Timeclot

Are all events predetermined by technologies we've created, or by some unknown power? If reality is what occurs after you stop believing in it, what happens when a few unwholesome folks stumble upon portals in the space-time continuum to change it? Greedy, politically motivated people gum up the works, altering the tapestry of time. Who eliminates the clots that divert time's tributaries? The Time Bureau of Investigation was established in 2070 so people with altered DNA can repair the damage done, assuring the flow of history.
