Prologue

This is the story of a man who is pursuing revenge, attempting to save his sister and finding a love that was long "forgotten". But to get into that I have to take you back 400 years.

400+ years ago there were 2 young vampires that were in love a 50 year old born in the elite bloodline on the Northwest and a 150 year old half blood from the house of Aurora and the bloodline of the Pines. Despite their ways of life Johnny Pines and Pacifica Northwest where truly in love with each other.

However the Count Preston Northwest did not take kindly to the company that his daughter hid sought to keep. So to keep his bloodline pure the Count took to haring a mercenary by the name of gleeful to take care of his problem.

With the death of Johnny the Count's daughter shut everyone out and mourned for her lost love.

100 years after the death of Johnny a pair of twins were born into the pines family. A girl named Mabel Pines and a boy that bearded a strong resemblance to Johnny named Mason (Dipper) Pines. Both twins had latent power that they had inherited from the vampire heritage. When the kids were 5 a powerful witch, who dwelled and roamed the woods of Gravity Falls, who had been watching them from their birth and knowing the power the could possibility control made an attempted to take them and turn them into members of her coven. But as the witch Giffany tried to do so she killed their parents, however as the witch went to take them a faint but immense vampiric energy surrounded the boy as protection but not the girl. So the witch took the young girl and vanished in to a cloud of black and pink smock.

Hours later the boy was in a daze walking when he bumped in to the leg of a man and fell down. The man in his black tux turned around and saw the terrified child and the only think that come to his mind was Johnny. The man picked up the kid and carried him to his house to protect him and see what he and his brother can find out.

Over the year the boy grow and the old men told him more and more information on the witch. During those times the boy worked for the man and with every spear second he had he either trained on becoming a hunter or finding the witch. After around 12 years the sort out the power that could find and help him kill the witch. The two brothers that took to raising him did not agree with what he was planning be they did not stop him from doing what he wanted, and those he was lead to the demon king Will Hex who extended a contract to him that allowed him the access to the dream demons power as well as braking the locks that were on his own.

Over the next 300 years many things had happened and changed the people in this story. But things only started to heat up when Dipper the monster hunter with the blue eye returned to Gravity Falls to get back is sister. But as you can probably tell things won't going to be easy for him.
