The one hundred year war has been ongoing through two generations and end doesn't seem in sight. To understand who it's between and why we have to go back to when it started.
1904
During this time life is taking place like normal. From racial injustice towards minorities to separation of class by wealth. No one dared expect creatures to emerge from elves, werewolves, sirens, vampires, and banshees. They first acted kind and temporarily acted like humans to gain their trust. They had been acclimated to loving with humans for a long while they were seen higher than minorities but lower than white rich people. It seemed all fine and dandy until whispers of a takeover began. It was brushed off and laughed about because no one would ever imagine these beasts, non humans who quickly became 2nd class citizens to take over the entire Earth, that was obsurd and surely would and could never happen.
The rumors dies as it never takes place and takes us to the 1920s, no change has happened of anything could be seen as it has gotten worse, less than people treated badly. But the unthinkable happens those very rumors brushed off seems to have held truth as small riots of supernaturals began to occurr. No one imagined it would go far but when small civil wars began happening with humans against supernaturals it was easy to see this rumor shouldn't have been so easily overlooked in the early 1900s.
By halfway mark of the 20s a war has been officially called a civil war, the name in history would be The war of underestimations, seems cheesy but it speaks the truth no one considered supernaturals a threat because they silently waited in the background when the guards of the people, the humans who had the power to get things done was gone. Now they strike and they are coming to win.
This war was said to be quick and easy but quickly became the war of 100 years.
Soon in a blink of an eye it's 2020 and the war seems to be worse than ever. The humans have lost all hope the day it was announced the world is under supernatural rule.
Welcome to the new earth, now called United Factions. Where humans are 2nd class citizens with barely any rights the humans who were white and rich felt how it was for the minority groups. But there's no end ever….
