The SCP Foundation, an organization that has existed for thousands of years, an organization that survived the near extinction of their species, an organization that has always been in the shadows, but will one slip-up bring them into the light?

What if someone wanted it to happen?

Based off SCP: CB
Takes after the end of season 8

For many a millennia he has slumbered beneath the earth, his strength recovering from a conflict as old as the sands it was fought upon. For many a millennia he and his people withered away into legends, spoken of by the elderly to their young as nothing more than stories before bed. For many a millennia the world itself forgot about this being, hidden away within a cage of dirt and rock and time.

But now he has awoken to find himself lost in a world nearly unrecognisable, dominated by a species he'd not laid eyes upon for many, many years indeed.

Yet there still lived a select few who knew him personally. To them, he was an old yet dear friend, long believed to have been lost to the cataclysm that cost him his people and his kingdom. Despite all the time that had elapsed and despite all that had happened throughout the years, they still knew his name.

Cyrus Perennem, 'The King Without a Crown'.

It has been said that nothing lived on the land of Equestria before the three pony tribes became one and settled there. It has also been said that ponies cultivated and created Equestria with their own hooves.

This is wrong.

Thousands of years after the cultivation of Equestria, Zachery a human soldier whose sole task is to protect the human race is allowed to take a leave of absence. It has been thousands of years since the last pony sighting and being in constant state of wartime is deemed too stressful for both the militants and civilians involved.
While this is happening, Twilight Sparkle an alicorn princess of Equestria unearths information on a lost race that lived in Equestia thousands of years ago. Unknowingly to the both her and Zachery, she slowly sets into motion the events that will cause the two species that had violently divided to once again meet. For better or for worse.

The year is 952 and it is a golden time for the Kingdom of Olenia, homeland of the deer. Industrial revolution has reached their northern lands, new discoveries help them shape the land to be livable and trade routes to Equestria and far beyond have brought immense wealth to the land. Ships bearing the white-blue antler flag are welcome in all the harbours of the world.

Yet it is a fickle world of politics, table talk and negotiations that keep the world operating — something that young Korpi Lehto finds himself thrown into. He is made to join the Grandeur Embassy as an advisor due to his mastery of foreign languages. Not only does he need to now keep himself — and half the time his companions — safe and solve tense diplomatic issues but also uphold a noble family legacy in a changing world.

Thankfully there are many friends to be made on his adventure stretching a lifetime.

This story is based on the Equestria at War -mod for Hearts of Iron 4. However the lore is greatly expanded upon for story purposes. Some characters referenced are from the mod and belong to their creators as do the base lore, location names etc. created for the mod.

Please support the mod by subscribing to it at Steam Workshop and playing it if you can. It is truly a terrific mod with great amount of work and detail put into it.
