The Universe Particles or UPs, an unknown particle that appeared on Earth and infected all the living organisms, humans who got infected by this particle started to get sick and eventually they died.

The leaders of that time employed thousands of scientists to search for the cure but to no avail. Five years later the cure still hadn't been found but the number of deaths were increasing with each day, in these five years one billion of lives had been lost.

Fearing the worst the Leaders of all countries came together and decided to build Twelve Stations underground where humans could seek shelter. Seven years later, two billions and half lives had been lost but all the stations were safely completed, but there was a problem…it couldn't fit everyone…

The leaders with this problem in hands could do nothing but choose the fittest and the best of the best in their field of work: farmers, doctors, researchers, soldiers, teachers, etc…
