The nightmare six

A week prior to Rise of the Nightmare Mane Six, the Autobots and the Mane Six had been disturbed by a particular nightmare. The group figured a sleepover at the Castle of Friendship would help them figure out what was going on, needless to say, this backfired horribly and the Mane Six were kidnapped and carried off to the moon by the Nightmare Forces, where they are dubbed their new queens. They resisted at first, not wanting to hurt their friends or destroy their home, but they eventually relented due to the creatures exposing their fears once again and making them think they'll be forgotten. In their weakened state, the Mane Six get possessed and transformed into the Nightmare Mane Six and what will you do in the story will you save them or die?
