Chapter 8

(Last Time)

(On the Island of Azkaban)

The large prison of Azkaban was silent perhaps for the first time since it was built there was no sound, there was no wailing and moaning from prisoners there was just nothing. The reason for that would be obvious if you were to take a step inside the dark forbidding building, because if you did you would see the pale slumped over bodies of prisoners and guards alike. The cold bodies all shared one thing in common, and that was despite their lack of movement and their death like appearance they were all still alive. Or at least alive as one can be without a soul.

In a the main chamber of Azkaban a room that was usually used by the human guards to eat in, which was why it was warmer and could almost be considered cosy compared to the harshness of the rest of the prison. Within that chamber there were a number of beings some of them were human or close to human, an example being of a tall voluptuous dark haired woman who was wearing rather revealing clothes and who had a pair of black cat ears on her head. There were almost fifty of these people most of who were looking around the place they found themselves in with uncomfortable expressions on their faces.

There were however other things lurking in the room, things that were not at all human. These things floated eerily off the floor their forms wrapped up in smoke like black cloaks, strange skeletal hands seemed to poke out of their cloaks grasping in the direction of the humans in the room. The most obvious thing about these creatures however was the aura they were emitting, an aura of cold cruel despair, an aura that to the surrounding humans seemed to suck the hope and happiness from all it touched.

Stood prominently before this eclectic group, there was a young girl dressed in a lolita maid outfit. As she looked over the inhabitants of the room the girl's emotionless grey eyes seemed to glow slightly and her lips began to twitch up into something that could almost be mistaken as a smile. "Prepare yourselves for we have been noticed."

(Now)

(With Harry)

With a flash of golden light Harry appeared on the roof of the Wizarding Prison of Azkaban his emerald green eyes narrowed in suspicion as he crouch slightly, his senses extended as he landed. Rossweisse appeared slightly behind him silently, a stern expression on her face as she took in her surroundings.

As Harry stood up, his attire shifted. The tailored black suit melting away to reveal a set of white plate armour with gold engraving running up and down it. Rossweisse to changed her clothing, as her grey business suit vanished, only to be replaced by her elegant Valkyrie armour.

"What is the plan my Lord?" Rossweisse asked as she noticed the pensive expression on Harry's face.

Harry didn't answer as he continued to glare around at his surroundings.

"My Lord?" Rossweisse asked again, her light blue eyes narrowing cautiously.

"Be careful Rossweisse, we are not alone." Harry finally replied as he looked into the surrounding darkness, his eyes flashing slightly as he caught sight of a wispy black cloak and heard a rattling breathe.

With a calm look on his face, Harry willed his energy to take on the form of a large great sword. A blade that Harry carried with incredible ease, as he held it in both hands, the large blade held diagonally in front of him, his eyes shifting left and right.

Rossweisse glanced at Harry at that, before she nodded, her hands lighting p with crackling magic as she too began to take notice of the black cloaked forms of the Dementors of Azkaban as they began to encircle the two of them.

Her breathe began to mist as more of them arrived, and her head began throbbing as she felt the creatures begin to try and invade her mind, they touch cold and cloying even though it was only mental.

"What are they?" She asked quietly, her eyes hardening as she saw that they were becoming more confident, slowly encroaching on them.

Harry glanced over to Rossweisse as she asked that. When he had been just Harry Potter, he would have called the Dementors monster, soul sucking demons. But now he knew better, now he had his full memories back and knew exactly what these creatures were. "They were human once." Harry replied, his tone solemn.

Rossweisse's eyes widened at that, her eyes flickering over to Harry as she dreaded to hear how he would answer her next question. "You say they were human… What are they now?"

"They are the creations of Trihexa. Mortals who in their arrogance thought they could tame the power of chaos. Instead of taming it though, they were consumed by it. They became the very antithesis of life and humanity. They feel no warmth, or joy or happiness; their lives are consumed by pain, hatred and an insatiable hunger. The souls of others can be a balm for their pain, even if only momentarily. But for those few seconds of peace, they would do anything, commit any depravity or sin, so consumed are they by their agonizing pain and insatiable hunger for relief from that agony." Harry replied, his tone grim as he looked at the hundreds of Dementors around him. Unlike Rossweisse though, who could only see Dementors as black cloaked wraith like beings, Harry could see what they truly looked like.

