The greatest, in many rabidly obsessed people's opinions, "Marauders' Era" (circa 1970 Hogwarts)
Harry Potter fanfiction EVER. Written by Lady Jaida and Dorkorific and hosted on LiveJournal, it has become widely popular and there are heaps of readers who
believe that it is canon—J.K. Rowling who? It is meant to be Remus/Sirius slash but remains nearly gen for at least the first nineteen parts.
"MERLIN'S BEARD," I shrieked into my
unfortunate friend's ear, "SHOEBOX HAS BEEN UPDATED!"
She sniffed
disdainfully and made an off-handed comment about how Remus/Sirius slash is wrong and her
personal OC, an author avatar by the name of Mary-Sue—I mean, Crimson Midnight Slytherin, fits much better with both Remus and Sirius. And James, and Lucius, but not Tom Riddle because they're related and that would be "icky."
I smacked her with a pillow, initiating a catfight much like those between Narcissa Black and Carmina Rosier.
