Digimon: Eclipse
Prologue: As The Sun Bled
The small log cabin in the middle of the desert was easily the largest building for miles on end. It was also probably the safest. Stepping out into the barren wasteland, the desert and the lack of water was the second biggest issue.
The first was, of course, the hordes of snarling, blood-hungry, crazed monsters. Digital monsters, that is.
In the beginning, the world was at peace. Split into five continents; very simply they were 'North', 'South', 'East', 'West', and 'Central'. For as long as anyone could remember, the world had been ruled by the constantly immobile Yggdrasil. A massive AI core implemented inside a massive, supposedly impenetrably, Chrome Digizoid shell. Without Yggdrasil, it was rumoured that the sun would fall from the sky and obliterate Central, the fragments flying so far that they decimated the other four continents. There would probably just be a nuclear winter, and all growth would stop, due to the link to the Real World being cut off. That link was located in North. The Bifrost Bridge. The only link between the two worlds, data constantly being received and sent. Very few humans had complete and total access to the Digital World, and, they knew that if it was compromised, all hell would break loose.
Everything would break down and they'd be forced into a state of complete collapse. Anarchy would reign supreme in the streets. People would die daily. Before long, the Real World would be in just as bad a state as the Digital World.
Just as powerful as Yggdrasil's defences were, it had no form to move about with. So it created itself thirteen knights. The famed, exalted Royal Knights. Whilst each one was as brave and courageous as possible, before long, friction came from their imperfect attributes. Leading one party was Magnamon; a complete and total believer and supporter of his master. For a while, all the knights were like this; after some time, Gallantmon began to question his master. 'Why?' he asked. 'Why did we have to give up everything to serve him?'
He split away, and along with four others, lead a devastating attack on Yggdrasil. Magnamon and the remainding knights managed to fight the rebellion off, but not before Yggdrasil's casing was penetrated. The rebels fled, and Magnamon's party moved towards Yggdrasil, only to discover that the core had started to have its judgment clouded, and question its orders. Yggdrasil was no longer a machine; it was a tyrant. The ruling AI thought only of tyranny, not taking care to heed the wishes of the inhabitants of the digital realm. It cast out the remaining knights, who in turn split into groups; Magnamon's group, still true to Yggdrasil, but working from the outside, and the Pilgrim Knights, lead by Omnimon, who instead chose to travel and fight on their own, aiming to become stronger so they could one day liberate the corrupted core.
That was twenty human years ago. Since then, Yggdrasil has built himself an army, and the three groups of knights constantly at war. The corrupt AI has already released over sixty viruses into the Digital World, only the most strong-willed of Digimon being able to protect themselves against them. The most significant of these is a virus that triggers an unstoppable rage. Scans from the Pilgrim Knights show over 80% of Digimon Champion level and below have been infected.
This is a turning point in history.
This is Eclipse.
