The two kingdoms had formed an alliance. Mistral provided the small kingdom with goods unavailable in the frozen tundra. In return, Mantle introduced technological innovation, as well as guidance in the settlement of Anima's cold northern territory.
An incident in Mantle led to a strange and unexpected decree - the abolishment of the arts and the repression of self-expression. The people of Mantle had come to believe that they would be much safer from the Grimm if they could simply keep the emotions of the masses in check.
The people of Vale had a problem with this. Well, they had a problem with a lot of things Mistral and Mantle had been up to - treatment of their citizens, use of slave labor and their constant insistence that their way of life was what was best for everyone.
Despite cries from his people, he insisted on sharing the land with the settlers from Mistral. But… (sigh) To this day, no one knows who shot first, but what began as a riot between two bands of settlers… would suddenly become the first battle of the Great War.
On the battlefield, this meant a temporary ceasefire in order to deal with the monsters before returning to the fight at hand.Those left miserable back at home, however, were often helpless with their best warriors away fighting the "good" fight.
A lot of settlements were lost during these years, and most were never reclaimed. Rations on food and Dust were put into effect, development of technology accelerated, Humans and Faunus who fought alongside one another became closer and every day, mankind grew more and more efficient at destroying itself.
The king of Vale personally led his army into battle alongside the soldiers of Vacuo and decimated the enemy forces. Crown atop his head and armed only with a sword and his scepter, he laid waste to countless men.
Territories were redistributed, slavery was abolished, governments were restructured, and the Warrior King, the last king Vale would ever have, founded the Huntsman Academies and placed his most trusted followers in command of each kingdom's school.
He would teach the world to fight, so long as we promised to fight for ourselves and never against ourselves.
