Welcome to Reverse Falls

You, a thirteen year old girl, leave your friends and family behind when your mom finds work in Reverse Falls, Oregon. There you meet Gideon and Pacifica Gleeful, two siblings who are desperate to get to the bottom of the strange occurrences.

They're both sure it all leads back to twins Dipper and Mabel Pines and they warn you to stay away from them.

But then you meet their assistant Will Cipher, a dream demon forced into slavery by a universal contract. As the two of you meet more and more, a bond forms.

Then the twins find out.
