You moved to gravity falls when you were four years old, you noticed a bunch of weird stuff with the town and thought nothing of it, until one day two kids came, Dipper and Mabel Pines, they stayed at the Mystery Shack with their Grunkle Stan, you became friends with them and they opened your eyes to the mysteries of Gravity Falls. One day it was normal, summer was coming to an end when suddenly something happened…Bill had managed to break the rift between realms…the sky became red monsters appeared everything became chaos and basically upside down and eye bats would turn people into stone and take them to Bill’s tower…everything was awful…
It was the final day of Weirdmageddon, Bill has just been defeated and everyone was being reunited with their families…except you…your dad was the only one you had left but he sacrificed himself for you so you wouldn’t get eaten…he got eaten by a monster because it was either him or you…you’re now alone and you need to find a place to go…but where?
