Silence. What was behind her? she thought.
Did she dare to look around?
Hesitantly, she craned her neck backwards.
And she saw-
Nothing.
At all.
"T-there's nothing."
"Yes there is."
"Well, what do you see?"
"Like this guy said. Has a round, smooth head. Too many eyes. Looks like a really badly botched plastic surgery job."
"Right. Can you...talk to it?"
"Uh, I'll do it." D-1325 said.
D-1325 walked over to where he saw the entity last.
"Hey. Weird thing. What's up with your face?"
Suddenly D-1325 jumped back, almost tripping over his own hooves. Then...
Something impossible.
Cuts started appearing on the colts body, as if he was being stabbed with something incredibly sharp. He screamed and squirmed, until he stopped moving completely.
D-7096, who still had the glasses on, saw the whole thing. She ran to the door, and attempted to break it down. She looked behind her.
"NO!" she screamed, "GET AWAY!"
As soon as she got cuts on her, Twilight immediately opened the door. D-7096 limped out with multiple cuts on her left leg.
"God." she said. She was immediately apprehended by a guard.
Twilight walked out. While still pointing the gun at her, the guard asked her, "Dr. Sparkle, do you know this D-Class?"
"Yes. Can you take her to the medical ward?"
"Yes ma'am." The guard responded.
Twilight walked back into the chamber. "What was that?" Twilight asked Cadance, who was finishing up the notes.
"Strange entities can only be seen with the glasses on. If you interact with them in any way, they'll attack you. But we can't see them at all." Cadance said matter-of-factly.
"Uh huh. I'm gonna see this for myself." Twilight opened the door to the chamber.
"Twilight, WAIT!" Cadance called. But she was already in the chamber.
Twilight walked to D-1325's corpse. Poor colt never saw it coming. He adjusted his head to see if there were any marks on his face. There was one small cut, that was already there, but that wasn't important.
She carefully took off the glasses, and felt them. Normal specs, she thought.
She slowly put them on. The glow of the red and blue of the old fashioned glasses completely filled her view. She looked behind her to see that hideous entity.
It was repulsive. Like both Class-D's described it, it had "too many eyes" and a "smooth head".
It gave off a strange effect. As if it was lunging towards her and quickly lunging back.
Cadance entered the room. She ran up to Twilight-practically through the entity-and grabbed the glasses and threw them to the wall.
"Are you alright!? God, who knows what happened to you! Don't do that again!" Cadance said frantically.
"I'm alright. I saw it." Twilight told her sister-in-law.
"The entity?" Cadance asked.
"Yes. It looked exactly like they described. Too many eyes, smooth head. You name it."
"...Okay. I'll send D-1325 to the Foundation morgue. You, you just take a break."
"Got it. I need a break from all this interesting stuff."
"Good. Just...just take it easy, okay?"
"Sure."
