1st August 1982,

North Sea

Present on the horizon was a lone island. And surrounding it were cloaked beings floating around. For those approaching this island, the scenery was sure to take away the good feelings of their minds, replacing them with depressing thoughts and the flashbacks of their worst moments in life.

This was the wizard prison of Azkaban and the cloaked beings were the dementors, beings that lived and fed off on positive emotions and souls of humans. No one knew how they were created, but most believe that they should just be executed. But corruption ran rampant in this world and trying to exploit the dementors' power, the corrupt wizards, even if they couldn't fully control them had placed them as guards around the prison.

The only charm that could repel dementors is called a Patronus charm. It was made of positive emotions and could push a dementor away. But it was of no use in destroying them. The founders' researched extensively about the dementors' and were on the verge of a breakthrough but sadly they died before it happened and the research notes were lost.

But right now, one person has gained that knowledge and arrived at Azkaban. He would change the fate of the prisoners, the dementors' and the wizarding world starting this very day.

Flashback,

Harry Potter has arrived at this despicable place with an acquaintance named Severus Snape with the help of his new familiar, Fawkes the Phoenix. Acknowledged by the founders' themselves as a blood and magical heir to them, he gained knowledge of his heritage and even learnt several types of arts, previously thought to be lost during the break. He was also striving very hard to correct the way of the world he lived in though it is still not out in the open.

He had bonded with several magical species and also gained their trust and support in case of another war coming by. The latest of them was his newest familiar who flamed to him when he was just clearing out Privet drive, never to return again.

After he had returned to Privet drive, he was confronted by his uncle and aunt, who tried to lock him in his room and his trunk in the cupboard stating that they would not allow him to practice his 'freakishness' in their 'perfect home'.

But Harry proved to be smart. He didn't have the trace on two of his wands since they dated back to the founders' time and the one with the trace and was used in his school and was now locked in his trunk.

Whipping out his Snakewood wand, he transfigured Dudley into a pig, who had just come down from his room upon hearing the commotion. Petunia and Vernon were shocked to see the display of 'freakishness' in their house and their 'precious dudders' turned into an animal.

After getting over the shock, Vernon tried to hit Harry for using magic but Harry was faster. Using reflexes, he had gained from Quidditch, he sidestepped Vernon's punch and kicked him directly in the gut. With Vernon knocked out of his breath, he put him, Petunia and pig-Dudley under a body bind and started to speak.

"I have had enough of your shit. I honestly thought that you would leave me alone or at least take better care of me. I hadn't asked for any of this. I didn't ask for my parents to get themselves killed nor did I tell anyone to place me here nor did I ever ask for a dark wizard to come after me."

By now, tears were streaming down Harry's face. Repressed emotions for 11 years were surfacing. His sadness rapidly turning into anger.

"I just wanted you to love me. I would have given up everything in the world including my magic if you had just loved me or showed me affection. But you treated me like cheap labour. You got money from my vault yet you still called me a waste of space. If you are not so close minded about me, you could have still seen me as a normal human and not like a house elf. You could have at least given me some memories of my mother."

Harry was very angry by now and was leaking magic causing appliances in the house to go berserk. All the Dursleys were terrified right now witnessing his power, notably Petunia. Dudley and Vernon had already fainted.

Harry gripped his wand tightly and turned it onto the only conscious member of the Dursleys who was showing fear with a dash of regret in her enlarged eyes.

"I just wanted you to tell me that you would take care of me and love me. I hoped that you would get over the grudge about my mother and treated me as one of your own. But now I know that you still held onto it even after she died and will still do it even if she was never not at fault. If you had died leaving Dudley as an orphan, my mother would have treated him like a second son to her. But you would never do it. You would only care about yourself and your family even if the world is being destroyed."

"Hence, I have no choice but this." spoke Harry to which Petunia's eyes went wide in fear recognising that Harry is about to perform a ritual on her and her family.

