The planet of Eos was for the most part a sprawling forest. The densest jungles in the quadrant. No one really knows why, but at some point, centuries ago, humans had begun to settle along the coasts. They came from space, yet at some point were forgotten by their interstellar comrades. The people of Eos’ starships had first fallen from use, and then disrepair.
They had managed to establish a bountiful and sustainable level of agriculture. They were simple people, a culture worn out from generations of being trapped in space. Their folk tales kept the image and woes alive of what it was like to travel in space. Almost total darkness, the beauty of the stars slowly fading in appeal. Even their largest starships began to seem like a sort of prison within a few years.
As much as the engineers did to combat this, adding flora and open spaces, it was like being trapped in a small village. Many lives passed aboard those ships. They were a sacrifice for a greater cause. Countless heads knowing nothing but the inside of a tin can. The humans knew that once they arrived at their destination it would be the end of their space faring years. The real reasons they sought out this planet and endured space travel have all been lost, but it was known that they wouldn’t be leaving.
You could speculate that these space pioneers had gone through this in order to escape humanity at large. It carried too much baggage from its past. Unsustainable economic systems, a culture that drove many people mad, it was something that had lost it’s sense of being natural.
Legends of the Earth tell that humanity was always this way, but these travellers thought they could do better. They could create a lifestyle that was in harmony with a world, a place where people would cherish each other’s differences. To respect all living things, especially sentients, and work together.
It makes sense now, out of all the planets that could bare human life, Eos was the only one that might detract any more colonists. The leg work involved made it totally unappealing. Luckily for the original settlers, they made quick work out of establishing a small scale society. They cleared out just enough of the forest for agriculture to keep them sustained.
They still carried with them a great deal of science and technology. Their starships were the perfect seed for a civilization. They could maintain their level of understanding. The ecosphere of the ship still provided much of what they needed to survive. It was the nano tech that made it possible. Their ability to rearrange atoms as the saw fit.
