Arc 1: Incunabula

Chapter 1:

The Key of Darkness approaches its course... to bring the dark age of humanity once more. The twin goldens, both chosen by fate, born to fight the dark enemy. But the dark one marks the other, the chosen Key of Destiny.

Through love and hate creates another, chosen by fate to fight with the chosen's warriors. This child made by love and hate, shall defy its master. By love and hate, this child was made, shall deny its master...To follow no one, but his own reflection.

Dawn and Twilight destined by fate, even if only one shall remain. It's very destruction, the final piece... to finally rid of the dark enemy.

Blue eyes slowly opens as he sees the place surrounded by darkness. Then a bright pure light surrounds him as the ground below shows many figures of the people that he'll soon meet.

Roxas notice his brother in one small circle along with some of his friends all visible within the portraits. He could see his form that seemed to be in a deep sleep. In his hand, his very own keyblade.

But the other half seemed vague. A figure was also there with the same pose, but it showed no one. Roxas observed the mysterious figure beside his own glass, wondering who the person could be.

"Hello?" Roxas called out.

"I'm here."

Roxas turned and saw no one, but the voice called out once more, "You can't see me, but I know that you can feel me."

Roxas was confused, but decided to talk to the voice instead, "Where am I? What are these?" He looks down at his the form of himself and his friends.

"It's your heart. These people are those who will be connected to you in the near future."

"But..." Roxas paused as he saw the blank figure beside his own form, "Who is that?"

The voice didn't answer. Instead, three pillars surfaced up revealing three objects by its pedestal. A sword, a staff, and a shield.

"Pick one."

Roxas at the pedestals and observed the objects around him, "What are these?"

"This will determine your own path. But in order to chose one and gain another, you must sacrifice one to obtain all."

"Oh..." Roxas gave a nod even if he was still confused.

"Remember, Roxas, there is power within you. But only you can know its true form. This will be your strength so choose well."

The voice didn't utter anymore and all was silent. Roxas then took the chance to walk on the first pedestal. There lies the shield.

Roxas touched it and the voice resonates within his ears, "The power of the guardian. Kindness to aid friends. A shield to repel all."

The blonde nodded at the information and puts his hand away. He went toward the staff and touched to hear its core, "The power of the mystic. Inner strength it wills. A staff of wonder and ruin."

'I'm starting to see which is not something that I wanna take.' Roxas thought as he went to the sword.

With a touch of his hand, the voice called out, "The power of the warrior. Invincible courage it shall give. A sword of terrible destruction."

Roxas nodded as he finally went back to the center. He looked up and called out the voice.

"Hey, I have already chosen what to pick."

"Very well. What will you give for your chosen path and for you to gain the other?"

"Mystic, I'll give that up."

The shield and the sword turned into a small ball of light as it floats towards Roxas. It all went into his heart as the staff and the pedestals disappear from sight.

"The path of the warrior, with the ability of the guardian. You have set your own course. I wish you luck for your journey, Roxas."

"Wait!" Roxas called out from high above, "Who are you? Why do you know me?"

"...I don't know as well, Roxas. I was wondering in the darkness, then I felt your light. You're like me, but stronger..."

"What does that even mean?" Roxas tried to call out once more, but he saw his body slowly becoming transparent.

"You're waking up... I hope to see you soon, Roxas."

-Twilight Town, Foslux Residence-

"Seriously, Roxas, WAKE UP!"

Roxas let out a yelp as he was pushed away from his bed with the blankets wrapped around his body. He stood up and glared at his other twin.

"Seriously, Ven, can't a guy get some sleep, here?"

Ventus, his younger twin by a minute, huffed and glared at his older twin, "It's already 10 am in the morning. Plus it's time for our keyblade creation ceremony!"

Roxas' eyes widens as he immediately untangles the blanket from his body, "Oh yeah! We're already 13! Sweet!"

"Yeah, you lazy butt, remember that Van already had his keyblade a couple of weeks ago." Ven utters as he watches his brother get dressed, "You would always tell Axel about it, and here you are being lazy."

"I just slept in late, last night!" Roxas huffed, "Look on the bright side though, we'll go to Disney's Awakening of Magical Students."

"Yeah, we'll be able to see Terra, Aqua, and even Axel!" Ventus beamed, "Even if they're a year ahead of us, they're excited for us as well."

"Can't wait for Axel to see my keyblade." Roxas grinned as he finished fixing his hair, "Alright. Let's go down and meet up with dad."

