"Ugh..." Frisk said, she didn't remember much of anything... just that she fell.
"Where am I?" She thought out loud. She looked around, she appeared to be in some sort of abandoned civilization underground. She landed on a patch of fallen leaves. Looking up, she saw an orange sky, the tree's leaves above were changing colors, indicating it's ironically fall. Frisk wanted to laugh, but was in too much pain. Sense the pain wouldn't ease up, she decided to stay a while and take a nap, maybe it would help.
Too bad she couldn't fall asleep, so she got up anyways. She walked down a path, and turned into a doorway leading to a descent-sized room. In this room there were two staircases leading up to another doorway, between there was a bed of golden flowers, and a... boy... tending to them.
"Help, please..." Frisk pleaded to the boy, who quickly turned around and went wide-eyed at the sight of the injured human. It was at this point frisk passed out from the pain and exhaustion.
"Agh... my head..." Frisk woke up in a strange place... They were in a bed... looking around everything seemed rather dull and gray. They turned their head to the side and saw a dusty picture... in the picture was the boy from before... although looking at it now he kinda looked like a bipedal goat-looking creature, and next to him was a girl, whom surprisingly looked a lot like themselves. Other than her headache, she realized most of her pain had faded away, along with any bruises.
Since she had the time, she once again tried to remember how she got here, suddenly pictures started flashing through her head, one of two skeletal brothers, another of a family of three goat-creatures, a third appeared, blurry and distant, but there. She saw a child, much like herself, although her face wasn't visible, but it was obvious she was sad. Frisk had to stop at this moment, her headache suddenly got much worse.
She noticed some stuff on the floor by the bed, it was a purple scarf and a cup of coffee. By the stuff was a note that read "Sorry I can't help you out any further... Chara would probably be mad if I did, although I can give you this scarf, it's gonna get cold real quick. I do know somebody who might be willing to help you. He's a skeleton in Snowdin named Sans, he might be hesitant at first though. -Asriel"
"Is this that goat kid?" Frisk thought out loud. She got up and grabbed the purple scarf and put it on, then took the cup of coffee and chugged it rather quickly, it having been cold from sitting there for a while. She left the room and immediately noticed something. The entire house was a bland gray color except for the basement staircase, which was a dark shade of purple. She decided there probably wasn't anything worth while lying around, so she left the house. Immediately she got a sense of deja vu, and her instincts told her to go back in and go through the basement, so she did.
As soon as she got into the basement she felt a cold breeze. 'Thankfully i got this scarf' she thought. The basement wasn't much, just a long hallway, and at the end there was a door. She opened the door with little hesitation, although on the other side there was snow... a lot of snow. Thankfully it wasn't snowing, that'd be an issue. She continued on, and after a while ran into a bridge. There wasn't anything special about this bridge, it just made a path over a small gab between her and the next area of land, she just felt like she shouldn't cross it, so she stood there.
She didn't know how long she stood there waiting, just looking around before something happened. "Hey, if I were you, I'd get moving, you never know when you'd run out of time." A voice said behind her. She quickly spun around to see who said it, but nobody was there, so she crossed the bridge and moved along rather quickly. She felt intimidated the way he said 'you never know when you'd run out of time' just scared her.
She kept moving on, it was eerily silent. After a few minutes of walking through the snow, she started to hear something, it was quiet, it sounded like people talking, laughing, and having fun. She followed the noise, and not after long she ran into another bridge, this one much longer than the other. On the other side she saw a couple figures standing there, although she couldn't quite make out who they were. She crossed the bridge to the point where she could hear and see them, they were two skeletons, one short, rather chubby, and wearing a blue hoodie, black shorts and pink slippers. The other was sitting down, but seemed rather tall and wore an orange turtle neck, black pants and orange shoes.
"papyrus, it's time for us to go, you've been sitting here for hours, why?" the standing skeleton said. "BECAUSE SANS, I HAVE A FEELING THAT I WILL MAKE A FRIEND HERE. I MAY SOUND CRAZY BUT I WANT TO STAY HERE UNTIL I MAKE A FRIEND" the sitting skeleton said, he seemed energetic.
"Hey, do either of you know where Snowdin is?" Frisk asked, catching the two skeletons off-guard. They stared at her in shock before the short one called Sans asked "Kid... are you a human?"
