The earth is no longer suitable for life. People settled many new planets that were united into a single state "Paradise". This state is ruled by the Eden system, an artificial intelligence, a God created by humans to end wars.
The over 400 years of peace are about to come to an end. Over time, numerous people dissatisfied with Eden's policies emerged; they left the system and created new civilizations, earning the nickname 'Fallen Angels'.
For Eden to exist, continuous expansion is necessary to acquire a greater amount of resources, to sustain and upgrade all systems.
In such a wonderful world, the story of our heroes will begin.
