Hello, Hello! This story will be focusing on my oc: Bolide Hex! (Please do not steal!!!!!)
There will be characters from the show of course, but the main focus isnt on them. This is my first time doing something like this but im completly okay with critisism both negative and positive! (Keep in mind that my native language is not english though!) I hope yall like this, and have fun! 
The beginning of it all
Bolide Hexes hooves were clacking against the hard path of Canterlot's wide roads. As always he was making his way towards the library, to research for his essay thats due tomorrow. He was always a procrasinator, and yet he somehow manages to be one of the top students. Though their proffesor does give them an earfull when they turn in work late or right before the deadline.
After they entered the building, they peeked around quickly, looking for the biology section. They needed to write an essay about a ponies immune sytsem, and how it reacts to bacteria and viruses that enter the body. He didnt really like these kinds of topics, he already knew the basics of it, and he didnt join Queen Celestia's school for biology. Their cutie mark was about magic for pony's sake! However it needed to be done nevertheless.
They searched through the shelves, swiftly finding what they were looking for. The unicorns horn lit up with a vibrant green color, the magic grappling the book titled: Pony biology experted by Nimble Gust. Their long legs making the way towards an empty desk, sitting down on the chair. He sighed and opened the book grabbing a scroll and quill starting to take notes as he reads. Though their peaceful studying has been met with whispers of other poines who seemed to forget the primary rule of a library: stay queit so others can focus on read or/and learning. Yet just as he was about to scold the two ponies, sitting at the next desk, their conversations caught his attention:
"Oh Celestia! Thats terrible news... i hope he gets better soon, that poor fool, Sugar Hoof. What did the doctors say?" Asked the mustard yellow coated unicorn, fidgeting with her amber tinted mane.
"they dont know a thing about this 'new sickness'. They insisted that Sugar hoof should stay in the ponyville hospital, until they figured out what this illnes, really is!" Explained the purple pegasus who wash shaking her head with a scowl.
Hex was intruged, he had some relatives and even friends in ponyville, but he was sure if it was really anything serious, Princess Twilight Sparkle will take care of it. Though maybe he should write a letter to Thunder Wing, whos currently staying in Ponyville.
After he managed to finally finish his essay, he put the books back he teleported to the desk unconsciously, while being focused on taking notes, and feeling like there was too little information in just one book. They put the essay in a folder and carfefully put it in their saddle bag. They grabbed a scroll and quill again and started writing the letter as they walked to the post office, making sure to ask about Thunder's knowlege about the sickness, and to ask around if he can and has time. Though considering the bat pony was training forthe trails of getting in the wonderbolt, he would be quiet busy...
The letter was finished just as Hex set a hoof in the post office, there a mailpony carefully orginazing different kinds of packages, scrolls, envelopes and greeting card alike. The pale red, tall unicorn with a expressionless face approached the counter levitating the letter, neatly wrapped up with a ribbon, to the wooden furniture.
"Good evening, i would like this letter to be sent to Ponyville, to Thunder Wing, at - i belive - the oak library," Hex stated, hoping to get this mailing done fast and cheap.
"Good evening to you too! I am sure that this letter will get there, by tomorrow morning by our trusty mailponies. It will only be 4 gold bits!" Responded the earth pony with a smile awaiting the tall ponies anwser, hoping it would be paying (and not arguing about the price like some ponies do) and maybe getting a tip too.
The Red maned pony just gave a glare, and with a huff, payed the full price. They turned, and left the post office, heading to their home to rest and hopefully avoid their proffesor while they put their essay in the collecting box. Bolide gladly climbs into the bed, putting their grey scarf and dark brown gown on the hanger with a swift and simple levation spell.
The next morning came way too fast for Hexes liking. The unicorn groaned at the suns ray's attacking his eyelids. He got up and quickly gave his mane and tail a speedy brush, while also commanding the scarf on his neck, after the brown gown had already warmed his fur covered body.
He made his way towards the school, entering the esthablisment with a grumpy, yet not unusual expression. His peers did not gave him the nickname "mr.Grumpy-Horse" for nothing. His magic swiftly opened the door of the classroom, and he sat down at his usual spot, - after he actually remembered to turn in his assigment - which was in the middle row right besides a window.
