Dolores Umbridge walked out of the courtroom, her job done. She dropped by the Educational Board, leaving them with a small amount of paperwork as the Educational Decrees would be lifted later that day. Minister Fudge was, right now, making the announcement that Albus Dumbledore had been admitted into the Long Term Care Ward of St. Mungo's, while Harry Potter was on his way to Azkaban.
She had made a few suggestions to the Minister, which would help in dealing with the supporters of the deranged boy wizard, and Lucius Malfoy had agreed to help fund them. She doubted there would be any problems with some supposed dead Dark Lord returning.
A few months later
"What do you mean 'The Queen wishes to speak with us'?" Minister Umbridge asked, having stepped into the role after Cornelius Fudge had a terrible accident during another attack by the muggleborns.
"I do not know, Minister..." Lucius asked, "I will go with some Inquisitorial Squad members and see what she needs..."
She nodded. The Inquisitorial Squad had been pivotal to the Ministry's handling of the continued unrest. She'd not even heard of anything involving the supposed Dark Lord's attack on wizarding culture, just a few skirmishes between her Squad and Aurors who felt her actions were heavy-handed and counter-productive.
That evening, she got a report from Lucius Malfoy that they'd been ambushed by some halfbloods and muggleborns who had set a trap by putting the Imperius on the Queen. Unfortunately, the Queen and her entire direct family had been caught up in the incidents.
"I have made sure that the 'Order Of The Phoenix', a maverick group who used to work with Dumbledore, have had their faces given to the muggles as the cause of the terrible deaths..." Lucius continued. Umbridge smiled.
As unrest continued, the Ministry held fast, Umbridge being hailed as the leader of a new golden age for wizarding kind, with the disillusion of the term 'half-blood' and 'muggleborn' after the muggles of England were forced to accept their superiority.
She never did meet with the leader of her Inquisitorial Squad, Tom Marvolo Riddle, who had been the spearhead for her absolute control of the Wizarding and Muggle worlds...
Otherwise, she might have figured out why Lord Voldemort never returned.
