(Y/N) had a normal life in the second dimension with her family and friends, and of course, her best friend, William.
One day, William finds a cave with ancient writing in it, but once he repeats the words, he had accidentally summoned and was possessed by a demon and becomes the famously evil, Bill Cipher.
Filled with insanity, Bill wreaked havoc on his hometown, and asked (Y/N) to rule beside him, for the demon fell for (Y/N)'s beauty.
Sadden by her friend's transformation, (Y/N) rejected and fled her town, and soon her whole dimension for Bill, now in anger from her rejection, destroyed their home world.
Y/N is found by the Pine Twins, Mabel and Dipper, and taken in to their home, the infamous Mystery Shack.
But when Bill enters this dimension and finds out his lost love is here as well, he will do anything he can to make her his.
((TOO LAZY TO EDIT))
(Y/n) (l/n) has lived in Gravity Falls forever, but moved away for a year to help out at her Grammy's the year the Pines twins visited. She's always enjoyed monster hunting and the paranormal, but since her father died she's pretty much given up on it. And not to mention she's vowed never to speak again. But now she's back in her hometown, and so are the twins!
Bill Cipher is a dream demon who tried to take over the world, but was trapped in a statue in the woods of Gravity Falls. When (Y/n) finds the statue, what will happen to her? What adventures will she and her new friends embark upon?
((Sorry this summary is so bad but hopefully the story is better!))
