Chapter 1: The Birthday Wish

Frisk slipped on her favorite red shirt and red jeans before putting on her red sneakers, glancing at herself in the mirror and smiling, tracing the red wave patterns on her clothes. "I'm now ten-years-old," she said excitedly before heading downstairs.

When she got to the kitchen, she heard her mother humming a familiar tune and smiled before joining in with the lyrics to "Let It Go," one of her favorite Disney songs. "Is it almost time, Mom?" She asked hopefully.

"Yes, sweetie," Amelia said, smiling down at her daughter. "Your father is coming through the front door in about five seconds."

The door opened. "Make that two seconds," the woman corrected with a smile as her husband came in.

"Daddy!" Frisk exclaimed happily, running up to him and he lifted her up into his arms.

"Hey! There's the birthday girl!" Her father, Joe, said with a smile. "Come on, let's go put in the movie while your mother gets the cake."

The young girl nodded, following her father out to the living room before pausing to take a look at a picture on the table. Her smile faded a bit as she looked at it.

It was of her mother and father, along with her and her older brother Stephen when he was thirteen years old and she was five. He disappeared five years ago and no one had seen him since. She missed him and sighed, wondering why he disappeared. No trace had been found of him, which made her and her parents hope he was still alive.

Amelia then brought in the cake and Joe lit the candles. "Okay, sweetie, make a wish," the father said to his daughter.

Frisk closed her eyes, pausing for a moment before deciding on her wish. "I wish Stephen would come back home soon," she whispered softly to herself before blowing out the candles and the cake was cut. The ten-year-old hoped that her wish would come true as she really missed her brother and knew her parents missed him too.

Far away, deep underground, a young male looked into the portal in time that the chained being beside him had created. "How sweet that she used her wish for him," he said with a cruel smile before turning and going over to his throne, sitting down on it. "So, she wishes to see her brother. Quite a stupid birthday wish, honestly."

"I doubt the kid thinks so," said another being nearby, a bracelet-like chain around one of his ankles.

The young male glared at him. "Mind your tongue, skeleton," he said before turning to the chained skeleton who was still holding the portal open. "Alright, skeleton, bring Frisk here to the Underground," he said.

The other chained beings in the room gasped in alarm. "No," the tall skeleton said firmly.

"I think you forget you monsters are my slaves," the male said. "I am your ruler and you were given a command. Now do so, or little Alphys will suffer if you disobey."

Gaster's face fell, as did the other monsters' faces. Their self-proclaimed master smiled. "Yes, she will be punished if you don't obey," he said. "But…do as I say and Alphys will be spared my wrath."

He pet the yellow dinosaur's head and she flinched, scooting away from him and into Gaster's arms, making the young male laugh and the skeleton sighed, lifting his arms that were bound by the heavy chains that kept his energy mostly drained. He concentrated and successfully teleported Frisk into the Underground, but doing so badly drained him and he fell to his knees. "Master, I could only teleport her to the Ruins," he said.

"Perfect," the cruel man said with a cruel smile, looking at the chained monsters around him. "You will guide Frisk here. Oh, and see if you can find that stupid Muffet. She can't guard the Underground forever, since she's weaker than the rest of you."

He then frowned. "But that bite of hers," he growled.

"Really bites, doesn't it?" The shorter skeleton who has spoken earlier said, matching the young man's glare without flinching.

"Defy me again and Alphys will get locked in the dungeon," he said.

All of them flinched at that because the dungeon was just a small, dark hideaway and whoever went in there would be given no food and water for however long their cruel master deemed. The young man now snapped his fingers, freeing the monsters from most of the chains, but keeping the bracelet-like chains on them. "Now, you know your orders," he said.

The others dispersed, stopping briefly to hug Alphys, who drew comfort from them. The hurt looks they gave her made her sad, but she gave them a look that told them she didn't blame them for the cruelty the master did to her. "Go help her," she whispered softly to them. "She's going to need it."

They headed out to do so, the walk tedious as they felt their very small, precious glimmer of hope get smaller as they feared for not only Alphys and themselves, but for the young girl too.

Who is the monsters' cruel master and why does he want Frisk? Stay tuned! :)
