World History

Each continent tells time differently. According to the Northern continent, it's the year 961. For the Southern continent it's year X. For others, it ranges from 2050 to 7. Generally, the planet is seven billion years old, with sentient beings populating it around 70 million years ago. Originally it had only one group of humanoid people, who slowly evolved and changed into several different distinct groups. There's question to how closely related all the species are, since some can interbreed quite easily, while some struggle.

The Wars
The world lived in relative peace, until people started learning how to travel beyond their countries. Humans were the first to spread themselves out across the world, all the way from one pole to another. Annoyed, other species attempted to push them out, but the humans claimed they were the dominant species, and started exterminating anyone who wasn't obviously human.

The first to go were the Madrians, a mainly pacifist species that were primitive when it came to technology, but advanced when it came to spirituality. They were killed off quickly, their extinction frightening other species into gathering arms and going after the humans in return. After thirty years and millions of lives lost, the UN was formed out of desperation to keep more genocide from happening. The United Nations was formed of one or more leaders from each country, and set up in an area where neutrality must be inforced. Agreements were made, and the war ended.

Thousands of years later, and the current Airdan king has built a city that can fly. His country is failing when it comes to space and food, so he moves much of the Airdan population onto the floating city and directs it South, to hover over human land. Of course there were protests over the stolen land, though it was largly unused. All trade was cut off to Airdan populations, and fights broke out. Soon enough there were full on assults on the city by humans and their allies, demanding the city be moved back north or be destroyed. The war is still going on now.
