First Nightmare Over Equestria

Turquoises had the shovel strapped to his back as he journeyed into the abandoned mine. The first thing he noticed when he entered the cave was that it was incredibly stuffy. His nostrils were immediately filled with snot when the warm, moist air hit his face. He was not the one for wiping his snout, but he didn't bring any towels to wipe his nose with, so he had to bear with it for now. For the most part, the cave was illuminated by lanterns still burning thanks to magic left behind by the previous miners. But it was strange that the cave wasn't boarded up. Maybe the previous owners thought they may return to it if a settlement built closer. With himself deep in thought, he ended up walking face first into a wall. "Dammit!" he yelled, but they his eyes were greeted by the most glorious thing he's seen all day, jewels. His face lit up with enthusiasm, as he sent the shovel he had in his hooves into the soft wall in front of him. It cause a bit of dirt to fly into his face, but it met with result as a few gems fell out of the wall. He laughed in rejoice as he threw a few into his bag, and he moved further into the cave. He saw the path ahead was dark, so he grabbed a lantern and went deeper.

****************
The secretary leafed through the paperwork that was laid on her desk. "Oh my." she said as one sheet of paper was brought before her.
To the order of the village,

I'm incredibly sorry for not having this filed earlier, but my father completely forgot to file this paperwork after the mine that we used to own was left behind. There was a good reason for this, but this has been left unsaid by my father, because of "business secrets". But I wrote this letter in this place because the deed to the mine has been left to me, and I wish the mine to condemned. Apparently, it was abandoned due to trouble with the structure, and was declared unsafe and unfitting by the miners to continue digging. Apparently a fault line was discovered in the cave, and tremors became common afterwards. Attached to this letter is a deed to the mine, and I urge you to send workers to board up the mine, before someone wanders in there. Please be as diligent as possible.
Current Owner,

Little D. Cryogene
The secretary leaped out of the chair, and galloped towards the mayor's office, shouting "Emergency! Emergency! We need to send a crew right now!"

Turquoise felt the bag become heavier as the bag became filled with more gems. Wiping the sweat off his nostrils, he exclaimed, "This place is completely filled with gems! Why would people abandoned this mine?" He decide it was about time to head back, and journeyed a little farther to gather a few more gems. "Mercy!" He shouted as he found a big green and purple gem embedded into the ground.
He hoofed at the ground around the crystal, and measured it to be around 2 feet long, 1 and a third in diameter. He shoved the spade under the egg shaped crystal and plucked the stone out of the ground. As he picked it up with his hooves, he discovered an attractable warmness to the object, He held it close to his face, and found an extreme attraction to it.
Not like, a beauty attractive, but more of a kin attraction.
Then it shook. He quickly dropped it, and it hit the ground with a *splat!* What he saw next will be unforgettable. A small black creature laid still on the ground, it's body about the size of a rabbit. Turquoise, who was always curious with things, got close to it. The warm air emanating from his snout hit the creature, and one of it's eyes opened. It was light blue, and didn't have a pupil. But even without a pupil, he could see it was staring at him.
It started screaming. It's shrieks filled the entirety of the cave, causing loose dirt to fall from the ceiling. Then he heard rumbling behind him. He turned to see a dark mass filling the cave around him. They all were interrogating him, all of them spiteful and horrid.
Who the hell are you? What are you? Why the fuck have you come here? Why have you disturbed our hatchery? What gives you the right to murder our young? ARE YOU PREPARED TO DIE!? Then the entirety of the cave shook, and dirt filled the space around him. His eyes were teared up from all the dirt, and it took him a few seconds to regain his sight. He looked around him, and found that there were holes in all directions, all with blue eyes. Then they all jumped, and his world went black.
