Part II: Second Wizarding War (WWII)
1. The Boy Who Lived
Harry Potter, now orphaned, was taken from the remains of the Godric's Hollow cottage to 4 Privet Drive, the residence of his aunt Petunia and her husband Vernon, by Hogwarts groundskeeper Rubeus Hagrid. Minerva McGonagall, deputy headmistress, didn't want to leave Harry with Muggles, but Dumbledore insisted. Witches and wizards all over Britain knew his name, and declared toasts to the Boy-Who-Lived, who seemed to have conquered Voldemort. The headmaster decided it was better for Harry to grow up away from all that fame.
He left a note with the sleeping baby Harry explaining everything to the Dursleys; most importantly that they must allow Harry to grow up there and return there once a year in order to ensure his mother's protection continued working through her relatives.
The Dursleys let their nephew stay. But that didn't mean they liked it.
Because the Dursleys were Muggles, they had no understanding of magic, and even though Harry's aunt and uncle knew about his lineage, they wanted nothing to do with it. The Dursleys considered themselves a "normal" family and hated anything out of the ordinary. They lied to their nephew about his parents, claiming they had died in a car crash and that James was an unemployed drunk. They forbade Harry from asking questions about anything, especially about his parent's deaths. They discouraged any sort of imagination and screamed at or punished Harry whenever something unusual occurred, such as his hair growing back overnight. Harry didn't know it yet, but these strange events were actually outbursts of magic.
The Dursleys spoiled their son, Dudley, and made Harry wear his oversized hand-me-downs. They frequently abused and neglected Harry, including locking him in the cupboard beneath the stairs and overall bullying him.
Just as with any other young witch or wizard, Hogwarts sent Harry his acceptance letter on his eleventh birthday. After several failed deliveries, Rubeus Hagrid arrived to explain everything and personally take Harry to Diagon Alley for school supplies. During the trip, Hagrid enlightened Harry with the details of his past, including the true cause of his parent's deaths and the reason behind Harry's sudden popularity.
The Potters' vault at Gringotts contained more than enough money for everything Harry needed, from robes to books to wand.
Curiously enough, the wand Harry bought at Ollivanders had a twin, for the phoenix who gave the wand its core also gave another. Who owned the twin wand, do you ask? Lord Voldemort.
Unsettling coincidences aside, Harry very much enjoyed the day and looked forward to his new life in the magical world.
On September 1st, 1991, Harry Potter arrived at King's Cross station. There, he met the Weasley family, who explained to a very clueless Harry how to cross the barrier onto Platform 9¾. Aboard the Hogwarts Express, he shared a compartment with Ron Weasley. The two became friends immediately. Draco Malfoy's invitation of friendship to Harry, however, was refused.
The Sorting Hat placed Harry in Gryffindor at the start-of-term feast, and so began his first year at Hogwarts.
