The Cullen family left Forks, Washington nearly one hundred years ago.
Carlisle and the others left to live in Denali until Jacob graduated high school. That way Renesmee could be with him until he could move away from home. And Bella and Edward stayed because Renesmee couldn't leave home yet. After that, they moved to Denali with the rest of the family.
Jacob and Renesmee got married when she was eighteen. Jacob was still seventeen years older than her, and when others saw the couple they gave menacing glances. But Renesmee always kissed Jacob on the cheek and smile at them "He's a millionaire, and you obviously haven't seen him in bed!" She got her Uncle Emmett's sense of humor.
When Nessie was born, Charlie was tricked by Jacob into thinking that the Cullens were werewolves too. They convinced him that they were just a different 'breed' than the Quileute tribe. The Cullens could live forever. He knew that Bella chose to be one because of her love for Edward, and that she has known from the beginning. He accepted all these 'facts'. And he eventually got over the fact that his daughter never grew older than eighteen. When it came time to tell Renee, Charlie and Bella thought it better to just not tell her at all. But Renee was Bella's mother, and she didn't know about Nessie. They all decided to fake Bella's death. With the help of Carlisle and his 'home hospital', Renee watched her only daughter 'die' from cancer. Along with Renee, the death of Isabella Marie Cullen was made known to the world that day. She even had a death certificate. Alice kept a view of Renee the rest of her life. But Bella, Edward, and Nessie all went to see her a couple times a year. Of course, they couldn't be seen, but they could see her. It broke her heart, and it broke Bella's heart to see her mother like that. But she knew it was for the best, lest her mother be changed into a vampire or killed. And Renee died young, her days of erratic behavior caught up with her at the young age of forty-three. She was cremated and spread into the ocean. Bella had seen her the day before her death thanks to Alice, and had said her goodbyes then. Renee actually saw Bella when she said goodbye, but due to her illness, when Renee told everyone that Bella wasn't dead, that she was just here saying hello to me, nobody believed her.
Bella, Edward, and Renesmee went to see Charlie as often as they could. They always drove whichever newest model of sedan Carlisle had bought. The windows were always tinted, and the family of vampires always came at night and left at night.
When Billy died about a month after Jacob and Nessie's wedding, the newlyweds stayed on the reservation nearly two months. They then moved back to Denali. But three years after that, Charlie died. Bella was nearly forty years old, but to the world, she was dead. The family was terrified about returning back to Forks for such a public event. Charlie was after all, a well respected man in the town. And it would be no surprise if the entire town showed up at his funeral. But he had left everything in his will to Renesmee. Who had aged to eighteen, which was the age when her mother gave birth. That was the end of her growth spurt. So Nessie still had the appropriate looks for her age. She was twenty one, and she was fully able to carry out all of Charlie's last wishes. But Charlie knew that the family was living in Denali at the time and wished to be cremated. He wrote in his will that this was 'an homage to his favorite person in the world and her new family'. Some people thought that this meant Renee because she had been cremated as well. But the people that it mattered to knew that it was for Bella and Nessie, because they could only be killed by burning their bodies as well. Nessie went to gather his things and his ashes and took them to Denali. She sold the house and gave the money to the reservation fund to keep First Beach clean.
Jacob died when he was sixty two. The Cullens took him back to La Push for the funeral. Afterwards Nessie ran away for nearly ten years. And so the Cullens moved to Toronto in attempt to leave Nessie and Jacob's lifetime of memories behind. Nessie eventually returned to their home in Toronto after that.
Another twenty years after moving to Toronto, Bella was ready to go home to Forks again. The Carlisle decided that after eighty years of absence that it was safe to return to Washington. There was the chance that story of a gorgeous 'Edward Cullen' and his wife, 'Bella Swan/Cullen'. He thought that their female classmates told the story of the whirlwind romance, of Edward's good looks, and of Bella's unworthiness of him. He also thought their male classmates told the story of Bella's good looks, and her unworthy husband Edward. Alice saw visions of a picture that Angela had of herself, Bella, Edward, and Ben at graduation on her family home that her grandchildren were quite fond of. Mike had kept a school picture of Bella in his wallet the rest of his life, much to the dismay of Jessica. But Jessica knew that Bella had died and allowed the picture to be put in the family album after his death. There were still remnants of the family in Forks, Washington.
But this story brings us to today: the day that the Cullen Family moved back to Forks. Dr. Carlisle Cullen and his beautiful wife Esme Cullen; Jasper and Rosalie Hale, Esme's niece and nephew; Emmett, Alice, and Edward Cullen, Carlisle's adopted children; Bella Cullen and Renesmee Black, Carlisle's nieces. Yes, this large, but happy, family of vampires was coming back to Forks. Today.
