Before

The world wasn't so much of a great place before the 2150's. It was full of wars, terrorist attacks, starvation, incurable viruses and diseases, racism, inequality, the list goes on and on. It wasn't until World War III, ending in a nuclear bomb that nearly destroyed the Earth, that everyone decided it was time for a change.

Well, almost everyone.

  When the population of Europe and Asia was wiped out in the explosion, North and South America, Africa, Australia, and Antarctica were the only continents left standing. The leaders of every country on Earth all joined together, established a new government, and called themselves the United Continents of Earth. From then on, the dream of world peace had actually come true. Since the population of the continents were united, they found cures for diseases, cancer, and viruses. Long gone were wars, inequality, starvation, and famine.

  However, a certain group of people didn't agree with the government. They protested that the UCE was hiding something from the general population. Unfortunately, nobody listened to these protestors. Most of them were killed off, while the remaining 100 were put in a high-security prison on the moon.

  Who were these people? They were the Corruptors.

(P.S. Days on the Lunar prison go by days on Earth, because days on the moon are just way too long.)
