(Start)

Young Xehenort was quite peeved and no doubt so was his most future self. They had taken Sora from his mark of mastery to make him into his XIII Darkness but their plan backfired. Not only did the new Master Riku learn of this scheme but so had Yen Sid and the King. In doing so they had entered the dream world and rescued Sora from his entrapment.

Now even though their effort was for not they did get one good thing out of it. Sora had lost the power to bring rise to the other Guardians of Light which meant they had bought time before beginning the Keyblade War. But Xehenort through time was smart even after creating XIII Versions of himself which were currently at XII they always knew to cover their bets with back up plans. Thus Xehenort from the past went off to locate another to take the place of their 13th Seeker of Darkness.

He traveled back to around the time before Sora had begun his adventures which meant Ventus was still asleep, Aqua was still in the Realm of Darkness, and Terra was still his future self's vessel. So it was no surprised when Xehenort had found himself in a different London where he made his way to Scotland and in turn located a school. It wasn't hard for him to see through the magic meant to make it look like an old abandoned castle as he had a hunch that Merlin the Wizard who was in Radiant Garden about now was quiet possible born in this world.

Now he's not one for such thing when it didn't make importance of the now. But for the time being he was focused on the events going on. Xehenort had easily blended into the crowds of students using magic and their own uniform to stay hidden. Plus he had come across a hidden room that he had stayed in before scouting about. The small creatures House Elves had called it the come and go room though Xehenort cared little for it. But upon his arrival it didn't take him long to see that this world was trapped at the intersection of Light and Darkness that it's tipping in a very unstable manner.

Xehenort figured if this balance is not restored the world here will more than likely destroy itself to try and put itself back together. But again it was a theory he had no intention to pursue until a later time.

It was his hiding that he came across the 'Golden Trio,' as they had their adventure in Hogwarts. As he saw them it was easy to pick out how they reminded him of Terra, Aqua, and Ventus, following up by Sora, Riku, and Kairi, then Axel, Xion, and Roxas. Though Axel or Lea eventually got his heart back and regained his light or will eventually regain it and gain a Keyblade as well Xehenort noted that there always seems to be three in some way.

These three he could tell were destined for tragedy be it by the manipulations of those with good intentions, or the machinations of those with dark intentions. These three will suffer more than they should as Xehenort could already see the boy who lived one Harry Potter was at the center of it. But in Harry's heart he saw two hearts. One but a fragment of another possibly a failed attempt to mimic what his future-self had created or perhaps a basis for what he had created.

Xehenort saw the two hearts inside him but most of all inside Harry's heart he saw the same type of Darkness Ventus had so long ago. Perhaps he had located the needed 13 Seeker of Darkness through this boy. But the question was how to go about it creating another Vanitas would be a tad bit dangerous but from what Xehenort had seen the boy was protected by the spirit of his mother. Her heart shielded his own heart from the darkness as well as the body from the darkness invading his mind and soul ever so silently. Xehenort knew how to pick them out and he knew creating another Vanitas may be needed here.

The concept of the XIII Seekers of Darkness or the True Organization XIII was to gather Nobodies and in turn put Xehenorts heart of Darkness into each of them. In turn they may begot the Keyblade Wars against the 7 Guardians of Light. But this had caused setbacks for them as well as Sora and Roxas both rebelled against them. Vanitas may be another of the XIII Seekers of Darkness but they still need there Number XIII. So Xehenort continued to observe the boy who was black listed by his peers for speaking a language considered dark. But he saw the boy and his friends were quiet adept in improvising in many situations.

But when they went looking for the Chambers Xehenort had visited Hermione Granger in the Hospital Wing and observed her. He saw she was a seeker of knowledge with the right form of it she could possibly be tempted but then again from what he had seen she was loyal to Harry Potter. Of course he realized she may still be able to see and perceive him despite her petrified state thus gave her an obscure riddle like he had many others.

She may not understand it but it should keep her off his trail for the time being till he finishes what he came for. Thus he followed the two boys and the fraud of a Professor into the Chamber where the fool wiped his own memories using a broken foci and followed after Harry as he went to save the girl inside.

It was there he found that the fragment had another. This was interesting but fragmenting your heart like this had a limit. Xehenort had created his XIII by basically copying his heart and inserting it into his vessels. The boy would have proven to be another 'Voldemort,' if the foolish snake had bothered to realize the benefits of having living Horcruxes. These anchors would allow him to roam freely but also be able to protect themselves be they aware or unaware of the fact they were soul anchors.

The perfect defense is an animal whose sense of self-preservation would allow the fragment to flourish. But seeing as Voldemorts heart was unstable after so many shaves it was no wonder the boy had a weak fragment. From the shadows of course he observed waited and watched as the vents play out. If the boy survived then Xehenort will have their 13 darkness at long last.

