Inside the house. Alexander, Arthur, and Ginni were seated at the dining table. He didn't have any place to stay or money to rent a room and it was already night. So, he was invited by the Weasley couple to stay with them.
Alexander didn't see any problem with that and they also had empty rooms as Bill and Charlie had moved out. He had told them that he would pay rent for the room later.
On the dining table, Arthur and Alexander were talking to each other while all the others were listening and setting up the table.
"Mr. Universe, how do you look so young even after being so old? I mean, if you had black hair right now, I'd assume that you are probably in your 40s." Arthur asked with much interest.
"Well, I traveled a lot and found many new magical plants and items. I look permanently younger due to certain failed yet lucky experiments. Failed because my hair didn't turn back to black" he made up the answer.
"Then, if one day you are able to perfect your experiment, be sure to share it with me mister Universe. I'd certainly wanna look younger" Molly Weasley chipped in while blushing and rubbing her cheeks.
"Absolutely, you'd be my first user, I promise," Alexander assured.
He really had an idea about making an anti-aging ointment.
~Those rich pure-blood bitc... I mean witches would go crazy over it, even if I sell it at a high cost~ he inwardly thought.
After dinner, he went to the second floor where the room was. It was Bill's room. Now it only had a bed, a table, and a wardrobe. He used scourgify to clean the room to perfection.
After that, he changed his clothes to a night suit and went to sleep. It had been a long day for him.
...
The next day he woke up early, cleaned himself, and dressed up in his usual clothes. Today, he was going to visit the Gringotts. He thought that if he has such a legendary past then he must have a bank account with some money too.
He went down to the dining hall and found everyone already at the table.
"Oh, sorry if I delayed your breakfast." he apologized.
"No. no... we just sat down a minute ago," Molly said and put a plate for him.
"So, what's your plan for today, Mr. Universe?" Arthur asked while eating his food.
"I'll visit Gringotts and some other shops in Diagon Alley today. But I need a guide as it's been a very long time since I've been there," Alexander stated and took a bite from his plate.
"That's easy. Take Ron with you, because he just lazes around in the house every day doing nothing and dreaming about going to Hogwarts." Molly suggested with a slightly irritated tone.
"That would be amazing, Molly." he cheerfully agreed.
...
An hour and a half later, they arrived in Diagon Ally via floo network. The street didn't look as crowded as it was shown in the movies most of the time. Probably because the Hogwarts year had already started.
His first stop was Gringotts. Ron was happily leading the way.
Alexander walked slowly while looking around and he had only one thought at that time.
Handuk happily took the money and answered.
"It's you and you are most certainly the richest wizard in British wizarding, if not the world," he stated.
Surprised by the answer, he asked for who the second and third were. Handuk showed unwillingness to answer and Alexander once again threw some money to him.
"The 3rd is Lucius Malfoy with 321,285,145 Galleons ($1.6 billion) and 2nd is Bellatrix Lestrange 421,686,753 Galleons ($2.1 billion). Now, no more questions." Handuk irritatedly said.
Now Alexander understood why the head Goblin's face fell at the authenticity of his identity. If he had never come back to claim the money then it would have belonged to Gringotts.
Alexander decided to take everything away. He sucked all the money into his dimensional space. He noticed a big chest was also being sucked and decided to open it later on.
Meanwhile, Ron and Handuk had their Jaws dropped to the floor. Ron had that expression because of the crazy amount of money and Handuk because of the crazy amount of money just vanished.
Alexander still left a thousand Gallons in it because he didn't want to close the vault permanently. He reckoned that he might still use it someday.
...
Then they returned back to the Diagon Alley and continued on their way. He thought that Ron might feel bored so he gave him 2 galleons and told him to go and eat something.
He then headed to Flourish and Blotts to buy some books about anything he could find. He knew that he wouldn't find any old books but still, he went there.
There he bought all the interesting books and books on Law. From there he headed to the Obscurus books. There he bought Fantastic beasts and where to find them, plus some other books on animals.
He couldn't find any significant book on alchemy or runes and no book about dark arts. So, he went to Knockturn Alley.
There he bought some books on dark arts and runes and also a book that piqued his interest. It was never mentioned in the movies. The book was called Eternal Darkness. He still could not find good books on alchemy.
He deduced that most of the good books must be strictly regulated and the best way to read them would be to either go to Hogwarts or infiltrate some ancient family's houses.
He returned back and headed to the Ollivanders.
The shop was open and Garrick Ollivander was cleaning some wands.
"Welcome, Mr.?"
"Universe, Alexander Maxim Universe"
Garrick Ollivander's eyes shone at the mention of his name.
"haha... so, the legend returns. What can I do for you today, Mr. Universe?" Garrick politely asked.
"I am looking for a wand. I've never really felt a need to use a wand, but I want to try it, once" Alexander answered.
"Yes, yes... Wands can help wizards and witches to create a more powerful spell... but again, the wand chooses its wielder so I can not say anything until we try," Garrick said and went to the side to bring some wands
