Harry Potter Universe

Travelling across the stream of light, John had crashed right into the middle of an open field near the Forest of Dean.

Opening his eyes, John took in his surroundings before using the reality stone to create a small house in the forest. The reality stone created stone and log from the air as it formed together to make a cozy cottage.

"Perfect." John mumbled before realizing where he was.

'I'm in the Harry Potter universe in 1991 the year the boy who goes to Hogwarts.' John thought.

"Wait isn't he like eleven or something. We can't have that now can we." John snickered to himself as he once again used the reality stone to change three things.

Firstly, any and all first year students at Hogwarts where now eighteen years old and the other years are just an extra year older than the previous year.

Secondly, basically the timeline has accelerated by seven years meaning it's technically 1998 but it's the year 1991.

Thirdly, John is now to receive an invitation to Hogwarts School of Witchcraft and Wizardry.

"There we go all better." John snickered to himself.

Within a total of five days, John received his Hogwarts letter and has set off the Diagon Alley to buy the necessities for the school year.

During his trip to Diagon Alley where he had to create a Gringotts account which he filled with over a million galleons thanks to the reality stone, John had a very uneventful day meeting absolutely no one.

When John arrived back home, he immediately started to practice using magic which was a very downgraded version of the reality stones. Although he got the hang of magic quite quickly, he was a prodigy after; it was with the infinity stones mainly the time stone and reality stone that achieved these results.

The time slowly came for John to travel to King's Cross Station he used the power of the infinity stones to shrink his luggage and teleport him into the bathrooms where he proceeded to walk towards Platfrom Nine and Three Quarters and go through the barrier.

It took him less than five minutes to find a compartment and get on the train when he decided he needed a victim...test subject...volunteer, he meant volunteer to test the mind stone one.

And just like that, fate had brought John his first test subject.
