Cearuleum is a warm D-Class planet, that was discovered on accident. It orbits a blue-supergiant. In a private laboratory somewhere on the outskirts of the Milky Way, human scientists were researching wormholes and space-time manipulation. They made a Dyson Sphere around a star, and harnessed it's energy to power the wormhole. It then transported them to a distant galaxy, but closed behind them. They were stranded there. They came out near Cearuleum, and landed there and set up a colony. The group formed their own country, a small group of scientists living near the poles of the planet. They populated the planet, and made their own civilization. The Caeru Republic. They started to visit and colonize the other 10 planets in the system, and now have a population of 10 billion.
