At 3:37pm, a package at the Ponyville Post Office and General Delivery Service exploded. The explosion spread flame and heat. Fire licked at the envelopes, charred letters, burned papers, melted stamps, blackened books, invalidated forms, destroyed labels, and consumed packages. The flames devoured paper and attacked the more solid pencils, wooden desks, and mailboxes. The heat shattered windows and let in more air. The once-small fires engulfed the wooden structure, burning everything from ceiling to floor.

When the package exploded, no customers were in the store. Only one employee was there; all others were delivering mail and packages. The blast killed her instantly: a mail mare pegasus with a grey coat, a light yellow mane, and two eyes that had rarely focused on the same object.
