Hello Darkness My Old Friend

Thick black smoke began gathering in one spot in front of Dumbledore, afterward revealing a boy with a strange mark on his forehead. An expert in Dark Magic can easily guess that the mark resembles the exact wand waving of the killing curse, Avada Kedavra.

"Hello, Dumbledore" Harry, who appeared in front, called Dumbledore by his name, showing that he has no respect for Dumbledore.

"You have turned Dark, my boy" Dumbledore responded.

Hearing Dumbledore calling him boy, Harry waved his hand, causing the dark smoke around him to turn into a blade and launch toward Dumbledore.

Dumbledore merely cast a {Protego}, a magic shield, to block the attack.

"Do not call me boy… I am not your boy; I am no one's B-Boy" Harry furiously said.

Harry hates when others call him 'boy' as he has a trauma from Vernon, who likes to beat Harry and always refers to Harry as either a 'boy' or a 'freak'

"Very well… Harry. I see you could control your Obscurus abilities…" Dumbledore said.

Dumbledore is extremely familiar with the symptoms of Obscurus, as his sister Ariana, who was sexually assaulted by a couple of muggle boys, became an Obscurial. But almost all the Obscurus couldn't control their magic, causing them to explode or slowly die.

Dumbledore only knew one person who could control their Obscurus like Harry; he was Credence Barebone, son of his brother.

It was the first time Harry heard the word 'Obscurus,' so he gave a dubious look towards Dumbledore.

Dumbledore, noticing Harry's look, replied "Those powers of yours… is a type of powerful magical parasite that develops when a wizard or witch suppresses their magical abilities. The particular magic/creature is called Obscurus, and you are called an Obscurial for hosting that."

Harry's eyes widened; he thought his powers were unique, and they were only accessible only to him. As they have protected him and are the reason, he is alive.

"Though you are a unique case, Harry… Usually, an Obscurial will slowly die from not being able to contain the power of Obscurus. But you are special. I sense… it is protecting you. It seems the blood magic used by Lily mutated it and turned it into a guardian." Dumbledore said, causing Harry to relax and smirk. He has learned crucial information from Dumbledore, which relieves his worries about the mysterious power he holds.

"Fascinating, such a case could never happen, as the Obscurus would devour the unknown magic." With his Mage Sight, Dumbledore can see the Obscurus is protecting Harry, surrounding him in a cocoon. He can also sense the magic in Harry is sensing him as a threat.

Decided it was enough time for chit-chat, Harry raised both his hands and turned into a massive cloud of smoke.

Dumbledore then cast a magic bubble around him and said "Though that is the case… your body wouldn't be able to handle it. You will explode, and anything which can heighten your emotions will only increase the time… I beseech you, Harry, this is not what your parents would have wanted. I can help you, but you must leave your dark path."

"I WILL KILL YOU FROM MY SUFFERING" came a deep, almost demonic voice from the cloud of smoke.

"I don't know what happened with Vernon Dudley and your aunt Petunia. But, please, Harry, I will take care of you… and justic-" Dumbledore was interrupted when Harry, in his Obscurial form, turned into a snake and attacked Dumbledore.

The bubble blocked the attack, but there were cracks on the shield. Looked like it can only take one more hit of the same attack.

"So be it" Dumbledore said, prepared to attack.

Dumbledore has been reasoning with Harry to try to change him. He felt guilty about what happened to Harry, as he knew the process of becoming an Obscurial.

Kids who grew up in abusive households are known to become Obscurial. But, of course, an Obscurus wouldn't form just like that. Instead, a magic person would need to suppress their magical ability with fear of magic. So most magical kids who are forcibly suppressed by either their parents or their guardian will develop an Obscurus.

The textbook definition would be -When a magical child was forced to repress their talent through physical or psychological abuse, they developed a parasitical magical force inside them called an Obscurus.

This definition was changed through the course of wizarding history, as there was much to discover about Obscurus. Like how could a malicious dark creature gain sentience, how can a soul be formed just by feeding negative emotions, and how is its process similar to Dementors?

Dumbledore wanted Harry to be humble, naïve, and have no knowledge of the magical world. So he made sure Harry would grow up in a strict household, knowing Vernon and his Aunt Petunia. But he never thought Harry's relatives would abuse him.

Vernon and Petunia would have faced Dumbledore's wrath if he got a clue or a hint of their abuse.

