A young filly enters Ponyville, nearly dead from exhaustion.
She has wings and a horn. Her mane ebbs and flows.
The Crusaders decide that she should be their little secret.
But who is this mysterious litttle pony, and why can the Crusaders not bring themselves to reveal her?

Meanwhile, in Canterlot, Celestia and Luna detect something is amiss, and launch an investigation.
