Harry Potter: Dimensional Wizard

Edward sat on a desk writing a bunch of things, and each time he finished a page, he would place it on top of a pile at least 50 cm thick. What he wrote consisted of mathematical formulas, runes designing, and paragraphs of written words.

Once he finished, he sighed out loud. He took the pile of papers and flipped through it one last time.

"Beautiful," he muttered, looking at his work in the past 8 months. After setting up the secret magic array around the Academy, Palace, and Protection Hall, he did not immediately activate them since he wanted to study the Universe Will further to prevent any problems.

However, not long after his study, his Willpower reached the 5 scale, which was the minimum requirement to use Conceptual Magic in a weak universe such as the Black Clover World. But, he discovered something unique about this world after failing to force the Universe Will to grant him authority over Space-Time.

Merlin once explained to him that Tier 11 Multiversal Beings is a unique tier that some individuals often unintentionally skip. Reaching Tier 11 does not mean someone could destroy a multiverse. No, only Tier 12 individuals can destroy a multiverse, and there is a valid reason for that.

Reaching Tier 11 means that all the different versions of a person across the multiverse become one; they can access each other's power, memories, experiences, etc. And as long as one version of that person is alive in the multiverse, a Tier 11 entity cannot die.

In other words, to kill a Tier 11 entity, you have to erase all their counterparts or variants simultaneously. Otherwise, as long as one person survives, after a while, as they make more decisions or through other means, the single survivor will create an infinite number of themselves across the multiverse.

Here is where things get complicated. There is no way for a person to exist in every timeline across the multiverse, even if there is an infinite number of them. For example, there are many timelines in which Edward does not exist in the Harry Potter Universe.

So, as long as a Tier 11 powerhouse does not exist in every timeline, even if each of his variants across the multiverse had the power to destroy a universe (Tier 10), they cannot destroy the multiverse.

Edward understood that this involves the concept of smaller infinite and greater infinite. Tier 11 powerhouses have an infinite number of variants, but their infinite is smaller than the infinity of the entire universe–which contains the infinite timelines the Tier 11 powerhouse exists and the infinity they do not exist.

Universe=Greater Infinity, Tier 11=Smaller Infinity.

So, he theorized that the only truly perfect Tier 11 entity that exists across all infinite timelines/parallel dimensions is the Universe Will. Usually, a Universe Will is responsible for one timeline without the others interfering.

For example, when Edward tried to force the Universe Will to grant him the authority of Space and Time, he should have confronted the Universe Will in the current timeline; this is how most of them functioned.

However, the Black Clover World is unique since this Universe Will seemed capable of borrowing power to confront him. So, trying to confront the Universe's Will to wield Conceptual Magic was like fighting an infinite version of the Universal Will; well, maybe not an infinite number of them, but a few thousand if not a hundred thousand.

Edward theorized this anomaly was related to God, the Wizard Sage, and how it seems to split the Universe Will into three parts. Nevertheless, he did not care about this for now since he had more important things to worry about.

After discovering this anomaly, he had a brilliant plan to become a perfect Tier 11 Arcanist: use the Universe Will to spread all his variants/self across the entire multiverse. So, he would exist in every timeline in the multiverse. At Tier 11, by controlling all his variants across the infinite multiverse, he should be able to destroy it if he wishes.

Edward looked at the document on the table with a smile; he did not succeed yet as his research of the Universe Will and the Multiverse is still in its infancy. However, he had a basic theory to build upon in the future.

He destroyed the document after Morgana scanned it. Feeling the desire to eat something, he walked toward the cafeteria. It was late at night, so it was closed. However, Edward had special privileges, so he went inside to cook something to eat.

He found the ingredient and made udon noodles. After eating his lunch, he looked at the dark corner of the cafeteria: "Whoever you are, if you are a foe, please don't throw away your life pointlessly. If you are a friend, please state your intention."

"You are indeed as arrogant as the rumors."

"When you are capable, it's called confidence," Edward replied as he looked at the uninvited guess.

"The Divine Maiden?"

