater significance, becoming the de facto center of humanity’s remaining power. The city of New Arkham emerged as the heart of political, economic, and corporate activity in the galaxy, and the planet's history is now one of rapid technological advancement, environmental degradation, and corporate dominance.
Tourism
Despite its grim industrial nature, Acheron Prime attracts a certain class of tourists—those looking to experience the heart of human civilization and corporate power firsthand. Corporate executives, off-world dignitaries, and thrill-seeking travelers come to experience the towering heights of New Arkham, the neon-lit streets, and the planet’s infamous nightlife.
Corporate tourism includes guided tours of advanced technological marvels, such as mega-corporation headquarters, towering industrial complexes, and domed luxury parks. The Neon Aurora is also a draw for tourists, providing a unique and beautiful spectacle in the night sky. Visitors often stay in luxurious corporate hotels located in the green zones, with all amenities and advanced security provided for their comfort.
Tourists are warned to stay within designated areas, as the industrial zones and wastelands are dangerous and heavily restricted. Despite its hostile environment, Acheron Prime offers a glimpse into the center of power in the galaxy—a place where wealth, corruption, and ambition collide beneath the glow of neon lights.