Vanus Foslux was a man in his early thirties with blonde spiky hair and green eyes. He's one of the head of the Department of Keyblade Secrets where they study the possibilities of every weilder and its blade. The world that they live in has numerous worlds connected into something bigger and the number of keyblade weilders grew numerously. With the help of many world leaders and brilliant minds, gliders, armors, teleportation devices, and many more were invented to produce a safe travel throughout many worlds.

Vanus is man appointed by the governors, he does his job well. But he still wouldn't trade his time for his twins.

Vanus smiled as he saw the family picture in his hands. Beside him in the picture was a beautiful woman with brown hair and blue eyes. In their arms were their bundles of joy, Ventus and Roxas. But a tragic event made his twins lose their mother at the age of one.

"Oh, if you could see them right now, Rosa." Vanus whispered as he admires the beauty of his wife, "They're thirteen now and their keyblades will resurface. Both of us blessed our sons to have it and I know that they'll use it well."

"Dad!" Vanus saw his twins running down the stairs in excitement. The older man laughed at their antics.

"You know, I could scold you for running down the stairs, but I'll make it an exception since I know what it is today." Vanus laughed as he ruffled their hair.

"Wait, you won't go to work?" Roxas asked, his eyes glittering with happiness.

"Why of course, Roxas." Vanus grinned, "It's a special day for my boys and I want to make sure that I'll be there to see your keyblades."

"Alright, dad!" Ventus whooped, "It won't get you in trouble, right?"

"Nah, they could kiss my ass for all I care." The older blonde laughed, "If they said that they're professionals, all of them can handle a day without me."

The twins both high fived in excitement, "Yes!"

"Alright, sunshines. Great your mother first then have some breakfast. We have a lot to do, even with getting some school supplies." Vanus utters as he pours them some orange juice.

The twins nodded as they ran toward the altar where some offerings and incense are present. But in the middle is a picture of their dear mother, Rosa Foslux.

"Good morning, mom!" The two of them greet in a bow, "Today is that day!"

"We'll be getting our keyblades now, mom!" Ventus grinned.

"So we hope that you'll watch us. We'll make you and dad proud." Roxas said.

After a few prayers, they joined their dad for breakfast and some conversation between the family.

The twins admired the view from above while riding their dad's keyblade glider. Vanus' glider is styled as a motercycle with two seats attached for the twins. Ventus and Roxas both grinned at the thought of having their own keyblade gliders.

"You'll be learning all of this when you enter school in a few weeks. My last teacher was Professor Doofenshmirtz and I heard that he has retired already." Vanus told his twins.

"I wonder who will be our glider teacher then?" Ventus wondered as Roxas nodded.

"Well, Tadashi Hamada is also working in the same department as me. So from what I've heard, it may be his brother who'll be teaching you." Vantus pointed out.

"Wait, Hiro Hamada? But he isn't a keyblade wielder like his brother, right?" Roxas asked.

"Yeah, but he knows a lot about gliders, heck, he and his brother made an exact replica of it. Besides, Hiro has already been teaching there for three years." Vanus answered back, "He had no complaints and a lot of them learned how to make or imagine their gliders. My previous professor was also like that."

"You're right." Ventus nodded, "Remember that he became Aqua, Terra, and Axel's teachers. You don't hear them complanin."

"Yeah." Roxas agrees.

Vanus smiles at his twin as he notices their excitement and curiosity for the upcoming school year, "There will be a lot of things you'll know in Disney. It's both for Keyblade wielders and non keyblade wielders. As long as you have magic and a strong heart, you'll get in."

"But there are three houses there, right? Guardian, Mage, and Warrior?" Ventus pointed out.

"Yes." Vanus nodded he continued talking, "Guardians are those who had the desire to protect and guide. Mage, the use of magic for wonder and knowledge. Warriors, the brave soldiers who fight for what's true and right. Different houses, but they have something in common."

Vanus closes his eyes as he held onto his chest, "They both use their heart as their guiding key."

Ventus and Roxas stare and understood every word with awe and fasination. Both of them are now determined to prove themselves to whatever house they will belong.

"I would be proud no matter what house you're in. Your mother was a Mage and I was a Warrior. In my younger years, I was a bit rash and stupid... but I was lucky that your mother fell in love with me." Vanus smiled at the fond memory.

Ventus and Roxas sadly smiled at the mention of their beloved mother. Both knew what horrible fate Rosa faced to keep the twin safe.

Both twins hardened their gazes as they knew who Vanus was talking about.

"Yes, him. But he's dead now. Let's just hope that it's for the better." Vanus tightly gripped thehandles of his glider, "Oh, we're almost there. Buckle up, boys, we're going to land."

