(Alright guys this is my first fanfiction and english isn't my native language...so be prepared. I don't own any of the caracters but thought of the AU on my own. Also i'm sorry if the chapters are too short.)

Dipper Pines, a young boy with an harsh fate. In his culture the people worshiped a certain demon like a god and every 50 years they offer a sacrifice to it. A human sacrifice to be exact. And this time the oracle chose him.

"Bring me a boy who's marked by the stars" These few words seperated Dipper from his family and the rest of humanity.

Chapter 1

The Brunette sighed softly as he dressed himself. He looked around the room and bit his lip. This was the last time he'd be in here. Why you ask? Well in his culture the people worship a certain demon like a god and every 50 years they offer a sacrifice to it. A human sacrifice to be exact. And not just any human. An oracle would foretell who they had to look for one year before the actual ceremony. "Bring me a boy who's marked by the stars" the oracle had spoken and instantly the people started to look for the boy. Half a year later they found who they were looking for in a small town called Gravity Falls. And now this boy had to get ready to leave his home forever. "Dipper! It's time!" His great uncle called from downstairs. Another sigh escaped the boys lips as he slowly walked through the door down the stairs "here I am great uncle Ford..." The old man nodded and guided his nephew outside, where a carriage was waiting for him. It would bring him directly to the temple. He had been there already once a while ago so the oracle could tell if he was the right person or not. Now it was time for the actual sacrifice. After one last look over his shoulder Dipper got into the carriage. With the door his eyes closed aswell. No one would probably miss him. Maybe his sister but she'd get over him. The teen took a deep breath as the carriage finally started to move. This wouldn't be a long trip but definitly a dreadful one if he stayed awake any longer. He leaned back and soon fell asleep. To Dipper it felt like only a few seconds had passed since he had gotten into the carriage back in Gravity Falls but now his coachman was shaking him awake. They had just arrived at the temple. Slowly Dipper got out and looked around. Just a few steps away stood a priest. "Hello Mr. Pines. Please follow me." Was the only thing he said to Dipper who just nodded and did as he was told. The rest of the day passed by in a rush for Dipper. He remembered a few rituals, tests and examinations but now he was ordered to sleep so he could get up in the early morning. At 7 am the ceremony would start and one hour later Dipper would be gone. He'd be with their so called god. For the first time for years Dipper cried himself to sleep. He didn't know how long he cried but he must have fallen asleep at some point because someone just harshly woke him up. With a soft groan the teen sat up. "Please get ready Mr. Pines. Only 20 more minutes until the ceremony begins." That was the only thing they told Dipper before they left. Just one servant stayed to help Dipper dress up. He looked at the elegant robe and all the jewlery and shook his head. Eventually he got up and cleaned himself before stripping. When the time was almost over he was finally ready. Another priest guided him to the 'Gate' and the ceremony started. People danced around him to strange music and soon blue flames engulfed him. Dipper cried out loudly and tried to protect himself but the flames didn't hurt him. They actually felt nice. But that didn't stop the male from panicking. Oh no. He tried to escaped but failed. The dancers stepped away and the music stopped when blue chains started to wrap themselves around Dipper and pull him back into the flames. He fought back and struggled wildly but nothing worked. Dipper could feel how he slowly became unconscious. The last thing he heard was a soft laugh followed by a mocking voice "Well, well, well who do we have here?" He tried to look up but everything just went black.
