Hogwarts Muggle Rise
Travel back in time to the chaotic world of Harry Potter... Probably. Burdened with the Prime Minister's trust... No. Plotting to subvert the Ministry of Magic... Can't.
That's all you can do, make more friends and accumulate strength first.
"So I'm really not a bad person, I just want to be friends with you." Countless years later, Anthony said as he watched Voldemort rise again.
... Serious Introduction: Back in London, Burdened? In 91, the United Kingdom promulgated the "National Special Talent Protection Act", and in 92, MI5 and MI6 established a nationwide wizarding monitoring agency: WIC (WizardIntelligenceCommittee) Wizard Intelligence Committee, and spread to the entire Commonwealth.
The first Royal Wizard Auror unit in 93 was officially established. In 94, 95, and 96, the situation changed abruptly, wizards declined, and the great war was about to rise, and Muggles rose rapidly in one change after another.
This is a story about the protagonist who makes friends and tries to subvert the Ministry of Magic... PS: (Don't bring it into reality)
