The end of equestria

This story journeys all the way across equestria, but it starts in a creepy shop in a clishè dark ally way. A small gray mare with no cutie mark walked into the shop. She had a dirty blond mane, with a gray horn barely peeking out of it. She was obviously fully grown, but possessed no cutie mark.

"I would like to deposit a book." The mare said. "Its about dark magic."

"Ok." The shopkeeper mumbled. "Heres your bits."

She turned and left the shop, her tail frisking behind her.

"Wait," the shopkeeper shouted coming to his senses. "Whats your name?"

"Forsythia." She said, right before she walked out the door, leaving nothing but a book of questions, and a gray hair.
