The Crystal Empire has made its mysterious return back to the land of Equestria. While the crystal ponies attempt to recover from their long slumber, something more sinister also came back. When the mad tyrant attempted to siege the city, one pony held him at bay. The only distinguishing features of this stallion were his blue hoodie and his large smile.

Nearly all the magic in Equestria has been absorbed by Tirek. With his newly acquired power, the demon-centaur is unleashing destruction upon the land. His plans for conquest were just getting started. After Equestria, then Griffinstone, the Dragonlands, and the Changeling hive. All magic on this planet will be his to control.

But, there is hope. The Tree of Harmony gifted a crystalline chest. Only with six keys will it open. With Discord's friendship revelation, they received the final key. All they can do now is hope, hope that whatever is contained inside the chest is enough to stop Tirek.

Soon, they will see the coming of the invincible incarnation of power: the Lion's Sin of Pride, Lord Escanor.

Chapter 1 adapted from Tirek is Doomed.

Stranded in an unknown world and in a new body, Ben must try and start a new life while dealing with the crises that happen every week.

Once upon a time, in the magical land of Equestria, there were two regal sisters who ruled together and created harmony for all the land. To do this, the eldest used her unicorn powers to raise the sun at dawn; the younger brought out the moon to begin the night. Thus, the two sisters maintained balance for their kingdom and their subjects, all the different types of ponies.

One day, the sisters stumbled upon an orphaned colt on the outskirts of the Everfree Forest. Although he couldn't remember much of his past besides his name, the two sisters could see and feel the potential coming from him. In the end, Celestia adopted him as her son.
