It was a small planet in some unimportant galaxy. It had resources, not too many, but enough. A decently advanced civilization and a few nations that for the most part existed in harmony. The landscape was quiet amazing and so what the vegetation and animal life on the planet. The entire scenario was like a slightly twisted and more advanced version of Earth. The cities were grand, hulking mountains of white steel that stood out in the lush green of the plains they found themselves in. The completely automatic defense systems were hardly used and economy was doing well. For most of the countries and cities the past few centuries have been nothing but a blessing and a golden age. The people were especially thankful, considering that the history prior to that was filled with war, death and struggle for survival. Nowadays, other than one or two religious or political disputes there was little to no conflict. None-natural death rates were at a minimum, the average life span had been increased by nearly 30% and crime rates were at a new record low. An average family had two kids and both parents were working. The educational system had gone through some reforms and the new generation was just getting used to it. New technological discoveries had improved productivity, offered alternative energy sources and opened up new workplaces. While the gap between the rich and the poor was still present, it was getting smaller with each passing day and because of the economical independence of the nations discrimination and tensions started disappearing too. Though a number of deadly plagues was still present in many sub-urban places and even some of the major cities, thanks to the stabilization of the general affairs, resources could be focused on developing a cure and scientists were confident that they were on the right path. They also had the chance to amass impressive amounts of knowledge, storing them away to be used in the close future for further progress. Like planting seeds so that one can harvest the fruits later.
It was a world experiencing a steady and secure rise with a bright future to look forward to. Sure it wasn't a perfect paradise and probably didn't even meet Earth's standards of an Utopia, but it was still a damn fine place to live.
Then all changed.
For the first time in it's history the planet was faced with invaders from outer space. An Empire using it's extraordinary military power was aggressively spreading through the galaxy, taking one planet after another at a very rapid pace. The planet never experience such large scale warfare before and had to oppose a threat to which it couldn't adapt. The main army was quickly broken up and smaller resistance groups were formed. Though they did manage to slow down the rate at which the planet was being overtaken, they did know that they were just dragging out an event they couldn't stop. With the time of war passing the hate towards the invading Empire grew larger and larger. At it's peak preserving the planet, the nations, cities and even the people was no longer important, deal a blow to the enemy took priority over all. And as such the last weapon of defense was unleashed. Fission Bombs, like Earth's nuclear warheads, but those were dwarfed in comparison by what these weapons could do. In a matter of a single week the entire planet had been turned into a dull desert wasteland. A good part of the population was dead and the worst of all, the enemy had no been stopped.
In regret the scientists made one last effort to correct their mistakes and at least give one part of the world they had taken away back to the people. The collective consciousnesses of the planet's surviving population was uploaded into cyberspace, abandoning their physical bodies and the harsh world they themselves had created. What they found was a lose replica of their former lives, but they adapted. It did not last too long as the Empire followed them even there. They were not after the resources of the planet, but the knowledge of the civilization and the potential it held.
A new war broke out. But perhaps this time they would have a chance.
Some Years Later
Inside a science lab on a small research complex a young platinum haired girl was moving through the halls. With here was a squad of five armed men. Here eyes were as steely as the floor she walked upon. This was her day, a day to make yet another small change that would shift the scales of war and end the conflict that had torn apart her planet many years ago.
She had determination flickering in her eyes and hatred burning in her heart.
