This is an AU story using the RWBY universe and elements from the military, Japanese lore, a few other shows and things totally made up my me.

I do not own RWBY or anything pertaining to other shows.

Please be aware of that this is an AU and things will be different to the cannon version. I will not have an upload schedule due to having a full-time job at a factory. Furthermore, I would like to note that this story will be dark at times and themes will be a little more adult latter on so I set it as M.

With that said, Do know that this Chapter is not required to read as the story starts next Chapter. This Chapter breaks down what is AU in the story. Please enjoy as this is my first story and reviews are welcome.

Introduction-

Remnant is a world of legends, none more prominent than the story of the fifth kingdom. The four kingdoms deny the existence of such a place as it was said to be on a continent southeast of the kingdom of Mistral in the ocean that separates the kingdom of Vale from Menagerie, the island to which humanity tried to exile the Faunus. This kingdom was known as Dellhaven named after the capital. Dellhaven has a climate much like Vale, with Four seasons but with a wild winter and a longer summer. Large plains and rolling hills in the west and large snow-covered mountains to the south make up most of the terrain, it was a beautiful place. But with all places in Remnant the creatures of grim are always present making it hard for the local citizens to claim this untamed land.

The people of Dellhaven are made up of three races, (yes three), Humans, Faunus, and lastly the Kitsune. The Kitsune are a race like the Faunus in the fact they have ears and a tail, but that is where the similarities end. With the Kitsune they have both ears and a tail wile Faunus have one trait, two is rare but not unheard of. The Kitsune have fox ears and nine foxtails, this lead to them to be known also by the name of nine tails do to this easily recognizable trait. What truly sets the Kitsune apart from the other races is that they are all immortal. Now they are not invincible, it is that they stop aging after they turn 23 years old and forever stay young, they can still get diseases and be killed just as easily as a Human's or Faunus, this lead to persecution by humanity due to the fact they do not age.

The other main ability they have is the ability to shapeshift to look like anyone down to the aura they give off, this comes at the price of it doubles as their semblance. They cannot copy a semblance however. When a Kitsune changes form for all intents and purposes that is their new body, meaning they can look however they want at any time forever as it does not require them to maintain any form. A Kitsune will revert to their original form upon death or if a special talisman is used, but no over way can one force a Kitsune to show their true form. As stated before a Kitsune is for all purposes their body whatever it is will be just that, not even a doctor can find the difference when a Kitsune decides to mimic someone. The Kitsune also found a way to weave dust into their clothing to shape with them so that they don't need to buy clothes for each form they have.

The third and last thing that makes the Kitsune unique is the fact that all Kitsune are all born female. Many change and live as men but all true forms of the Kitsune are female. It is not uncommon to see same sex couples in Dellhaven, as Kitsune are considered both male and female as they can change genders at a whim. Dellhaven also has equal rights laws that guarantee rights for all three races, discrimination against any is heavily frowned upon within the kingdom.

The Kingdom of Dellhaven-

The Kitsune founded Dellhaven nearly 700 years before the great war, when the four kingdoms were just formed, after humanity had persecuted the Kitsune for their immortality, thinking that they could find a way to harness it for themselves. As well as their similarity to Faunus made it all the easier for humanity to alienate them. So, humanity hunted the Kitsune to the point they fled. With what few remained of their people and the few Humans and Faunus that had sided with them they came across an undiscovered continent, hidden from the rest of the world by a large expanses of water. The remnants of the Kitsune and the others with them settled and built a small town that they named Dellhaven. This became the rumored fifth kingdom and for a time Dellhaven grew and prospered unknown to the rest of the world. Dellhaven was a kingdom that had thrived in the shadows of remnant. With its capital, Dellhaven, at the base of a mountain and rolling hills in front, perfect for farming, they named it Dellhaven as it was a haven from the ones who pursued them, as well to prevent the confusion of the capital of Mistral, Haven. Many other towns and cities grew up in the peace that rained in Dellhaven.

When the war broke out between the four kingdoms, Dellhaven refused to reveal itself to the world as they feared it would mean the utter destruction of its people. This did not however prevent Dellhaven from participating in the shadows. Dellhaven was not without its army and navy to fight the grim and if it came to it, the other kingdoms. (The navy ships look like the warships from Call of Duty Infinite warfare but can't go into space) Dellhavens military was larger than Atlas's military as Dellhaven doesn't have huntsmen to help. The pride of the military where the marines, elite men and women who were some of the best trained and equip units they had. It was decided that a volunteer force was to be sent to aid the Vale army in the war under the cover of a mercenary group. Only the 901st Marines volunteered to go. The marines fought for 7 long years in the war and when the war ended they faded into the smoke of the aftermath returning to Dellhaven without anyone even realizing they were involved. Again, for just over a hundred years they sat in isolation until the Faunus revolution came and Dellhaven once again sent the 901st to help, this time when they returned they brought many Faunus refugees back with them. This isolation continued for 80 more years, until the fateful day it all came crashing down and nearly started the second great war. And this is where our story begins.
