It is the future and time travel is real. But it is not the time travel where you step into a machine and step out in another place, instead it is the passing of consciousness and control from present to the past. Two factions understand the power and use of this new development and intend to use it to save the world from an unclear but definitely approaching disaster. The Authority seeks to create a world free from turmoil and strife by keeping things nice controlled and orderly. The Network wants to unhinge linear time enough to prevent this dark future, while maintaining mankind's freedom. What would you do if you had the power to change the past? How will the future react as you become an Agent of Change.
