Hi!!!
Today I want show you my AU. Name is "Magic in Gravity Falls". It's about future summer, when Dipper and Mabel come back to the town they get to know they aren't alone. In Mystery House is a girl, that was adopted by Melody's best friend and she is in Gravity Falls for summer too. She's name Krystal. Mabel of course makes friends with her but Dipper doesn't trust her, for him she is dubious but she doesn't care too much about it. In the evening of first day she start discover powers. The big and first powers she discovered was the power of water and fire but she hides it 'cuse she's thinks when she tell about it they start to be scare of her and she isn't like there where she lives, that are reasons why she hides her powers. The second day to Gravity Falls arive Stan and Ford, that was a big suprise. Ford accidentaly find out Krystal's powers. After quarrel with Dipper she decided to tell him about powers, he's shocked of it but he appreciated what she's done to him and he started to trust her a bit and he tell about his secret too. Mabel and Pacifica are friends now. Krystal with Dipper and Ford secretly uncover her powers and new weird things in Gravity Falls reliving adventures.

She seems like an interesting character. You should make a wiki for her
