Epilogue:
In the end, Sirius stayed on for the next three years teaching History of Magic, in order to stay close to his godson and his betrothed. His decision might have been influenced by the appointment of Hestia Jones to the DADA post. Within the first several monhs of 5th year, Harry and Hermione noted that Sirius could often be found within close proximity of the attractive Auror. They eventually had several children.
They finished their OWLs with some of the highest scores that had been obtained in the last several decades. Harry had tired to give up Divination but as he had missed two years of every other subject, he was forced to attend through the end of 5th year.
Although there was no longer a threat from Voldemort, Harry instituted Hogwarts Army as a group trained in the defense of Hogwarts and the wizarding world. Many members ended up as Aurors.
Harry was finally fully seduced by Hermione on his 16th birthday. Up until that time, they had enjoyed various activities, but Harry had held out till the "age of consent". Hermione had been very flustered many times during 5th year. During 6th year, she was often seen to be smugly satisfied while Harry always seemed to have a goofy grin.
They were married on Harry's 17th birthday just in time for them to move in together in the Head Students' dorm.
Snape eventually produced a cure for Lycanthropy by the use of some revisions to the Wolfsbane potion to include a muggle antiviral agent, delivered by Hufflepuffs Cup. Within 3 years, the werewolf problem was recognized as a disease and different Ministries of Magic throughout the world ponied up the costs to send their werewolfs to England to get cured.
Harry was ecstatic when Remus and Tonks provided him with his godson again, although he had to fight Sirius for the privilege.
Both attended Oxford University. Their first success was getting the relations with goblins moved from the Department of Magical Creatures to the Diplomatic Office.
Several house elves had bonded with them. Hermione pushed through laws allowing house elves to rebond with the wizard or witch of their choice if they were found to be abused. Several pureblooded families had to hire help to feed themselves.
Winky and Dobby had several children. When Harry was 140, both passed away. Harry and Hermione grieved for a time for their lost friends.
Neville and Luna had become an item, but it did not last and they ended amicably. Luna later married a wizard named Rolf Scamandar, who was a fellow magical Zoologist. They discovered many rare creatures together. Luna and Hermione remained very close throughout their lives.
Neville married Hannah Abbot and became the Herbology professor.
Ginny married Colin Creevey. Hogwarts Army had settled Colin down, and the two used their money to invest together in various interests which caused them to end up very wealthy. Ginny had played quidditch and wrote for the daily prophet. Colin worked with her as a photographer.
Dumbledore slowly faded into dementia. He was relieved as Headmaster just one year afer the defeat of Voldemort. He died a lonely and broken man.
Molly eventually gave up her plans, but not before alienating every member of the family except Ron. She and Arthur separated and she moved back in with her Prewett relations.
Ron eventually ended up with Lavender Brown. He was a henpecked husband who worked as the equipment manager for the Chudley Cannons. Somehow his teenage years hadn't prepared him to handle athletic supports and such.
Larry and Bob continued to visit, although the visits were rarer and rarer as the years got on.
Both Harry and Hermione ended up at Hogwarts after spending several years as political reformers. The pureblood philosophy had died and the wizarding world ... no, the magical world ... was a much more equitable place to live for all wizards, witches and other magical creatures.
Harry had taken on the post of Deputy Headmaster while he saddled Hermione with Headmistress. He was perfectly willing for Hermione to be the face of Hogwarts as she was already well known for so many laws and practices that were now common throughout the world.
When the two passed away at age 179, just as Larry had originally told Harry all those years ago, their funerals were attended by 100,000 witches, wizards, goblins, house elves and other magical creatures. A quidditch stadium had to be used. Ragnok, the aged Chief of the Goblin Nation, delivered the eulogy as one of Harry's oldest and dearest friends. The funeral procession to their final resting spot was miles long and presented numerous challenges to the Ministry of Magic.
Harry and Hermione found themselves in an office in front of a desk. When they looked at each other, they both saw they looked just as they did at age 21. Harry, with his younger body, started reacting to Hermione. Hermione had her own reactions. Until ...
"Hiya guys!"
Both groaned and looked over the see Larry coming in the door.
"Hello, Larry."
"Welcome to Afterlife Inc. I am your Grim Reaper Larry ... oh what the hell, both of you know where you are and who I am. So, finally, are you happy to have made it through to your destinies?"
Harry and Hermione looked at each other and shrugged. "Sure," Hermione answered, "what's next?"
"Well, Bob and the gang down at Destiny Repair and Lora and I and a few other Reapers are going to get together and have a party. You're both invited!"
Harry and Hermione were dragged by Larry down to the recreation room. Lora was introduced by Harry to Hermione. "Your soulmate was considerably more trouble without you in the picture. I am very happy to make your acquaintance." Harry blushed as Hermione laughed.
Bob dragged them over to the Destiny Repair group for a shot. Hermione remembered something. "Who was the Destiny Repair person who suggested Harry have a Harem?"
Several people grabbed one person and pushed him up to the front. "This is Sam." Hermione greeted Sam, shook his hand, and then smacked him upside his head. "That was for the Harem suggestion." Sam smiled sheepishly as everyone laughed.
After several hours of partying, a very inebriated Larry led a tipsy Harry and Hermione up an elevator.
Larry took them to a door. "Theesh is whar de board meetsh." Larry opened the door and led them inside. The room was empty, except Harry noticed there was a figure near one of the windows. Larry, when this was pointed out, started to fall down in his nervousness to get out.
"Ahhh, Lawrence. It was so good of you to bring your clients to meet me, I was so looking forward to it." The elderly gentleman came into the light. "My name is Myrrdin, otherwise known as Merlin. I had hoped to meet you two. I must say, that the final decision to send you back, Mr. Potter, produced results no on had expected. You and your soulmate moved the destiny of the magical world forward by nearly 1000 years. It was very fulfilling to watch."
Harry and Hermione were a bit awestruck. They thanked Merlin for his kind words. "Well, suffice it to say, in the future you may be called upon to serve on the Board of Afterlife Inc. It is a 1000 year commitment, but the job can be satisfying. I have served 812 years as of this moment." Hermione looked more interested than Harry. "Well, I will let your reaper move you to your final reward. Oh, and Lawrence?" Larry looked to Merlin bleary eyed. "Should you find yourself coming to the Boardroom inebriated again, I should remind you there are openings still for Bargemasters on the River Styx." Larry thanked him and escaped, missing the wink Merlin gave to Harry and Hermione.
