The morning was quiet at Leaky Cauldron when suddenly someone knocked at Wilhelm's door, the knock was sudden tho not unexpected.
Wilhelm who was already awake walked up to the door and opened it. He was greeted with the sight of Tom who said "Someone from Hogwarts is waiting for you downstairs." Wilhelm nodded and replied "Thank you for informing me, I'll be there in a moment."
Tom walked away as Wilhelm walked inside to grab his wand. Tucking it in his wand holster, Wilhelm prepared to meet whoever has arrived from Hogwarts.
Walking downstairs Wilhelm saw a women in an emerald green robe, sharp eyes behind square glasses. Wilhelm knew who she was, The Deputy Headmistress and transfiguration professor at Hogwarts, Minerva McGonagall.
"Mr. Grehman, I presume?" said McGonagall.
Wilhelm gave her a polite nod as he replied, " Yes, that's me."
"I'm Professor McGonagall, Deputy Headmistress at Hogwarts. I came to accompany you to get your school supplies."
"I've already bought everything Professor McGonagall. Books, cauldrons, trunks, robes. The only thing I recently got was the wand after receiving the letter of acceptance."
McGonagall blinked in surprise," Is that so? I see. That's unusual, most students wait for their letter to arrive before they buy supplies."
Wilhelm shrugged his shoulders and replied,"I like being prepared."
"You seem very capable for your age," McGonagall said as she sat down at a nearby table and gestured Wilhelm to take a seat across her.
"I couldn't help bun wonder, are your parents magical Mr. Grehman?"
Wilhelm nodded his head as he looked down at his hands and said,"Yes, my mother was an echantress and my father was an alchemist." Take a deep breath he continued,"They both died 7 years ago due to a magical mishap."
"I am sorry to hear that....A magical mishap you say?" McGonagall asked although she guess that it probably involved some accidental magic which is why Wilhelm kept looking at his hands thinking he'd been the one to kill them.
McGonagall was right, Wilhelm did thought he killed his parents but it didn't involve accidental magic.
Wilhelm nodded his head at McGonagall's question. She studied him for a moment trying to figure out what happened from his expression, there was a silence between them.
"You have been living on your own since then?"
"I manage," Wilhelm replied."I learned to take care of myself."
"I must admit, that's not something many eleven-years old can say."
McGonagall stood up from her seat as she said,"Regardless, you'll be attending Hogwarts School of Witchcraft and Wizardry and I am sure you will find it a good place to continue your education. If you ever need anything support, guidance or even help you can come to me."
"Thank you, Professor."
"Well, I suppose there is no need for me to take you to the Diagon Alley since you have already bought your supplies. Here's your ticket, we'll send an escort to guide you to the platform on September 1st."
"Understood."
"Take care until then, Mr. Grehman." said McGonagall before leaving.

As the days went by Wilhelm focused on recreating several devices from the future, like brewing stands, burners, cold storage devices, devices that could analyse rune circuits and calculate the probability of them being successful or a failure.
Wilhelm's laboratory was slowly turning like the one he had at The Arc–A total mess. The once clean room was now filled with broken equipment, half-finished devices, rune circuits and wires.
"Alright it's approximately 11:00 in the morning, today is 23 August 1991, I have made progress, on the rune analyser and recreated the analysis rune circuits."
"Both the Bio and the Mana computers are a work in progress the Bio computer will be easier to create as it was created after 2070, the Mana computer might take some time as the current technology is unable to interact with it."
"Mana analyser is also a work in progress but without the Bio computer it will be of no use."
"Hardest part currently is making 'Mana Compatible devices' because althought I know how to make them the current technology is ancient."
"I'll be storing this memory with the memories of Project : Paradox so in the future if they have the technology to digitally view it the better or they can simply use a pensieve."
"Reading through the history books has revealed that I might find some goblin technology from the late 1800's as they had several bases near Hogwarts and it's surrounding villages."
"Although I am not sure if I can find anything useful there but goblin runes circuits or even ancient ruins might help me because I am sure one of these ancient rune arrays was the one sturdy enough to withstand the Mana Engine's heat."
"In 8 days I'll be going to Hogwarts, there I'll be able to closely study these ruins and hopefully find more ancient runes."
Wilhelm places a wand in his head as he extracted his memory and stored it in a glass vial. He was doing this as a precaution, because if in the future he somehow died someone would be able to use his memories to find a solution.
Wilhelm places the vials in a suitcase where several memories were labelled and stored. All of this was overwhelming and exhausting for Wilhelm he didn't quite think he'd have to start from nothing if only his equipment had survived he'd have taken things easier but alas there's nothing he could do except wait for September 1st to arrive.

A few days later on September Wilhelm was having breakfast downstairs as he saw a girl enter the inn, the girl had bright pink hair and was wearing a leather jacket and jeans. She looked around the inn apparently looking for someone as her eyes landed on Wilhelm she walked over and asked.
"Wilhelm Grehman?"
Wilhem nodded and replied,"That's me. Do you need something?"
Wilhelm slightly recognised her if he was not mistaken she was Nymphadora Tonks–Future auror and a metamorphmagus.
Tonks smiled as she replied," Professor McGonagall sent me, I'll be your student guide and escort to Hogwarts express."
