The history of the planet was a long one. Kingdoms, Empires, Republics, Federations, many had risen and fallen through out history. But, this story, it takes place in what is known as the five kingdoms in modern times.
Back in the era of colonization, explorers from the Osean, Verusan, Usean, and Anean continent encountered what would eventually be known as the kingdoms. But, they were surprised to find natives, and while some were human, others were not. These people were known as Faunus, human-like people that had animal traits like ears or tails. But the most incredible thing about these landmasses was the one of a kind resource, Dust.
Of course this sparked quite a few conflicts, but eventually the natives of the landmasses were able to hold their own against the colonial powers due to the power of dust despite their smaller populations and armies. After what was called, "The Dust Wars", peace was made and trade agreements eventually sprouted. But to protect themselves, the landmasses formed five kingdoms and formed an alliance to protect themselves against hostile powers.
These kingdoms came to be known as Atlas, Vacuo, Mistral, Vale, and Menagerie which had a mostly faunus population. Despite tensions between humans and faunus', the worry of another invasion prevented any conflict.
And so, from 1492-1980s, the five kingdoms were able to keep themselves out of most conflicts. Even though most of the larger nations could defeat the kingdoms, both Dust and the alliance would make it a very costly victory.
Unfortunately, both inside and outside the kingdoms, trouble began to brew in the 1980's.
In the kingdoms, tensions between humans and faunus began to rise. With the threat of invading powers looking less and less likely, some humans began to discriminate against the faunus while the faunus and human sympathizers tried to protest these actions. Despite peaceful intentions, some of these protests turned violent, causing tensions between those in Menagerie who wanted peaceful resolutions and those who wanted action.
Meanwhile on the Osean continent, the country of Belka, which had been a major power despite being smaller than rival powers Osea and Yuktobania, had begun to face an economic crisis. This came to a climax in 1987 when the Belkan government amended a federal law review in December 17.
This allowed parts of the the country to secede and become independent. This allowed Belka's neighbor, Fato, to claim parts of Belka's northeast territory, giving birth to the Fato Federation.
Then in 1988 the rest of the northeastern territories formed the country of Gebet and established Mons as their capital.
Finally, what would become a catalyst in the future, in May 12, the southeastern territories broke off and formed the Republic of Ustio. Instead of helping the economy, the territories breaking off only seemed to worsen the situation.
In 1991, in order to help the economy, Belka sold its northern lands to Fato and it's Great Lakes region to Osea, the largest country on the Osean continent.
And thus, ignited the spark for the Rald party, an extreme right wing political party, to take control of the government with "the promise to restore peace and prosperity to Belka".
And then, March 25 1995. The date that changed the world. It was at this time that Belka discovered natural resources in Ustio. And so they prepared for war.
But they were not alone.
Earlier in 1995, the Belkan government helped separatists overthrow the ruling government of Menagerie in a silent coup de dat.
Working together, with the power of Belka's engineering and the legendary Belkan airforce, and Menagerie's dust and dust-based technology, they declared war against their neighbors in a war that engulfed the world.
The Belkan war had begun.
On the Osean continent, with the help of Menagerie's dust, Belka invaded Osea, Recta, Gebet, Fato, the Kingdom of Sapin, and finally Ustio in a blitzkrieg that smashed all resistance.
In the five kingdoms, with the help of the seemingly unstoppable Belkan air-force, Menagerie invaded Vale, Vacuo, and Mistral while sending support to rebelling faunus and human sympathizers in Atlas.
In just five days, both countries conquered huge swaths of land, seeming completely unstoppable.
By March 30, on the Osean continent, nearly all of Ustio falls to Belka, with only the southern mountains remaining free. With Ustio's 6th air division suffering massive losses the government reformed it into a foreign mercenary unit.
It was at this time that the four kingdoms, the invaded counties on the Osean continent, and Yuktobania all formed an alliance to combat the Belkan-Menagerien alliance.
Thus the Allied Forces began their counter attack with the assistance of Ustio's mercenaries, several of which would become famous by wars end.
Slowly but surely, the Allied Forces began to push Belka back while the four kingdoms defense forces held the line against Menagerie.
Then, in May 13,with the liberation of Ustio's capital Directus, the invasion of Belka began.
With their homeland being invaded, Belkan air-forces in the four kingdoms were called home, opening the way for the Allied Forces counter attack in the four kingdoms.
In May 30 the Allied Forces in the kingdoms began 'Operation: Beacons's Light', an amphibious invasion of Menagerie. With the assistance of Ustio's mercenaries, including the famous "Galm swuadron", and the Menagerie loyalist army, the Allied Forces managed to capture the beaches and establish a foot hold.
In June 6, the capital of Menagerie was taken and the War in the kingdoms was over. Unfortunately while the kingdoms celebrated, Belka, refusing to let the Allied Forces invade the "Fatherland" of the north did the unthinkable.
The Belkan's detonated seven nuclear weapons along the Waldreich mountains claiming over 12,000 civilian lives.
Horrified, the fighting had completely stopped on the Osean continent. Through this tragedy, the Belkan government was able to reform and overthrow the Rald party.
In June 20 all powers involved in the war met in the Belkan city of Lumen for a peace treaty, thus marking the "official" end of the Belkan war.
But while the powers tried to discuss peace, trouble slowly brewed.
In December 25, the terrorist organization, "A World With No Boundaries" revealed themselves. Made up of forces from all the powers that took part in the war, they used the heavy command cruiser "XB-0 Hresvelgr" to bomb the city of Lumen. Fortunately, the Galm squadron managed to destroy the cruiser when it attempted to destroy Valais Air Base, where the remaining Ustio forces had once gathered in the beginning of the war.
In December 31, the Allied Forces located 'The World With No Boundaries' headquarters at Avalon Dam, a site where Belka at initiated 'Project Pendragon', the creation of a V2 MIRV Nuclear weapon combined with Dust.
Working together, the Allied Forces initiated an invasion of Avalon Dam on the same day. Despite frightening casualties, the Allies were able to clear the way for Galm team to destroy the facility and prevent the launch of the V2.
And thus, the Belkan War ended. But, the funny thing is that despite failing that day 'The World With No Boundaries' eventually got their wish, the world began to change.
Eyes widened, the student and her classmates excitedly waited for their teacher to continue the history lesson.
"So, now we can move on to-" The teacher began, only to be interrupted by the bell ringing, much to the disappointment of his students.
"Aww come on!" The student wined.
"Yeah! It was just getting good!" Another student complained.
Smiling, the teacher said "Calm down kids. While I'm happy that your eager to learn, class is over..." But seeing their disappointment, he quickly added "... But I'm sure we can pick this up tomorrow."
Hearing this, the students cheered as they paced out and headed out.
"Bye Sir!" She and multiple students said as they walked out the door.
Waiving goodbye, the teacher sat down and looked out the window.
He had always enjoyed the view, even though others would bee put off by the large crater visible beyond the horizon.
