Didn't we always promise each other…. that we would always be together?

It was a clear summer's day in Gravity Falls, the sun above bathed the surrounding forest in a angelic golden light, tall pine trees soared majestically over the forest floor and chirps and croaks could be heard from the bustling wildlife of the nearby bushes and shrubs. By the side of a clear and cool stream, resting on a large boulder slightly covered in damp moss, a boy perhaps of 17 years of age sat, fiddling with his over worn blue and white cap with a faded blue pine tree nuzzled in the center of the cap, he wore a slightly weary expression, with messy brown hair that reached past his ears, which could be the result of the nearly 5 hours drive to get here. Donning a red t-shirt with a dark blue hoodie, he brushed off the moss off his beige pants and strolled towards a girl not too far away from where he was sitting. His name? Dipper Pines.

Walking over to the girl, his shoes slightly crunching over the leaves littered on the forest floor, he smiled as he watched the girl skip a few stones across the stream. She had long, slightly wavy brown hair that tumbled below her shoulders; she wore an oversized red sweater, her personal favorite, with a crimson butterfly stamped in the center, she also donned a knee length beige skirt, with black shoes and ankle high socks. She was also 17 years of age, but older than Dipper, she would often tell. Sitting down next to her, Dipper smiled and threw a stone into the stream. Her name? Mabel Pines.

"Remember we used to play here all the time?" Mabel said. "Yeah, solving mysteries and finding hidden secrets, those were summers that I won't forget…" Dipper said reminiscently. "You better not!" Mabel giggled and playfully punched Dipper in the arm, causing him to mock groan in pain. If they weren't side by side, it would be hard to believe that they were twins; radically different in many ways, Dipper was usually the calm, quiet but clever one while Mabel was fun going and very peppy and energetic. "Sadly… it'll be gone soon…" Mabel said suddenly with a twinge of sadness in her voice. Dipper remembered that the surrounding forest, where they played over the summers, was going to become a dam very soon, and this maybe the last time, they would see the forest… Dipper soon became lost in thought, remembering how he and Mabel would venture from their home in the not too far Mystery Shack, to this very forest where they would use the journal, a book containing the secret findings of Gravity Falls to hunt for monsters or just plainly fool around, he reached into his jacket and pulled out the journal, now withered over the years and flipped through the pages slowly and sighed. "Mabel, do you think…" but before he could finish his sentence, he suddenly caught Mabel as if she were in a trance, chasing after what appeared to be a crimson butterfly. "Mabel!" Dipper yelled, but she did not respond, prompting Dipper to quickly chase after her into the depths of the forest.

Running after Mabel, Dipper puffed and panted, chasing after an unresponsive Mabel. 'Mabel! Where are you going?" he yelled. He continued running after her when all of a sudden, the forest became pitch black, he became disorientated, if was as if the forest was caving in on him. The chirping and the croaks stopped, all he could hear was the mournful whistling of the wind. "Mabel!" he cried as he spotted her running after the butterfly. He chased after her, heart palpitating, his actions became more frantic, his vision suddenly become more distorted, Mabel's figure was flickering between her and another girl dressed in a snow white dress, and when he finally grabbed Mabel shoulders, his vision flashed, a brief image of him strangling Mabel and then, all became darkness.

Dipper gasped and opened his eyes, he was back in the forest and it was strangely night time, the moon above glowed eerily as it illuminated the forest floor. Dipper looked at his shaking hands, "What was that?" he asked himself. He looked around and Mabel was nowhere to be found, he called her name, but silence was his only reply. Suddenly, Dipper saw a path that lead uphill, seeing as Mabel may had been there, Dipper rushed up the path, worried about Mabel's safety. Approaching near the top of the path, Dipper reached a large gate, just in front, a boy in an oddly similar white costume, that resembled a yukata, the male version of the kimono. His face buried in her hands, weeping. "I'm sorry… I'm so sorry…"the boy kept repeating over and over. Dipper tried to speak to him, but there was no reply. Nervously walking past the boy, he finally reached what appeared to be a plateau, several torches lit up the area, casting a glow onto the nearby surroundings, the plateau looked over a village, not any Dipper seen before, it looked dark and desolate and an eerie miasma blanketed it. Overlooking the village, Dipper saw Mabel standing there motionless. "Mabel…" Dipper called out cautiously. She turned around and several crimson butterflies flew from her chest, fluttering away into the cold night. "The lost village…" Mabel uttered under her breath, as her eyes returned to the sight of the lonely village in the endless night.
