Let's start at the top, shall we?
Our story takes place on an Earth-like planet named Bellum. It is the oldest inhabited planet in the known universe, according to Bellum scientists at least. Technology here has advanced to the point of gravity manipulation, giving rise to flying cars and much more. Also, the organic lifeforms here have evolved to the point that they can internally harness the energies of their sun, their planet's core, and the stars at night; this is more commonly referred to as "magic".
The dominating society of Bellum is arguably the humans. There are three major continents on the planet, each one controlled by a different human society.
The first continent is controlled by the Sutisu people, a proud and mighty group that also claim to be the most technologically advanced.
The second continent, which is attached to the first, is controlled by the Riotifu people. The Riotifu are known for being rough around the edges and quite unpredictable, the opposite of their Sutisu neighbors.
The Riotifu and Sutisu people are rivals in every way, and are constantly at war with each other.
Far to the south, you will find the third continent. The Mutrenu people are a peaceful society, as far as humans go. They avoid direct physical conflict, but they are savvy business people. Should they ever have to go to war, they would surely have a tactical advantage.