What Harry saw was a twisted and a deformed monstrosity, each one of them looked different, their bodies and limbs twisted and warped, their sin was slimy and covered in boils and sores. One thing they all had though was a large lamprey like mouth, a gaping more filled with rings of small rotting teeth. And those mouths were all open as they continuous shrieked and screamed, their voices eternally filled with agony, as they suffered through life.

"How horrible." Rossweisse replied, her voice thick with emotion as she looked around at the hundreds of cloaked figures.

"Don't pity them Rossweisse, they brought this torture on themselves." Harry replied coldly. "They attempted to interact with forces that should never see the light of day. A force that has been bound for millennia and for good reason, in their arrogance and greed they attempted to unseal a creature that…" Harry didn't get to finish that sentence, as the Dementors had chosen that moment to attack.

The black shrouded figures unable to hold themselves back, despite the danger they could feel rolling off of the two figures, and despite the commands of their new mistress. The hunger was to great, and their pain too consuming.

Lashing out as he saw them coming, Harry swung his sword round, the blade covered in golden fire as he sheared through the three closest Dementors. Harry then followed that up by transfiguring the surrounding prison, massive stone spikes exploding from the walls, creating a forest of deadly stone that spitted and impaled the charging Dementors. Dementors may be immune to physical damage permanently hurting them, but that didn't stop it from temporarily hurting them and stalling them.

Taking a deep Harry then exhaled a massive stream of golden fire from his mouth, an act that was almost draconic in nature as the fire streamed from his mouth before it bathed the shrieking Dementors in fire. Destroying not only their physical form but also their souls as Harry's fire ate away at their very being.

As this was going on, Rossweisse had not been idle, where Harry had acted offensively though. Going straight on the attack, with sword and divine fire, she had instead remained defensive. Creating a large opaque shield that covered Harry's back as he took on the brunt of the Dementors with one hand, as her other hand alternated between throwing bolts of lightning, spears of ice or blast of fire.

Thrusting his hand out, Harry froze all the Dementors, paralyzing them with a powerful telekinetic attack. Slowly Harry began to clench his hands, an action that caused the Dementors to let out louder shrieks as they were slowly compacted.

Raising his other hand, Harry began to summon the frozen Dementors, clumping them together in a big ball of shrieking black cloaked beings.

"Rossweisse get back this is going to be pretty explosive." Harry called out as a small orb of roiling golden fire began to form between his two outstretched hands. The orb slowly began to get bigger and bigger, and as it did so it began to exude more and more heat, so much that the ground beneath where they were standing began to crack and melt.

Within a minute what Harry was creating between his outstretched hands became obvious. He had created a miniature sun, something that had enough power contained and condensed within it to probably destroy Britain entirely.

And Harry threw it.

Rossweisse could only look on her eyes wide, as Harry threw what looked like the sun, at the clump of trapped Dementors, all of them shrieking and struggling to break free of Harry's control.

They failed.

The only sound that could be heard was the shrieking of the Dementors getting louder and louder as the miniature sun first hit them, disintegrating anything it touched as it quickly burrowed its way within the clump of Dementors before suddenly imploding. Dragging the surrounding Dementors into a fiery maelstrom of death, leaving behind nothing but dust and the faint echo of the Dementors last few cries.

Nodding his head in contentment ~Harry then turned to a shocked and awed Rossweisse, the slightest of grins playing at his lips. "Dementors, terribly deadly against mortals and lesser supernaturals, but they were nothing compared to god level beings."

"Forgive me my Lord, but was that not overkill?" The silver haired Valkyrie question as she looked over to Harry.

"It worked didn't it." Harry replied with a nonchalant shrug. "Now come on, these were just the foot soldiers; there are much darker things now in this prison than the Dementors."

With that said Harry began to walk deeper into the dungeons, his great sword resting against this shoulder as he spread his senses out. He could feel the Excalibur shard further in the prison, muted though it was. A part of Harry wanted to believe that the reason for him being able to sense it was due to his own abilities far overwhelming the caster of the cloaking spell. Unfortunately though Harry knew that this wasn't the case, he would recognise the magical signature anywhere. The one cloaking the Excalibur piece was Ophis, and his older sister was far powerful and skilled, so much so that she could easily hide things from Harry or Great Red if she wanted.

This led Harry to the conclusion that he was purposefully being allowed to sense the Excalibur shard, and that he was walking into a trap. What kind of trap he wasn't sure yet, Ophis had always been a capricious primordial. Doing whatever she wanted whenever she wanted, so for all Harry knew, she could be luring him here to kill him, or she could just have an itch that she wants Harry to scratch, so she was luring him here for a good fucking. He honestly didn't know.

