Inheritance - An Undertale Fanfic

Chapter 1 - How It Began

Long ago, many years before monsters were imprisoned underground, a female skeleton by the name of Fawn was sitting by herself underneath a lovely willow tree, looking up at the clouds. She wore a grey and black checkered hoodie, with black shorts and black shoes to go along with it.

Fawn felt alone. Since the death of her lover, Roman, she had nobody by her side, and often came to this very tree to think about her past, present, and future. It was also under this tree that Roman had proposed to her days before he was killed. Fawn sighed. "Roman, you know I miss you and love you with all of my heart, right?" she spoke softly.

She kept talking to herself, hoping the spirit of her love could hear her, until she eventually ended up crying. Fawn felt so alone. "Why, why would someone take you away from me..." she cried. "What wrong did you ever do to deserve what happened to you, Roman..." She kept crying until she heard someone sit down beside her. She looked up, tear tracks staining her face. A handsome skeleton sat beside her. He wore a black cape with a red underside, along with a dark grey turtleneck, black pants and black shoes.

"Hi there, miss. I'm Montego," he said sweetly, holding out his hand. Fawn smiled shyly. "I'm Fawn," she told him. Montego smiled back, revealing pointed canine teeth. "What a lovely name," he remarked, prompting a blush from Fawn. "Why are you so sad?" he asked. "My fiancé, Roman, died a year ago on this day," Fawn said quietly.

Montego put a hand on her shoulder and sighed. "I'm sorry for your loss," he said. "It's alright, Montego," she said. "It's been a year, but I still feel so alone without him. He filled the void I had in my heart for so long, and without him here the void is back. I'm scared it might never be filled again." Fawn broke into tears again, hugging her knees.

Montego patted her shoulder reassuringly. He had seen her out in the street earlier that week, and had instantly fallen for her. She was nice, gentle, pretty, everything. "If it's of any consolation, I think of you as a remarkable person, even if we did just meet," Montego said with a sweet smile. Fawn sniffled and smiled. "Thanks, Montego," she said.

Years later, Fawn and Montego were married and had one little girl named Arista. Arista was cheerful and bubbly with a great sense of humour, like her mother, but inherited a not-so-secret gene from her father: vampiric desires. Montego, you see, was a normal skeleton who was bitten by a vampire about two months before he met Fawn, and had become a vampiric skeleton as a result.

He never infected Fawn, but instead went around trying to get his nutrition from normal sources, like food, although he had to eat and drink almost twice as much to get proper sustenance due to his... being-a-vampire thing. Arista, however, didn't know she was a vampire until she was 10. When she was told by her father, she was shocked at first, but overall thought it made her unique.

When Arista was 23, she met another skeleton by the name of Dextor, and had a child with him at the age of 25. The child was named Cooper, and he was not actively vampiric like his mother, but was a carrier, which meant any children he had would have the vampiric gene that could either actively show up on them or they could carry it down to future generations.

Fast forward just over a hundred generations, long after monsters are imprisoned under Mt. Ebott, and a baby boy is born to W.D. Gaster, a vampiric carrier, and Arial, the two only surviving skeletons — the rest had died in the War of Humans and Monsters long ago. "What should we name him?" Gaster asked Arial. "Maybe... Sans," Arial responded. Her lover smiled. "That's a wonderful name for a wonderful child," he said before kissing Arial's forehead. She smiled happily.

Years later, they had another child, another boy, and brought him home to meet his older brother. "Sans!" Gaster called. Sans, who was now 8, was playing with cars up in his room. "What is it?" he called back. "Come meet your new baby brother!" Sans ran downstairs excitedly and looked at the tiny bundle of bones with curiosity. "His name is Papyrus," Arial said sweetly, passing the baby to her son.

Sans held Papyrus carefully, who was swaddled up in an orange blanket. When he woke up, the first thing he did was smile. Sans looked overwhelmed with happiness that his brother liked him. "You'll be a wonderful big brother, Sans," his father told him. Sans looked up at his parents. "I promise that I'll always protect him," he told them. They smiled proudly at their son.

15 years after that, Arial had died of a disease and Gaster had gone missing, but Sans and Papyrus were still taking phenomenal care of each other, having become very heavily co-dependant. They still lived in the same house in Snowdin that they had grown up in, and still had everything from when they were babies, keeping treasured memories of when their parents were alive.

Papyrus had barely changed his childish bedroom decor, and he even still had the action figures his parents had bought him as a child, along with ones from Christmas and the teddy bear Sans got him when he was 2, the year their parents vanished. They knew the family secret and the history of their bloodline, but only one of them knew that the long-inactive vampiric gene had recently shown up.
