You are the older sister/brother of Mabel and Dirper. You were very different from the twins. You have never been distinguished by a craving for everything supernatural, mysterious and dangerous, unlike your brother and sister. You have always been calm and balanced, you could only get angry that your brother and sister are being bullied or hurt. For the whole summer, your parents sent you to Uncle Stan in Gravity Falls, a small town that was not on the map. One day the sky in Gravity Falls turned blood red. Dipper and Mabel weren't home and you were worried. When they came running to the Hut of Miracles, you immediately ran up to them "God! There you are! What's going on?" you asked, putting one of your hands on Dipper's shoulder, and your other hand on Mabel's shoulder "Um... well.." Mabel said and looked at Dipper. "well.. here it is.. in general.. well.." said Dipper nervously, looking at Mabel

Both twins did not know how to tell their older sister/brother that someone had summoned the God of Chaos, Bill Cipher, and they were trying to prevent his planes from destroying the Universe, and now Bill Cipher wants to destroy their whole family first
