Months ago, a tear opened up in the sky. Only through the intervention of the princess was the tear closed, but not before something came through. Something from another reality. Something not of Equus' soil.

They called themselves humans.

Only a handful were found, barely the amount of a few hundred. In the beginning, the humans were scared and afraid, but slowly they adjusted. Months passed and things finally appeared to return to a sense of normalcy.

Then it happened.

An incident that rocked Equestria to its core, shook its foundations more then the changeling attack on Canterlot.

It was dubbed,simply, the Human Event.