Harry's eyes glazed and he waved his wand in a complicated motion while speaking the following words:

"I, Harry James Potter, scion and head of the Ancient and Noble House of Potter, do hereby proclaim that any ties between my aunt Petunia, her family and myself be terminated. Let the family known as Dursleys be punished for the wrongs they committed and this proclamation be forgotten. Let the Dursleys atone for the sins, they committed knowingly or unknowingly. Let them feel only apathy until the atonement is complete. If magic deems me unworthy of this, let the burden fall onto me and my magic be sealed away forever. So mote it be."

The moment Harry had completed the declaration a golden light erupted from Harry and enveloped the inhabitants of the house. After sometime, the light died down and Harry collapsed there, with his body wracked in pain and almost all of his magic reserves exhausted but still available for usage of magic which confirmed the ritual's success. The reason many didn't use rituals was that the rituals were magically and physically very exhausting. But Harry thought that the situation had called for it.

He observed that the male Dursleys were still unconscious and Petunia still awake but in a world of pain. The body bind charm on them had been broken when Harry had conducted the ritual.

Harry transfigured Dudley back into a human. Then he turned away and started to lug his trunk to his room slowly. On the stairs, he called out to Petunia who turned to face him after a lot of effort. She also held unshed tears in her eyes, either from the pain wracking her body or understanding Harry's pain a little too late. But Harry understood what she tried to imply.

"Don't even think about it Aunt Petunia. What I did is irreversible. Only after you and your family atone for your sins against me and others who you hurt unknowingly or knowingly can the curse, I placed on you be truly lifted. If you had just treated me with love and kindness instead of apathy and animosity, this situation would have never even arrived. You are to blame yourself for this."

"The curse wouldn't take effect until I leave which is in a month. You will not remember this incident by tomorrow nor anything about me. You will still supply me with food for the duration of my stay here. I will only stay here for just this summer. I will not come back again to disturb your 'perfect life' though I doubt that it lasts forever. Goodnight Aunt Petunia."

After speaking out his mind, he started to drag the trunk again. After a full strenuous half an hour, he finally reached his room and put the trunk aside, ready to be cleaned tomorrow. He was very tired today from his conversation with the 'family'. His last act for the night was opening Hedwig's cage and the window when he immediately flew off to which Harry was amused a little. Hedwig didn't like being cooped up for long. He was bit many times to assure that fact.

After that, he promptly collapsed onto his bed, the exhaustion finally hitting him fully. Untransfiguring Dudley took a larger toll on his now meagre reserves than he expected (or so he thought). Feeling the cool air from the window, he drifted to sleep where he had dreams of being free.

From that day, Harry's life was at its finest. He could do whatever he wanted and he got full meals which healed him nicely back to his peak form while his magical signature was being masked to prevent unnecessary intruders from intruding into the house. He also started exercising to keep his body fit. Just because the blood wards could protect him from harm didn't mean that they could protect him from others who had a twisted sense about protecting him.

When he examined the blood wards, Harry's magic and anger nearly exploded. The wards were a twisted abomination of what they called blood magic. It fed off his magic while blocking off any bonds he had. It also made him weak and if possible, even kill him. It renewed other magical cores of those who he assumed to be allies while eating away his own. His exhaustion after the ritual also made sense to him. His reserves were rather unusually large and didn't fade fast which is true.

They also seemed to warp his sense of right and wrong while negative tendencies like anger, hatred were in chance of increasing while ignoring his other emotions. Those wards are increasing his tendency about thoughts like revenge. There were also another set of wards present that influenced his decisions onto the point of completely obeying the creator's orders. The wards also seemingly took some of his reserve magic to add to the Ward's creator as well (which in this case is Dumbledore). If he stayed there for long, his mindset would shift into the ward creator's view and would follow it wholeheartedly without realising that their mindset is altered permanently.

