Chapter One

"Ugh, where am I?" You asked. The last thing you remembered was that you were off to your friend's house and you felt yourself fall.
You see a small flower in the distance and as you got closer, you realized it had a face. You curiously went to the flower and it's eyes opened.
"A human?" It asked. You fell back. It had a menacing grin.
"The last human that made it here didn't fall for my trick, so you guys have gained intelligence, which means, you wouldn't fall for it either!" It said. You walked backwards, keeping your eye on it. You bumped into something behind you. You turned around and it was a goat lady.
"Flowey, leave her alone." She signed, walking you beside her.
"Welcome. What is your name? My name is Toriel." She introduced.
"My name is y/n. I remember falling down a hole and that flower..." You signed, looking back.
"Ah, well once we get to my place, I will tell you about this place."
You both walked and you noticed many puzzles tested you. You had to solve them in order to get by. You had to admit, it was pretty nice down here, but you had to get back home.
She took you inside and you noticed that it was a pretty average house. You looked around. She gave you a room, but it seemed to be for children. Maybe she had a child, but something happened?
"You are in a place where monsters had been forced to live. Both monsters and human have lived peacefully until the humans had put a spell to keep us down here and well, we have been trapped," she sighed sadly. You felt pretty bad, considering that you were a human.
"I see, so it's the humans' fault?" You asked.
"Well, possibly. You should get some sleep. It's pretty late," Toriel offered. You nodded. Maybe you can get home tomorrow. After all, no one's going to miss you. You had no family, just friends. Yet, you didn't know if you could trust them.
You dressed into pjs and laid down in bed. You could here a knock. You quietly listened, curiously.
"Frisk, back so soon?" Toriel asked.
"Yes," she answered.
"I'm afraid your room is taken by another human, but maybe you can sleep with me."
"I didn't come here to sleep. Papyrus wanted you."
Papyrus???? This jumbled up your thoughts. You heard footsteps walk to your door. You pretended to sleep and you were shaken. You pretend to open your eyes sleepily.
"We'll take a rest at the Snowed inn." You nodded as you changed again to your clothes. She had a suitcase. She said that she got some clothes for you. You nodded and you both headed off to your journey.
