(Sunrise's P.O.V.)
Swiftfang sure has changed the world very well, and to boot, she's very filthy rich after conquesting most of the Death Eaters' vaults. Last I heard had blown my mind! Her personal vaults from infatuation and use, has grown over 80 million, and with adding the other vaults, it had risen up to 637 million and very many valuables to sell as well. She sold the pensives, the potions to Severus's shop, the most of the jewelry, and clothes. She kept the books, trunks, and the head/heir rings and necklaces. From that point, it had risen up again to 700 million. Swiftfang has vowed to improve the orphanages, St. Mungo's and other places. She had converted the conquested manors and mansions into businesses, hotels, schools, and clubs.
Harry was sorted into Hufflepuff, Hermione into Ravenclaw, Neville into Gryffindor, Draco into Ravenclaw, Daphne into Slytherin, Ron into Gryffindor, Seamus into Hufflepuff, Susan into Slytherin, Blaise into Ravenclaw. The other usual years was sorted as normal.
Severus with Swiftfang's help was able to be a animagus, a brown Mamba. He was able to get into the Chamber of Secrets, and found the basilisk, called Kiji by her old master, Salazar. Severus told of the huge Arachnids in the Forbidden Forest, and Kiji was delighted to eat and get rid of the spiders. Once she was done, Severus and all of Hogwarts professors called India, and many park keepers came over, took over the transportation of Kiji to India to a huge island sanctuary where there was plenty of big prey for Kiji to enjoy.
The Chamber was kept as a room of discoveries, and converted into a huge dueling chamber for the dueling clubs.
Swiftfang was delighted to see the Ministry wholly changed, and able to allow many mundane things to be used at all the wizarding places like board games, plays, and much more.
Werewolves who took the 'Morph Effect' potion became wolf animagus with a timeline of 6 months to 2 years, depending on the person's body and dna. For other magical creatures, centaurs was able to live in other forests and islands, and mermaids, hippogriffs, house elves and much more was treated equally and fairly.
There has been talk of letting the wizarding world be seen by the mundane world, but for now, they're satisfied of catching up within the 20th century, and awaiting the 21st century around the corner. Swiftfang, keep changing the world and keep Harry and your family happy. I'm very happy to see that Swiftfang has found her true home, and she'll be all right although she is still searching for a cure for her daughter Lilani's cursed foot.
