UnderHollow[]

Intro[]

Hi everyone, once again this is a WIP AU that I made a few years back. This is in the form of a story instead of an info page so pls don't be mad... Also sorry for the inactivity but I've been rather busy on some other wikis that I'm a part of!

Just some info first, UnderHollow is almost identical with Undertale except all of the monsters we're familiar with were born on the surface AND THEN the war happened... The rest of the story takes place a long time afterwards so just so you're aware, in UnderHollow monsters can live hundreds of years before eventually dying and human-monster hybrids that are BORN can exist...

This really sucks so don't be mad...

The Story[]

Celina looked out the window at the sleepy little town of Fir Hollow. Her old manor house high above the town was set on one of the many mountains that surround the town on four sides. The front of the house looked out across the town towards the small harbor, the only way out of the town. “Miss, the mayor is here to see you” her elderly butler Marten stood in the doorway of her Georgian bay-colored room with its flora print. “I’ll be down in a second, tell him I’m in the bath or something, I don’t care.” She replied, still looking out the window. “I understand, madam.” He turned and left, closing the window behind him. Celina sighed, she had rejected the mayor several times already and he didn’t seem to want to give up. Celina turned from the window to the trapdoor set in the wall next to her bed. She hadn’t been behind the door since her son Edward died, she kept it locked to keep what was back there from escaping. After all, her days as a scientist had passed long ago when she had been younger.

The small town of Fir Hollow had been founded three hundred years ago, the outcasts and prisoners who had been taken to the little bay area built the town for themselves. Though it was on American soil, it was not an American town, the town had its way of life and America was never part of that. Amongst the prisoners and outcasts, was a little girl named Celina. Celina looked no different than any other child that you would find in a little settlement like Fir Hollow, which back then was called Freedom’s Haven. But she was different, she could see things that weren’t there, the spirits of the dead and the slithering shadows that ate children. The giants in the mountains, the star-covered deer of the forest, and the rainbow serpents of the bay. She befriended and studied them, gave them names, and nursed them when they were sick. She was a kind child who received blessings from the creatures she befriended and the spirits she helped pass over. Long life, good luck, eternal youth, and boundless knowledge were given to her in little boxes that she was instructed to only open when she felt the time was right. She built a little trapdoor into her bedroom wall behind her bed. She kept the boxes and several injured pixies safely in the room.

She fell in love with a skeleton who called himself Sans, they loved each other deeply and were married on a warm summer afternoon, surrounded by the creatures and spirits Celina had cared for. They added additions to Celina’s lonely manor house, each new room made for injured creatures to rest in. After seven years of marriage, the town began embracing the beings that lived in the forests and mountains around them, marriages between the supernatural and the humans became common and hybrid children became common as well. Celina began to feel alone in her giant house when the monsters and spirits were not there, she wanted a child to love and nurture. She begged Sans to use his magic to create for them a child, but he insisted that it was dangerous, that his father had done the same thing when he created Sans and his brother. Sans said that it had worn down his father’s sanity and had left his father with two holes in his hands. Celina continued to beg Sans until he finally relented and shut himself in his lab when three days later he returned from the room with a little boy that Celina named Edward.

They lived happily for seven more years until the town went to war with their monstrous brethren and all of the creatures that made the town special were locked deep underground. Celina and Edward, separated from their husband and father, mourned the loss of the town’s magic. The pixies and the gift boxes remained locked in the secret room in Celina’s room. Edward would play with his pixie friends and eat the sweets that the family cook Annabella made. But one fateful stormy night, Celina was not home, she had entrusted the pixies with seven-year-old Edward. “Keep him safe and do not let anyone in unless they are me. I trust you all to know whether or not someone is me.” Celina instructed. The pixies had gibbered their agreement in the fuzzy language of old. Little Edward on the other hand, did not know of this rule. A skeleton appeared at the door at exactly seven that evening, looking so much so like Edward’s father that he let the skeleton in the house. But it was not his father, the hood of the skeleton’s jacket was drawn over his head and dust coated the sleeves. A tattered red scarf fluttered from around his neck, set over his hooded jacket. His eyes were wrong as well, unlike his father’s blue eyes, this man’s eyes were red and purple. Edward knew had made a mistake letting the stranger in, but it was too late and the pixies were dead. The door slowly closed as if by magic…

Twenty-seven years had gone by in the blink of an eye for Celina, every year on the night her son had been murdered she would visit his grave. He had dusted, so there was no body to bury, but she didn’t want the townsfolk to question the lack of a body. Since most had never seen Edward, she had taken a random body from the town over the mountains and had buried it instead. She grew to hate caring for the house and the gardens, so she hired a butler and a gardener to take care of those things. She spent most of her time now secluded in her library and staring out her bedroom window. The skeleton who killed her son left something behind, a phantom of a slimmer skeleton with a thinner and longer head than Sans, she locked it behind the trapdoor so the monster who killed Edward would never reunite with it. She wanted him to suffer just as much as she did, no matter how cruel the method was.

She turned back to the door of her room, “That man won’t give up will he?” She sighed, slowly pulled open the door, and glided down the hall to the stairs. She caught a glimpse of herself in the stairwell mirror as she moved gracefully down the staircase. She had braided her long black hair and warped it into a bun, a crown of silver flowers keeping it in place. Dark blue eyeshadow accented the pale white of her skin and the red of her lipstick drew the attention of all who saw her. The sky-blue silk of her gown paired with the short skirt and the long billowing sleeves clashed and yet, at the same time they went together and made her look even lovelier. “No wonder the Mayor loves you so much.” Chelonia scoffed. Celina had hired Chelonia as a maid to help Marten around the house, he was getting old while Celina still remained young. She had hidden in the house, coming out every thirty years to make it seem like she was a different person. She had told only Marten and the family cook Marley about the fairy boxes behind the trapdoor. She had already opened the youth, longevity, and knowledge boxes. She could hear Mayor William laughing drunkenly from the hall.

“Ah, if it isn’t the beauty of Fir Hollow herself, the immortal Celina Gaster! Well Miss Gaster, will you marry me? I’ve asked so many times and I’ll keep asking till you say yes.” the Mayor exclaimed. Celina chuckled, “And what makes you think I’ll say yes, you awful pig? No woman would ever marry a man as pig-headed and selfish as you! You’re rather fat because of your many feasts, all of that food could be going to the community.” The Mayor tried to protest, but MRS. Gaster continued. “Not only that, but your little parties are a waste of community funding that could be going to improve the school systems. I don’t understand why you can’t take no for an answer, you horrible monster.” She had never lashed out at the mayor during his previous visits, he no longer found her attractive in a kind sense. She seemed more like an overbearing goddess than a human woman now, though that was most likely what she was. The mayor suddenly was standing at the edge of the manor grounds, not knowing how he had gotten there. “If you come back one more time, I will not hesitate to kill you ‘Mr. Mayor’. Now be gone before I kill you now.” Her voice boomed from the sky, and the mayor turned and fled not wanting to be near the house or its captivating gardens any longer. He feared becoming lost in the maze of hedges and flower bushes, he feared that something hungry lurked hidden in the leaves and that the lady of the house really would kill him. So, he never returned to the estate and made a point to do anything that would keep him from being killed.
