Planet Illios is the home world native to the Jackyl species. It is a planet roughly about the size of Neptune, and home to many different environments and cultures. A lot of the plant and animal species found on Earth are present here, alongside many that are native only to Illios. Some places are slightly more advanced than our modern day Earth societies, while other places are more primal; where little to no technology exists at all. Places with such drastic differences are likely to never meet due to the planet's large size. Illios has two moons, and a planet about the size of Pluto which orbit it. Space exploration is still in the early stages to learn more about these places.
