On his first day in Gravity Falls, Dipper saw a Ho-oh, and wished to have an exciting adventure. Minutes later, he found Journal 3, which is really the 3rd of 7 journals that he needs to destroy because the invisible wizard created them as horcruxes. Each journal represents a star in the Big Dipper, and Dipper's birthmark will disappear as Dipper destroys the journals. After Bill burned the first 3 journals, Dipper failed his quest, and decided to kill Bill as revenge, hence the name of the show: Gravity Falls.
