In the year 2062, mana came to earth.  The introduction of this new type of energy brought the world to the brink of destruction.  Almost two thirds of the population couldn't cope and died from an illness that we now call mana bane.  After the vast majority of humans died, the flora and fauna began to change.  It was an initially slow process, but the longer these creatures were exposed to mana the more they began to change.  Plant life flourished and forests seemed to regrow over night.  Meanwhile, animals became stronger, faster, and smarter due to the increasing changes that the planet was experiencing.

     Humans fared far worse during this time.  Those that survived the initial arrival of mana would find themselves basically helpless when it came to surviving without the help of technology.  Mana had done much more than simply wipe out the vast majority of humans.  It had also destroyed basically all forms of communication and transport as well.  Nations fell overnight and chaos fell on the individuals that remained.

     It took several decades to regain a semblance of control.  Once humans began to organize again, the saving grace finally appeared.  No one knows why it happened when it did, but the best guess is that it just took that long for mana to concentrate enough to all it to become active.

     The system made its presence know in 2090.  The introduction of the system allowed the previously weak humans to gradually grow stronger, harness mana, and gain skills that would eventually lead to reconnecting with the rest of the world.

     In 2120, the new world government was created which marked the beginning of a new era for the human race.  To mark this, the calendar was up dated to reflect as year 1.  For a few more years, humans world spend their time regrouping, creating central cities, and doing search and rescue of all the people that wanted to be saved.  Unfortunately, this was only the beginning as much worse tragedies were still lurking in the dark.