Magical children are known to be treated with care because they are rare. When a witch and wizard couplet, they rarely get children, as it takes a tremendous amount of luck and magic.

That is why many squids were treated harshly, as they were the nightmares and 'failures' of their parent's expectations.

Dumbledore treated Lily as his granddaughter. With Lily's genius brain and charming personality, it wasn't hard for Dumbledore to like her.

So It was heartbreaking to see Harry turning dark, her son. He thought after making friends, Harry would change. With guilt-ridden, as ashamed to say, he ignored Harry after coming to Hogwarts.

Maybe his mind was making excuses and knew that he was the reason Harry turned into this. But unfortunately, there is no medicine for regret, and he just needs to take responsibility, hoping Lily and James will forgive him when he goes on his next adventure.

A stream of fire came out of Dumbledore's wand, shaping into a circle, blocking its exits and trapping him.

If Asura were here, he would have definitely recognized that Dumbledore, a 'white' wizard, is using the cursed fire {Fiendfyre}; enchanted flames capable of destroying nearly anything in its path.

When the fire made contact with the Obscurus, a high-pitched piercing sound came out of the cloud of smoke.

*Cough* *cough* Dumbledore suddenly started coughing.

"Oh dear… it looks like my time is near… my next grand adventure" Dumbledore said out loud, looking at the blood in his hand, which he had just coughed.

"Harry… Listen to me. I will not ask for forgiveness, but I implore you to reconsider. Forgive me for placing you with the Dursleys-"

"SHUT UP" a harsh shrill came from the Obscurus, interrupting Dumbledore's speech.

Dumbledore knew that he couldn't stop an Obscurus as there is no way to stop one other than to kill the Obscurial, its host. He couldn't possibly kill Harry; he doesn't have in his heart to kill Harry.

Even if he was pushed that far, he is not in his prime. And currently, he is suffering from a magical curse, so he has no way of stopping Harry without causing his curse to progress more.

So the only other way to stop Harry is to reason with him. An Obscurial could possibly be healed by replacing their feelings.

"YOU ARE THE REASON FOR MY SUFFERING" Harry spoke again with a deep voice.

Dumbledore knew that Harry, currently in Obscurial form, was unstable, so no matter what he said Harry wouldn't change.

"So be it" Dumbledore said as a stream of blue light came out of his wand and started to freeze all the smoke.

"{Fire}" said Harry. Then a large gust of fire came and melted the ice.

Harry then shaped the smoke into multiple large, sharp blades and painted them toward Albus.

*Screech*

Fawkes suddenly teleported and teleported him away from the attack.

"Right on time, Fawkes" Dumbledore thanked his companion Fawkes who teleported him away from the attack.

Harry's attack left many large scratch marks on the wall behind them. That force of that attack could slice a troll into half even with its magical resistant skin.

Fawkes replied with another screech, in the way of telling Dumbledore he would do anything for him.

Though the poor bird didn't realize he had lied unknowingly; as Fawkes had long fallen in Asura's grasp.

Soon, the battle between Dumbledore and Harry started. There were many spells, ranging from simple levitation charm to deadly fire summoned from Dumbledore's wand.

Harry, still a cloud of smoke, simply used brute force to attack Dumbledore. Harry used the surroundings to his advantage, throwing large objects and suffocating Dumbledore with his smoke.

Dumbledore simply teleported away using the phoenix, which can teleport anywhere unrestricted.

Harry had tried everything, and if it weren't for Dumbledore showing a sigh of exhaustion, he would have thought he was being toyed with.

"You are getting tired, Dumbledore… Your end is near!" Harry said by crazily laughing, seeing Dumbledore coughing blood.

Fawkes, Dumbledore's phoenix companion, could not help in any way as Dumbledore's illness is a magical curse, the highest level.

"*chuckle* Yes, Harry. This curse was the beginning of everything… and end of my life" Dumbledore replied while still maintaining his grandfatherly smile yet with more wrinkles and beads of sweat dripping from his forehead.

The curse Dumbledore held started his career, where he became the defeater of the Greatest Dark Wizard, the Leader of Light, the next Merlin. But at the same time, it was the reason for his career to end.

Harry, who was getting cocky, humored him

"So what gave the Great Albus Dumbledore, the defeated Dark wizards, the curse?"