It wasnt long before classes started and he was by then, deeply focused on anything and everything that came out of the teachers mouth. Preforming and explaining spells one by one. The details, the process of learning it, the process of preforming it, and the causes of it; and the side effects it had if it was an unperfected spell.
Sooner than the pony could process, classes were already over. They put away all their notebooks, quills, and books ready to head home and study for the rest of the day and even 'till midnight. But when they made their way outside in the somewhat clouded city, their gaze was avarted towards royal guards blowings horns for everyponies attention.
"Everpony of Canterlot! Listen here, we have a incredibly important announcment for all mares, foals and gentlecoalts alike!" One guard shouted at the middle of the road before continuing. "Queen Celestia and Queen Luna had decided to over go the city, in a moon long quarantine!"
Ponies all across the road gasped in shock, and confusion. Whispers and muttering of disbelief began to start like a disease. Bolide Hex was, too shocked. A quarantine? Let along a year long? Thats definetly not something that is normal. Thankfully, somepony was thinking the same way he was.
"Why exactly are we put in quarantine? Did we get another theath?" The bold pegasus asked, waving a hoof as he flapped his wings to get above the crowd.
"Fear not! The closing of Canterlot is not due to a monster or villian attack, its reason is a illness. It is completly safe and harmless. All it does is cause great discomfort, so her Majesty's want for comfort of the ponies here, they cautiously made this choice." The pegasus guard answered before, the two of them flown of. Probably not wanting to answer more questions - or not being allowed to.
This was defeinetly more than just a "uncomfortable disease". If it was, the doctors would have already found a cure and/or medicien against it. And this is whole situation was surley connected to that new illnes others ponies are talking about again, right besides him.
"I need to get to Thunder immidietly. i need bits for the train though, and if i dont get back before lock down - which i doubt i will - , i need to pack a few things for my stay at Ponyville!" Hex brainstormed under their breath, already galloping back to their home, burtsing the door open, and magically teleporting every essential thing while grabbing their saddle bag with a hoof.
They put away quills, a book or two, food for today, 100 gold bits, 5 scrolls and for the last a mask. He forgot he ebven had this, but at this moment it seemed almost necessary to take. He put the saddle bag on and before he could rush out the door for the train station - where the last trains were probably deporting right now - he heard a knck on his door and a soft voice "Mailpony here!". Thunder Wing probably replied!
They took the scroll from the mailpony without a word and teleported a golden bit into their hoof, where the was a second ago. The pony blinked twice and couldnt even comprehend what happened fro a minute before realising, The pony he deliverd a letter to was already galloping away.
Hex was greatful for his long legs at this moment, like anyother time he needed to rush somewhere. He made it to the train station seeing the train about to depart, he rushed to the ticket pony and three gold bits before basically shouting at the pony across the counter.
"A ticket to Ponyville!" Hex screeched as his eyes darted between the train and the pony quickly giving him a ticket while taking the money.
Bolide's magic quickly took the ticket, while they hurried on the train as they heard the railway conductor yell: "All aboard! Last train to Ponyville departing!"
They managed to get on and breath a sigh of relief, as they sat down on the nearly full train. He looked out through the window, enyoing the scenery and thinking of a lot of things. Mostly his mind haunted him with this thought:
"Did i make the right choice leaving Canterlot?"

HEY. Thanks for reading this far!!!! Hope yall have fuuuuuuuuuuuuuuuuuuuuuuuuun and enjoy! 
Stage 1
The train was nearing Ponyville when Bolide finally realised that he was so lost in thought, that he forgot to read the letter that Thunder Wing wrote.
“My dearest, Bolide hex!
I have, of course, began to notice the changes around Ponyville. Half of the town is sick, and yet still no solution to any problems. No medications to ease the symptoms, to cure this weird disease. I began to keep a distance from sick ponies and creatures alike, scared i myself, would catch it somehow. We dont even know how it spreads or occurs! And i just now heard Canterlot is going into a quarantine, so it must be something serious. I was wondering on going back to my home town at the Bat hills, but im still not sure. I heard rumours, and some say that cutie marks of infected ponies can fade away! That they become itchy, peckish and even their sight is going worse! Im on the edge of just grabbing my stuff and flying home. But ill think about it, and let you know if i do so. Stay safe!
