[@Aeonumbra] Hi there m8! I play league a lot. You on any Eune servers? Ranked rank?

Anyway, ahem, I would like to throw in my theory of what happened.
The government was testing a new chemical, in case that it came in contact with humans, it behaves as a mutagen which regressed the DNA of someone to an earlier age, to an age of feral beginnings where man kind fought in their primitive form. This substance was tested on many areas throughout the world and many people fell victim as a result. 

Many researchers have argued that light exists in fact outside of time, and that what we see is simply the manner in which the interactions of light with matter keep dragging light into spacetime, and in the process, expanding one photon into what appears like many.

Now what this chemical did, instead of interacting with the photon like any normal matter would, it interacts with the past state of the photon. It interacts in such a way that it draws the photon in our space from a past time. With machineries that read the information that is stored inside the photon, they are able to project the state of the weather that happened int he past to the present.

By placing large satellite dishes on the space surrounding earth, they converted the light which falls upon earth, to the light which fell* upon it in the past. Light and photons which carried that information which in turn was projected by the use of the chemical which was spread over air. 

They thought they had everything planned out but even the smallest current of wind which is formed by a butterfly has dramatic chaning effects over everything that happens on earth. And for such an intrusion to the spacetime continuum, the changes were beyond anyone's belief. All hell broke lose and everything became chaotic but the universe has a way of fixing itself and with time everything came into order again.

And there we are after everything has settled down.
