Hogwarts: This holy light is righteously evil.

The decision was made quietly by the two of them during a break in the funeral procession, without informing anyone, and each had their own reasons.

Regulus proposed going to Azkaban with only one main purpose: to personally inform his brother Sirius Black, who was imprisoned there, of the death of their elder.

Regulus kept cursing Sirius, saying he was already dead and that he should just pretend he was dead, but he never actually believed that his brother was Voldemort's henchman who had killed so many people!

When Regulus told Puni his idea, he thought Puni would refuse.

After all, Azkaban is a place where serious criminals are imprisoned, with a gloomy and terrifying atmosphere. The existence of Dementors makes countless wizards hesitate to go there. Even though Puni had been there once, there was no need for him to make a special trip again.

To his surprise, Puni agreed almost without hesitation and offered to go to Azkaban with him.

What Regulus didn't know was that Puni's decision to go to Azkaban wasn't for Sirius, nor for the Lestrange brothers who were imprisoned there. Puni didn't care about the two brothers at all, and even secretly felt that it would be more in his interest if they died sooner.

After all, the Lestrange family and the Black family have many connections, so their passing would only benefit him, not harm him.

Let him truly become Lestrange's complete loner.

......

Azkaban, situated on a desolate island in the middle of the North Sea, is not a prison in the ordinary sense, but the most feared prison in the entire British wizarding world.

When wizards mention it, they always lower their voices, and an undisguised fear appears in their eyes.

This prison has a long history. It was originally just an isolated fortress at sea. Later, it was officially requisitioned by the Ministry of Magic and became a place to imprison British wizard criminals. Since then, it has witnessed the despair and cries of countless wizards.

To prevent Muggles from discovering the existence of this wizarding prison, the Ministry of Magic cast several specific concealment spells on Azkaban. These spells interact to not only completely hide the entire island and fortress from the sight of Muggles, but also prevent it from being mapped by any Muggle or wizard.

Whether it was a Muggle ship passing by by chance or a wizard trying to locate it with magic, no one could detect Azkaban's presence. It was as if it had never existed, quietly hidden in the vast ocean.

Upon entering Azkaban, one can feel the powerful force of magic; it is highly likely that a Threadless Stretch Charm or similar spatial expansion magic has been cast upon it.

From the outside, the fortress is not large in size, and even appears somewhat compact. However, the interior space is exceptionally vast, enough to accommodate all criminals in the UK who have violated wizarding laws. Even during the period when the number of criminals was at its peak, there was never a shortage of space.

This ingenious use of magic turned Azkaban into a seemingly small but actually boundless prison.

Unlike other prisons, Azkaban has no towering walls or strict magical barriers to prevent prisoners from escaping. Even the seawater barrier is hardly a true means of imprisonment.

Here, what truly traps prisoners is never external shackles, but their own hearts. Every prisoner imprisoned here is enveloped in endless despair, unable to evoke any thoughts of happiness in their minds. All the beautiful memories of the past are gradually swallowed up, leaving only deep-seated pain and numbness.

Almost all prisoners who entered Azkaban could not escape the fate of mental breakdown. Most of them would go completely insane after only a few weeks of imprisonment, either muttering to themselves all day long or falling into long periods of silence, completely losing their rationality as human beings.

The root cause of all this is the Dementors, the guardians of Azkaban.

Dementors are not normal creatures; they are non-existent entities and are recognized as dark creatures in the wizarding world. They are also considered by many to be the ugliest and most terrifying beings in the world.

They have no fixed form, shrouded in a layer of cold black mist, their figures are elusive, and they move without making a sound, like messengers from the darkness, bringing a chilling cold and endless despair wherever they go.

Their abilities are extremely bizarre and deadly. Their most prominent characteristic is that they suck out human happiness. As soon as a Dementor gets close, the people around it will instantly feel intense depression and despair. All joy, hope and beautiful memories will be sucked away little by little, leaving only deep-seated sadness and emptiness.

Even more terrifying is that Dementors can directly suck away a person's soul. Once a person's soul is sucked away, they become a walking corpse, without thoughts or emotions, just an empty shell that can never be restored. Therefore, Dementors are also known by wizards as "soul-stealing demons" and are the nightmare of all wizards.

This small island, hidden in the middle of the North Sea, has never appeared on any map of Muggles or wizards, and few wizards know its exact location except for the core members of the Ministry of Magic.

Its vast interior space is amplified entirely by the power of magic. Without the support of this spatial magic, this small island would be unable to accommodate the large number of criminals and Dementors.

Tracing its origins, Azkaban was not originally a prison, but rather an isolated fortress at sea, inhabited by an evil sorcerer who called himself Extis.

This wizard was cruel and loved killing. He often used magic to lure passing Muggle ships to this island, where he would then torture them in various ways until they died in agony.

Extis committed numerous evil deeds throughout his life, and ultimately died in a magical backlash.

With Extis's death, all the hidden spells he had cast on the fortress and the island during his lifetime also became ineffective.

