By the time next morning rolled around Harry had come up with a tentative acronym name he'd liked. Spell Crafted Ocular Unit Total Energy Reader or S.C.O.U.T.E.R. for short. Saying the full name was a mouthful but calling his Magic Quantifier a Scouter made some sense. Any Magical Being within thirty meters of Harry could have their total amount of mana 'scouted' by him so he would at least know their relative magical strength compared to his own. Plus he'd broken down his prototype's main features to come up with the words used in the acronym. Spell Crafted for how it was made, Ocular Unit because it was used by the eye, and Total Energy Reader because it told him the total amount of mana, which is what he called magical energy, a Magical Being had at their full strength. There were definitely still adjustments and improvements that could be made to his Scouter but for his first totally original design Harry felt that he'd done well.
A loud knock on the front door alerted everyone in the Dursley's home that someone had arrived. Harry made his way down stairs from his room only to see Vernon at the door looking gob smacked at the large, hairy man standing on his doorstep. This was probably the staff member from Hogwarts and Harry was already too curious to hold himself back. With a quick movement he had his Scouter at his eye and was scanning the huge man for his mana amount. Harry's eyes tried to follow the rapidly growing number on the lens but lost track quickly. When the number came to a stop Harry almost stumbled back in shock. There on the lens was the number '7,062'. Harry almost burst with questions just from the number alone. Was this an average reading for Magicals? Was it higher or lower than normal? How had the large man gotten such a high amount of mana? Why was he so large? Was it because he had so much mana? Question after question appeared in Harry's mind before he settled on a single realization to try and calm himself down. His '270' mana wasn't very much when compared to this man's. He'd need to look into becoming a bit more magically powerful in the future; it never hurt to be prepared after all. Quickly putting his Scouter back at his waist he walked down the stairs catching the large man's attention.
"There's Harry, look just like yer father, yeh do." The large man laughed as Harry came to stand beside Vernon.
"You knew my father?" Harry asked curiously. Vernon and Petunia had only heard about his father a few times from his mother, so neither of them knew the man personally. This could be a good chance to learn something about his parents.
"I did indeed, bit o' a prankster in his school days. Grew up ter' be a respectable wizard though." The huge man grinned; at least Harry thought so with the way his eyes crinkled upwards.
"Are you here to take me to get my school things?" Harry asked getting a nod from the large man.
"Aye, I'm supposed te' take ye up te' Diagon Alley ter' buy yer school things." The man grinned happily. "Name's Rubeus Hagrid, Keeper of Keys and the Grounds of Hogwarts."
"Thank you for your time, Mr. Hagrid." Harry smiled back.
"I'll have him back in a few hours. Don't suppose he'll even be late fer' dinner." Hagrid nodded to Vernon getting a small nod back. With that Harry followed after Hagrid and the two made their way to the nearest bus stop. Throughout their trip towards London Harry asked Hagrid dozens of questions. Most of them were about his parents and the rest were about the hidden Magical World. Hagrid had been able to answer the majority of his questions so Harry had been mostly satisfied during the trip. When they stopped in front of a dingy pub called 'The Leaky Cauldron' Harry couldn't keep the unimpressed look off his face.
"This is the entrance to Diagon Alley?" Harry questioned Hagrid.
Hagrid chuckled at the confused tone in Harry's voice. He supposed that the Leaky Cauldron really did look a bit out of place when compared to the more modern surrounding buildings.
"Indeed it is, Harry." Hagrid nodded. "Remember what I told ye; yer quite famous in the Wizarding World. So we'll try ter' make our way through without drawing attention." Harry grimaced not sure a man of Hagrid's size could go anywhere without drawing attention. He was also a bit skeptical about this supposed fame of his, but would prefer not to cause a scene if possible. Quickly making sure his hair covered the faint scar on his forehead the two entered the Leaky Cauldron.
"Afternoon, Hagrid, the usual?" The man at the bar called as soon as Hagrid walked through the door.
"Not today, Tom, escortin' a new First Year through Diagon." Hagrid replied as he gently patted Harry's shoulder. The pat still almost sent Harry to the floor though. They were quickly able to pass through the Leaky Cauldron without incident and were soon in Diagon Alley proper. Harry had thought the brick wall that separated when certain bricks were touched was a cool trick. Diagon Alley itself featured a cobblestone road that was too narrow compared to a modern street and a variety of smallish buildings selling all sorts of strange things. It looked like something one might see in a history book about London by Harry's reckoning.
"Come along Harry, our firs' stop is Gringotts, the Wizarding bank." Hagrid whispered lowly, not wanting to give away the boy's identity.
"What are those?" Harry asked surprised as he saw a pair of obviously non-human guards while they were walking up the steps of the bank.
