Knights of Sidonia: The series ends with the crew of the Sidonia establishing a colony on the seventh planet of the Lem star system, before the Sidonia launches once again in search of more worlds to settle.This is an odd mix as the colony's existence is known but Jurai has left it alone aside from maintaining contact with a few governments. Earth in Tenchi Muyo! is a colony of Jurai, officially known as Colony World 0315.Rakuin No Monshou is set on a colony where most of the technology brought from Earth either degraded over time or was expended while subjugating the natives.Since the Protoculture are long dead, though, their original plans seem to be largely moot. Accounts vary as to why Earth was forgotten and why humanity (a genetically-engineered offshoot of the Protoculture) was left there, some saying it was a long-term colonization plan and others saying humanity was an experiment, though subsequent Macross series have revealed that the Protoculture left a wide variety of offshoot species across the entire Milky Way. Super Dimension Fortress Macross reveals that Earth itself is a lost colony of the Protoculture.Unfortunately, the Guild who oversees the system got lazy, causing the climate to become unbalanced, and in turn sparking intercontinental warfare. Last Exile is set on Prester, which is actually an artificial planet built to be a perfect colony for humans.It's unclear whether Simoun is set on a Lost Colony populated by genetically altered humans, or whether they're humanoid aliens on their homeworld After the End.
The tiny percentage that survived were forced to cannibalize their ships to create viable habitats, and by story's present date, over a hundred years later, very few signs of the original ships or their technological advancements remain.
They originally planned to pass over Gunsmoke, as it was only barely habitable, but unfortunately one of the sapient genetically-engineered beings they were using as a power source chose that time to strike against humanity, causing the ships to crash on the planet's surface. Trigun: Project Seeds was a fleet of Generation Ships looking for a new planet after Earth got used up.
Earl in My-Otome, while otherwise fitting this trope, at least remembers that the people and the Lost Technology came from Earth.Of course, the theory of panspermia, that the first bacteria were dropped on Earth from space, still enables a scientifically plausible "Lost Colony" in a far more general sense. And sometimes the old technology and genuine magic are used side by side.Īnd of course, it's always popular to reveal that Earth was really a lost colony and that Humanity Came From Space, though genetic evidence that humans and other Earth organisms are biologically related, all the way back to the first bacteria, has made this increasingly hard to sustain. Sometimes there is genuine supernatural magic happening, or something that can pass for it, and all advanced technology has been lost. Oftentimes whatever remains of the old technology will be mistaken for magic by the colonists' descendants. Either way, not only do their descendants' politics, economics and culture regress to match their pre-Industrial Revolution technology level, they also forget that their ancestors ever came from another planet, making the story at first glance seem to be set in a pure fantasy world.
