Bill Cipher and Dipper Pines have a deal. In order to protect his family, Dipper agrees to become Bill's apprentice. But at what cost? What other secrets is Bill hiding behind his past? Who should Dipper fear? Bill or himself?

Slade offers Raven an apprenticeship, Raven loses control of her powers, a mysterious girl called The Shepardess comes to town, and something, or someone, is uniting the Teen Titan's enemies into a dangerous force. (Implied Slade/Raven, warning inside)

Bill didn't think much of the boy in the Mystery Shack, so he made a deal. Only he didn't realise the boy was strong enough to break it, and now there's a demon out there with power issues and a sister who insists on driving him crazy. (My take on the Transcendence AU. Rated T as I am paranoid.)

On a whim, Bill Cipher takes a short break and returns to Gravity Falls with the young Harry Potter under his arm. Ten years later, Harry arrives at Hogwarts with a love of physical pain, a stash of severed heads, and dexterity in demon magic. Inexplicably Human!Bill sometimes but not always. INCONSISTENT UPDATES.

Indefinite HIATUS

AU, in which the portals never reopened, leaving the mages magicless and disconnected from their friends. Five years later, three very different girls reunite to save a world they'd thought they'd lost forever.
