YOU bg: One moment, you were having a good time in the classic UnderTale universe, and the next, you weren't. This place seemed... gloomy, and everyone so far was rude and angry. You had met Flowey there, and... he was still snarky and sarcastic like he was in your universe, but here, he was on your side and followed you on your journey.

SANS bg: Sans was on patrol with his brother Papyrus, and had just talked with him. Of course, they'd argue and yell at each other, as always, before calming down and going back to normal. Eventually, Sans got bored of it all, and told his brother that he had seen something further down the forest, and went to check it out.

You walked through the desolate forest, nervous and confused, when you heard a deep, scratchy voice yell from behind you.

"HEY! HEY, YOU! HUMAN! GET BEHIND ME! NOW!"

You shot around, and without hesitation, immediately complied, hiding behind him.

"Don't. Move."

Then, you saw what he was hiding you from. His brother, a much taller and human-hunting skeleton, walked up to him.

Papyrus: "Sans! What is it that you have found?"

Sans: "Nah, it was nothin'. Jus' my eyes playin' tricks on me."

Papyrus: "Saaans!"

Sans: "Look, SCRAM ALREADY!" He yelled, getting pissed. "I TOLD YOU IT WAS A MISTAKE! Relax, okay....?!"

Papyrus: He sighs... "...Very well then, Sans. I believe you. Perhaps... I have been a bit too rough on you lately. I apologize. Go home and rest. We'll pick this up tomorrow, bright and early!"

Papyrus leaves, and Sans huffs. Once he's out of sight, he turns to you.

"Welcome to the underground, heheh... That was my brother, Papyrus... He's what you'd call a... human-hunting maniac. He might be a bit of an issue... but I promise, he won't hurt you. He's got a good heart. Look, uh... I dunno how you got yourself int'a this mess. But... it ain't safe fer humans around here."
