Aethenia

Aethenia is a high-tech, low-ambient-magic Steampunk dystopia. The world is centered on the immense Vertical City of Aethenia, powered by the volatile resource known as Éter. Society relies on brass and copper cybernetic implants for daily life. The unique element that sets us apart is Biomechanical Alchemy: certain advanced or damaged implants have 'awakened', manifesting abilities that defy science, such as magnetic field manipulation or accelerated self-repair. This technological 'magic' is now being corrupted by the Brass Plague (Virus), malware that not only causes mechanical failures but also steals the humanity, memories, and abilities of the infected, unleashing a civil war within the technology itself.

Aethenia is the sole nation and last refuge of humanity, an immense Vertical City that dominates the landscape. It is politically and geographically divided into three main tiers: The Aetherium (The Summit): The highest and most luxurious zone of the city. Home to the Old Royal Guard and the elite. It features clean air, sunlight, and is the center of governance. Access is strictly controlled by the Iron Conclave. The Gear (The Middle): The industrial and military zone. Headquarters of the House of Technology, Éter factories, and barracks. It is a labyrinthine network of steam pipes and brass walkways. The epicenter of production and, currently, of military quarantine. The Mist (The Bottom): The low, marginalized districts. A place of perpetual smog, pollution, and corruption. The home of the Mist Syndicate and a black market for Éter and cybernetics. This is the zone most affected by the Brass Virus. The Wastelands: Beyond the city limits, there is an unexplored and presumably hostile wasteland. It is the source of the Éter and the place from which rumors of the most dangerous Renegades originate.

Aethenia is primarily inhabited by Humans, whose culture and social status have been redefined by their relationship with Éter and Cybernetic technology. Racial differences are minimal, but the cultural and technological divides are absolute: The Ingenues (Aetherium Culture): The political and social elite. They dress extravagantly and often avoid visible cybernetic augmentations, considering them 'vulgar' or 'contaminating'. Their culture is based on secrecy, political intrigue, and control over the Éter. The Augmented (Gear Culture): The middle class: engineers, military, scientists, and administrators. They are the most dependent on and proud of their cybernetic implants, viewing them as essential tools for efficiency and order. Their culture values logic, discipline, and hierarchy. The Old Iron (Mist Culture): The laborers, smugglers, and resistance. They live in The Mist and have a culture of extreme survival. Their augmentations are often makeshift, repurposed, or stolen, and they proudly display their scars and gears. They are suspicious of authority and value street loyalty. The External Threat: The group known as The Renegades is not a distinct race, but individuals from any culture who have fully succumbed to the Brass Virus or adopted cybernetics to the point of losing their humanity. They are nomadic and represent the fate the city fears.

"The current crisis driving all adventure in Aethenia is the Brass Plague, a malware infecting and corrupting the population's cybernetic implants. The Cybernetic Collapse: The virus is causing violent malfunctions and the loss of humanity in the infected, who transform into dangerous, uncontrolled Renegades. No one in Aethenia can trust their own technology. The Tyranny of the Iron Conclave: The government of the Summit (Aetherium) has responded with brutal military quarantines in The Gear and The Mist. They are confiscating Éter and silencing dissident engineers from the House of Technology to hide the truth: the failure may be inherent to the system. Supply War: The Mist Syndicate has intensified the smuggling of purified Éter and unofficial implant repair kits. Clashes between the Syndicate and Conclave patrols are common in the lower-level passageways. The Secret of Alchemy: There is growing tension between the Augmented and the elite. It is rumored that Biomechanical Alchemy (the awakened powers of the implants) is the key to both the cure and the spread of the virus, making those with these powers targets or saviors."

"In Aethenia, magic, as known in folklore, is virtually non-existent. Instead, there is Biomechanical Alchemy, which is an unstable and unpredictable manifestation of Éter technology: How Magic Works: Biomechanical Alchemy occurs when a copper or brass implant, saturated by volatile Éter, 'awakens' or enters into resonance with the host's will. It is a process more akin to an engineering failure than a spell. Users: Only the Augmented (those with significant cybernetic implants) can be users, and it is a rare and uncontrollable phenomenon. Powers manifest tied to the hardware (e.g., manipulating magnetism with a mechanical arm, or overloading an optical eye to see the near future). Religious Influence: Aethenia is a fundamentally secular and technocentric society. The closest 'religion' is the faith in Science and the veneration of the Great Engineers who built the city, especially the original Inventor King. Organized religion is suppressed or viewed as mere superstition, especially by the Iron Conclave."

"Aethenia's history is divided into two key eras, with a veil of mystery over the prior civilization: The Void Era (Before Aethenia): A lost civilization that existed before the Vertical City. It is believed this era ended in a global ecological disaster (perhaps from the misuse of Éter or older technology) that rendered the surface uninhabitable. The only relics are highly complex Mechanical Ruins buried in The Wastelands, which hold the key to the Brass Plague. The Founding Era (The Builder): Led by the Inventor King, this era saw the creation of Aethenia as a self-sufficient ark-ship, built to raise humanity above the Void. The principles of Éter technology were defined, and the first mass cybernetic implants were installed. The current Conclave's culture is obsessed with 'restoring' this idealized era. The Stasis Era (Current): The era of decay and social division. It is the long period of stagnation where the city stopped growing vertically, focusing only on system maintenance. The power imbalance between the Summit (Aetherium) and the Bottom (The Mist) became absolute, setting the stage for the current Brass Virus crisis."

"Aethenia's economy is dominated by strict mercantilism, controlled by the Iron Conclave. Currency and Value: The official currency is the Brass Credit, though its real value is based on the availability of Éter. Éter is not only the fuel but the energy source that gives value to everything: from bank credits to the health of the augmented themselves. The Conclave monopolizes Éter, fixing its price artificially high. Smuggling Routes (The Mist): Main trade occurs through regulated air routes controlled by the Conclave and ground routes of pipes and passageways through The Gear. However, the Mist black market is the most active. This is based on the Smuggling of Purified Éter, unregistered cybernetics parts, and Plague Fixers (illegal healing kits for implants). Economic Division: The elite in The Aetherium engage in high finance and Éter speculation. The Augmented in The Gear work under a system of quotas and controlled wages. The Bottom (The Mist) subsists primarily through illegal trade and the bartering of services and hardware."

The main physical threats in Aethenia are not fantastic beasts, but human beings corrupted by technology: The Renegades (Monsters): Inhabitants who have fully succumbed to the Brass Plague. Their cybernetic implants malfunction, making them incredibly strong, fast, and violent. They act as a technological 'zombie horde,' seeking Éter or hardware to quench their corruption. They represent the threat of close combat and virus spread. The Designer (The Main Villain): The virus is not natural. It is the result of sabotage by an elite engineer or a dissident scientist from the House of Technology, known only as 'The Designer' (or 'The Brass Philosopher'). This villain seeks to expose the weaknesses of the Conclave and perhaps initiate the next phase of human evolution by the forced fusion of machine and mind. The Brass Squad (Conclave Antagonists): The military police units of the Iron Conclave, heavily trained with robust Éter augmentations and armor. They are the most common antagonists players will face in the Mist and the Gear. They operate ruthlessly to contain the virus, often executing the infected and those who stand in their way, regardless of guilt."