It was only then that the Ministry of Magic accidentally discovered this small island hidden in the North Sea, and learned that there was such an evil wizard in the world who had committed countless heinous crimes here.

But the island was no longer the same as it had been in life. Because it had been shrouded in darkness for years, it had become a haven for a group of Dementors. They roamed freely, feeding on the remaining negative emotions, turning the island into a place of despair.

After the Ministry of Magic learned of the existence of Azkaban, some officials proposed destroying the fortress.

After all, the island not only retains the dark aura of the evil wizard Extis, but also gathers a large number of deadly Dementors, making it a major hidden danger in the wizarding world.

However, this proposal was ultimately not adopted, mainly due to the concerns of the Ministry of Magic. They worried that if the fortress were forcibly destroyed, the Dementors living on the island would be completely enraged and would launch a frenzied retaliation against the Ministry of Magic officials and even the entire wizarding world. In that case, the damage would far outweigh the risks of preserving the fortress.

For these reasons, the proposal to destroy Azkaban was completely shelved, and the island, filled with darkness and despair, was abandoned in the vast North Sea, forgotten and neglected for many years.

Occasionally, a wizard would accidentally wander into this sea, but he would only catch a glimpse of the island's outline before being frightened away by the chill and despair surrounding him. No one dared to actually set foot on this island occupied by Dementors.

It wasn't until the International Law of Secrecy came into effect and the order of the wizarding world was further regulated that the Ministry of Magic realized the importance of setting up a dedicated wizarding prison.

Prior to this, the Ministry of Magic had been using small wizarding prisons to hold criminals. However, these small prisons had many drawbacks. Prisoners who attempted to escape would often unintentionally release conspicuous magical lights, pungent magical smells, or make noisy noises during their escape, which were easily detected by Muggles. This seriously violated the provisions of international secrecy laws and caused a lot of trouble for the Ministry of Magic.

To address this problem, the Ministry of Magic began planning to build a dedicated wizarding prison in the remote and sparsely populated Hehidiri Islands. This prison would not only properly detain criminals but also prevent them from being discovered by Muggles, thus ensuring the strict enforcement of international secrecy laws.

After the plan was put on the agenda, the Ministry of Magic began to prepare for the relevant matters, and construction would begin when the time was right.

However, this plan took a turn one year. After Damocles was elected Minister of Magic, he immediately rejected the proposal to build a new prison on the Hehidari Islands and insisted on reopening Azkaban as the only wizarding prison in Britain.

In his view, Azkaban itself had the foundation to imprison criminals. More importantly, the Dementors on the island were born with a powerful deterrent force. If they were used as prison guards, not only would it save a lot of time, manpower and financial resources to build a new prison, but it would also be able to keep all criminals firmly in place with the Dementors' abilities, without having to spend extra effort to maintain order in the prison.

This proposal was met with opposition from some officials within the Ministry of Magic.

They believed that Dementors were evil, dark creatures, and using them as guards was too dangerous; if the Dementors went out of control, the consequences would be unimaginable.

However, Komcleslow remained resolute in his decision, and given that the proposal would indeed save the Ministry of Magic a significant amount of money, the plan to use Azkaban as a wizarding prison was ultimately implemented smoothly.

As it turned out, Damocles' decision was not without merit.

Since Azkaban was officially put into use, there have been almost no cases of prisoners escaping, nor have there been any incidents of prisoners violating international secrecy laws due to escapes.

The Dementors' intimidating presence completely deterred every prisoner imprisoned there from escaping, allowing Azkaban to firmly establish itself in the wizarding world and consistently play a central role in the wizarding prison system.

Over time, Azkaban gradually became the most intimidating force in the wizarding world. Its name, like an invisible shackle, constantly reminded every wizard not to take risks and break wizarding laws.

Being imprisoned in Azkaban means enduring endless despair and torture, with no chance of ever regaining freedom.

Even wizards who had only seen Dementors from afar knew how terrifying these dark creatures were.

They all knew that without the protection of the Patronus Charm, simply standing next to a Dementor would lead to being swallowed by endless despair; that deep-seated emptiness and sorrow was enough to destroy a person's will.

Therefore, all wizards keep their distance from Dementors, let alone being imprisoned in Azkaban, which is almost every wizard's worst nightmare.

But there are always exceptions. Now, there is one person who is not afraid of the despair of Azkaban and the threat of the Dementors. On the contrary, he is full of anticipation for this trip to Azkaban.

This person was Puni.

Unlike other wizards who feared Azkaban, he felt no fear whatsoever; on the contrary, he was overjoyed.

Because he didn't know if the diary would develop any new abilities during this trip to Azkaban.

What if there is?

Azkaban has extremely strict visitation rules, and not just anyone is qualified to enter the prison to visit criminals.

According to the Ministry of Magic's regulations, only high-ranking officials of the Ministry of Magic have the right to enter Azkaban to visit their relatives who are imprisoned there.

The most typical example is Barty Crouch Sr., who held a prominent position and wielded great power in the Ministry of Magic.

Therefore, he and his wife were only allowed to enter Azkaban to see their son one last time as he lay dying.

However, such a situation is extremely rare.

