🌌 The Lost Civilization
No surviving chart records their borders. No history names their rulers. No living species can confidently claim to have met them.
They are known only through what they left behind.
Long before Captain Nathaniel Flint discovered the world that would become known as Treasure Planet, an unknown civilization possessed knowledge far beyond anything understood by the Terran Empire, the Procyons, or perhaps any modern people of Known Space.
Treasure Planet itself was their greatest known monument—or perhaps merely the only one yet discovered.
⚙️ Impossible Technology
Treasure Planet was not truly a natural world. Beneath its mountains, forests, and oceans existed an immense planet-sized machine, filled with mechanisms that continued operating long after their creators vanished.
Most famous was its extraordinary portal technology.
Using a relatively small control device, gateways could be opened between Treasure Planet and locations separated by enormous distances. Entire ships could pass through these portals as easily as sailing through a doorway.
Even modern scholars struggle to explain the energy required for such a feat.
And yet the builders apparently considered the technology reliable enough to construct on a planetary scale.
🌀 The Great Mechanisms
Explorers who study accounts of Treasure Planet point toward another unsettling detail: the world contained mechanisms of astonishing size and complexity, yet remarkably little evidence explaining their original purpose.
Was Treasure Planet a transportation hub?
A fortress?
An observatory?
A machine for manipulating the Etherium itself?
Nobody knows.
Some scholars even question whether the world discovered by Flint was originally called Treasure Planet at all. Flint may simply have found an abandoned machine and transformed its enormous interior chambers into his legendary vault.
If so, the treasure was never the planet's true purpose.
🌠 Other Relics
Sailors occasionally return from distant regions carrying strange artifacts supposedly belonging to the same civilization.
Most are frauds.
A few are harder to dismiss.
Fragments of unknown metal that cannot be melted. Devices that react to nearby stars. Mechanical components containing no recognizable gears or power source. Ancient structures whose geometry seems to change depending upon where the observer stands.
No connection to Treasure Planet has ever been conclusively proven.
Still, the rumors persist.
Some treasure hunters believe other artificial worlds exist somewhere beyond Known Space.
📜 What Happened to Them?
That is the greatest mystery.
A civilization capable of constructing Treasure Planet should have left an enormous mark upon the universe.
Instead, there is silence.
No confirmed cities.
No fleets.
No descendants.
No explanation for their disappearance.
Perhaps they destroyed themselves.
Perhaps something destroyed them.
Perhaps they abandoned Known Space entirely.
Or perhaps, as old Etherium sailors sometimes whisper, they never disappeared at all.
🔥 The Oldest Rumor
There is one story particularly popular among treasure hunters.
It claims Captain Flint eventually realized Treasure Planet was only one piece of something much larger.
According to the tale, Flint's obsession with treasure gradually became an obsession with the civilization that created his secret world. He supposedly used its portal mechanism to search distant corners of the universe for other remnants of the builders.
Whether any of this is true died with Flint.
Treasure Planet itself is gone.
Its creators remain unnamed.
Their history remains unknown.
And somewhere beyond the furthest charts, there may still be machines quietly operating exactly as their builders intended.
Treasure Planet proved they existed.
Everything else is rumor.
