Thanks to The Book of Bill, we finally know what happened to Bill Cipher after the Pines family saved the day.For me, the series finale, "Weirdmageddon 3," boasts some scary Gravity Falls moments ...

Gravity Falls’ big villain, Bill Cipher, is getting his own book written by series creator, Alex Hirsch. And it’s for older readers! Out in July.

But Bill Cipher, the inter-dimensional demon bent on taking over the multiverse, is back in action — or at least, he’s back in a new book penned by Gravity Falls creator, Alex Hirsch.

Congratulations on finding the Bill Cipher statue, Bill’s final resting place! Whosoever finds this treasure is hereby the new “Mayor of Gravity Falls”—so use your title well!
