This story is a sequel to My Little Pony, Friendship is Magic: Heart of Friendship
A collection of mostly episodic stories taking place after the completion of the Mane 6's latest mission and the humans' great migration from the Heart of the World. Both peoples can have very different values and outlooks, but life would be no fun at all if everypony, everycreature, and everyone were exactly the same, right? Old enemies might become new friends as new enemies make trouble that only multi-species teamwork can thwart.
