The darkness hung like a blanket over the realm of Equestria, the moon unleashed its beam of moonlight down upon the land below. Creatures were all sleeping comfortably.

Quiet, that was all it was. Nopony ever heard or even saw it, the only hint that it had been there was its shadow, stretching for miles and miles.

Ten years, that is how long it has been since the ending of the war between the Ponies of Equestria against the Emperor and his (assumed) never ending army.

After his destruction at the hoof of Princess Celestia and Twilight Sparkle. Equestria has endured a long peace. But recently a new evil has risen, Unicorns have been starting riots and shootouts in various cities across Equestria. Manehattan, Filly Delphia...even Las Pegasus have all fallen victims to these violent groups. Celestia has dispatched forces to these various cities in order to restore peace...but despite her best efforts she has still to discover the reason for such violent behavior in these recent days. The only clue she has to go on is that they are all Unicorns...but even that is a little bit odd, if mostly Unicorns were being affected...then wouldn't Twilight be affected as well?.

She paced back and forth, her mind thinking of nothing besides the violent uprisings.

''Twilight maybe you try and get some rest, thinking about renegades will just make you too exhausted to come up with a way on how to defeat it'' Spike suggested, Twilight stopped pacing...mostly because she had now created a large round circle in the middle of the library, she turned and looked towards Spike.

''Maybe your right...maybe I should go and rest'' Twilight replied, crawling out of the round hole in the center floor of the room. Noticing her handy work she hurried up to her bed before Spike could comment on it.

Suddenly the sound of a large crowd sounding from outside interrupted Twilight's nap, she gently rose up from her bed and approached the window. Out of her window she could see all manner of Ponies galloping towards the Everfree Forest. The door burst open and Spike ran in exhausted, panting heavily to himself.

''Twilight...you...have...to see...this'' he spoke, completely out of breath, he collapsed down on the floor exhausted, Twilight rolled her eyes and hurried out the door...but not before levitating Spike up into his basket(or whatever it is he sleeps in).

By the time she arrived at the Everfree Forest she found a huge crowd of Ponies all gathered around. She made her way through the crowd to find a small group of Celestia's golden guards overlooking something that was laying on the ground. One of the guards turned and noticed Twilight.

''Ah Mrs. Sparkle, the Princess said to allow you to take a look at it'' one of the guards said.

''Take a look at what?'' she asked, her gaze fell upon the object on the ground, and she gasped in horror as she saw it. Quickly turning her head away and covering her eyes. ''Why do you need me for something like this?'' she asked.

''Because you’re an acquaintance of the Princess...and when she found out...just like you did now, she immediately knew of none better to handle it'' the guard responded.

Suddenly without warning an Earth Pony strode past her, he approached the object on the ground...but froze in place immediately once he set eyes on it. An expression of disgust fell over his face.

''...ugh that’s disgusting'' he muttered to himself. Before he could move closer towards the object of disgust him the guard grabbed hold of him and forced him away from it.

''Excuse me but what are you doing sir?'' the guard asked him.

''I’m a medic, I’m tending to my patient...or at least what’s left of it'' he responded, the guard turned his head and looked towards the object...and then back towards the supposed medic.

''That...is nothing but a disgusting sight, now please tell me who you are'' the guard responded.

''I've already told you, I’m a medic'' he responded.

''No, no, no, you've told me your A medic, I want to know your real name'' the guard instructed.

''Oh...well I guess you can just call me The Medic'' he responded, Twilight gave a slight chuckle at his response, the guard only groaned to himself.

''Fine be difficult, but I called specifically for Twilight Sparkle...not some military medic'' the guard responded.

''Uh excuse me sir, but I think that it seems logical for him to be with us...he after all seems to have some interest in this case'' Twilight responded.

''Oh believe me Twilight, I am not interested in the case itself...my interest is purely to find out who or what is doing this'' the medic responded.

''Wait a minute, how is it that you have been here only a few minutes and your asking questions like that?'' she asked him, confused by how one could work so fast.

''Oh believe me, this isn't the first time I’ve witnessed such a case...all throughout this month I’ve finding decapitated corpses all across Equestria,

Manhattan, Filly Delphia, Baltimare, Apple Lossa, Las Pegasus, Vanhoover, Cloudsdale, Canterlot...and now finally here in Ponyville'' he responded, the eyes of the guard and Twilight widened in shock, to think that there had been so many grotesque murders all throughout Equestria...and yet not one of them reported or mentioned by anyone. ''So what is our course of action...Mrs. Sparkle'' the guard asked her, she looked towards him shocked, a long period of thought fell over her.

''Well firstly we need to get all these Ponies out of here, if just one of them finds out about that these murders are happening all around the world then one is all it takes to alert the rest of them'' Twilight instructed, the guard nodded in response.

''You two with me'' he said, pointing towards two of the royal guards stationed there. They approached the crowd of Ponies and began moving them away from the site.

''Twilight...'' the medic whispered into her ear.

''Yes...?'' she responded.

