Prelude
The Milky Way Galaxy. Sagittarius. Zero Star of Sagittarius. The Galaxy Star Cauldron. It is here, at the center of the galaxy, where everything began. It is here where everything will ultimately end, and thus giving birth to anew. It was here from where all stars are born. Suns, planets, moons, comets, asteroids, creatures... Yet all things, no matter how big or small, must have a beginning. Life is no exception. All stars are born from seeds which are created at the Cauldron. These 'star seeds' as the people came to call them, were the source of all that existed; without them, nothing would exist.
For a long time, planets were on their own; planetary travel was a thing of science fiction. However, some planetary systems could travel within their own star systems. But when an advanced race found ways to open wormholes throughout the galaxy, thus allowing countless peoples to travel between stars and planets without affecting their home planet's time, galactic trade ensued. The galaxy was split into 12 sections, and while I could go over each one in detail, it is not necessary. What's important was that the center of the galaxy, where the Cauldron was, was called Sagittarius, which meant, 'Divine'.
For many cosmic years, war simply did not exist, except on single planets. There was simply no reason for galactic-scale war. The only time anyone ever thought about it was in fiction. There was an eternal peace.
Until the defect.
The Cauldron gave birth to a star seed that didn't fully mature; for some reason, the seed left the Cauldron before it could fully mature and crystallize. The star seed eventually became a dark cloud that devoured other stars like a black hole. As it fed, it grew in power. The people came to view this cloud as the symbol of death and destruction, and prophets believed that the end was near.
The dark cloud was known as 'Chaos'.
After what seemed like an eternity of fear, the unthinkable happened: the dark cloud took the form of a woman. A woman with black armor, blood red eyes and hair, pale skin, and wings like a devil. Desiring power and domination, she took growing star seeds from the Cauldron and gave them a fraction of her power, making them strong. Eventually, she gave birth to an army. An army that numbered trillions, and were so spread out throughout the galaxy that no one could tell them from normal people.
When she finally revealed herself, she called herself 'Sailor Chaos' and her children were the first Sailor Soldiers, ruthless warriors who would stop at nothing to achieve their goals, even if it meant sacrificing a loved one.
One by one, stars lost their light to the Sailor Soldiers' unmatchable powers and determination. The galaxy had never seen anything like this before; each Sailor Soldier in the army had their own individual powers, so there was absolutely no way to predict what they were going to do next. Not even the most powerful and advanced armies in the galaxy could stand up to the might of the Armies of Darkness.
As for Chaos herself, every single assassination attempt against her ended in failure; she wielded a black sword and wore black armor that seemed to pulse with evil, and not even the bravest of hearts could stand up against that aura. Even those crazy enough to break through her aura were brutally killed because Chaos was absolutely astounding with her sword. There was no hope.
Until Chaos' first child, Sailor Nebula, came across something neither she nor her brothers and sisters had seen before: a young child crying over a dead mother. The child had looked at Nebula with a look of pure sadness and agony. The child was so lonely, and the feeling somehow made Nebula change. By her duty, she was to destroy anything that wasn't darkness, but for some reason, she couldn't. Instead, she secretly took the child as her own. She named her Kiboh, which means 'Hope'.
Kiboh grew up to be a beautiful woman under Nebula, who had disappeared from the army. Nebula came to like this life even more than the dark life she'd been living. She began to see just how people lived, and soon knew what had to be done.
Nebula infiltrated many of the Sailor Soldiers' fortresses and convinced many of her siblings to join her cause. Those that refused, she killed to keep her plan secret. Many of them required to see Kiboh, and that alone was usually enough to make them change.
After Nebula had a good strong foundation, she made her move. This was not the first time one of Chaos' children had revolted, but they were only trying to destroy their mother in hope of taking her place. Not Nebula. She intended to establish peace once Chaos was destroyed.
When Nebula attacked, Chaos was caught completely off guard, and defeated quickly. Nebula then journeyed to Zero Star of Sagittarius, the very center of Sagittarius, and built a castle called Star Castle over the portal to the Cauldron. She became the self-proclaimed Queen of the Galaxy, and her star seed, the Saffer Crystal, became her heirloom. When she died, Kiboh inherited the Saffer Crystal and became Sailor Hope. She continued the peace that her mother had started and became known as one of the greatest rulers of all time.
Over time, only the High Order, that is the Queen and her subjects, even remotely remembered Sailor Chaos and the Army of Darkness. Star seeds of Sailor Soldiers became known as Sailor Crystals, and the Sailor Soldiers themselves became defenders of justice, and their leader was a warrior called Sailor Alpha, one of the most powerful Sailor Soldiers ever, who had bested Sailor Hope in a dual. Any remaining Soldiers still loyal to Chaos were scattered and divided, and became known as Shadow Soldiers. Sailor Hope passed down her mother's legacy to her child, Sailor Epona, and then to her child, Sailor Ursula, all the way to now, Sailor Angel. Every one of these Queens kept the peace, and galactic-scale war was once again forgotten.
At least that's what the general public thought…
