Alright, let's give you all some context on where we are and why it is like it is.

On the North-East border of Equestria lies the city of Vanhoover, A relatively small player during the war. Vanhoover mainly served three purposes, two of which only came into play during the war.

The first of these was the housing Ponies and other refugees wanting to make their way to the Crystal Empire on the promise that it was neutral ground. However, a lot of refugees never made it. Most individuals wanting to escape the war weren't ponies at all. A lot of them were griffins who either had families or didn't want to go into the mercenary business. Others were zebras, driven from their homes in Equestria as a result of the anti-stripe sentiment that the war created. Of course there were ponies who had no interest in the war among them too, alongside other creatures who felt their homes were no longer safe.

The second purpose was the importing and exporting of goods in and out of Equestria, they did border the North Luna Ocean after all. Vanhoover's trade was what kept the city alive. Salty air from the ocean wouldn't do farmland any good, which tends to be a problem when you have a city full of vegetarian creatures. Equestria as a whole needed coal and lacked many deposits of it, meanwhile the zebras had plenty of coal. The zebras needed gemstones to work their magic, but lacked them, Equestria had plenty of them. Vanhoover had the means to transport the goods. Alas, when the war broke out Vanhoover lost one of its main trade deals. Crippled they had to focus their efforts on trading more with mainland Equestria if Vanhoover was to support its population

The third purpose was defense. A city on the edge of Equestria easily accessible by sea? That's a prime point for the Zebras to invade. And so, Vanhoover became a priority in Equestria's defense. Anti-air cannons were constructed in case of dragon attacks, barracks were built to house troops to combat enemy infantry and many of Vanhoover's ports were re-purposed to arm, repair and service the many battleships built to repel any invasion by sea. However, this often clashed with the refugees. Every train that passed through Vanhoover would have to be stopped and searched for potential spies who would wish to sabotage Vanhoover's defenses. This, coupled with Equestria's sentiments towards others during the war led to a lot of "spies" being forcefully removed and placed in prison encampments until their innocence or guilt could be proven.

Within only a few years Vanhoover became A shield for Equestria, defending her from any and all invasions, whether they were actually a threat or not.

Of course, none of this mattered when it was all engulfed by balefire on the 23rd of October, 2077, the day the world ended. Now of course you don't need me to tell you about that, this was all around 176 years ago and it shows. It kills just as effectively now as it did then too! Although I'm sure I don't need to tell you about that either, I'm sure you're all more than familiar with radiation, mutated monsters and the average wasteland asshole. In fact I didn't need to tell you any of this at all! The average wastelander simply focuses on how to live just one more day, I would know, that used to be my mindset as well. Emphasis on the "used". So what changed? What series of traumatic events occurred and in what order to make me change the way I perceive the world around me? Well it all started with one job. A job that would leave me gallivanting about the wasteland, briefly stopping to scoop up a friend or acquaintance here and there and ultimately leave me where I am here and now, talking to you.

My name is Oak Burner, and this is the story of how I slowly managed to make my way home.

Author's Note

And here we are, the obligatory prologue that comes with every Fallout: Equestria story.
Oh boy, first time writing a story and I've so far managed to just dump exposition all over the rug... I'll have to clean it later. In the meanwhile, all I can do is hope that I'm better at actually telling a story, rather than just setting up the basis for one.
