SCP: Containment Breach & My Little Pony: Friendship is Magic Crossover

Chapter 5: The Corner of Your Eye...

The six mares walked away from the small testing chamber where the sculpture has claimed its new territory. They found themselves in another empty hallway. Rarity had decided to lead the way when they reached the end of the empty corridor. She led them through a four door corridor and picked the door on the left. The left door led them to another empty corridor, much to their dismay.

The six mares walked through the empty hallway and Rarity spotted something in the distance through the open door at the end of the hallway. It was a large blast door that looked like an exit out of the facility. Rarity had gotten her hopes up.

"Look!" she cried, "An exit out of here!"

Her friends exchanged optimistic expressions as they tried to run out of the hallway. But the door closed on its own, making a high pitch hissing noise. Rarity backed away as her muzzle was almost crushed in between the sliding doors. She was most frustrated.

"Why does every door in this place happen close in on our muzzles every time we get near one?"

"Why don't you keep your muzzle out of stray doors?" joked Rainbow.

Rarity grumbled at the cyan pegasus' joke as she pressed the button to open the door back up to see the large blast doors again. The six mares walked into the room with the large blast doors. But instead of it being an exit out of the facility, the large blast door was an entrance of an enclosure for another anomaly. On their left was a hallway leading away from the containment chamber while a label for the anomaly was on the right wall. The six mares looked at the label.

SCP-372
OBJECT CLASS: EUCLID

The label had what appeared to be a black and white picture taken in a corner in a room with a blurry glimpse of an unknown entity sticking out of the picture in the bottom left corner. Before either of them wanted to enter the containment chamber, they walked into the hallway beside the entrance with the hallway. Pipes had been installed and were exposed through the walls with some pipes connected from the floor to the roof. The hallway made them make a right and was met with a sign on the wall on the right and a door with a red button on the left. The sign gave directions with pointing arrows such as SCP-372's containment chamber on the right and the maintenance room was on the left at the end of the hallway.

Rainbow Dash pressed the button to the door on the left to see what was on the other side. The door opened and found there was another four door intersection on the other side. Rainbow Dash closed the door by pressing the button again with the dark corridor giving the impression of being anything but safe. The six mares continued their way through the hallway and turned another right. They found the end of the hallway with two closed doors.

One door in front of them had a sign above it reading, 'MAINTENANCE ROOM 4D' and a slot for a keycard. The second door was the same as the one Rainbow had seen. Twilight used her magic to pull out the level 2 keycard from her saddlebag and inserted the keycard into the slot. As she swiped the keycard into the slot, she found nothing happened as the door didn't open. Fluttershy walked over to the second door and pressed the red button to open it.

The door opened and Fluttershy found an empty hallway with a dead corpse of a Class D lying on the ground near the door. The yellow pegasus stared at the Class D in horror as Applejack poked her head out to see what was behind the second door and gasped at what Fluttershy saw. She and Fluttershy thought it was a good idea to close the door.

"I think we should see what's inside the containment chamber," suggested Rarity, "what do you girls think?"

"Anything is better as long as we don't stay here," answered Fluttershy.

The six mares turned back the way they came and Rarity inserted the keycard into the slot, opening the big chamber doors. Behind the chamber doors was the control room. The six mares stepped into the room and searched for anything useful.
