Dipper Pines has done it...he's reunited with his friends. Torn apart by the whims of fate and treachery, he's finally returned to them...and he's brought the whole dang town of Gravity Falls with him! A happy ending right? Weeeelll...not so much. Turns out you can't throw a bunch of people from a dark crapshack world and throw them in the middle of a land of hope and happiness without consequence...who knew? It doesn't hurt that the Mane Six's new friends are keeping secrets from them...secrets that'll shake Equestria to the core and end the Status Quo forever...Oh, did I mention that not everyone back on earth is happy with the current situation? Like the three most evil gangs in Earth history?
