The Truant Project

The Executives say, that there was a time before the countries of Illithica and Lymphal. A time where humans warred with eachother, when they fought over resources, weapons, land. A time where some children went home, wondering whether their mother or father or sister or brother would come home alive by Christmas.
Despite all the horrid things of the past, the Executives also told us that the countries were also allies, aiding eachother in battle, or in times of hardship.
But they deny all claims of this.

Welcome to post-apocalypse Earth. There are only two known nations, Lymphal and Allithica. The previous inhabitants of this world wiped themselves out because of their nuclear weaponry and radiation, which eventually killed off the majority of the population. Sometimes, that's what Axel thought they wanted. The food is plentiful, but the population remains at the same, stable rate: 2,086,759,431 and decreasing.
The truth is, after almost half a century, a lot of the earth has been contaminated by various radioactive compounds, and that means land that you can live on without slowly disentigrating is kind of hard to come by. Almost half of the world is an unstable environment, including the area south of Allithica, which rests on what was once the country of Northern America's debris, and the region surrounding Lymphal, which is just on the border of Europe's ashes.
Lymphal and Allithica are not allies, but nor are they enemies. But they are competing for control of the remainder of Earth. And the population is competing for their very survival.
Did I forget to mention the Truant Project, a hazardous competition in which the adversaries are groomed for their televised deaths?

The Truant Project. It's main purpose is to keep the population under control, to keep the public entertained. But behind it is an even more sadistic twist.
Welcome to the remains of Earth, where the population remains just above two billion. Most of that two billion are adults. The