"You know me?"

"Is there someone in the dynasty who does not know you?" The Divine Maiden is known throughout the Dynasty, capable of divining spirit disasters as soon as they appeared, saving the lives of millions of people.

"I guess that's true."

"So, what do I owe this visit?"

The Divine Maiden suddenly knelt on the floor, "I need your help."

"I'm sure you are, but why would I help you?"

"I'm willing to offer my loyalty."

"Based on what happened to the Shogun recently, I doubt your loyalty means much," Edward replied. The Divine Maiden paused briefly before taking a short dagger and cutting her wrist.

As the blood dripped on the floor, she chanted: "Ani usiti potiu yem fata loya grimi creve bam cheve." Then, her blood solidified into a crystal as beautiful as a ruby.

"The Blood Oath of Fealty," muttered Edward as he knew he could control her life with this crystal.

"So, what do you want my help with?"

"I need help finding my little brother," said the Divine Maiden as she took a drawing from her sleeve. "He was swallowed by a Spiritual Disaster and is now lost in the Spiritual World. Over the years, I have divine he is still alive, but I could not find him."

Edward squinted his eyes when he saw this picture: it was Yami Sukehiro, the captain of the Black Bulls Squad, one of his friends.

"Are you sure this is your brother?"

"Of course. Do you know by any chance?"

"Get up," he said, helping her from the ground. The Divine Maiden could feel the sudden change in treatment, but she did not ask when he saw Edward deep in thought.

Yami told him he had come to the Western Continent on a boat. Although he hid his heritage as the prince of the fallen Hino Country, Edward never thought something was wrong with the story–except for how lucky the latter was to survive the arduous journey to the west through the terrible Grand Magic Zone.

Despite the anomaly, Edward thought it was because Yami was a man of Destiny, hence why he survived the journey even with his weak strength as a child. After all, he is one of the main characters in the storyline, and his fate is important.

Edward began to think about the implications behind this discovery. He never read Yami's mind since he never had a reason to, and he generally does not read the minds of people close to him.

So, he was a little confused about what was going on.

"Give me a drop of your blood," he said, and the Divine Maiden rapidly acquiesced. After taking it, Edward chanted something for a few seconds, and as expected, she was indeed related by blood to Yami.

"Did you find him?"

Edward did not answer as he connected to his clone in the Western Continent to contact Yami. Then, they discovered the latter's memories of coming here through a fishing boat were forged.

Instead, he was swept by a space storm that teleported him there.

Because the space storm looked similar to the Spirit Disaster breaches, the Divine Maiden thought he was in the Spirit Realm.

Furthermore, based on the clone's analysis, the person who did the forgery did an excellent job, almost undetectable by even him.

'God,' thought Edward. Yami's Darkness Magic is essential to open the Gate to the Underworld; this is why he was kidnapped in the main timeline of Black Clover (manga) by the Dark Triad, so he is essential to God's plan of eradicating the devils.

'Based on how God could manipulate everyone, it is very likely he can use some form of Fate Magic.'

Edward decided to be on the lookout for this possibility and prepare in advance. He then looked at the Divine Maiden, "Your brother is not in the Spirit World; he's in the Western Continent."

"Are you sure?"

"Yes. Although I'm not good at divination, I used a bloodline tracking spell to locate your brother's position."

"Thank you, thank you," she said, with tears and a sigh of relief. She worried something might happen to her brother in the Spirit World daily. Now, she was reassured he was alive and well on the Western Continent.

After processing her emotions, the Divine Maiden handed the blood crystal to Edward without hesitation. However, the latter declined; he did not want to enslave his friend's sister.

The Divine Maiden was surprised by this response, but she still said: "It does not matter if you don't accept; my loyalty still remained."

Edward nodded as he understood she could help him or Ozuki Akimitsu, to be precise, in his plans. "I will help you get to the Western Continent, but not now; before then, we have work to do."

Webnovel seemed to have done something to the fanfic novels on their website. So, if you want, you can go read on scribblehub or royal road: they are officially released there.
