Oh, this was wonderful! Fantastic job on meeting all the requests and on creating a charming and entertaining story.
This had to be my favorite line: “but the incantation is very similar to an ancient marriage bond. Easy mistake to make, actually. Sorry about that.” OMG! That is just so very typical of the Wizarding World and I can absolutely believe something like this would happen to Harry. I love the light-hearted tone of the story and Mulciber was an OC that'd I'd love to see make a reappearance. Not to mention I wouldn't mind being a Animagus on the wall when Harry and Severus find out about that procreation part. ;D Fantastic work, hon!