-Land Of Departure-

After Vanus willed his keyblade to return back to normal and disappear, the twins stare in awe at the big castle in front of them. The older blonde laughed at his sons' enthusiasm as he leads them towards the castle.

"Merlin is already here along with Master Yen Sid." Vanus informed his sons, "They will be using some spells for your keyblades to come."

"Wait, do you mean Master Yen Sid?!" Roxas exclaimed.

"The Headmaster of Disney's Awakening of Magical Students?!" Ventus finished the sentence with the same shocked look Roxas has.

"Yes, he's always there to every ceremony. Master Yen Sid was also there when I was my keyblade got materialized." Vanus grinned, "Now close your mouths, boys. We must look proper as we are seeing the Keyblade Master himself."

The twins nodded as they followed their father inside. The castle was truly big and surrounding it were statues of different Keyblade Masters throughout the previous era. Ventus and Roxas soon glared at one statue standing tall to its pedestal.

"Why is he here?" Ventus glared at the statue, "After what he has done..."

"But he was a Keyblade Master, Young Ventus."

Ventus and Roxas turned to see the source of the voice. Yen Sid walked down the stairs along with Merlin, approaching the Foslux family.

"Keyblade Masters are always remembered, regardless of their deeds or power. It reminds us of stories and lessons that can serve purpose in coursing our own river." Yen Sid lectured as they both stood in front of the Foslux Family.

"Greetings, Master Yen Sid and to the Great Wizard, Merlin." Vanus bowed as the twins copied their father's action.

"Greetings, Vanus." Yen Sid returned the greeting.

"Nice to see that you're looking fine, Vanus." Merlin smiled, "Ah, I see that Young Ventus and Young Roxas have grown up. How time flies so fast."

Yen Sid nodded, "I'm sure it would be the proudest moment a father could have as well."

"Ventus and Roxas have been dreaming about this for their whole life." Vanus replied, "The moment the boys turned were born, Rosa and I knew that they would be strong Keyblade Wielders."

Yen Sid went forward and observed the twins. Roxas tried to keep his cool as Ventus fidgeted. The old Keyblade Master could see the determination within those blue orbs and nods.

"Usually, a Keyblade Inheritance Ceremony occurs during the age of eight. But these two are the exceptions. Only a mere baby, your ceremony was reckless, but it showed that they truly have the potential." Yen Sid smiled at the twins.

"Thank you, Master Yen Sid." Roxas and Ventus said in unison.

"Alright." Merlin called their attention, "We must move along and begin the ceremony. There will be a couple of younsters coming in in a few moments."

Yen Sid nodded as he urged them to follow. They all followed the Keyblade Master as they went up the stairs.

"Um, excuse me, Master Yen Sid." Vanus called him, "Is Master Eraqus with us today?"

"Oh, he said that he'll be attending something important. But he's kind enough for us to continue the ceremony without him." Yen Sid stated, "He also pointed out the same question to why you didn't continue your Mark of Mastery."

Vanus chuckled, "There are some important things that appeared in my life, Master. I'm already content with what I have rather to have that title."

"It's still open for option though, Vanus." Merlin said, "You're free to do it again."

"Wait! You almost became a Keyblade Master, dad?" Ventus asked.

"Of course, though I just dropped it all." Vanus then paused as he saw the dejected look of his sons, "Don't give me that look Ventus and Roxas. I already told you that my family is more important than some title."

"But, you could have been in a greater place, dad." Roxas pointed out.

They all arrived at the top but Vanus paused and kneeled in front of his sons. He looked at their eyes that reminded of his late wife.

"Roxas, Ventus, having you in this world made me realize a title even greater than being a Keyblade Master. Losing your mother is much worst than not becoming a Master. There are a lot of things more important than those titles, my sons." Vanus smiled as he saw the twin nodding.

"Put those frowns upside down. This is a day for joy." The twins nodded as they grinned. With a content sigh, Vanus stood up and led his sons to where the two great masters are standing.

"Now, Vanus, please stand beside us as we begin our ritual." Merlin instructed as Vanus followed in suite.

Yen Sid cleared his throat as he used his magic to conjure a symbol below the twin's feet, "This will awaken your keyblades. Just be still as Merlin chants the spell."

Roxas and Ventus stares in awe as the symbol below them. They weren't able to guess what Merlin was uttering as they felt something warm coming from their hands.

Ventus felt the wind surrounding him as it created a bright shining whirlwind. Ventus raised his left hand as the bright winds slowly formed a key. He held onto the handle and with a quick back slash, his keyblade showed his form.

"Wayward Wind." He whispered in awe.

