The premise
The Shattered Sky of Aethelgard is a world where the ground broke apart an age ago and the poisoned surface was abandoned to fog and rot. Humanity lives aloft now, on a thousand floating sky-islands held up by aether-crystal, and the only way between them is the airship: brass-hulled, steam-and-aether-driven, sails of treated silk catching the high winds. You are an aeronaut beginning a hired hand - a deckhand on a tramp freighter, a sky-pirate's gunner, a fast-cutter courier, or a discharged navy airman with a debt - and a working ship is the only freedom that matters.
The Aether Cartel, under the silken Director Cassian Vark, controls the refining of the fuel every ship burns and would rather own you than fight you. The Navy of Highholm, led by Commander Solan Verrick, means to bring the crown's law to skies that have known none for a generation. The Free Fleet of sky-pirates - captains like Jek 'Grit' Corvan and the privateer Marnie 'Cloudsplitter' - prey on Cartel convoys and answer to a fraying code. The Cogwright Guild under Master Forger Brennan Coggs keeps every ship in the sky flying, for a price. And the Cult of the Fallen World preaches that the Shattering was judgment and the surface must be returned to.
An old prospector's chart has surfaced in the free port of Brasshaven, pointing to a lost pre-Shattering sky-island and an aether-vault that could shift the balance of the entire sky. Now every power is racing for it. Every port remembers the flag you flew in under, and every crew collects the share you promised.
What this world plays like
Your first ten turns are a berth, a crew you do not yet command, and your first cargo or first prize. You drink in Brasshaven, you cross a captain or court one, you learn which sail on the horizon is a friend and which is the gallows. The sky is already keeping the ledger.
By turn fifty your standing with the Aether Cartel, the Navy of Highholm, the Free Fleet, the Cogwright Guild, and the Drifters is tracked as real attitude, and the share you promised your crew on turn nine decides whether they follow you into the next storm. The Cartel agent you crossed remembers. The lost-vault chart has hardened into a heading.
By turn one hundred the sky is openly at war over the vault and you have a ship and a name of your own, or a debt that has come to collect. Whoever you crossed, whoever you sailed for, Aethelgard keeps the account - and a crew always collects what it is owed.
The Shattered Sky does not reset between sessions. Close the tab. The high winds are still blowing.
Factions in motion
The Aether Cartel
The ruthless corporate monopoly controlling the refining and distribution of all aether-fuel. The Cartel's Directorate prioritizes profit above all else, secretly suppressing the truth of the Great Rupture to protect their power and driving the world's ecosystem to a breaking point with their reckless exploitation.
The Navy of Highholm
The formal military and political power of Aethelgard's aristocracy, enforcing the King's Law from their fortress-island. The Navy struggles to maintain the old order and the security of the charted sky-lanes, caught between their dependence on Cartel fuel and the rising tide of piracy and fanaticism.
The Cult of the Fallen World
A nihilistic death cult that worships the Miasma below, believing the sky is an unnatural prison. Adherents, known as 'Grounders', commit acts of terrorism to destroy aether-tech, seeking to force humanity's 'purifying' return to the poisoned surface. Their whispers of a final, silent fall are spreading among the desperate and dispossessed.
The Drifters of the Unmoored Fleet
A nomadic confederation of salvage clans who live and die aboard their multi-generational ships in the vast wreckage fields of the Drift. Possessing unparalleled knowledge of the sky's secrets and dangers, they are the first to notice the changing, increasingly coordinated behavior of the sky-leviathans.
The Cogwright Guild
The insular and pragmatic union of engineers and artisans who build and maintain all of Aethelgard's technology. They mint the common currency from their forges in Brasshaven and jealously guard their schematics, selling their innovations to any faction with enough brass to pay.

Places that matter
Highholm Reach
A cluster of majestic, flat-topped islands, their verdant plains dotted with aristocratic spires and manicured estates. The capital city of Highholm gleams with brass and polished stone, its sky-docks bristling with the cannons of the Aeronautical Navy. The air is clean, the law is iron, and the poverty is kept carefully out of sight.
Brasshaven Chain
A chaotic tangle of dozens of smaller, forest-covered islands, all chained and bridged together with a century's worth of scrap metal and desperation. The 'city' is a grimy, bustling riot of workshops, taverns, and black markets, perpetually shrouded in smoke and the roar of engines. This is where fortunes are made, ships are fixed, and throats are cut with equal frequency.
The Sunderlands
A vast, sparsely populated expanse of rugged, mountainous islands and windswept plains. This is the frontier, home to independent aether-prospectors, hardy homesteaders, and those wishing to escape the notice of the major powers. The winds here are unpredictable, and settlements are small, fortified affairs against the elements and sky-beasts.
The Drift
A massive, slow-moving vortex of atmospheric currents filled with the wreckage of centuries. Broken ships, shattered chunks of pre-Rupture cities, and the skeletons of leviathans are all caught in its grasp. The entire region groans with the sound of grinding metal, and navigating its shifting reefs is a deadly art.
Cinderfall Approach
The sky here is perpetually stained orange-grey with the smoke from the Aether Cartel's primary refinery, Cinderfall. The platform itself is a colossal, fortified structure built onto a barren, mineral-rich island, surrounded by a fleet of tankers and armed patrol ships. The surrounding smaller islands are strip-mined and desolate.
The Boneyard Reach
A fog-drowned region of low-hanging, jungle-choked islands close to the Miasma. This is the prime hunting ground of the sky-leviathans, whose colossal skeletons lie draped over many of the islands, giving the region its name. The air is thick, visibility is poor, and compasses are known to spin wildly due to strange magnetic interference.
A real turn from this world
Director Cassian Vark does not rise from his chair on the Cartel platform at Cinderfall. "I sell the fuel that holds your ship in the air and the fuel that holds this city off the surface," he says, pouring two glasses you did not ask for. "So when I tell you the Brasshaven chart leads somewhere I would prefer it did not, understand that I am offering you the kinder option." He slides a contract across the brass. "Bring it to me. For a price you will not like, and a loyalty you will like less."
Out past the viewport, Commander Verrick's frigate sits at anchor, and somewhere a Free Fleet captain is already asking whose coin you took.
Standing with the Aether Cartel: pending. The deal is logged. In the Shattered Sky, every flag you fly under is remembered by the ones you didn't.
Why Skies of Brass holds up over a long campaign
Most AI roleplay tools are built around a single session. They start to fall apart at hour ten and are barely playable at hour fifty. Skies of Brass doesn't, because the world isn't living in a chat history - it's living in a database.
Mechanical truth in Postgres. Coins, inventory, NPCs, factions, locations, properties - all in real database rows. The narrator describes around the database; the database is what's true. By turn 500, your business ledger still balances and your apprentices still have the names you gave them.
Hierarchical chapter compression. Every chapter compresses into a tight summary; summaries compress into act-level summaries. The hundredth turn can pull a relevant detail from chapter two without flooding the context window.
Semantic memory. Important moments are embedded as vectors. When the current scene references an old promise, the engine retrieves the exact exchange where that promise was made - even 800 turns ago.
