Who are we?
We are an organization originating from year 2109. Our goal is to restore the Earth to it's pure state through a global effort. See the The Collapse for more information.
Through the use of highly advanced technology that us humans have invented, we will achieve this goal.
When we say "highly advanced technology", we mean the current technology within your timeline, only far more better, along with other newer inventions that have proven to be beneficial to us.
However, some inventions of humanity have been lost from us and we are unable to retrieve such devices. Only a few devices, particularly digital devices are needed for us to complete our mission.
What happened to the Earth?
To put it short, we, as a human race, failed. See the The Collapse for more information.