After all, there are not many high-ranking officials in the Ministry of Magic, and among these officials, very few have relatives imprisoned in Azkaban.

Therefore, this right of visitation is mostly used by the Minister of Magic to inspect Azkaban. The Minister needs to go to Azkaban regularly to check the prison's security, understand the prisoners' conditions, and ensure the prison's stability.

Of course, as the highest authority in the Ministry of Magic, Cornelius Fudge possessed far more authority than other officials.

In addition to his regular inspection rights, he also had the autonomy to appoint additional personnel to visit Azkaban without the approval of other officials.

Moreover, he could summon Dementors from Azkaban, using these dark creatures as his personal guards, and using their intimidating power to deter anyone who tried to harm him.

However, using Dementors as guards also has significant drawbacks.

Wherever Dementors go, they bring a chilling atmosphere and an air of despair. No wizard or Muggle is willing to approach someone surrounded by Dementors, which makes Cornelius Fudge always feel lonely and isolated, with no one close to him.

More importantly, in order to resist the Dementors' aura of despair, he must constantly cast the Patronus Charm. Once the spell is interrupted, he will be drained of his happiness by the Dementors and fall into endless despair, which is also a considerable burden for him.

Regulus had made a prior agreement with Minister of Magic Cornelius Fudge, promising to publicly agree with the Daily Prophet's reporting stance and clarify that the previous attack on Black Manor had nothing to do with Voldemort.

It was this promise that made Fudge put aside his concerns and finally agree to allow Regulus to visit Sirius in Azkaban, while also tacitly allowing Puni to go with him.

After the permission was granted, a group of wizards dressed in Ministry of Magic uniforms came to meet the two.

Instead of choosing conventional means of transportation, they employed a series of convoluted and bizarre magical methods, sometimes using Apparition, sometimes using magic to obscure the two's vision, and changing routes multiple times along the way. They remained heavily guarded throughout and did not reveal any information about Azkaban's location.

After all, Azkaban's exact coordinates are a top secret in the wizarding world, and their leakage could lead to unpredictable dangers, so the Ministry of Magic has always been extremely cautious about them.

After countless transfers, the two were finally brought to the shore of the island where Azkaban was located.

The moment I set foot on the island, a bone-chilling cold swept over me, mixed with an intense atmosphere of despair that chilled me to the bone.

In contrast, the wizards from the Ministry of Magic who came to meet them were in far worse condition than Regulus and Puni.

Their faces were pale, their eyes were unfocused, their steps were unsteady, and some even trembled slightly. They had long been deeply affected by the atmosphere on the island and had lost the composure they had when they arrived.

The leading Ministry of Magic official, forcing himself to stand, bowed slightly to Regulus, his expression a mixture of apology and barely concealed exhaustion: "I'm so sorry, Mr. Black, but due to the influence of the Dementors, apart from the prisoners, no other wizards usually stay on this island. Even those of us who came temporarily to meet them are finding it difficult to adapt to the environment here."

Puni looked around and, sure enough, did not see any wizard guards.

He instantly understood that the reason Azkaban had never experienced an escape was not due to its tight security, but rather to the multiple natural and magical barriers it possessed.

This place is enchanted to prevent apparition, making it impossible to escape instantly through magic.

Its location cannot be marked on a map, and even a skilled wizard would find it difficult to locate it on their own.

In addition, the island is teeming with Dementors, whose intimidating presence is enough to deter any prisoner attempting to escape.

These three safeguards made Azkaban an inescapable prison.

After catching their breath, the wizards from the Ministry of Magic eagerly raised their wands and began chanting Patronus Charms.

In a place like Azkaban, not summoning a Patronus means facing the despairing aura of Dementors, having your happiness drained day after day, no different from being a prisoner. No one wants to endure such torment.

Warm rays of light rose from the tips of their wands, and guardian spirits of various forms appeared, dispelling some of the chill and despair around them and slightly improving their condition.

On the other side, Regulus stood still, his expression also somewhat solemn, clearly affected by the atmosphere on the island, feeling particularly uneasy.

Seeing that the wizards from the Ministry of Magic around him had all summoned their Patronus, he no longer hesitated. He slowly raised his wand, took a deep breath, and clearly recited the incantation: "Patriot!"

As soon as he finished speaking, two warm beams of light burst forth from the tip of the wand, coalescing in the air to form two greyhounds, each more than half a person's height, with fluffy fur, sharp eyes, and radiating a soft yet firm light. They were the greyhound pattern engraved on the Black family crest, exuding an aura of majesty.

Unlike other wizards who have a single guardian spirit, Regulus's two greyhound guardian spirits huddled together, exuding a more imposing aura that instantly dispelled the despair surrounding him.

Regulus gently raised his chin at one of the greyhounds, gesturing for it to come to Puni's side and protect him.

After all, although Puni had been to Azkaban once before, he still couldn't help but feel a little worried.

After settling everything in, Regulus didn't linger. He headed straight for Azkaban prison with steady steps and without the slightest hesitation. He was eager to see Sirius and tell him about Alphad's death.
