Ponyville is a Magical universe where talking ponies, dragons and other creatures live. This is the home of the Main 6, Applejack, Rainbow Dash, Rarity, Fluttershy, Pinkie Pie, and Twilight Sparkle. And on one night, disaster would strike.

A mysterious Pony wearing a disguise, came in and stole the crown sitting beside Twilight, Twilight noticed, and gasps, "My crown! She's got my crown! Stop! Thief! She's stolen my crown!" The rest of the main 6 follows her, and chases after the pony. Twilight teleports in front of the pony, "Stop!" Twilight exclaims, however, the pony teleports behind her, now revealed from her cape, an orange unicorn with a fire red and yellow mane. But then, Twilight catches up as the orange pony's eyes widen, she then gets tackled to the ground as the nearby door opens, the crown clacks and clangs all over the room until it eventually goes towards a mirror, going straight through it as if it was a body of water.

"WHAT DID YOU DO WITH MY CROWN?" Twilight yells, "Sorry it had to be this way, princess..." The Unicorn replies as it teleports in front of the mirror and follows the crown into it. All of whom is left in the room gasps in utter shock, as Fluttershy asks "Who was that?".

Later on, the group, including the young dragon, Spike, are gathered in front of Princess Celestia, Cadance and Luna.
Celestia starts speaking, "Sunset Shimmer. A former student of mine. She began her studies with me not long before Twilight. But when she did not get what she wanted as quickly as she liked, she turned cruel and dishonest. I tried to help her, but she eventually decided to abandon her studies and pursue her own path. One that has sadly led to her stealing your crown."

Spike speaks up, "She replaced Twilight's with this one." He presents a fake decoy crown to her, which doesn't have the crystal imbedded in it, this is known as one of the "Elements of Harmony".

As Princess Celestia takes a look at the false crown, she exclaims "I suppose Sunset Shimmer thought you wouldn't notice right away that this was not yours. And by the time you did, it would be too late to go after your crown and Element of Harmony."

"But I don't understand," Twilight Says, "Where did she go? Where did she take the crown?" "You'll soon know more about this place than even I do", Princess Celestia Replies.

Princess Luna looks at the mirror, "This is no ordinary mirror. It is a gateway to another world. A gateway that opens once every thirty moons, it has always been kept in the throne room of Canterlot Castle. But when Princess Cadance took over the Crystal Empire, we sent it here for her to watch over".

Princess Celestia sighs, "I had always hoped that Sunset Shimmer would someday use it to return, to come back to Equestria seeking my guidance. Obviously, this is not what has happened."

Princess Celestia Proclaims "Twilight, you must use the mirror to go into this other world and retrieve your crown. Without it, the other Elements of Harmony have no power and Equestria is left without one of its most important means of defense". Princess Luna agrees, "Your crown does not belong in the place Sunset Shimmer now calls home. And in her possession, your Element of Harmony will no doubt be used to bring harm to the inhabitants of this other realm. They will not have the power to defend themselves."

The 3 Members of royalty are interrupted by the mirror opening. "What's happening? Is she coming back?" Twilight asks, but before anyone can answer, a human boy spills out of the mirror.