"Keep close Rossweisse, we are going to make our way there on foot." Harry said as he looked around him, a part of him wishing that he had recruited some Seraphs to come with him. As he didn't know what things his older sister had been up to in his absence, or who she had manipulated or threatened into fighting for her.

Rossweisse nodded at that, her hands still crackling with magic as she began to follow Harry through the dark and gloomy halls of Azkaban. The both of them staying alert as they stepped over the occasional dead guard or prisoner as they quickly made their way deeper into the depths Azkaban prison.

(With Ophis)

"My Lady." Cao Cao spoke up; his dark eyes cautious as he gained the attention of the powerful being before him, not at all underestimating her titanic strength or absolute ruthlessness as others had, tricked as they were by her young and innocent appearance. "The two hundred Dementors you had as sentries have been destroyed. Someone powerful has arrived; he killed them all in a matter of minutes."

A very faint smile tugged at Ophis's mouth as she heard this. Her usually impassive face showing the first trace of emotion any of the three dozen members of the Khaos Brigade, a group created by Ophis, had ever seen.

"Yes." Ophis said softly, her voice being heard by all of the men and women in the room. "I knew he would come, all he needed was an invitation and then some confrontation,"

"Who is he?" Cao Cao asked his tone slightly strained as he heard Ophis's vague reply.

"That does not concern you." Ophis replied as her dull grey eyes locked on Cao Cao. "You have a Scared Gear do you not?"

"Yes." Cao Cao replied arrogantly a prideful expression on his face as he continued talking. "I wield the most powerful Scared Gear of all; my spear can kill even gods and can…"

"Then you will return to base." Ophis cut in her tone bland as she looked at Cao Cao, with an unimpressed look. "Everyone with a Scared Gear will return to base." She added to the room as a whole, gaining a number of shocked and befuddled looks from the other members of the Khaos Brigade.

"What do you mean!?" Cao Cao demanded his face contorting in outrage.

"You are currently an asset." Ophis replied as she looked over to Cao Cao, knowing for a fact that if he was to face Harry that he would be stripped of his Sacred Gear and of any use he might have to her. "If you were to face the man that is coming you would be made useless to me."

"You doubt me?" Cao Cao sneered.

"The last time I met this man we fought. It ended in a draw." Ophis replied her tone completely emotionless as she just stated facts. "If you were to fight me, I would destroy you with ease. So to could this man, he would crush you with ease; he would not even consider you a threat."

"With my Sacred Gear he wouldn't…" Cao Cao began, before he was once again cut off mid speech, only this time due to a portal appearing under his feet.

With a cry out outrage Cao Cao vanished from the room, followed by another thirty members of the Khaos Brigade that had accompanied her to Azkaban. Several more portals appeared, dragging in the Dementors and a number of other members.

Within a matter of minutes the chamber was empty of everyone save for Ophis and a tall bespectacled blonde man, who was carrying a large sword.

"Why did you send everyone away my Lady?" Arthur, the blonde man spoke up as he realised that only he and Ophis remained.

"Because they were not necessary for what is to come." Ophis answered, not even looking at Arthur as she instead focused on the entrance to the room.

With a loud crash, the double doors burst open and two people entered.

"Hello Harry Potter." Ophis said her eyes shifting colour momentarily as a green eyed man with wild black hair entered the room, an armoured silver haired woman walking in behind him.

( - )

Entering the chamber through a set of double doors, Harry soon found himself facing a bespectacled blonde man n his early twenties, and a young looking girl in a gothic, lolita maid's outfit.

As he entered the room, sword in hand and Rossweisse dutifully following after him, Harry prepared to speak only to be beaten to the finish line by Ophis, as she spoke up first.

"Hello Harry Potter."

Harry froze at that, not sure how he should react to Ophis knowing the name he had as a human. Taking a second to gather himself, Harry forced a smile on his face as he pretended to lower his guard.

"Ophis, it's been a while how are things?"

"I know why you are here." Ophis replied, her face still blank and expressionless.

"Of course you do, do I really need an excuse to see my dear older sister?" Harry replied, ignoring the hitch in Rossweisse's breath or the sudden widening of the blonde man's eyes as he said that. Instead Harry focused on the long sword that the blonde man was carrying, Excalibur Ruler.

"Did you know I was here?" Ophis questioned blandly.

