It has been nineteen long years since HE-WHO-MUST-NOT-BE-NAMED and the Death Eaters were driven from the Wizarding World. The Trio (Harry, Ron, and Hermoine) were praised as heroes; while the fallen were immortalized. The Wizarding World eventually grew out of the clenches of fear, and oppression; following the new winds of freedom, and peace.
The stories behind the Dark Lords rise and fall were hidden, kept away from all wizards and those who knew were forced into Unbreakable Vows to keep it that way. Bands of aurors searched across the world, desperately looking for groups of rogue Death Eaters. In the beginning, stories of a third coming broke the silence; however, it was undeniable that the Dark Lord had finally perished from the living.
The Ministry of Magic engaged in a rapid reorganization under Kingsley Shacklebolt, and the Auror Department was given to Harry Potter. Azkaban was repaired and reinstated with newer Dementors, and more Wizard guards. Nineteen years passed and Hogwarts was still closed, though petitions raged; the school was simply inhabitable. No one wished to teach in graveyard of so many innocent lives, or in a place that the Dark Lord had cherished so dear.
Students were self taught, some were sent to Beauxbatons, and others to Durmstrang. A select few even crossed the pont to America, desperately awaiting magical education.
Numerous magical decrees arose over the nineteen years including that casting the 'Dark Mark' or anything in which resembles it, would lead to the Dementor's kiss. Underage magic became increasingly stricter, and life in the Wizard World was finally kept under wraps under the new Statue of Secrecy.
Finally, Shacklebolt had agreed to reopen the school under an old friend, and someone who he trusted. He gave me the position of Headmaster for the time being, in the midst of searching for a truly capable wizard.
Thank you for paying attention,
