And, if you are inclined to think of the "New Place", the place where Cecilia and Septimus were pushed through the veil in the Department of Mysteries along with Lindvald Halen, Albus Dumbledore and Gellert Grindelwald then the only snippets of information that I can give you are these.
After the destruction of the Department of Mysteries and the Veil, through which now nothing could ever pass, the citizens of the "New Place" seemed to stop, on that very morning and take stock of what the hell they were doing. A lot of head-rubbing had gone on and thoughts along the lines of how in Merlin's name they could all have let it all happen.
Or of Sam Potter's new life in Iceland, and election as the country's first wizard at the Althingi, the Icelandic parliament. Of Harry and Hermione's delayed wedding, and attendance by both Lily and James, who had grown happier once they had divorced and were leading separate lives. Of the three young boys who continued happily at Hedgewards, the least magical of them, Julian, gaining the highest marks of their year and becoming a geologist specialising in rocks with healing properties..
Of to experimental communication and its application into telecommunications and the Floo network. Of Darren, the least academic of the lot promoting quibball and becoming a sports reporter. Of Snape, who reassumed the position of Headmaster, and presided over the funeral of one of the greatest statesmen the country had ever known.
Of the attendance to a funeral by his brother. For, the instructions had been found as Harry and Hermione went their separate ways. Of Hermione's recommencement of work at the newly-reformed Strasbourg and Harry's promotion to the cabinet as Auror to the Hovel Office.
From his desk, opposite that of Caelius Lupin, Harry read the words again, on parchment that he knew had been blank the day before.
"A solar eclipse will take place in six months from now," were the words written, and he remembered Hermione reading them aloud on their last day in the house together. "As the silver replaces the iron in the blood cells temporarily, the solar eclipse will give a strong enough irradiation of the body of sunlight to eradicate the vampirism vector, shortly after totality. It's his only chance. You must take him out in direct sunlight. It will work, Severus. Remus, my beautiful Remus will be free of vampirism permanenly."
Lindvald Halen watched as Harry read Cecilia's words and then turned his back on that world forever.
