About two weeks after Tirek's defeat, Twilight Sparkle, Equestria's newest princess, finds an earth pony stallion at her new castle's doorstep.

Out of worry, she takes the stallion in. He comes to the next day, but he has no recollection of who he is, where he is, or how he got in Ponyville. The only thing he can remember is that he's looking for somepony. But... Who... and why?

After his arrival, dark things begin appearing all over Ponyville. Ponies start disappearing, and something dark is on the horizon. Other towns seem to have become silent, and Ponyville is in the center of it all.

Now the main story with four prequels that are totally unnecessary to read in The Forgottenverse. (The name is lame. I know.)
