The ponies backed up in fear when the thing spoke, and Twilight couldn't help but notice that it was with a noticeable Trottingham accent.
Behind the creature that spoke, the others started moving in various directions, though still remaining in a group. Notably, two of them looked to have swapped out their black objects for medium-sized knives. Soon, they reached the group of ponies, and, defying all logic and reason, passed right through them. Several dumbfounded looks later, Applejack was the first to say something.
"...What the hay just happened?"
"It seems that they aren't physical beings... or something..." Twilight tried to come up with a reason for what just happened, but was drawing a blank. Nothing she had encountered before came close to the confusion this situation brought, and she had seen firsthoof what Discord could do!
It was then that something else was noticed by the ponies. "Do you hear that?" Rainbow asked, looking for the source of the noise.
The noise in question was a sort of growling, mixed with the occasional sound of rasping. The ponies searched for where it was coming from, and found it not too far from where the six things had gone. Coming down the road towards them was a group of even stranger things. These creatures lacked any clothing, from the look of it, and their claws and mouths were covered in dried blood. Amidst the dozen or so of those gray things, were slightly larger, blood red ones. The red ones had a blade seemingly stuck straight into the stump of an arm, and their lower jaws looked to be missing.
Once the six not-horrifying things caught sight of the horrifying ones, one of them tossed a small rock-sized object into the middle of the group. After a couple of seconds, an explosion erupted from it, sending the monstrosities and their limbs flying. Immediately, the others started using their devices at the stragglers, causing much smaller explosions that caused the creatures heads to literally pop.
The ponies were nauseated by the scene of bloody carnage, to varying degrees. Unsurprisingly, Fluttershy fainted.
"Just what in the world is going on?!" Rarity shouted over the gunshots.
"I don't know!" Twilight had to think fast. Thankfully, for whatever reason, most of the exploded monster things (which could probably be referred to as zombies, she realized) had disappeared when they weren't looking, and all that was left was blood stains and a scorch mark on the ground.
More of the "zombies" appeared out of seemingly nowhere and started advancing towards the six creatures, who were successfully staying alive amidst the onslaught. The two with knives were cleanly decapitating the smaller zeds with a single swing, though one of them was doing so at a much faster rate.
One from the middle of the group spoke again. "You're all fur coat, no knickers, bitches!" While the ponies, Rarity particularly, gawked at the foul language, the thing threw another small device.
Twilight ignored it in favor of getting things done. "Rainbow Dash, I need you to-"
Suddenly, as another explosion was set off, time began to slow down significantly, throwing Twilight off her words. After a couple of "seconds", time returned to normal with an audible "fast forward" noise being heard out of nowhere. The six fighting creatures seemed completely unaffected by it.
"Time manipulation, too?!" Twilight shouted, exasperated. "Quick, Rainbow, before anything else crazy happens, get everypony in town assembled in front of town hall!"
"On it!" The pegasus flew off, leaving the other four (plus an unconscious Fluttershy) to begin walking to the center of town. They nervously passed a few of the zeds on their way, but the monstrosities didn't seem to notice them, and like the six things that were slowly tracing the ponies' path, they even passed right through them.
After fighting to keep their stomachs down after getting a rather close look at how the red ones had the blade not on a stump of an arm, but spliced straight into an arm, splitting it in half, they arrived at the center of town. Rainbow had worked quickly, as almost everypony in town was there. Twilight noticed that there was one of the metal doors on the town hall, as well.
Making their way to the front of the crowd, Twilight placed a voice amplification spell on herself, and began speaking to silence the murmuring crowd. "Everypony, settle down. For reasons I have yet to know, it seems that many different strange creatures are appearing throughout the town. Six of them look to be warriors of some kind, while the rest seem to be, for lack of a better description, monsters." This got the crowd talking again, which was silenced by a raised purple hoof. "While the proceeding fight has been.... grotesque, it seems that none of the creatures will harm us, and I believe they actually can't, for unknown reasons. Despite this, the six I mentioned before seem to be able to see us, though I don't believe they have any significant feelings towards us, hostile or otherwise."
The crowd began talking amongst itself, and soon a single stallion near the back shouted, "Well what should we do?"
"That is an excellent question. I feel that, for the time being, seeing as how they can't harm us, we simply wait it out. We've been through tougher things, after all."
Once her speech was finished, Twilight walked over to her waiting friends, who had impressed looks on their faces. "I didn't know you could give speeches like that, egghead," Rainbow commented.
Twilight blushed. "Well, I just tried to channel Celestia, is all."
At this point, the six creatures had all but arrived in the town square, the monsters following them. The flow looked to be slowing down, though a couple of the six received wounds from the red zeds. Despite this, they simply kept fighting, and soon a single creature remained.
The whole time, the crowd was predictably panicking, but after Twilight urged them to calm down, and they saw for themselves that they couldn't be hurt by either party, they settled down a bit, though the panic was quickly giving way to nausea and disgust.
One of the creatures fired a single shot, popping the monster's head like a grape. But contrary to common sense, it kept walking forward a bit more, albeit not in anything resembling a straight line, and soon it bled out and fell. All at once, the six creatures all pulled out knives and started running through the crowd. Several screams ring out, but slowly die down as they pass right through them, not dissimilar to ghosts. Turning, they saw that not only was the metal door on the town hall now open, the six were entering the building in what looked like a hurry. Once inside, they simply stopped moving and stood in place.
Curiosity and confusion overtaking her, Twilight followed the things inside, finding the town hall in the same shape as it had always been, save for a single new addition. A wall near the back had been covered in a counter with a fence on top, and behind it stood another thing like the six, though this one had its face uncovered, and looked to be feminine as a result.
Out of the corner of her eye, Twilight noticed that the creatures now were holding all manner of unknown devices (save for one, who was holding a fire axe), nearly all of which were different shapes and sizes. One of the creatures, the "curvy" one, began looking around.
"I need dosh. Anyone?"
Like the other voices she heard from them, this one had a Trottingham accent, though unlike the others, this one sounded female. The other five began moving about, and two of them faced the one who asked for "dosh". Out of nowhere, bright green blocks of... something began flying out of them, and was seemingly "absorbed" by the beggar.
"Money, money money!"
"Dosh! Grab it while it's hot!"
Twilight had no idea what any of the phrases meant, but judging by the money comment, this was their currency. A zipping sound could be heard from the female one, though her appearance didn't change.
"Cheers." The six of them then began walking back outside while injecting themselves or each other with some sort of small red device. Outside, almost everypony else had seen what happened. As they left, Twilight was about to look at the seventh creature some more, but suddenly she found that she was back outside, inspecting a wall. She jumped back and let out a small yelp, and looked around to see the other ponies looking at her worriedly, and the door to the town hall now closed.
Twilight let out a groan and hit her head on the wall. "WHY DOES NOTHING MAKE SENSE IN THIS TOWN?!"
In the distance, one of the creatures remarked, "Wayne Rooney's smarter than you!"
