"Grab my arm," said Grindelwald to Daniel Davis outside the protective shield of Nurmengard Castle after Dumbledore had left.
"Apparition?" Daniel immediately grabbed Grindelwald's left arm.
Who knows what Grindelwald and Dumbledore had discussed, but when they reappeared before Daniel, Grindelwald had a wand in his hand. With a wand, this prison could no longer hold him.
In the world of Harry Potter, having a wand versus not having one makes an immense difference—far greater than the difference between an ordinary person with or without a gun.
Upon grabbing Grindelwald's arm, Daniel felt as if he was spinning through space. When he reappeared, he was on a very old-looking street. The people on the street were mostly dressed in black robes, and a sign told him this place was Diagon Alley.
Outside Nurmengard Castle, shortly after Daniel and Grindelwald had left, a golden portal silently opened. A figure in yellow robes stepped out, revealing a bald head when the hood was lifted. It was the Ancient One, who had also arrived in this world.
Daniel would never have imagined such a thing.
Gringotts, the wizarding bank.
After bringing Daniel to Diagon Alley, Grindelwald headed straight to Gringotts. Upon presenting his credentials, the goblin staff became very respectful.
"Vault 444." After navigating the complex underground tunnels, Grindelwald and Daniel arrived at this vault. Grindelwald took a large amount of gold coins from it—gold Galleons.
"A Non-Traceable Extension Charm, huh?" Daniel guessed the situation immediately upon seeing a small bag hold so many coins.
This charm was something Daniel was very eager to learn. The most impressive example he remembered was Newt Scamander's suitcase—it was simply amazing.
"Is there anything you want to buy?" Grindelwald asked with a smile after they left Gringotts.
"A wand," Daniel replied after some thought.
In the world of Harry Potter, wizards are entirely dependent on their innate talent. You are either born a wizard or not; there's no way for ordinary people to become wizards.
Judging by Dumbledore and Grindelwald's attitudes, Daniel was certainly a wizard, not a Muggle.
Whether he was born that way or it was because he practiced the magic of Kamar-Taj, Daniel wasn't sure. He tended to believe it was due to his Kamar-Taj training.
Although Kamar-Taj sorcerers engage in physical combat with weapons, the principles of Kamar-Taj magic are incredibly high-level, almost divine, which is something the Harry Potter world, with its innate talent dependency, can't compare to.
Ollivanders, a historic wand shop, supplies most of the wands used in England.
Daniel was curious why people in this world didn't buy spare wands.
"He needs a wand," Grindelwald said directly upon entering the shop.
Hearing Grindelwald, Ollivander carefully examined Daniel before selecting a wand from the many boxes and handing it to him.
"This is ebony wood with a core of dragon heartstring from the Orient. Try it out."
Bang.
As soon as Daniel grasped the wand and gave it a wave, an invisible shockwave burst from its tip.
Magic doesn't always require incantations. Attacks like the one Daniel just performed are common in wizard duels, where there is no time for chanting spells. Using such attacks to buy time for spellcasting is a common tactic.
In other words, this kind of attack can be considered a magic power impact, which, being pure magic, usually has weaker power.
Next, they visited Flourish and Blotts. Daniel purchased all seven years' worth of Hogwarts textbooks and several books on wizarding history and notable figures.
Though his requests were unusual, the store still sold them to him, likely because of Grindelwald.
The two then Apparated directly to King's Cross Station.
Though curious about Diagon Alley, Daniel figured he could explore it later. For now, he needed to show Grindelwald some results from his plan.
Dumbledore and Grindelwald weren't fools; they were among the smartest people in this world. Though Daniel's story had many holes, the plan's potential made them overlook these flaws.
Just as Grindelwald said nothing when Daniel bought a wand and all the magic books.
These items were quite expensive—his wand cost six Galleons, one less than Harry Potter's.
This amount seemed small but was actually quite costly. Most people in this world only have one wand for life, probably due to the expense.
Look at Ron, who had to tie his broken wand back together, causing spells to backfire.
Not to mention the cost of those magic books, which were several times more expensive than the wand.
After leaving King's Cross Station, Daniel led Grindelwald around. Wizards generally knew little about the Muggle world, especially Grindelwald, who had been imprisoned for decades. Even with occasional updates from Dumbledore, they were focused on the wizarding world.
"First, we need to exchange money." Daniel had brought a lot of gold bars, which can be considered a universal currency across multiverses. The reason gold is used, probably, is due to its unique properties.
Gold isn't just currency; it's also a raw material.
Thanks to the teachings of Ada, Daniel knew how to handle the money exchange smoothly.
"The technology level of this world is too low," Daniel remarked after buying a house in London and investigating the world's technology. He was disappointed, even though he had tried to keep his expectations low.
"Magic has suppressed technological development," he realized.
"Looks like I wasn't lying to Coulson," Daniel laughed as he looked through the books on magical history.
Famous scientists like Newton and Einstein were all wizards, and even the development of the atomic bomb had a major wizarding influence.
After learning the basics of magic, Daniel understood why this was. Though this world's wizards rely heavily on innate talent, they still follow a principle: the smarter you are, the more likely you are to become a wizard.
Talking with Grindelwald about his and Dumbledore's past, Daniel suddenly thought of the striking similarities between Grindelwald and Dumbledore's relationship and the rivalry between Red Skull and Captain America.
In this world's WWII, Grindelwald was essentially the Red Skull.
