Chapter 1: The discover

This all starts when Papyrus 'convinced' Undyne to let him do 'patrols'. By convincing we mean barging through her door at 3 AM and by patrol we mean that Undyne sent him into a random zone of the underground.

"Wowie! My first patrol! In no time Undyne will have to accept me as a member of the Royal- AHHHH!"

Papyrus had the bad luck to step on hollow ground. He fell, and fell, and fell...

Then he landed with a loud thud on a metallic floor.

"OW! What-!?" He looked around. Absolutely no light entered that forgotten corner of the underground.

"I-I better call Sans about this!" He quickly pulled out his phone and called Sans.

His brother answered almost immediately. "Bro? What do you need? I thought you were on patrol-"

"EXACTLY!" Papyrus quickly interrupted. "I fell off somewhere dark and I don't know exactly where!"

"What? Don't worry, I'm coming immediately!"

"Sans, wa-" Papyrus was knocked out by a falling panel before being able to finish the phrase.

"Pap? Papyrus, you still there, right!? Bro!?"

"I'm sorry" a female synthesized voice replied. "But he cannot answer you..."

"What!? Pap, what's going on there? WHERE ARE YOU!?"

But this time, the only answer was sheer silence...

A lil' note! An OC shall be incorporated in this story, so don't get used to familiar faces!