Yours truly,
- Thunder Wing"
"Yep maybe i shouldve read this before deciding to just go willy nilly into the sick town. Too late to go back now i guess," Hex thought as the train rolled into this cursed town.
The pony put on his saddle bag and swiftly got off the train and made his way towards the town hall. He looked around trying to guess where the towns library could be, coming to the conclusion that its somewhere on the south side of the town. As the unicorn trotted along the path towards the archive he saw some sick ponies, who mindlessly walked near the houses. Bolide sped up his pace trying to avoid ponies who may be sick.
Soon enough he was in front of the oak tree which looked very inviting. They raised a hoof knooking twice on the scarlet red door then waited a little only to be met with a friendly smile from the princess of friendship herself, who seemed to be a gentle natured mare but some fatigue was noticable on her.
"Hello. How can i help-" The princess started before being caught off guard by the other pony who bowed down. "Oh no need for that," She chuckled with a soft smile.
"Are you sure princess?" Hex asked as he stood up and towered over the alicorn.
"Yes, Yes i am sure. But anyways as your probably know im Twilihght Sparkle. And you are...?" Twilight asked softly having to look up to see the other ponies face.
"Oh- of course, im sorry- My name is Bolide Hex. A friend of Thunder Wing, who im searching for currently. I belive he is staying here, right?" Hex questioned, while looking inside the tree curiously.
"Thunder wing? Yes he is here. He never said he was excpecting visitors, but please, do come in." Twilight said walking back in, to let the other pony in.
The library was a little messy, books all over the floor stacked weirdly in the corners, threatening to fall at any moment. Half of the shelves empty and the biology and medical section completly cleared out onto the floor. A little green and purple dragon running around putting books back and taking them off from shelves. Twilight quickly went up on the stairs and there talking queitly to another pony, before fast wing flaps could be heard. A light violet furred colt flapped their sharp membrane wings, - and like thunder - striking down Bolide hex to the oak wood floor.
"Hex! your here!" The bat pony cheered as he stood over the unicorn, who currently tried not to groan from the hit they took.
Thunder helped up Hex, with a grin that quickly turned into a confused look.
"But how come your here in ponyville? Canterlot is in a lock down! You should be there, where its safe!" Thunder asked with a small concerned whine. "But that means your stuck here! Hex this is bad! Very bad!" Thunder added with a worried huff.
"Im pretty sure thats not how it works Thunder. But if it is ill gladly stay to help. I assume you do need help?" Bolide turned his head to the princess, whos nose was already deep in a few books, reading frantically.
"Huh? oh!- yes i.. uhm yes, all helping hooves are appreciated," Twilight said rubbing her left eye with her purple hoof.
The day passed by rapidly. It was almost midnight when the two bookworms, finally got their noses out of the pages, and agreed to give up on reading, after Thunder Wing and Spike scolded their ears off.
"Im sorry, Bolide Hex but youll have to share a bed with Thunder Wing. I dont have anymore mattresses, let alone beds for you to sleep in." Twilight explained with a small yawn.
"Its alright, really. Im already thankful i have a place to stay and a roof above my head." Bolide reasoned with a soft smile.
"Sleepover time!" Thunder exclaimed happily, while hugging Hex.
Soon enough all of them made their way to their bed. Thunder and Bolide walked towards the guest room that Twilight offered them to sleep in. Quickly diving into the bed, not wasting a second of potential sleep. The moon shining down on them, shushing them to sleep like a faint lullaby. While each and everyone hoped, Queen Luna would watch over their dreams, and fend off any nightmares that would try attack their psyche.
But barley two hours later Thunder and Hex were waken up by blood curling screams, and a loud thud on the window.
Bolide immediately checked what the thud, only to find a horrifying looking pegasus trying - and somewhat succeeding - to crack open the window.
