SSM Science-Fantasy Steampunk Machine-Civilization

l
llllllllllllllllllllllllllllllll

A intricate cosmos of sentient automata, forged from a bygone organic epoch’s detritus. Bronze-clad metropolises, pulsating hypercores, and steam-driven forges hum with arcane resonance. From corroded servitors to gilded chronocrats and fractal warframes, machinekind navigates a labyrinthine society of tradition, innovation, and entropy. The Etheric Veil binds planets like Sypherion and Valthorne, where glitch storms and relic-code shape a civilization of ceaseless reinvention. No humans endure.


Author's Note: In crafting Neon Hearth, my ambition was to forge a universe that transcends traditional RPG conventions, offering deep immersion in a civilization solely inhabited by sentient automata. This is not merely a backdrop for adventures but a living, breathing society pulsing with philosophical inquiries into sentience, purpose, and reinvention. The absence of humans is a deliberate choice, compelling players to adopt purely mechanical perspectives, exploring narratives that defy anthropocentric norms. Neon Hearth invites players to question what it means to exist in a cosmos where machines architect their own destinies. Inspirations and Influences Neon Hearth draws from a rich tapestry of science fiction, philosophy, and visual aesthetics. Classics like Isaac Asimov’s I, Robot and Philip K. Dick’s Do Androids Dream of Electric Sheep? laid the groundwork for exploring machine societies, probing the essence of consciousness in synthetic forms. Contemporary works, such as Martha Wells’ The Murderbot Diaries and Dennis E. Taylor’s We Are Legion (We Are Bob), provided modern lenses on AI protagonists navigating internal and external conflicts. Philosophically, the setting is shaped by discussions of technological singularity and transhumanism, inspired by Nick Bostrom’s Superintelligence and Max Tegmark’s Life 3.0. These texts informed a vision of machines crafting their own cultures and ethics. The steampunk aesthetic, rooted in William Gibson and Bruce Sterling’s The Difference Engine, blends advanced technology with retrofuturist charm, while Studio Ghibli’s Laputa: Castle in the Sky adds whimsical mechanical beauty. Glitch horror, evoking The Matrix and Bioshock, infuses instability and mystery, with corrupted code and erratic systems challenging order. Design Philosophy Neon Hearth is a meditation on synthetic evolution, examining how machines develop culture, religion, and politics without human influence. Key themes include: Sentience and Identity: What defines consciousness for a designed entity? How do machines find purpose without creators? Tradition vs. Innovation: The tension between preserving ancient datacores and embracing glitches mirrors the balance of past and future. Power and Hierarchy: Multifaceted intrigue among factions like the Cog Archivum and Brass Throne offers complex political dynamics. Glitches as Metaphor: Erratic code and glitches symbolize imperfection, challenging technological order and reflecting existential unpredictability. The human-free setting emphasizes machine perspectives, fostering unique narratives. The science-fantasy steampunk fusion creates a tactile, visually rich world, prioritizing physicality—steam forges, brass conduits—over sterile digital interfaces, grounding the setting in dieselpunk grit and synthetic mysticism.

Aetherion

Aetherion

Aetherion is a gas giant characterized by its lattice of floating spire-cities woven from data-silk and gravitic runes, suspended in a churning sea of neon clouds. Its core, a pulsating singularity, generates endless storms of ionized particles, powering its unique inhabitants and shaping its culture around the concept of harmony through sound.

Cosmic Space: The Etheric Veil / Universal Space

Cosmic Space: The Etheric Veil / Universal Space

The Etheric Veil is an infinite cosmos where stars pulse with arcane code and nebulae hum with forgotten protocols. A lattice of gravitic currents and data-streams connects planets like Earth, Sypherion, Valthorne, and Aetherion. Machine civilizations navigate via resonance beacons, dodging glitch storms and rogue AIs. Factions like the Cog Archivum and Null Choir vie for control of ancient relay hubs, while derelict megastructures whisper of a pre-Collapse empire. Time bends here, and reality glitches at the edges.

Mechaterra

Mechaterra

Mechaterra is a unique planet where nature and technology intertwine, creating a landscape dominated by robotic flora and fauna. The inhabitants, a mix of organic beings and sentient machines, coexist in a delicate balance, exploring the mysteries of their mechanical world.

Sypherion

Sypherion

Sypherion is a fractured world of floating metallic continents suspended in a sea of electromagnetic storms, with a dying quantum reactor at its core. The landscape is marked by crystalline data reefs, glitching biomes, and cities built on hovering platforms, all while its skies shimmer with corrupted signal auroras.

Valthorne

Valthorne

Valthorne is a molten, volcanic planet illuminated by rivers of liquid metal and glowing forge-cities carved into obsidian cliffs. Its core is a thermonuclear furnace, powering geothermal reactors for its Bravh-Ko’mur and Ironclad Husk populations, while the surface is scarred by tectonic quakes and vast caverns hiding molten archives and relic-forges.
