It would be years before anyone in either society heard from either of them again. There had been a bit of a public outcry when Harry's emancipation and withdrawal from Hogwarts was announced. Mainly Hogwarts was upset because Harry had done so very well on his Owls and his teachers were looking forward to teaching him the following two years. But the public was only concerned over the issue of whether or not he would try to claim his Wizengamot seats while he was so very young still. When months went by without him appearing to claim them, they relaxed and allowed them to forget the Last Potter was now a legal adult in their world and one of their peers.
Very few people actually missed them though. Almost everyone wondered where they'd gone and what they were doing so the Daily Prophet made good money offer stories where they claimed the pair had been spotted in one place or another. Severus' name surfaced from time to time attached to a new potion discovery or an article in a potions related publication. A few sightings of Harry also made the news though most people had their doubts as to whether or not it was actually him in the photos. But for the most part, no one cared where they were or what they were doing.
As for the Dark Lord and his servants, Harry's words to Severus had proven true. The Dark Lord had never surfaced after freeing his servants from Azkaban. Gradually Amelia Bones and her aurors rounded up those freed followers and each one underwent a fresh trial. Some were returned to Azkaban but others went through the veil. One of them was Bellatrix LeStrange as she was caught red handed torturing a child for information on Harry Potter's whereabouts. A child who had no idea who Harry Potter even was. Let alone where he was.
And as for Albus, a few people questioned his disappearance but again not for very long. A tell-all book was released during what would have been Harry's sixth year exposing all Albus' secrets. Of which they were many. Including the fact that he hadn't defeated his former lover, Gellert Grindewald, in a fair fight as he claimed. Nor had he discovered on his own the twelve uses of Dragon's blood. Nor had he actually killed Grindewald as so many people believed he had. Just as he hadn't actually been trying to kill Tom Riddle the Dark Lord known as Voldemort. The book didn't come right out and call Albus a Dark Lord. Rather it let his true achievements and actions do that for themselves.
The uses of dragon's blood was actually nothing more but a compilation of discoveries made by others covering an entire century. These original discovers of the uses of dragon's blood were men and women who worked on dragon preserves around the world or worked with the blood to make armor, weapons and potions. Each had written a paper on what they'd discovered dragon's blood could be used for. And all Albus had done was compile those papers into a single document.
Gellert had been imprisoned in the prison he himself had commissioned under heavy wards that denied him visitors and the right to ever leave so long as a single breath of oxygen remained in his lungs or a drop of magic still lingered in his magical core. He had a house-elf that brought him food, fresh clothing, newspapers, books, parchment, ink and quills. But that was it. He wasn't allowed any visitors outside of Albus who came every once in awhile just to torment the man. Just because he could.
The story of his sister and the destruction of his immediate family was earth shattering for those who believed in him but vindicating for his brother, Aberforth. As it was compiled, like everything else in the book, from Albus' own journal where he had admitted he was the one to torture the five year old girl before confunding the muggle boys into taking the blame for hurting her. He'd done it according to his journal because he was angry with her over having to watch her for the afternoon while his Mum was putting up the vegetables from their garden for the winter and she'd been bugging him. His journal had gloated over how easy it was to torture his baby sister and blame the muggles for it. How gullible everyone was to believe mere muggles could hurt her so badly as to destabilize her core like that. And the author of the tell-all book made sure to include the actual journal passages in Albus' own very recognizable handwriting.
His journal also exposed his involvement with Tom Riddle and who Tom had grown up to become. Very little doubt was left in the readers mind about why Tom had become the Dark Lord he did. And it made it clear Tom was one of the lucky orphans who had entered Hogwarts Halls while the Castle was under the dominion of Albus Dumbledore. Many other orphans had entered that school only to leave it broken and destitute because Albus had discovered who they were and stolen the inheritance they should have been able to claim as adults long before they could do so. And most of those orphans never got the chance to tell anyone what the kindly old man had done to them. They disappeared just as quietly as they had appeared in the British magical society and no one had ever even thought to question their disappearance.
But through that exposition, his changes to Hogwarts as well as the reasons behind those changes were also brought out of the shadows. And of course his dealings with their hero, Harry James Potter came to light as well. All the people he'd either killed or caused to be killed were listed with the date and manner of their demise as well as the reason why Albus felt they deserved to die. Including all those orphans he'd defrauded of their rightful inheritances.
Needless to say, by the time the book was finished, no one who read it really wanted to know where Albus Dumbledore was. Those people now understood Albus Dumbledore had never had the best interest of their world at heart. The only interest he'd ever held close to his heart was his own. None of them ever questioned what became of him.
