Student and huge Harry Potter fan who's gutted it's all going to be over with Deathly Hallows Part 2. So, until J. K. Rowling decides to write some sequels, thought I might have a go...
To keep things 'simple' in my stories, I have set pieces of my canon that run through several, if not all, of my stories. Here are some of the most important:
Albus Potter and the Midnight Thief and A Rose By Any Other Name use the same OC characters and are part of the same universe, only set several years apart from each other, although the themes are very different.
Teenage Kicks Also uses the same OCs as my two other Next Generation fics, mentioned above. However, the storyline is not compatible with A Rose By Any Other Name, though many of my canon facts remain the same.
My Dramione fics Jar of Hearts and The Hardest Thing are compatible, but Resisting the Fall and The Runaway, my other Dramione fics are not compatible, and the latter disregards the epilogue entirely while the other three remain as canon compliant as possible.
Some facts, I keep the same throughout all my fics. Such as, in all of my fics featuring Draco Malfoy, he has since left the Manor and lives in Tarasque Hall and also has a House-Elf called 'Gil'. This does not mean that all of my fics featuring Draco are set in the same universe.
A minor one, but one that I mention in both my fics Someone Like You and The Runaway, is that in my head-canon, Neville and Luna spent some time as a couple after the war for a period of 18 months-2 years.
I think that's it...I hope that's vaguely coherent and helps those who were wondering about the various universes of my fics!
