The Unnamed Operator finds himself someplace he isn't supposed to be; a place that did not exist in his universe. Crashing into a winged pony, he finds himself learning about a place that doesn't have the threats to life that his home universe has known for many thousands of years.

Upon discovering this knowledge, he must eliminate all of the threats, some obvious but others hidden, otherwise Equestria will be destroyed by an enemy that it cannot combat, one that is immune to magic by nature of their design.

But he is not alone...
