Regina has given up on her life in Storybrooke following the death of her mother, what happens when she tries to leave and winds up in a place that is decidedly not Earth?

Belle Blue-Eyes was a beautiful mare who was banished into the enchanted mirror by the Evil Queen. Rumplestiltskin the Gold Spinner was an ordinary stallion who was cursed. Two lonely hearts, one brave, one cowardly, will collide one day. Will Rumplestiltskin ever see beauty in his own reflection? This is my story. I am Belle Blue-Eyes, the Mare in the Mirror.

The Evil Queen cast her curse and sent everyone from the Enchanted Forest to a new realm. Unfortunately, she messed up somewhere and the curse sent everyone to Equestria instead of Earth. The curse is now broken and Rumpelstiltskin/Mr. Goldhoof is on a quest to bring his magic to the way it used to be. Based on this FB page: Mr. Goldhoof (FiM)
