You had fallen into the Underground, where monsters had been sealed like... around 1000 years ago? You don't really know. What you do know is that it's really dusty. You had been wandering around the Ruins and found some sort of house. There were a lot of books, one of which caught your interest. "MONSTER ANATOMY". You grabbed the book off the shelf and started reading, there was a section on how monsters bodies were made up of mostly magic. It was fine till you saw a page about how when monsters die their bodies turn into dust... guess that explains the dust everywhere. You took the book with you, just in case you needed it, and went to the basement area of the house. There was a pile of dust in front of the doorway out, so you walked around it and exited the Ruins through the door. After exiting the house and Ruins, you were in a snowy forest area (Snowdin), and it almost made you forget you were trapped underground underneath Mt. Ebott. You made it to some sort of town, although it looked pretty abandoned. There was a sign saying "WELCOME TO SNOWDIN TOWN!" There was a shop, that looked pretty ransacked. You walked past the town, there was a notable house, it had a lot of christmas lights, and there were two mailboxes outside of the house. One said "Papyrus" and was empty, while the other one said "sans" and it was overflowing. You walked to a foggy area and saw a human standing infront of a tall skeleton, probably a monster. You saw the human slash the monsters head off and walk away to Waterfall while the monster turned to dust. You were about to run after the human, probably to stop them or something, when you noticed a shorter skeleton standing behind you. "who are you?"
