When I first created it, I developed the planet itself, but not the primary species. Credit goes to Noel for fleshing the cooreinians out as a people.
Coorei, as mentioned, is a swamp planet, meaning that most of the surface is covered in a thick mire. Massive trees (think redwood forest style) grow out of the marsh everywhere. The surface of the planet is home to hundreds of different extremely dangerous creatures. As such, the sentient species took to living in the trees.
The cooreinians are a race of bipedal lizard-like people. Exotic and powerful, they are by no means helpless - a testament to just how dangerous the creatures living below are. As a result of literally living above a swamp, their hair (yes, they have hair) is most commonly found in dreadlocks. Their immune systems are also very well developed from living on a very unsanitary planet. Though this is good for them, it isn't so good for non-indigenous species, as the cooreinians tend to be walking cesspools of bacteria and disease. Despite their somewhat barbaric appearance, the cooreinians have thrived as well as any other species and have even developed their technology to allow space travel.
During the great war, Coorei was a strong focus for the Alon, and Coorei has been forever scared from the battles that took place there. Some of the most violent and tragic moments of the war took place there where many lost their lives; Alon, Gifted and innocent alike.
In 109's time, the cooreinian people still fear both the Alon as well as gifted for fear that those terrible conflicts would occur again. So when Flynn was revealed to be gifted, his parents took extreme care to hide him. Eventually, Flynn's father heard about a safe haven for gifted: a floating island by the name of Lud. Soon after hearing of the safety the island seemed to give, Flynn and his father left Coorei to start a new life in the beautiful and wondrous city of Lud.
Flynn is Joe Bags' character. He's a teenage Cooreinian who can mutate into a giant beetle-like creature at will, thus making him the tank character of 109. It's also worth noting that Cooreinians have three eyes (which you can't see in the picture).