"S-she doesnt look like she wants hugs," Thunder stuttered out, terrified from the sight.
The pink ponies skin was coated with dried and fresh blood, their eyes red, bloodshot and glassy. Their Mane and tail, presumably falling out or pulled out, along with most of the fur. The pony looked hungry, very hungry. But the fresh blood around its mouth seemed to tell that it allready feasted on something. Or someone.
"Even if she is, she wont get 'em here!" Bolide hissed, his horn glowing bright green, opening the window, to instatly lazer blast the wicked pony off, and quickly closed it back.
"What happened to that pony?!" Thunder questioned, frightend. "You dont think its..." The colt trailed off even more fearful. His eyes wide open, still shaking from the absurbity of the situation.
"... if it is, were in a living nightmare. All the other sick ponies they, -" Bolide gagged, feeling their stomach hurl. They tried to not to panic, but considering an apocalypse could have just started, was horrifying.
"Ill go get Twilight." Thunder muttered as they dashed to the said mare's room.
Bolide crumbled down to their knees, trying to procces what is happening, or what will happen now. Half of the town, - if not more - has been reported to be infected. And if the diseases spreads to all of Equestria... Every pony and every creature is doomed.
When Bolide eventullay came back down to earth, he noticed a magenta colored force feild around the library. Twilight, Spike and Thunder rushed into the room.
"Thunder told me what happened! Are you okay Hex?" Twilight asked with a worried look.
"I- i think im fine. But, I cant belive this happened. What if its that disease?!" Bolide asked, panicking slightly.
"I have put up a force feild. no one can get in or get out unless i let them. Were safe here for now. However i think it is the disease. We immideatly need to warn everyone whos not infected!" Twilight stressed, looking at spike who already grabbed a quill and scroll starting to write an emergency letter to the Queens.
"The hosptal must be swarming with zomb-ponies!" Thunder shuddered, knowing damn well they were in trouble.
"We must do something! We cant just sit by, while half of the town is eating the other half!" Hex exclaimed , getting up from the floor and looking out the window, hearing more screams of innocent ponies, and terrifying growls from the monsters.
"Youre right. But we cant just go and do whatever we think is right without a plan. If we want to be quick and safe, we need to let my friends know. They can help with getting the uninfected ponies here." Twilight explained, turning her head to look at Thunder Wing. The colt knew what was coming.
"You... need me to get word to your friends?" Thunder Wing worded Twilight's thoughts.
"Im sorry to ask you this, but we have no other way of contacting them. Youre the fastest out of all of us, and if i fly too far from the force feild, it could give out." Twilight insisted, shaking her head apologetically.
"But thats basically suicide! Even if hes fast he cant possibly out fly - " Hex tried to disagree, before Thunder cut them off.
'I'll do it. You dont have to worry Hex. Im going to be fine. I swear." Thunder said with a comforting smile, hugging the tall pony with his right front hoof.
Bolide didnt really like this plan, if you could even call it that. Hex didnt want their friend just flying around the town, while its flooding with vicious monsters, who want to feast on his flesh. He could just only stand by and watch how his best friend grabbed his saddle bag putting it on his back, while Spike helped him put away some food, water and a scroll with a list of the 5 other ponies address. Twlight used her magic to get a baseball bat down from the wall while walking to Thunder, who was already at the bottom of the stairs.
"It isnt much but, at least youll have something to defend yourself with." Twilight said looking at the bat with a scowl, not daring to look Thunder in the eyes.
Thunder nodded taking the bat with his mouth, biting down on it tightly. His hooves neared the door when he looked back at Hex, while opening the door. He gave him a small smile, before Twilight opened a small hole in the force feild. Thunder took a deep breath before taking off, flying out of sight.
"While Thunder is getting my friends, we need to make this library a safe haven." Twilight said while already teleporting book on top of each other, stacking them to make makeshift beds and laying all the blankets and pillows they have on them. Ordering Spike to get the food and water they have home and put it on the table thats in the middle of the room. Making sure, anyone who gets here will have a chance to eat, drink and get some shut eye, in this apocalypse.
