(This happens after the Pacifist Ending in UTY!)

You had fallen into the Underground, and followed Toriel through the Ruins. When you both reached the levers, the left lever didn't work. Toriel told you to not do anything, and that she'd be back soon. She quickly ran into one of the previous rooms to do... whatever. You looked around for something to do, and eventually got a little bored. 10 minutes later, Toriel still wasn't back. You got curious and pulled the right lever. The ground beneath you gave way and you fell. You got up and wandered around the Dark Ruins. They didn't look very inhabited, maybe abandoned. You simply walked around until you found a place that looked like an abandoned home. There was dust everywhere, and you decided to rest there for a bit before moving on. After resting, you got up and continued on. You entered Snowdin, which was MUCH colder than the Ruins. It was very snowy... lives up to it's name. You walked around the snowy terrain and bumped into someone. Dalv: Oh! Sorry! I-... wait, are you a human?
