Wow, thanks for the opportunity, I really enjoyed your main series will check out the side one too! Here's mine
The story takes place in a fictional world where every twenty years a global war happens. Three major countries, Nilica, Sundestin and Norzeim, fight for the sky. Because if you control the sky, you can control the whole world, as proved five centuries ago by the inventor of the plane, Sam, the Sky Master. Wars are destructive and cause a lot of pain and grief, people build walls in the sky, own airspace above other countries, terrorize and kill each other. Our heroes as well as our villains want to stop these endless wars but in very different ways.
