But you're overreading as well. The Void can see them, nothing more. The Light can also grant visions of the future. Neither has the ability to manipulate time, at least, not any more than anybody else does.
There's a reason why the Void wanted to change it and from our perspective it might appear evil not until we know the motivation behind their action if it is indeed justifiable. Who know the light might have its own dark side or shadows casting else where that is being complete hidden beyond our sight.