"Of course I did." Harry replied with a shrug. "Why do you think I came personally, I knew someone was cloaking the Excalibur shard and you were the most likely culprit. The big question here is why the fuck are you here?"

Ophis merely blinked at that, before the very slightest of smiles crept onto her face. "To see you."

"And why would you want to see me. The last I recall we did not get along that well?" Harry questioned as he subtly began to gather his power. Ophis was very unpredictable, and he refused to be caught off guard by her.

"I want you to help me." Ophis stated calmly.

"Help you with what?" Harry questioned cautiously, and why would I help you.

"I want you to help me deal with our brother." She replied.

"Depends really on which brother you're talking about?" Harry questioned as he continued gathering his power. He knew that at the moment if he were to take Ophis on, one on one that he would lose. His body was still not able to fully handle his power, which is not to say that he didn't think he could defeat her if need be. He had a secret weapon after all, he had God's Thunder, not that he was planning on using it anytime soon. Such a thing would destroy Britain and alert every single supernatural in the world of his continued existence, this would be inconvenient for Harry at this stage.

"Our eldest brother, he seems to have decided that he wants to live in the Dimensional Void, in my realm." Ophis replied a flash of irritation crossing her face.

"So fucking what?" Harry asked. "You want to team up and make him go away?"

"Yes… that or kill him." Ophis replied with a shrug.

"And why would you think that I would be stupid enough to help you piss off our brother. You know the most powerful of us, the Lord of Time and Fate, a being that can shatter worlds with just a thought?" Harry replied incredulously as he stared at Ophis as if he was questioning her sanity. He had just had his arse kicked by Great Red not that long ago, he knew for a fact that as he was he didn't stand a chance, even if he did have Ophis's help. He also knew that his older brother was a vengeful fucker who could hold a grudge for millennia.

"If you assist me I will assist you." Ophis replied with a nonchalant shrug. "All I want is him out of my home."

"How would you assist me?" Harry questioned cautiously.

"By giving you what you want." Ophis said.

"And what do I want?" Harry asked deciding to humour his sister for now.

In response Ophis raised her hand into the air, before swiping it sideways.

Rossweisse blinked in confusion as she saw that gesture, a questioning look on her face as she looked to Harry.

Harry though just looked very cautiously at Ophis, before his eyes trailed over to the bespectacled blonde man.

Seeing that Harry was looking at him, the blonde man made to speak. Only for his words to come out as a gurgle, a look of confusion crossing his face as his head fell off his shoulders, his face forever frozen in a look of shock, even as he died right then and there.

With a clatter his sword, Excalibur Ruler fell from his limp hand, the rest of his body following as it collapsed to the ground, like a puppet with its strings cut.

"He was you ally." Harry commented lightly, still surprised by Ophis's actions.

Ophis blinked at that in confusion before replying. "He was an asset. " Then with a flick of her fingers the holy sword rose into the air before it shot at Harry, handle first.

Snapping out his hand Harry caught the blade, a curious look on his face as he examined it, determining it was the real thing before making it disappearing in a flash of golden light as he stored it away.

"Did he really have to die?" Harry questioned.

"He was an asset because of the sword. Without the sword he is nothing." Ophis emotionlessly responded. "You wanted the sword so I gave it to you. I traded a lesser asset for a greater asset."

"You think because you murdered you ally and gave me a sword that was mine to begin with, that I would help you?" Harry asked his voice once again incredulous.

"That was a gift." Ophis replied nonchalantly. "If you assist me you will receive other things you want."

"Such as?" Harry questioned taking a slight step to his side, partially shielding Rossweisse as he did so. This is what he had meant by unpredictable, and he would be damned before he let Rossweisse be hurt by his psychotic sister if he rejected whatever it was she was offering.

"I will give you three Longinus's and twenty nine other Sacred Gears that I have collected, it is equivalent exchange is it not, I sacrifice lesser assets to gain a greater asset." Ophis replied, "As well as the location of a number of other Sacred Gears you have unleashed onto the world."

Harry's eyes widened at that, it appeared his sister hadn't changed a bit. She was more than willing to sell out half of her followers if it meant getting his aid. She was always pragmatic and emotionally desensitized when it came to things like this.

"I will also extend my help in dealing with our other brother." Ophis added on, her grey eyed gaze boring into Harry's emerald eyes.

Harry took a moment to process that, it appeared that Ophis like Great Red knew something he didn't. The deal she offered was a good one, but one that he would still need to think about as one did not simply piss off the Great Red for no reason. "From what I heard you are the one who is looking to release him in the first place?"

