It was 1952 when Silas, who seemed to have died, suddenly turned up alive and well again. It’s just his posture, smile, pale skin, everything has changed. Because Silas is really dead and his dead body was controlled by Bill. All this was in order to deceive people and hypnotized people with his speeches:

"Say, folks, gather round, thank you ma'am, spit out that gum, junior. My names Silas Birshtree, and I was just passing through when I noticed a very pressing problem: This town only has three wells! Well, well, well, that won't hold water! (townsfolk laugh) But seriously plasma bags, if you're dim enough to laugh at that tripe then you're going to love what I'm about to shove down your throats: The secrets of the universe! I may look like an meat automoton but I was recently granted otherworldly insight into the nature of reality by an all-seeing eye narned Bill Cipher. You have primal needs for chaos that are being repressed! Destroying is a form of creating! Assert your will in defiance of entropy! Punch through the throats of your opressors and baptize yourself in their blood!"

Having founded a cult in which they were ciphertologists his popularity spread throughout the city Kansas. Silos skillfully manipulated people and found his own approach to everyone, even promising life on the moon and the ability to explode objects with the power of thought. Soon the city changes its name to BillVille. Laws were prohibited, it was also forbidden to go to the hospital because pain is fun. Everyone was brainwashed, so no one saw anything wrong with his plans, and the cult itself began building the portal, which was what Bill Cipher himself had planned from the very beginning. The cult itself shaved their foreheads and drew an eye on it, pulled out the teeth of animals, listened to jazz and did other strange things.
