A fan sequel to the MLP movie, inspired in part by the film's original premise.

A month after Twilight and company's trip beyond Equestria's borders, a new threat arrives to take advantage of the aftermath. But things aren't simple this time, and Twilight finds herself arguing with Celestia over how to deal with this new enemy.

The Mane 6 and friends will have to venture deep beneath Equestria and travel through a strange, alien forest to save the balance of magic. But can Twilight and her friends also save bonds that have been broken seemingly beyond repair?