Ophis didn't even blink when she heard the accusation in Harry's tone. "And who told you that?"

"I have my sources." Harry replied sharply, his eyes fixed on his emotionless older sister, watching her for even the slightest sign that might tell him what she is up to.

"I want silence. I want to return to the Dimensional Gap, nothing more." Ophis replied in her monotone voice. "What would I gain from awakening Trihexa?"

Harry didn't reply to that, mainly because he didn't know what she was up to. Nor did he know what Great Red was up to. Things were far more complicated than he thought.

"So do we have a deal?" Ophis asked once more, her empty gaze moving from Harry to Rossweisse before slowly moving back to her younger brother.

"And what makes you think that I would accept that. Like you said, the Sacred Gears are mine; I am more than capable of tracking them down myself." Harry said moving onto a topic he was more comfortable with. Trihexa and anything to do with that monster was complicated, especially when it came to deal with his older brother and sister as well.

"Yes you are, unless someone was cloaking them with their magic." Ophis responded sharply not at all bothered by Harry's change of tack, once again a small smile playing across her lips as she spoke.

Harry narrowed his eyes at that. "I will think about it."

"Good." Ophis said her face once again blank. "When you reach a decision, you will tell me Harry Potter."

Harry made to respond in a noncommittal way, before he froze as he once again heard Ophis calling him Harry Potter.

"Tell me Ophis, how do you know the name Harry Potter?" Harry asked cautiously.

"Because that was the name you went by when you were human." Ophis replied with a shrug.

"And how would you know that?" Harry questioned.

"I was one of Harry Potter's friends of course. When I found you I wanted you to assist me in getting Great Red to leave the Dimensional Gap. So I befriended you, and nudged you towards the Deathly Hallows, the way in which you would recover you power." Ophis replied blandly as if she was discussing something as simple as the weather, instead of admitting to have manipulated Harry into finding the Deathly Hallows and regaining his power and his memories.

More than that it was shocking to find out that not only had his sister found him. But she had managed to get close enough to him to manipulate him, all without him knowing. He had always known his sister was devious, but he had never expected this.

"Who were you?" Harry demanded, racking his brain as he tried to think about just who she had pretended to be and how she had manipulated him, knowing Ophis she could have been male or female.

Ophis didn't reply to his demands though, instead she just gave him that same very small smile as a portal appeared beneath her feet. Her grey eyed gaze locked on Harry as she disappeared. "Remember to tell me when you come to a decision."

Within moments she was gone, leaving an armed and armoured Harry and Rossweisse standing alone in an empty chamber. The two of them the only living things on the Island of Azkaban after Ophis's impromptu visit to the island, meeting with Harry and recruitment of the Dementors.

Harry stared silently at the spot where Ophis had disappeared, his eyes narrowed as he tried to comprehend what game she was playing.

"My Lord what should we do?" Rossweisse asked Harry cautiously, her gaze flicking form Harry to the headless body of Arthur, the former wielder of Excalibur Ruler.

"You go back to Heaven." Harry decided having come to a decision. "Gather the pieces of Excalibur I believe it is time for that blade to be re-forged and bestowed upon a new champion. Also keep an eye on Kuoh and the Devil influence there. Also make sure to keep track of Kokabiel, I want to know what he is up to."

As Harry rattled off his order Rossweisse nodded along, committing what he said to memory as she prepared to teleport back to Heaven. Before she did however she paused. "What will you be doing my Lord?"

Harry blinked at that before he looked at the great sword he was still carrying, absentmindedly absorbing the divine energy it was made form as he caused it to dissemble.

"I will be going to Atlantis to meet up with Poseidon. I think I am going to need a symbol of power if I am to stand up to my siblings as I am now, and who better to make me one than the Elder Cyclops, the ones who forged Zeus's Bolt of Lightning and Poseidon's Trident." Harry said his mind whirling as he thought about the information he had just been given. Things were far more complicated than he had thought. Things were slowly spiraling into chaos, and not just with the Biblical Factions, and Harry knew and dreaded what would come from that chaos.

(Somewhere Unknown)

In a humongous chamber of marble, a figure stirred, a pair of corrosive yellow eyes opened. Shifting slightly in the throne like chair it was seated in, the being looked down at the dozens of robed figures in front of it, each of them kneeling down their heads lowered in reverence.

Eyes gleaming with barely contained malice and glee, the being said. "The time for change has nearly arrived."
