(Completed/Edited) Will and Bill are known as the twin ciphers, never to be separated. No one knows when or where they came into existence. They are feared throughout the multiverse, but what made them this way? Bill is reckless. He doesn't know better, and always gets himself into trouble. His best friend and non-blood related brother, Will, always trails him everywhere, sometimes pitching in on his brother's antics. Lucky for them, they have a fallen angel and their uncle to look after them. Surely nothing bad can happen?

(Completed/edited) The Cipher twins, years upon years later, now are reunited. Only now, things are only beginning to pick up. With Bill's failed takeover on Gravity Falls leaving him without friends, and Will being on the run from his old masters, the two have a lot to catch up on. Only it seems that following Will's return, his health took a turn for the worse. Now it's up to Bill to save his brother.

(Completed) It's been nearly a decade since Bill's death. Tad Strange and Elizabeth have returned to help Will find his way, but the problem is, Will isn't the same. He's seemingly become cold and emotionless. He took over Bill's place as ruler of the Nightmare realm and rules with an iron fist. The Pines Family, still in Gravity Falls, is still working in the supernatural field. Dipper, expanding his horizons, has focused his studies on the Cipher Family. His discoveries lead to a shocking reality. Bill Cipher may just be alive.
