Twilight Sparkle was busy in her library, going over more ancient books that had been given to her by Princess Celestia. Within their yellowed pages, she was finding more and more of the secret history that had been hidden from the populous for centuries after the Shadow Wars ended. Her eyes were locked to every word, her magic inscribing details and relevant information on scroll after scroll. Her mind was racing at breakneck speeds as she tried to fathom all that could be learned from this forgotten record of how Equestria came to be what it was today.

So engrossed was she, that at first she didn't notice the voice calling out her name. Yet upon the third utterance, she was finally dragged back into the real world as she turned to look over her shoulder.

"Yes?" She asked, "Can I help you?"

Twilight's expression shifted from a friendly smile to a confused frown when she found the room behind her empty of anypony. Yet she knew she had heard a voice calling her name for the past few minutes.

"Down here Ms. Sparkle." A vaguely familiar voice called out from below her chair.

Twilight looked down and yelped in shock as her wings flared wide. Resting under her chair, was none other than Discord, although the calm expression on the chaotic being's face was highly unusual, given his pention for enjoying a good prank scare.

"Discord?!" Twilight yelled as she hopped off the chair and turned to face the draconequus, "What are you doing here?"

The limp Lord of Chaos raised his head off the ground a few inches, a miffed expression on his long muzzle as he replied, "Firstly, I would kindly ask you to refrain from comparing me to that overblown buffoon. My name, as given to me by Princess Luna, is Carpet Sense, and as for why I am here, I am a carpet, it's what I do."

Twilight's eye twitched slightly as she stared at the apparent living carpet, "Carpet Sense, was it? Why are you in my castle, and what even are you?"

Carpet Sense rolled his eyes, "To answer your second question, I am the former body of Discord, given purpose by Princess Celestia to act as a carpet to the best of my ability. I am currently looking over the whole of Canterlot Castle, and have apparently moved into your castle as well. I do not know fully what it is that caused my sudden appearance in your home, but as a carpet it is my duty to cover the floors of any building I find myself in. Thus, I shall look out for your abode as well." He sighed in a way that made his body flutter like it was in a breeze, "As for why I am in your castle specifically, I already told you. I am a carpet, it"s what I do."

Twing!

A strand of Twilight's mane sprang out at an odd angle as a slightly frustrated look came over her features, "But, that's, you, AARRGG!"

She turned around and stormed from the room, choosing to remove herself from the presence of the aggravating yet undeniably logical piece of furniture. She marched into the hallway and made her way up to her bedroom, thinking that it might be best to get a quick nap in before she got back to reading.

Yet as she was opening the door to her personal chambers, she was assaulted by a very familiar voice from below, "Would you mind opening the door the other way? My tail is getting crimped from the door sliding over it."

Twilight looked down and screamed as she took to the air, her wings beating frantically as she tried to calm her racing heart, "Carpet Sense! What are you doing in the hall? I thought you were in the library?"

The animated carpet gave her a long-suffering look, "I think you ponies must have some form of brain damage, because I find I keep having to repeat myself to everyone I meet. I am a carpet, therefor I am meant to cover the floor inside of a building. It's what I do. How exactly is that hard to understand?"

Twing! Twang!

Twilight's mane and tail were starting to look rather frazzled as she took a deep breath and let it out in a slow movement, "Alright, fair enough. Just don't go looking through anything you shouldn't alright?" She landed and pushed the door open the other way, letting his tail uncurl as she stepped over him and into the chamber proper, "Now I'm going to get some sleep, and I'd better not hear anything coming from you or else I'm going to see how much magic I can hit you with before you tear."

Carpet Sense nodded, "I shall be here if you need me, although I don't think it will matter much."

"Why's that?" Twilight asked over her shoulder as she walked into the room, only to trip and fall on her face as her hoof caught against something that hadn't been there the last time she had been in the room.

Twilight's gaze was locked onto the wide and mismatched eyes of Carpet Sense as he lay upon her bedroom floor, "Because I will be in here as well if the need to talk should arise."

Twilight looked from the Carpet Sense on her bedroom floor, and then back through the open doorway to see another Carpet Sense resting out in the hallway. Two Carpet Senses, and if the one back in the library was still there, that meant he could end up in every room in the castle in no time at all!

Twing! Twang! Twing! Twing! Twang!

"AAAAAHHHHHHHH!" Twilight screamed, echoing through the halls as her mane and tail turned into rather good impressions of a bird's nest, her hooves carrying her down the halls as more and more Carpet Senses popped into being.

Twilight raced into the one location she knew would be safe, and locked the door behind her as she locked the magic seals that were normally used to keep her experiments contained. Now, she was doing everything she could think off to keep that living floor cover out of her hair.

Twilight stepped back from her lab's locked doors, taking a breath to try and calm her heart as she sighed in relief. Yet, something seemed off. The normally hard floor wasn't the same smooth tile she was used to. Instead it was soft and had a slight give to it as she pressed down with one hoof.

"Ooh, yes," the one voice she dreaded hearing cooed, "just a little to the left please."

Freezing in place, Twilight's eyes shrunk to pinpricks as she refused to look down, "No, it can't be. I have level ten containment spells protecting this room. There's no way he could have gotten in."

A gentle prodding against her fetlock made her close her eyes in the hopes that she was wrong, "Oh but I must be in here, after all, this is a room with nothing covering the floor. Therefore, I am needed to keep things orderly by doing my duty as a carpet. Why else would I be in here?"

Twilight's eyes opened as she sighed in defeat, "That's it. I give up." She glanced down at the calm carpet below her, her own expression one of complete resignation, "You can stay if you like, but please try and avoid scaring my friends by talking to them out of nowhere."

Carpet Sense held a claw to his chin as he pondered something, "You know, Princess Celestia told me roughly the same thing. I wonder why ponies seem to have trouble with carpets talking to them if they know I'm in the room. Where's the surprise in all that?"

Twilight let out a sigh as she unlocked the lab doors, making her way back to her room before climbed into bed. Once she pulled the covers over her body, she rolled over so she faced away from the new furniture, "Good night Carpet Sense. If you must, let me know when Swift Blade and Sarah return from their training."

"You do realize it's only midafternoon, right?" He replied.

Twilight levitated a pillow over her head and groaned. It was going to be a long time before she got used to her new house guest.

Author's Notes:

So now we get to see Carpet Sense drive two princesses up a wall!! Oh joy!

Anyways, hope you like the little break from the main story, given we haven't seen Carpet Sense for a while. I just love writing his lines because I can easily imagine the torment he causes others. It's just plain hilarious to see Twilight or Celestia losing their minds from the perfect logic of a carpet version of Discord.

Anyhoo, I hope you all enjoyed that little detour down crazy street, and I'll see you all next chapter,
Shadow Quill, Messenger of the Moon.