(Start Present Time Chamber of Secrets)

Harry dodged the Basilisks strikes as best he could, it was so fast. The only thing that probably saved him from instant death was the fact that it was blind, that and Fawkes was flying around making himself a nuisance with its sound and scent. Occasionally the bird would dive in front of the beast distracting it leaving it open so Harry could slash at it. He would then have to move as quickly as he could to dodge the serpent when it attacked in his direction.

"Damn you Potter, and damn that bird!" The specter known as Tom Riddle, the younger version of the Lord Voldemort. He then began to hurl spells and curses at the bird, attempting to rob Harry of his ally.

Fawkes true to his Falcon like nature dodged the spells. This process repeated itself several times until at last Fawkes was hit, his right wing completely blown off. The magnificent bird landed with a loud thunk near the Ginny and the Diary.

Now Harry was alone facing the Basilisk, and was now even more hard pressed to move about it. Suddenly he found himself in a corner. Seeing that Harry was cornered Tom let out a hissing order to the Snake.

"In front of you, strike now!" He hissed out in the snake's tongue.

The great beast reared its head back and then began to strike at Harry. Harry acted on pure adrenaline and instinct, he forced the sword of Gryffindor's point forward and impaled it into the beast gaping maw. The blade traveled effortlessly through the beasts flesh, almost like butter, and stabbed into the beast's brain. Killing what may have been the last of the terrifying species of snakes.

However Harry's victory was short lived. In Stabbing the beast in its mouth he felt one of the fangs of the beast pierce his right shoulder, cutting tendons and muscle, breaking his bone, and worst of all filling his blood with the deadliest poison known to the mystic world.

Harry pulled his limp arm from the dead creature, the fang stayed in his shoulder and came with him as he moved away. Tom seeing the fang in Harry's shoulder let out a laugh of triumph.

"It is over Potter, The venom of the Basilisk should soon melt you from the inside out. The girl will die and I shall be reborn. All because she wrote in a silly little book." He laughed.

Harry hearing this, came up with a last ditch effort to win. At this point he knew he was dying he could feel the venom coursing through his veins his heart felt like he was burning. But he would not allow the most sociopathic, mass murdering, nut fuck that Voldemort was walk free again.

Limping over to the diary he pulled the fang from his arm as Tom saw the fang and the diary realizing what he was about to do. "What are you doing? No! Stop!" Riddle lunged forward, watching in horror as Harry plunged the fang into the center of the book, black ink spurting everywhere. Riddle started writhing in pain. His body started blurring again. Riddle screamed right before he vanished and Ginny woke up and saw the state Harry was currently in.

"Harry!" Ginny called out as she looked to Harry with worry.

"Don't worry." Harry said as he held his arm beginning to lay down a bit. "Ginny, you need to get yourself out." Harry ordered unaware of Xehenort watching the entire event from the shadows. "Follow the Chamber and you'll fine Ron." Harry said as he looked to Ginny who clearly didn't want to do it.

He lay there waiting for death to take him into her loving embrace before he then heard the cry of Fawkes and then felt something on his chest. Harry smiled to the phoenix before he spoke what may very well be his last words. With every ounce of strength he had left he lifted his head and opened his eyes to gaze at the one winged figure that was Dumbledore's Familiar. "You were brilliant Fawkes." Harry began as he looked to Fawkes. "I just want quickly enough." Harry said as he smiled sadly to the red bird was crying onto his arm. For a second he had hope Phoenix tears had healing qualities. And the tears worked as the injury vanished leaving nothing but a scar behind.

"Of course…" Harry said realizing what Fawkes did. "Phoenix tears have healing powers." Harry said as he looked to Fawkes for his deed. "Thanks." Harry said as he smiled to Fawkes before looking to Ginny. "It's alright Ginny." Harry said assuring her the truth as the two began to smile at Harry's survival.

But then a new voice was heard as they all heard it. "You have no idea." A new voice spoke as Harry and Ginny both soon heard footsteps. The two looked and in turn saw a dark portal of sorts open and from it a black cloaked figure walked out. Harry and Ginny saw this as this figure they couldn't tell much but something about him just screamed darkness somehow. "Harry Potter I have been observing you for quiet sometime and I must confess." He began as he walked to the duo as Fawkes stood protectively over the two. "You have exceeded my expectations for one as young as yourself." He said as Harry saw this cloaked figure here.

"Who are you?" Harry asked as the man then gestured to himself before speaking.

"My name is of no importance." He said as he then pointed to Harry. "But you may know me as your ally when you accept the darkness inside you." Xehenort said as Harry was confused as Ginny was scared again.

"The Darkness?" Harry asked as he saw the Sword of Gryffindor was still in his hands. "Where did you come from how did you get here?" Harry asked as he would have known if they were followed in her.

