Filed Under HP themed lists |
A fair warning: I’ve been out of HP fandom for quite a while by now. As I read HP fiction nearly not at all nowadays, please don’t expect these listings of mine to be kept up to date. If you report a broken link or suggest a new addition, I might fix/add it… in half a year. So please don’t use these lists as a proper gateway but rather as a general guidance for what to look in other places if you find a dead end here. For new stuff, check comments.
Alternate dimensions in Harry fics
What I take:
- dimensional travel or fics where parallel/alternate dimensions co-exist. I.e. our hero travels not to the past or future but to another dimension within the same time frame as their own (usually). For example, A Slytherin in Gryffindor Clothing (see below).
- they must be the alternate dimensions of the same HP reality! Only the same reality. No newly invented places.
- I can’t emphasise it enough: the character has to travel to another reality. If not travel, then we need to see both words in the fic.
- multiple dimension fics, like The Pendulum of Choice.
- stories where the hero wakes up in a mental hospital, thinking that his world is all in his head — often written after the Buffy the Vampire Slayer episode based on this concept. Such stories fit if the two realities are shown as equal and we do not know which one is real, like in Oscillate Wildly.
King Draco’s Code, or What I don’t take:
- no time travel. If the hero just travels to another time, it goes to the Time travel list.
- NB! no fics where the hero travels to a non-Harry reality, such as Discworld, Middle Earth, and so on.
- NO simple AU fics (i.e. the fics the entirety of which shows a different reality — see travel above).
- no WIPs that have only a chapter or two written; I’d also prefer no abandoned WIPs that don’t show most of the story.
- no drabbles;
- do not bring fics that you haven’t read;
- do not bring fics that you didn’t like;
- do not bring fics the authors of which show no decent grammar or spelling skill even if you liked them;
- PLEASE: I have little free time recently, so do me a courtesy, do not leave only a link. I’d be really grateful if you tell me (besides the title and author) whether the fic is a WIP or completed, what the pairings and the rating are; what kind of alternate dimension there is. You’ll spare me hours of rushed reading! If you are unsure about a certain fic, describe it in some detail and ask.
Fics are sorted in alphabetical order by TITLE (articles excluded).
These are NOT my recs; it’s just a themed listing.
# - liked
## - loved
NR - have not read
new - added in the last month or so.
NB: Have a look at the list of multiple alternate universes in one fic, compiled by xenobart
The A/N at the end of the chapter 4 of unzum’s fic Disappear lists lots of Alternate Dimension fics posted at FFnet. The info includes author and title. Those who are interested can go look for these fics using FFnet search engine. I haven’t checked them; I don’t have time for it. If you are a fan of the theme, please go browse on your own.
