Overion was a small planet full of Rajrans. The Great Hyperspace War, however, exhausted their resources, along with many lives. The Mandalorian Wars did little good as well. With barely a few hundred, the Rajrans were on the verge of extinction. Luckily, however, Rajrans rarely give birth to as little as even two children. The population flourished and the planet was restored.
Overion had a natural Force aura to it. All born on its surface had Force abilities, some manifesting as quick learners, incredible strength, or even the ability to control the elements. Many varied powers were possible.
