My Little Pony: Friendship Undying

The once peaceful land of Equestria is once again, in danger. An evil, sealed away long before the princess of sun or moon were born has arisen, and he is slowly gaining power. What the evil didn't realize was that he brought along with him the three souls of those that sealed him away. The spirits ran away and travelled, finally finding three creatures, all sharing many traits they had when alive. It was decided by the eldest spirit to take these three as new protecters, and send them to their home. But this caused the spirits to wither up, and finally pass on, completing their task alongside the prophecy. For the creatures, it is only the beginning of their long quest, a quest that shall test all that makes then who they are in their Friendship Undying.