Roxas saw the symbol below him changing its form into the same thing he saw in his dream. He then felt a string of light coming toward him and it tied onto his wrist. Numerous balls of light along with those mixed with the dark swirl around him, showing its beauty like stars above the skies. Roxas instinctively spread both his arms wide as the balls of light and darkness quickly took form of keys. As he held onto the handle, two keyblades appear and the spheres spread out away from him.

"Oblivion and Oathkeeper." Roxas utters as he admires his blade.

When the symbol disappeared, Roxas could feel numerous eyes staring on him.

"Woah! Two keyblades!" Ventus stares in awe, "Cool!"

"My, this is a rare occurence, Master Yen Sid." Merlin even had his eyes wide open at the events.

"Indeed."

Vanus quickly went to his sons and ruffled their hairs, "Nice Keyblades, boys. I could already tell that it's stronger than mine."

"Indeed."

They all turned as they heard Yen Sid clearing his throat, "Wayward Wind has chosen Ventus. It's core very light and powerful. Roxas has two blades choosing him. Oblivion, its core is dark and powerful. Then there's Oathkeeper, the opposite for your dark keyblade."

The twins grinned at their new keyblades as they admire the shape and form.

"Now, your keyblades are a part of you. Just will it to disappear and it will do as you wish." Yen Sid instructed.

Ventus and Roxas nodded and did a they were told. The keyblades in their hands disappeared.

"You have shown such exemplar talent and skills. With Merlin and your father as witnesses, Ventus and Roxas Foslux you are welcome to study in Disney's Awakening of Magical Students." Yen Sid congratulated them.

"Alright!" The twins cheered in unison as they high fived.

"Though I must warn you both, especially you Roxas. Yours keyblades are strong and it could lead you to many great things. The Dark Eye was one of them with a terrible deed, but great it truly was."

-Union Cross Island-

Union Cross Island is an island of numerous markets and stalls. But with the help of magic, the beauty of nature still remains. Products from different worlds came to this island to show and sell to different customers. It is also the place where their school supplies are selling.

After letting the light barriers off Vanus's glider and willing it to disappear, they now stroll onto the busy streets.

"Well, it's almost school season." Ventus sighs as tries to avoid some people from bumping him.

"Ugh, I smelled someone foul a couple of minutes ago." Roxas grumbled.

"Busy crowd, busy schedule." Vanus replied.

"Great Kingdom Hearts, it's the Foslux twins!"

Roxas and Ventus now stiffened when they noticed the crowd slowly gathering towards them.

"Here comes the paparazzi." Ventus muttered under his breath.

Vanus sighs, 'So much for normal shopping day.' "Ah good morning to you all, ladies and gentlemen." The older blonde civily greeted the masses.

Ventus and Roxas waved at some of the crowd. Even if they hate the attention, it would be better if they were to act as civilized as they can to the crowd.

"Reckon that they already have their keyblades, eh?" A man with a pirate outfit asked.

"They aready have theirs." Vanus replied, trying to already end the conversation, "But my sons are a bit shy to show it to them."

"Aw, we would hope to see the blades of the great Foslux twins."

Vanus's eye twitched, "Excuse us for a moment but my children and I have some errands to finish."

The crowd was about to spout another conversation when suddenly they felt something change the temperature.

"Excuse me ladies and gentlemen, but all of you are distrupting our business here."

The Foslux family saw a familiar figure standing at the farther side of the crowd. A woman in her mid thirties with blazing red hair and green eyes.

"Good lord, it's Leila Flareian, the mayor and head business manager of Union Cross Island!" one of the woman exclaimed.

"She was know as the Phoenix Queen in the previous war with the Dark Eye!"

"Aunt Lea!" Ventus and Roxas exclaimed.

Leila huffed as she marched past the crowd and towards them, "Early morning and there's already a problem for you, Vanus."

The older blonde chuckled, "It's really a pain in the ass."

The red haired woman chuckled as she showed her flaming wings scaring majority of the crowd, leaving them alone.

"Alright, it's all settled." Leila grinned as the flow of the crowd returned to normal.

"Woah, your flame powers are still cool, Aunt Leila!" Ventus exclaimed.

"Aww, you still flatter me, little Ven." Leila giggled as she ruffles both their hairs, "At least those blockheads are out of your way."

"Thanks, Leila." Vanus grinned.

Roxas then interjects, "Anyways, where's Axel?"

Leila sighs and replies, "He's with his hotheaded father. Xeros apparantly asked for a father-son bonding, where they would find a place to let out some steam."

"So, they're wrecking havoc with flames and keyblades?" Roxas deduced.