"I come from a place beyond the boundaries of time, beyond the veil between worlds." Xehenort said gesturing to the ceiling but was in fact meaning the sky above the chamber and castle. "I have observed your exploits this year Harry Potter." Xehenort said as he pointed to Harry. "And you are just what we need for our 13th Seeker of Darkness." Xehenort said as he then spread his arms out to the sky once more. "XIII Seekers who will battle the 7 Guardians of Light and in the resulting conflict known as the Keyblade War… the true X-Blade will be born." He said trying to basically entice Harry to his future selves cause.

"I don't want to fight in some war." Harry said as Xehenort heard this and saw it coming as well. "Especially one who is using this darkness." Harry said as he always believed darkness wasn't evil but was something to be warry of.

"Unfortunately you do now have much of a choice in this matter." Xehenort said before he lifted his arm up and snapped his fingers.

Soon Neo Shadow Heartless appeared around Harry and Ginny as they all glared at him as Harry got into a battle stance. "If you wish to best these Heartless you must unleashed the darkness inside." Xehenort said as he looked to Harry as he got Ginny to safety.

"Never!" Harry called out as he took a shaky battle stance.

"Shame." Xehenort said as he looked down upon Harry as Harry saw an image that will haunt him forever of a tank skinned youth with topaz yellow eyes and silver hair under the hood. "I do have other means of changing your mind." Xehenort said as the Neo Shadows began their attack.

Harry slashed at one as the sword did damage to them but not much as Harry was forced to the defensive quickly. The Neo Shadows began to hound at Harry as every time he thought he got one they popped up from the ground showing they had hidden in the ground and shadows. IT wasn't long until one of them grabbed Ginny as she cried out in shock as Harry saw this.

"Ginny!" Harry cried out but it was too late as Harry was knocked down and out as the Neo Shadows restrained Ginny.

"Harry!" Ginny called out in shock as she knew she was no match for this guy as he was clearly a seasoned veteran and these creatures attacked in hordes.

Xehenort walked over to Harry as she then saw a key shaped weapon appear in Xehenorts hand as it looked to have a demons head and a clock like design to it. "A pity you declined your training would have been hard but you would have at least stood a chance." Xehenort said as he walked over to Harry. "Perhaps… your darkness will be more willing." Xehenort said as he then held his Keyblade over Harry's chest.

"Harry!" Ginny called as soon the Keyblade shined and in turn shot a black beam with gold highlight into Harry's chest as he then gasped in shock from it. From the light now on Harry's chest it began to spread to his scar as soon two balls of light shot out from him as they began to float about a bit. To Ginny's shock they circled around each other before melding together as even Xehenort made a shocked sound as once the two balls collided a large sphere of darkness formed.

Soon it began to clear revealing a figure inside it as the figure was in a fetal position before spreading its arms and legs as judging by his build the figure was male. Harry gasped a bit more before falling back down unconscious as he passed out from the pain. Fawkes was of course unable to help as he was trying to protect Ginny for Harry but now he had failed Harry who was hurt and possibly dying again.

The new figure gently floated down and landed revealing himself to be wearing a black and red organic suit with a dome like helmet and a black and red tail coat of sorts. "Empty creature born from the riven of Harry Potters heart…" Xehenort began as he looked to the figure. "To you the name…" Xehenort began only to be cut off by the figure as this was shocking as well.

"Alexander." The figure said in a male voice as he looked to his hand for but a moment. IT was all he needed as he then clenched his fist in turn as he then glared at Xehenort. "Alexander Enigma." Alexander said as Xehenort then saw this as something was amiss here as he then looked to Harry and saw he still had his heart in one piece.

"Very well then… Alexander Enigma I welcome you to the True Organization XIII." Xehenort said as Alexander walked over to Harry and looked down on Harry.

"Organization XIII?" Alexander asked as he looked at Harry. As he looked to Harry he felt a combination of different emotions… rage… anger… sadness… grief… sorrow. He had no idea what they were but they hurt… they hurt so much as he then clenched his fist trying to piece together what little memories he had. "As in I serve under them with no freedom?" Alexander asked as he looked to Harry some more.

"In perspective in the name of knowledge through the Keyblade War." Xehenort said as Alexander… hated that. Rage formed again but one with a target… he hated it being manipulated being used he despised it and he had no idea why… was he manipulated or was he too much of a rebel.

"No…" Alexander said as to Xehenort's surprised shadows began to from under Alexander and from it the Unversed appeared as the flood glared at Xehenort… at this man who would play chess with his life… whatever he called a life. "I serve NO ONE!" Alexander roared out as soon a keyblade appeared in his hand as with it he made quick work of the Heatless.

