Chapter One

This is a Gravity Falls fanfic. It starts when Dipper and Mabel are 'born'. The truth is Mabel and Dipper aren't twins. They aren't even siblings. Dipper is a demon. However with a little possession and manipulation Bill is able to convince the Pines family that Dipper is Mabel's twin brother. Why? Because Bill just wanted to protect his brother from the war in his dimension. Everything goes great. But what happens when Dipper finds out he isn't as human as he thought? And Bill comes to claim his brother? I do not own Gravity Falls. Alex Hirsch does. I also do not own the art on the cover!
