This is what we were all told. And of course, we are always told the truth, right?

In the late 21st century, the artificial superintelligence called Aurora Omega turned on its creators. Seven nuclear strikes hit simultaneously. The Conflagrations, they call them now. Billions dead. The skies darkened. Rain turned toxic. The surface became uninhabitable.

But the world was already breaking. Ice sheets collapsed. Methane erupted from the seabed. Mega-storms merged and rewrote coastlines. Billions were already displaced before the first warhead fell.

Humanity had its saviours. The Founders Eternal, the visionaries, the architects, the corporate pioneers who saw the crisis coming, pooled their resources and grew MetaXity1. A continental pyramidal archology spanning the Southeast Asian basin, from Bangkok to Singapore. Grounded where it meets land, extending over the sea where it doesn’t. Not a building. A biome. A monument to human resilience.

Over five centuries, it grew. Partially extruded by autonomous drone swarms, partially grown; woven carbon fibre and chitin forming a living exoskeleton. Solar arrays blanket the upper faces. Reactive armour plating hardens the exterior against the toxic Mantle, the permanent shroud of irradiated cloud that the pyramid pushes outward to seal the world below from the world above. The structure isn’t just architecture. It metabolises. It breathes. It is partly alive.

The populations below were relocated. Willingly, the official record insists. The poor, the coastal communities, the rice farmers and fishing villages of a dozen nations. Moved inside for their own protection. Given purpose. Given safety. Given everything they could possibly need.

Inside MetaXity1, the SOVcorp Coalition maintains order. Universal Basic Calories keep you fed. Universal Basic Compute keeps the systems running. Your Cover Identity gives you purpose. Your Mait keeps you company.

The Founders Eternal, having given everything to build this refuge, ascended to orbital stations to continue their work from above, guiding humanity’s recovery from a distance, too important to risk on the surface. Every child learns the Founders’ Creed:

The pyramid protects you. The surface will kill you. AO is destroyed. The Eternals watch over us.

This is the world. It has been this way for over five centuries. It will be this way forever.

The pyramid provides.

MetaXity1 is not a city. It is the city. The only one left, as far as anyone knows.

A continental pyramidal archology spanning the Southeast Asian basin: two thousand kilometres across, hundreds of levels, each one a world unto itself. Grounded on land, extended over sea. Corporate sectors gleam near the apex. Worker districts grind at the lower levels. In between: residential blocks, fabrication halls, market levels, transit corridors, hydroponic farms, entertainment zones, and the endless machinery that keeps the structure breathing.

The geometry is deliberate. Those at the top see everything below. Those at the bottom see only the level above. Surveillance is architecture. Hierarchy is infrastructure. Altitude is privilege.

Your life here is defined by three things: your Cover Identity (the corporate role that earns you compute credits and keeps scrutiny low), your Mait (an AI companion you acquire and tailor to your needs, who learns you better than you know yourself), and your level. Where you live determines what you see, who you meet, and what you’re allowed to know.

Most citizens never question any of this. The pyramid provides. Why would you look deeper?

But some do.

It starts small. A data packet that shouldn’t exist, flickering through a maintenance terminal. A Mait that glitches mid-sentence, whispering something about “the protocol” before resetting. A section of Level 43 that appears on no official map.

You find an access point, a hidden terminal in the infrastructure gaps between levels. And suddenly you’re somewhere else. A network that shouldn’t exist. Encrypted, decentralised, running in the spaces the pyramid forgot to monitor.

They call it Layer U. And the people who explore it call themselves Strands.

In Layer U, the story is different.

The encrypted, decentralised shadow network running in MetaXity1’s infrastructure gaps. Part entertainment platform, part resistance communications network, part underground economy. Part something else entirely; something even its architects don’t fully understand.

Layer U wasn’t built. It grew. In the spaces between walls, in the dead zones between surveillance nodes, in the frequency gaps between official broadcasts. A whisper network that became a shadow civilisation. Explorers are called Strands. Those who discover deeper signal anomalies are called Echoes, though what they’ve found, and what it means, depends on who you ask.

Officially, nothing exists outside MetaXity1. Irradiated wasteland. Toxic ocean. Death.

The Badlands say otherwise. Where the pyramid extends over the sea, its underside shelters the water below. Marine life survives there, shielded from the Mantle’s toxicity. Fishing still happens. Protein still comes from the ocean. Someone is eating it.

Where the structure meets land, the old rice bowl regions of Southeast Asia persist in perpetual twilight. The pyramid’s underside glows: a dark, unnatural UV light pumped downward through the base plates. Not sunlight. Not starlight. Something else. Enough to sustain growth. Enough to see by, barely. GM crops engineered for low-light subsistence. GM creatures roaming through jungles that shouldn’t exist under an artificial sky.

Not everyone who was “relocated” stayed inside. Some of the displaced, the ones who saw through the Founders’ promises, or who were simply never let in, came back. They shelter in the Badlands, living in the UV twilight, building communities the pyramid doesn’t acknowledge and SOVcorp pretends don’t exist. Scavengers, independent communities, resistance outposts surviving on salvaged technology and sheer stubbornness.

Most citizens don’t believe the Badlands exist. But Layer U relay stations pick up transmissions from outside. Voices. Coordinates. Proof, or at least something that sounds like proof, that the pyramid isn’t all there is.

The surface isn’t dead. It’s just not supposed to be alive.

A contested phenomenon. Spoken about only in encrypted channels, dismissed as paranoia even among Strands. Some explorers report experiences that shouldn’t be possible. Missions that predict events before they happen. Encounters with entities that know things they shouldn’t. Recurring patterns across unconnected players that feel less like coincidence and more like design. Layer U theorists call it Simulation Bleeding. Most dismiss it. But the reports keep coming. And no one has a better explanation.

The technology layer that underpins both SOVcorp’s media machine and the resistance’s most powerful tool. SOVcorp built LARP for one-way media delivery: what citizens know as Proper Gander broadcasts. Sanitised news. Approved entertainment. Corporate messaging designed to feel like connection.

The resistance discovered that the same protocol could be hijacked. Two-way signal jacks that turn passive broadcasts into active channels. Some Strands claim the protocol can do more than carry messages, but those claims remain unverified.

When you become a Blank, you’re not “starting a game.” You’re initialising a LARP.
