Long ago , people lived in peace , bathed in the warmth of light.
Everyone loved the light.
Then people began to fight over it. They wanted to keep it for themselves.
And darkness was born in their hearts.
The darkness spread swallowing the light and many people's hearts.
It covered everything and the world disappeared.
But small fragments of light survived...
In the hearts of children.
With these fragments of light , children rebuilt the lost world.
It's the world we live in now.
Originally, the χ-blade was the counterpart of Kingdom Hearts, for which it acted as protector. The Master of Masters studied the χ-blade and learned to extract Keyblades from people's hearts as a result.
In the aftermath of the Keyblade War, a conflict over the Lux of the world, the χ-blade splintered into twenty pieces: seven fragments of pure light, which eventually become the seven princesses' hearts, and thirteen shards of darkness. It is unknown what became of the thirteen shards of darkness.
The χ-blade and the Keyblade War itself passed into legend in the generations after with the cause of the war itself being distorted by the legends as people came to believe that Keyblade wielders who sought to take the light of Kingdom Hearts for themselves and created "Keyblades" in the image of the χ-blade, and they clashed together in the legendary Keyblade War.
" I been having these weird thoughts lately , is any of this for real or not "
Sora has been having weird thoughts lately and wondering what is real. In a surreal dream-like place, Sora is separated from his two friends; a red-haired girl named Kairi and a white-haired boy named Riku. Sora finds himself guided by a mysterious voice in a stained-glass void, which foreshadows the events that will soon take place.
He ends up being swallowed by a monstrous creature , and is awakened by Kairi on the beach of Destiny Islands, revealing it was a nightmare. Riku motivates them to work on their raft in order to explore new worlds. While fetching supplies in a cave, Sora encounters a mysterious hooded figure in a secret cave who ominously speaks that this "world" has been connected and tied to the darkness. He accuses Sora of lacking knowledge and then disappears.
One night, the islands are attacked by darkness and shadow creatures. Sora seeks out his friends, finding Riku first; Riku disappears into darkness, curious about what it contains. Soon after, Sora obtains a mysterious weapon, the Keyblade, to defend himself. Using it to fend off the creatures, he heads for the secret cave, where he finds Kairi near a door. She turns to him, saying his name as the door behind her blows open. The ensuing blast of darkness sends Sora and Kairi both out of the cave. With Kairi nowhere in sight, Sora fights the creature from his nightmare, meaning it was more than a simple dream. A gravitational pull sucks Sora up into the sky and into a void as the islands are destroyed.
He felt like he was laying on a cloud. Cocooned in softness and warmth. A nearby window is opened and outside the room , the city is abuzz with the Founder King's Day festivities.
" what a dream... " Sora mumbled aloud as he begins to stir.
" you're finally awake. We were starting to worry. "
The strange voice caused him to jerk up. Sora was sure he'd never heard anyone speak with such an odd accent. Looking around his eyes landed on someone wearing a purple and black patterned dress shirt with a black suit. He wears glasses and has short, dirty blond hair swept up at the front of his hairline and green eyes. Sora eyes drifted slowly around the room. Sora doubted even the Mayor of Destiny Island had a room the same size. Or as grand looking. The massive bed he was laying in hardly took up any space.
" Hello , where am I , and who are you ? " Sora asked looking back at the man near him.
" My name is Ignis Scientia as to answer your other question you are in the Citadel. This is the city of Insomnia the capital city of Lucis "
" so this is not a dream , but how did i get here "
" you fell from the sky "
Sora felt like his brain had short circuit. He'd… fallen… from the sky. For a brief second.
" How ? " Sora asked. All he could remember was being pulled into a void of darkness.
" I am afraid I can not answer that Sora. But, I think I may know someone who can help you. "
" Wait , what about my island ? My home ? My family and friends ? Are there here ? " Sora asked suddenly as the memories came back to him.
" I am sorry , but only you appeared yesterday. Falling like a meteor above Lucis. You are lucky it was the Glaives that found you. And that they brought you here. This country had been at war for many years with another country. "
" War ? but everything looks peaceful "
" because of the king and the wall Lucis is able to enjoy peace for at least 150 years. The king must give up his strength to maintain the wall. "
A sudden sound interrupted the two.. panicked screams then filled the streets outside the window.
It is M.E. 734 , Ardyn has set foot inside the crown city of Insomnia.
" Testing 1..2..3.. Is this thing on ? Greetings , people of the Kingdom of Lucis. Do forgive me for interrupting the festival. But i must tell you this day will be your last... Call it divine retribution. Sins of the past must not go unpunished. The time of reckoning is at hand. "
Ardyn infiltrates the city and summons Ifrit to cause carnage before disabling the Wall amplifiers. Ardyn defies Besithia's withdrawal orders to go after King Regis, intent on forcing him to summon the Old Wall to settle the score with Somnus. After Ardyn nearly kills Regis, the king's Ring of the Lucii summons Somnus's Lucii form. The ring is a magical heirloom given by the gods and the past kings' souls are collected inside it rather than "passing on". While trading blows, Somnus gradually admits his regret for what he did to Ardyn and confesses that he was jealous for being outshined. After losing to his brother, Somnus tries to explain himself, but Ardyn is outraged at his brother's audacity in asking to be understood after taking everything from him. Somnus wishes Ardyn will find peace as his spirit disappears.
The still-furious Ardyn is about to kill the unconscious Regis when the Astral Bahamut intervenes and pulls Ardyn into his domain where he reveals the Astrals' new purpose for him: to cover the world in darkness and be killed by the True King as a sacrificial lamb, allowing him to find peace in death while also satisfying his revenge. Ardyn can either reluctantly submit, or defy his fate. If he submits Ardyn demands to know if Aera and Somnus knew of his fate. He receives no response and screams in anguish over the betrayal. If he rejects that fate he is tortured into accepting it by Bahamut.
Once back on the mortal plane, Ardyn finds himself in Angelgard. He laments that nothing matters anymore and accepts the role he is to play in plunging the world into darkness, his plan to kill the True King once he comes.