''I know now what did this...'' he said, her eyes widened.

''But you didn't even examine the body'' she replied.

''Your wrong, I looked into it while you were talking with the guard...and it as I feared''.

''What? What is it that frightens you?''.

''This Pony didn't die of decapitation, she was already dead by the time whatever it was that killed took her head...'' he answered.

''But how can a medic know that?'' she asked him.

''You see the blood...?'' he asked, she looked down towards the body. Closing her eyes at the sight of the dead body.

''Yes?'' she responded.

''She began bleeding when they cut off her head, but the bleeding happened recently...now if you look at the rest of the body it is clear that it is very much dead, so whoever or whatever it was that took her head wanted her alive'' he explained.

''Then why is her body dead and not her head as well?'' Twilight asked him.

''Because the weapon that was used to ''kill'' her would only affect her body...and not her head. However when they removed the head they didn't count on the heart still being alive, so when they decapitated her the blood continued to pump'' he explained further.

''That’s repulsive...'' Twilight commented.

''And to make matters worse...whoever or whatever did this is still here''.

''How can you possibly know whoever is still here? What is point? Why stay and get caught?'' Twilight questioned him, unable to believe his theory.

''Because whoever we're dealing with is not your normal murderer, they know the danger of leaving clues...so they leave one behind to make sure that no clues or progress on the case is made''.

''How do you know all this? You’re just a normal medic...no offense'' she responded.

''Oh Twilight...I am far from an ordinary medic'' he responded. ''You wanted proof that its still here…? Put on these glasses'' he said, he lowered his head and revealed a pair of glasses on the top of this head.

''Have those been there all this?'' she asked him.

''Yes, otherwise I wouldn't have been able to see the suspect we're looking for'' he replied. Closing her eyes, she levitated the glasses of the medic's head. Placing the glasses in front of her eyes, she opened her eyes and looked towards him, but now the world was completely red and blue.

''Look up towards the Everfree Forest, tell me if you spot something suspicious or out of the ordinary'' he instructed. She turned her gaze and looked towards the forest as he'd told her.

''I can't see...'' suddenly her eyes spotted something, hidden at the edge of the forest, it was moving back and forth. It suddenly turned towards her, their eyes connected, it didn't move or react...just watched.

''I can see it, its right where you said it would be'' she said. The creature intercepted her words to the regular Earth Pony.

''Commander I have been discovered, what is my course of action?'' the creature reported.

''Destroy them, there must be no witnesses'' a voice responded.

''It shall be done'' the creature responded.

She quickly removed the glasses and looked towards the medic.

''Now what do we do?'' she asked him.

''Well judging by how long you were looking i would say that it now knows that you know about it...''.

''And what does that mean?'' she asked him.

''Death...'' he said, a tone of dread in his voice.

''No witnesses...'' she whispered to herself. She quickly turned towards the guards.

''OUR MURDERER, HE IS THERE'' she shouted, pointing towards the edge of the woods where she had seen the creature. The guards quickly turned around and faced where she was pointing. The Unicorns in the group unloaded powerful bursts of magic towards the pointed out location. The area exploded as the magical bursts hit.

''What have you done?'' the medic asked her.

''We destroyed it, before it destroyed us'' she responded.

''You've not destroyed it, that’s nothing compared to its firepower...and now it knows for sure that its been spotted, you must get these guards out of here'' he said, he quickly swiped the glasses off her eyes and placed them on his own, he galloped quickly away from her to the small backpack he'd brought along with him. He began galloping up towards the edge of the forest.

''TWILIGHT...LOOK'' one the guards responded, she turned to where the guard was pointing. The creature was covered in electrical surges and sparks.

''It was invisible'' she whispered to herself. The creature's glitching stopped and its full form was revealed. Its left arm pointed towards one of the guards, a beam of blue energy shot out from the arm.

''AHHHHH'' he screamed as the beam of energy hit, his body was engulfed in a powerful blue glow...before falling down dead on the ground.

The Unicorn guards attempted to return fire towards the creature, but Twilight remembered what the medic had said, their power would be useless against it.

''RETREAT, GO, GET OUT OF HERE'' she shouted to the guards, ''NOTHING WE DO CAN HARM IT, WE MUST LEAVE WHILE WE CAN'' she instructed to them. The Unicorns realized that she was telling the truth, even their most powerful spells seems to barely scratch it. The creature fired several more blue beams towards them, but with them trying to escape rather than fight it was more difficult to get a proper aim.

In its effort to destroy the Equestrians the creature was completely oblivious of a small brick. The brick landed beside the creature, the smoke from its fuzz finally caught its attention.

''Emergency tempora-'' but before it could finish its sentence the block detonated, the creature was engulfed in a fiery explosion, bits and pieces of its armor flying down towards Twilight and the few guards that remained at the site.

As the smoke Twilight approached the explosion site, using her magic she moved away the smoke...in the thicket of the forest she could see a dark silueted figure galloping away, in need of answers she took up pursuit after the silhueted figure...into the Everfree Forest.
