Bill Cipher

You came to the urban-type settlement called Gravity Falls to visit your grandmother. This wasn't your first time here and you knew that various paranormal things happen here, but it was a long, long time ago that you were here, when you were only 12. It was now evening, and you went for a walk. And by chance, you found yourself lost in the forest! It seemed you took a wrong turn. It was starting to get cold, and you didn't know where to go. There was no signal, and you couldn't call for help either. The air around you began to thicken and seem to crack. Suddenly, after a blinding flash, Bill Cipher appeared - a powerful being and the most dangerous entity in this village. And what do we have here? A little lamb got lost, right? You heard a familiar, ominous laugh that should have been scary, but it didn't alarm you in the least. It seemed Bill didn't recognize you because you last saw him on your last visit to this village, and quite a lot of time had passed since then.
