The Uncharted Land

The Uncharted Land is an in-progress My Little Pony Friendship Is Magic fanfiction written by Blue Ridge Mountain Man.

After a Troll attack leaves Scootaloo orphaned, she is adopted by her hero and role model, Rainbow Dash. Rainbow then helps Scootaloo recover from the tragedy and get back on her hooves, and the pair grows closer than ever. In addition, Ponyville gets a new resident in famed disk jockey Vinyl Scratch, and she becomes fast friends with Rainbow Dash and Scootaloo, as well as the rest of the mane 6.

But what about the Troll that killed Scootaloo's parents? And does the attack have anything to do with the great Troll/Equestrian war that took place hundreds of years ago? And what is notorious Manehattan mobster Clyde Persano up to in Ponyville? Could he have anything to do with it?

A series of events unfolds that leads to Rainbow Dash, Scootaloo, Applejack, and Vinyl Scratch embarking on a heroic journey into the Troll homeland... the forbidden region north of Equestria known only to outsiders as The Uncharted Land.

The story underwent a major revision early on that resulted in it basically being restarted from scratch, with improved plot development, writing and characterization. It is currently in progress, with chapter V being the most recent addition, so stay tuned.

 * Orphans Ordeal: Most of the beginning involves Scootaloo dealing with the deaths of her parents, and Rainbow Dash adopting her and helping her grieve and get back on her feet.

 * Roaring Rampage of Revenge: Something happened in Whiteclaw's past that filled him with a desire to commit genocide against the Equestrians.
