A volcanic world tidally locked to its sun. Only a thin equatorial band is habitable. Stone is forged into nearly everything. Forests are rare; cave systems are everywhere.
Earth's 12 ruling Houses poisoned the planet beyond saving. In 2271 they launched a colonisation fleet for the stars. Three Houses — Jodon, Reubo and Ephrati — settled three different worlds. Years later, a strange signal led each of them to a single planet rich in resources and ancient ruins: Taurion.
The fall of Earth, the flight of the Houses, and the long sleep between the stars — the full saga, as it has been carried down to the colonists of Taurion.
Over the years the governments of the Earth became increasingly hostile and fractured. Alliances were formed and broken. Eventually 12 factions emerged in a semi-stable world order (or houses as they are now known). By this time the scale of weaponry available to the 12 factions was too powerful to use without exterminating all life on Earth. Consequently, when WWIII erupted, it wasn't a kinetic war. It was an information and propaganda war that lasted well over a century. Intelligence agencies had taken over news and entertainment and shut down free speech entirely. Every piece of information, or rather disinformation, was curated. Nobody knew what was true or what was false.
The absence of a meaningfully informed population left the megacorporations free to do as they pleased. With regulatory capture, they simply pushed through laws and regulations that benefited them and their shareholders in the short term. The constant flux of "truth" in the disinformation campaigns made long term planning nearly moot, and also made it easy for the megacorporations to create and push their own narratives.
Environmental standards were dismantled, and all laws regarding genetic engineering were erased. Biotech companies produced ever more genetically modified plants and animals that required ever harsher pesticides, herbicides, and stronger antibiotics.
Slowly the Earth was poisoned. Superbugs became more common, wiping out millions of people, nevermind the costs to domestic animals and wildlife. GMO plants became invasive species, destroying pristine environments and disrupting ecosystems. People became sicker and sicker as agro chemicals poisoned their water supplies while fisheries suffered as the lakes, rivers, and oceans were poisoned. Species were going extinct at alarming rates.
Eventually there was a crack in the social world zeitgeist and people began to reject government and corporate narratives that were clearly the opposite of reality. Mass protests turned into riots that were mostly crushed by government forces and private security forces hired by corporations. But for every casualty, the movements attracted 10x more people.
Behind the scenes the intelligence agencies ramped up misinformation campaigns against each other, blaming other factions for domestic and international problems. Following suit, the megacorps began environmental campaigns to support protesters against their competition.
Social cohesion in large urban centres was breaking down. Logistics chains for food, fuel, and consumer goods were crumbling. Protests got bigger and bigger and spilled over into suburban areas as well and degenerated into city-wide riots and looting.
Peak violence happened when the Jodon faction launched a limited nuclear strike against the Tydroid corporation's main production city, Berlin, in order to satisfy public outcry that was flamed by a disinformation campaign from the Yonic corporation, Tydroid's largest competitor.
Rather than continue the violence on Earth, the various factions and megacorps launched strikes against each other's satellites in order to disrupt communications and push their own narratives.
The situation had become desperate, and in 2247 the 12 factions formed a discussion group called "The Houses" to bring an end to the worldwide violence. For several years they debated and discussed, until in 2251 they arrived at the conclusion that they'd all failed humanity, and that the Earth was doomed, poisoned beyond the point of no return. They would need to head for the stars if mankind were to survive.
Building starships to transport colonists would take 20 intense years, but not everyone would get to go.
Selection of people who would go to the stars took place under the authority of the technetronic elite in the 12 Houses. Only the best and brightest would have a seat reserved for them and their families. Billions would be left behind on the poisoned, dying Earth.
As the selections progressed, it became increasingly apparent to those that would be left behind that they weren't going to be chosen. Human rights protests across the planet turned into full scale riots with many casualties. The world was thrown into chaos and society began to break down (even more).
But for the colonists all that was left behind. They would drift into cryosleep for a seeming eternity only to wake up as if no time had passed. There would be weeping as some cryopods had failed during the long journey, leaving only crusty bones and ashes where a living human should have been.
Three of the 12 Houses, House Jodon, Reubo and Ephrati, would colonise planets in 3 nearby solar systems in a distant sector of the galaxy. The fates of the other 9 Houses are unknown.
Before Taurion, each House carved a civilisation from a world that would have killed lesser peoples. Their home worlds shaped them — and the fleets they would one day send to the stars.
A volcanic world tidally locked to its sun. Only a thin equatorial band is habitable. Stone is forged into nearly everything. Forests are rare; cave systems are everywhere.
97% covered in water. Land is scarce, life is built on rafts, archipelagos and seasteading. Innovation in ships, hydraulics and aquaculture is unmatched.
Lush, green and overflowing with life — including predators and poisonous flora. Metal alloys are scarce; biomass and plant fibre fuel everything from buildings to vehicles.
A transmission no House could decipher. A planet beyond their wildest hopes. And a single word carved in an old Earth tongue.
Several years ago a strange and indecipherable signal was received. It was clearly created by intelligent life and was traced back to a planet orbiting a nearby brown dwarf star. Speculation was rampant. What or who created it? What did it mean? What did it say? Each House prepared small scouting missions to investigate.
Initial reports were impressive. The planet was rich in natural resources beyond anyone's hopes. The Ephrati expedition discovered an ancient tower disappearing into the clouds, its walls covered in strange symbols — and one phrase carved in an old Earth tongue: "Taurion." Other ancient ruins would soon be found scattered across the planet.
Back home each House prepared to send people to Taurion. Excitement was high and people eagerly began training for the challenges that would await them.
Each House answered the signal and planted a capital among Taurion's ancient ruins — the cities you spawn from, supply and defend.
Where House Jodon's landers first touched Taurion they seized an ancient ruin for their own and named it Vostok's Reach, in honour of the Baron. Its Command Centre is less a seat of government than a fortress — a slab of cast stone raised over alien foundations and ringed by the indestructible obelisks of the old city, which no siege has ever cracked.
Enter House JodonHouse Reubo surveyed Taurion for a full year before breaking ground. Their city — New Concord — is laid out on a strict grid around a cluster of ancient towers, every depot, refinery and barracks assigned its place by committee long before the first foundation was poured.
Enter House ReuboIt was an Ephrati expedition that first read the word Taurion from the face of an ancient tower, and it is at the foot of that same spire that House Ephrati raised Freeport. No two streets agree; the city sprawls outward from the tower as fast as prospectors can stake their claims — a churn of markets, workshops and holotainment rigs that never sleeps.
Enter House EphratiResource-rich and scattered with the towers of a vanished civilisation, Taurion is the world three Houses crossed the void to claim. Now its fate rests with those who answer the signal.

A whole country of contested ground — roughly the size of Northern Ireland, about half of Belgium — and every hex of it lives on-chain.
Pledge to the warlike Jodons, the logical Reubos or the entrepreneurial Ephrati — then study the fleets, buildings and resources that will carve your empire from Taurion.