All in all, the wards were a perfect device to control him or outright kill him. If news about these wards spread, the dark families would outright abuse the abilities of the wards. Not wanting to be controlled or be fed off his magic, he just, in turn, sucked out the magic from the wards harmful to him, leaving them intact but devoid of any magic. They too would fall when the 'blood wards' fell as well. He could share that magic with his friends and increase their reserves as well.

The magic absorption and its counterpart, the magic sharing techniques were derivatives of the technique Godric Gryffindor shared with the founders. Harry improved the techniques in addition to adding Hufflepuff's cleansing power to his techniques as well. Now he could suck magic out of harmful things, making them harmless while filtering it to become pure, ready to be added to his own reserves or to be shared. Dumbledore needs the elder wand to carry out these techniques but Harry can use them wandlessly.

July 1st 1992,

After a month, he was ready. The Dursleys completely ignored him while he checked around. After he was sure that the wards were fully loaded, he grabbed hold onto his belongings when Fawkes appeared in a blazing ball of fire. After Fawkes had explained Harry about who he was and about why he left Dumbledore, Harry had a few doubts. But Fawkes reassured him and even mentioned Sesha and his acceptance.

Harry was sceptical at first for a dark creature wouldn't interact with a pure one, especially a Phoenix but Fawkes told him that they were the guardians of the school. Some were purely dark like lethifolds, dementors, Basilisks, Acromantulas etc. But the acromantulas and Basilisks could interact with beings like the Phoenix, provided that they bond with a suitable wizard who can tame them and always uphold the goodwill of other living beings. Such persons were rare but Sesha was one of the lucky Basilisks having bonded with such one, rare person.

Fawkes also showed him the memories of Gryffindor and Slytherin who made them de-facto guardians of the school and their heirs. Since Harry also had those memories, he cross referenced them and after finding it true, accepted Fawkes's help and bonded with him. Together, they left the Dursleys to visit Severus Snape and then go to Potter manor where they could plan on how to break Sirius out.

After a month of planning (more like since the start of his schooling at Hogwarts), they were ready to break Sirius out. Harry had also planned to take some dementors out if they came anywhere near him otherwise, he'd leave them alone. After all, there was no need to provoke a beehive if the bees were not attacking him, right?

Once they touched down onto Azkaban's floor, the dementors' started to surround them, intent on consuming the new food which had ventured into their land without protection. Harry and Severus were starting to feel their effects and Harry sighed to himself. He didn't want to use his trump card yet but the dementors' were not supporting him in any way. Meanwhile the dementors' were only thinking about 'new food' not knowing that their end was near.

Harry whipped out his snakewood wand in his right and Rowan wand in his left hand. After studying about the dementors' and the Patronus charm, he had reviewed the knowledge from the founders' and finally had created a cure for the dementor problem. It took a lot out of him and only after practicing with a boggart in the manor and with Snape as well. Channelling his magic into both wands, he called out together with Snape who also had his main and spare wand out as well:

Expecto ignis custos

Expecto enim fulgur custos

From his snakewood wand, a phoenix patronus made of white-hot flames shot out while the Rowan wand created a blue thunderbird patronus while Snape created a fire and lightning doe patronus. All the 4 patronuses charged onto the dementors' and when they made contact, the dementors' started to shriek in pain and their cloaks began getting ripped off. Many tried to escape but the patronuses seemingly grew in sizes while splitting into various smaller patronuses.

Each of the smaller patronuses attacked an individual dementor. Soon many of them started to grow weaker and finally succumbed to the patronuses assault. Many of them containing holes in their chests, some having their heads ripped off while some disappeared into the patronuses mouths, never to be seen again.

While the dementors' were being slaughtered, their bodies started to disappear leaving small, blue spheres which ascended into the sky. And for the first time since dementors started guarding Azkaban, rays of sunlight started to break through the cloud cover, relighting Azkaban in direct sunlight for the first time in a thousand years. And after every Dementor in the region was destroyed, the patronuses dissipated, considering their jobs done and both Snape and Harry collapsed, more due to stress than due to magical exhaustion.
