Shining Armor doesn't know much about his origin. Where he came from, who his birth parents were, how he ended up being found on the edge of the frozen north; heck, he didn't even know the name of his species until he was in the Guard Cadets. Personally, he didn't care much to find out more: He loved his parents, his sister Twilight, and especially Cadence.
Now, ripped away from his family and the support of his nation, he's gonna have to learn... Quickly.