"Exactly." Leila chuckles, "Apparantly they don't want to repeat what happened when half of our homes were burned and destroyed."

The twins nervously chuckled, "That's Axel for you."

Leila then accompanied them to Corona's Bookstore and Stationary as they all exchanged conversations. As they reached their destination, Leila decided that they should part ways.

"I still have some things to manage. There are a lot of idiotic baboons who couldn't would try to scam the customers and vice versa." Leila pinched the bridge of her nose.

"It seems tough to handle a whole island, huh?" Ventus asked.

"It sure does, but at least you get to keep some jerks in line. Plus bossing some of those douchebags around is my stress reliever." She chuckled, "Anyways, conratulations on getting your keyblades and being a part of Disney."

They waved at the red haired woman as she parted ways with the Foslux family. After that, Vanus gave the list of supplies to the twins, "I'll wait here while you get your books. Pick out some that you like as well."

The twins nodded as they enter the store. Numerous books and materials are present at every corner. Roxas and Ventus circled around the shop looking for their materials. They were almost finished when they noticed a boy with brown hair reading something from the shop.

"Hey." Ventus called out, "The shop said no reading."

"Oh." The boy noticed their presence, "Don't worry, I'll buy this. They allow me to buy three books of my choosing after I completed my book list."

The brunette then closed the book as he reaches out for two books from the shelves, "Here's the book of Magical Properties and Spells. One of the books needed for our year."

He put the books at their respective baskets and smiled, "So you're like me, right? First years?"

The twins nodded, "Disney?"

"Yes, I'm also going to Disney." He then offers his hand, "I'm Sora by the way."

"I'm Ventus Foslox, call me Ven."

"I'm Roxas Foslux and I'm older than him."

"For one minute!"

Sora chuckled, "I can see that. I'm sure that I'll be able to handle which is which. And I know about you two, but don't worry. I'm not interested in making both of you uncomfortable."

The twins brightened up at the response, "Thanks for understanding."

"No problem, goldies."

The twins chuckled at his answer. Roxas then replied, "Say, you don't have a sirname?"

Sora's eyes widens as he nervously chuckles, "Well -"

"Sora!"

The three of them turned as they saw two familiar figures entering along with their father.

"Ventus, Roxas!"

The three of them quickly ran towards the adults while carrying their supplies.

"Hey, kiddos, look who's with me today." Vanus pointed at the two adults.

"No way!" Ventus exclaimed.

"Master Eraqus and Ansem the Wise!" Roxas exclaimed as well.

"My, it's the Foslux twins." Eraqus greeted the twins.

"I see that you've already met Sora. He'll be one of the students in Disney." Ansem said.

Vanus went to Sora and said, "I'm Vanus Foslux, I'm their father. Nice to meet you, Sora."

"Nice to meet you too, sir. Oh yeah, Ven, Roxas, they helped me with getting some of my supplies." Sora replied back.

"Why though?" The two asked in unison.

"Well," Vanus interjected, "They told me of Sora's predicament here. He's an orphan yet he's able to weild a keyblade as well. Master Yen Sid has given him an invitation to go to Disney as well."

"Not only that, Vanus." Eraqus replied back, "He is pretty knowledgable with the worlds and some of history. Thus, we decided to help him with his situation."

"There were some books that I could read about it. So it's not that hard." Sora sheepishly grins, "But still, having a keyblade is so cool."

"Yeah! Also, you should join us when we get to the lightrail train." Ventus said, "It's better if you join some familiar crowd, Sora."

Eraqus pats Sora's shoulder and nods, "He's right. I'm sure that you'll enjoy the ride. It seems that they want to be friends with you as well."

Roxa nods, "You could also meet our friends. They're nice and I'm sure you'll fit in just fine."

Sora smiles as he accepts the offer, "That would be great! Thank you, Roxas and Ven."

"No problem." Both of them grinned and replied in unison.

Vanus smiles at his boys, "Well, it seems that my twin sons have already made a new friend. Don't worry, Sora. I can assure you that raise them to be good boys."

"I'm sure they are, Mr. Foslux."

Ansem then glanced at the time in his watch and cleared his throat, "Best we get going. Even if Sora is our charge, there is still curfew in his orphanage."

"Hope that you also keep this a secret though." Sora utters as he looked at the twins.

"Don't worry-" (Roxas)

"Our lips-" (Ventus)

"-Are sealed."

"Thanks. See you all at the station." Sora waved at them as he left with Eraqus and Ansem after paying the supplies.

Vanus smiled at Sora's form, "He's a pretty nice kid. Treat him well, okay boys?"

"Yes dad."