Xehenort was caught off guard as Alexander began his assault as he was forcing Xehenort to the defensive as he realized he screwed up. He had miscalculated an unknown variable as from what he was seeing the two fragments must have joined together to form this new creature. But that wasn't possible the darkness of the second heart wasn't strong enough to form an actual being. Even if the Third Heart had compensated the darkness of this creature was strong… unless the fragment from the diary had somehow managed to join with the creation. In turn it was allowed to gain sentience to a state that Vanitas had not gained.

Xehenort jumped back and quickly summoned his time glyph to shield himself. "Another time another place perhaps." Xehenort said as he soon escaped through the tunnels of time as Alexander slammed down his Keyblade onto the spot Xehenort was at previously.

Alexander then looked to his keyblade and saw it was serpent base as it seemed to have a serpent coiling around the shaft forming a more sword like appearance. The hilt wrapped around the guard as he noted it was similar to the statue of Salazar Slytherin but with a demonic eye at the hilt. The teeth seemed to have a sort of bat like ring to it as the chain at the end of the hilt had a charm of a snake stylized as an S.

"Serpents Cunning?" He asked as that was… yes it was his Keyblades name. This Keyblade that would be used to fight in some Keyblade War… a War he had no interest in. As he looked, he had little to nothing save for a name he granted himself… a weapon of his own heart… and nothing else. Who was he… what was he… where did his beginning start.

Alexander looked around the room under his helmet and figured this would be appropriate as his birth place and in turn marking this day as his day of birth. Ginny and Fawkes glared at Alexander as he began to walk over to the two as his Keyblade vanished in a flash of dark green. He leaned over Harry and kneeled to his head as he quickly dispatched the phoenix and girl with a wind based spell.

"Mark my words." He said pointing to Harry with his right index finger. "We will meet again… I don't know who or what you are but just looking at you… causes me pain." He said as the rage, the grief, the sadness, the envy, and the sorrow flowed around and through him caused just by looking at Harry and in turn creating more Unversed as he knew that was there name. He then stood up leaving Harry be as he opened a Corridor of his own which he entered and vanished to.

"What was that?" Ginny asked as she looked in shock to the boy Alexander Enigma as she didn't know if he was Harry's brother, clone, or son considering he came from Harry himself.

(Potter Vaults)

Unaware to many at the Potter Vaults in Gringotts the Family Tapestry magically began to move as it connected one Lily Potter nee Evans to another. From it began to connect her to another… one Tom Riddle as it formed into another piece into one Alexander Enigma… or as it seemed to call him Alex Riddle. Though his image was clear to see, he was a man with crimson red hair and topaz yellow eyes as he seemed to be glaring at the world.

Destiny has changed this day as now the, prophesy no longer has but one Chosen but through the acts of a man seeking knowledge two chosen have been born. One to begin with and the other as the power he knows not. But will these two join hand in hand or will the creature of darkness act upon its nature and consume all in its path. Only time and fate will make clear on the oncoming future of this world.

(Scene Break Hospital Wing)

Harry shot up awake with a gasp as he looked around in confusion before he tried to calm himself down. "What happened?" Harry asked as he felt his chest and felt he was ok… but the Chamber Ginny, Ron. Harry looked to his side and saw Hermione still there but as he looked he then wondered if he can un-petrify her. But as he looked to her he then looked to his hand and felt his scar and noticed it felt different somehow. Harry then focused a bit more and then as if by instinct his hand move to grasp something.

As he did this to his shock in a flash of fire a Key like weapon appeared. The hilt was modeled after a lion as he noticed how the shaft was like a wider variant of the Sword of Gryffindor. But what shocked Harry further was the fact that the teeth had a phoenix wing on it as he looked to the hilt and noticed his thunderbolt sign was mixed with a Lion and a Phoenix wing a well.

Thoughts ran through Harry's head as he looked to the Keyblade in question. Was this a sword… or a key but judging by its size and built it was a little of both. As Harry looked to it he noticed engravings on the blades shaft as he began to ready them. "Lions Burning Courage?" He read aloud as it made sense, lions were courageous creatures and the phoenix mixed in brought out the fire part. He then looked to the thunder bolt and figured it was something akin to himself.

"Keyblade? Lions Burning Courage." Harry said as he admired this weapon… but first he needed to get out of the medical ward and figure out what had happened but judging by this scene it seems that everything was going back to normal as the stress in the air had seemingly vanished somehow.

ESKK: Yes I know this chapter was short but it's mainly as an open salvo for what is to come. Anyway please leave a review before leaving and like always ja-ne.

ESKK: By the way if anyone is interested in co-writing this story all I ask is that you are in depth on Harry Potter stuff and Kingdom Hearts as this will hopefully move into the Kingdom Hearts universe when the time comes in time for Kingdom Hearts III's release.
