The days in Equestria were nice, peaceful, and tranquil. That all changed when a big glass box came hurtling from the sky and crash-landed on her farm in Ponyville. Within the foreign object was a human,the first human to set foot on Equesrtian soil. Unfortunately, this human has no memories of his past. The only thing he does know is his name.

"Zero. My name is Zero."

With only a number as a name, the amnesiac young man is taken in by the residence and taught the ways of their land. As he's learning about his new home, questions start to creep into his mind every waking moment and every dream at night;

Who am I? Why am I here? Where do I belong?

But when an evil, the likes of which Equestria have never seen before, threatens to tear his new world apart, Zero must put aside his search of self and answer one new question;

What would you do to save a world you don't belong in?
