The date was August 31, 1999. The town was Piedmont, California. And on this particular day, two miracles were about to be born in the local hospital.
"Congratulations!" the doctor said. "It's a boy and a girl!"
Mrs. Pines held her newborn son in her arms. "Look honey," she told Mr. Pines. "He's perfect."
"Indeed he is," Mr. Pines said. "Absolutely perfect."
Silvia noticed the baby girl in the doctor's arms. "What about his sister?" she asked. "She seems perfect as well."
But one look on the girl's forehead made Mr. and Mrs. Pines disgusted. "That girl is a freak!" Mrs. Pines exclaimed. "Just look at her forehead!"
All Silvia saw was a birthmark that resembled the Big Dipper. "But it's the most beautiful marking I ever saw," she said.
"Doctor, my wife and I feel it's best for that freak to be dumped into some orphanage," Mr. Pines said as Mrs. Pines nodded in agreement.
"Oh no," Silvia said. "If you won't take the responsibility of this precious little child, I will take matters into my own hands and raise the child myself."
"Great," Mr. Pines said. "Good luck raising that freak."
But Silvia ignored her nephew's cruel words, looking in awe at her great-niece. She was so beautiful with soft brown hair and beautiful blue eyes, with the birthmark on her forehead making her look even prettier. How could anyone be so unkind to reject someone with such incredible beauty?
"Ms. Pines, what would you like to name the girl?" the doctor asked. "Your niece-in-law and nephew have decided to name the other twin Marcus."
"Nova," Silvia decided, her fingers lightly touching the birthmark as the baby girl cooed. "Her name will be Nova Pines."
A/N: I know this chapter is short, but it's only the prologue. I will make longer chapters as the story continues. And yes, this is based on the fan AU where Dipper and Mabel were separated at birth and Dipper was left under Stan's care. I figured I might as well make a genderbent version of this.
