A week had passed since Twilight's Birthday in 1985. Twilight had went out of her library one morning. The streets were unusual busy. A big crowd had arrived in front of a house in Ponyville. Scientists, vets, doctors and many others had surrounded a house. Carts surrounded the busy house that morning. Twilight met with her five friends and Spike.

"You can't get into that house, as a family has a Changeling on visit." a Canterlot guard told Twilight.

"Changelings had been told to make a threat against Canterlot up against the upcoming Royal Wedding this weekend." Doctor Hooves told Twilight.

"That's the first time in years I heard ponies talk about Changelings, as they only appears in fairytale books." Twilight told her friends.

A Changeling from the Applewood forest were arrived in Ponyville, and three fillies kept the Changelings as a secret. Flim and Flam had arrived in Ponyville with their technology to help the ponies and the Changeling in the house too.

"That can't be the Changeling queen from the books I read about." Twilight said to her friends.

"From what I know they come to the Wedding to feast on love." Nurse Redheart said to Twilight.

In the meanwhile had a large and clear shiny bubble been placed over Canterlot to protect from the Changeling threat. That balloon like thing who had been build up should had been strong enough to keep the Changelings out under the Royal Wedding.
