Aeternum is a shattered archipelago where the remnants of divine war bleed into every spell, turning magic into a volatile, radioactive force that powers forgotten tech and fuels deadly rifts between worlds; its sky‑islands float above a mist‑shrouded Void Sea, each harboring factions—The Vigilants, The Severed, and The Seekers—locked in a desperate struggle over dwindling Ichor, the only true currency that can keep the fragile remnants of a once‑glorious utopia alive. In this post‑divine apocalypse, adventurers are both saviors and scourges, navigating treacherous sky‑lanes, battling sentient spells and Echo‑Stalkers, while a rogue AI known as the Arch‑Director seeks to re‑order the world by force, all under the watchful eye of a theocratic city perched atop the Spire of Oros, where the last living god is rumored to sleep, waiting to decide whether to heal or finish the world’s destruction.

World Overview

Aeternum is a "Post-Divine-Apocalyptic" setting. It features high magic that is currently unstable and forgotten high technology (magitech). The world has shifted from a unified, advanced utopia to a fragmented collection of sky-islands and isolated continents. What sets it apart is the Divine Fallout: magic is no longer a natural resource but the radioactive-like debris of a celestial war. Every spell cast or artifact used carries the echo of the gods' betrayal.

Geography & Nations

The world is a shattered archipelago floating above a turbulent, mist-shrouded ocean known as the Void Sea. The Spire of Oros: A massive, jagged pillar of rock where the last "living" god is said to reside; it is surrounded by a hyper-advanced theocratic city. The Rust-Wastes: A desert continent littered with the half-buried remains of floating cities and metallic constructs. The Iron-Root Isles: Heavily forested islands where the flora has mutated into bioluminescent, predatory forms, home to those who shun the old technology.

Races & Cultures

The old harmony is dead, replaced by survivalist friction: The High-Born (Elves & Humans): Often found in theocratic kingdoms, clinging to the belief that they are the chosen heirs of the sleeping gods. The Deep-Forged (Dwarves): Having survived the war in deep bunkers, they are now the primary "Artifact Hunters," treating ancient tech with a mix of religious awe and scientific rigor. The Changed (Orcs, Tieflings, & Mutants): Tribes living in the "Bleed" zones. They have adapted to corrupted magic and are often unfairly blamed for the Great War by the "purer" races.

Current Conflicts

The Scarcity of Soul-Fuel: The ancient artifacts and floating cities require "Ichor" (god-blood) to function, which is running out, leading to resource wars between guilds and kingdoms. The Awakening: Rumors persist that one of the betrayed gods is waking up—not to save the world, but to finish destroying it. The Null-Blight: A magical plague that strips creatures of their connection to magic, turning them into mindless "Husks."

Magic & Religion

Magic is residual energy from the Divine War. While anyone with the talent can tap into it, it is "unstable." Casting powerful spells near ancient ruins can trigger Arcane Anomalies. Religion is the driving force of politics. There are three main sects: The Vigilants: Worship the sleeping gods, hoping for their return. The Severed: Believe the gods were tyrants and seek to destroy all divine remnants. The Seekers: A guild-like faith that views the gods simply as "Level 20" entities whose power should be harvested and used as a tool.

Planar Influences

The Great War didn't just break the land; it tore the Planar Veil. Instead of distinct, separate planes, Aeternum experiences "Planar Bleed." The Rift-Walk: There is no easy travel to the Nine Hells or the Feywild; instead, "Rifts" spontaneously open, spilling extraplanar energies and creatures into the material world. The Astral Graveyard: The space between the floating islands is thick with Astral mist. Long-distance travel requires specialized "Void-Ships" that must navigate through the psychic debris of dead spirits and forgotten memories.

Historical Ages

The Age of Unity (The Zenith): A multi-millennial era of peace where magic and technology reached their peak. The floating cities and "Star-Gates" belong to this era. The Era of Discord (The Great War): A century of divine conflict that ended with the "Shattering." Most written history from this time was lost to magical fires. The Age of Silence: A dark age of total isolation between survivors. The Reconstruction (Current): The present day, defined by the rediscovery of the past and the struggle to claim its power.

Economy & Trade

Because travel is dangerous, trade is high-risk and high-reward. Currency: Standard gold is used, but the true "hard" currency is Ichor-Shards—small, glowing crystals infused with divine residue used to power light sources and heat homes. Trade Routes: The Sky-Lanes are the primary routes for airships, though they are plagued by "Aether-Pirates." Systems: A "Barter-Plus" system exists in smaller enclaves, while theocratic kingdoms use a strictly regulated central bank to control the flow of ancient artifacts.

Law & Society

Justice is local and often harsh. The Lex Divina: In religious kingdoms, laws are based on the ancient edicts of the fallen gods. Breaking a law is seen as a "sin" against the world's recovery. View of Adventurers: Society views adventurers with a mix of hope and deep suspicion. They are seen as "Tomb-Robbers" or "Chaos-Bringers" because their meddling with ancient ruins often triggers magical catastrophes. However, they are the only ones brave (or crazy) enough to find the resources needed for survival.

Monsters & Villains

The Echo-Stalkers: Horrific amalgamations of soldiers from the Great War, kept "alive" by corrupted magic, wandering the ruins in a state of eternal combat. The Heralds of the Void: A nihilistic cult that believes the Shattering was an act of mercy and seeks to "unmake" the remaining islands to find peace in the Void. Living Spells: Due to the unstable magic, some powerful spells have gained sentience and "hunt" in the wild, feeding on the mana of travelers. The Arch-Director: A rogue, ancient AI (a relic of the Zenith) that controls a legion of mechanical constructs, attempting to "re-order" the world by force.
