Fem Harry runs away from the Dursleys after Vernon tries to shot her with a gun. She gets to a place that was maybe called the inbetween and is saved by a woman who kind of adopts her. I think the woman is a vampire, but not sure.

There are two other mentor figures for her, some kind of dark mage they visite in another dimension and a kind of omnipotent person (I think she was female).

The woman who adopted her is hunter by the ICW and they attack their home and kill her. Her sole gets pulled in some kind of bottle and Harry want to find a way to get her back.

She finds Hermione, whos parents left her in a forest, in some kind of magic enclave where they work together.

Someone (maybe Snape or Lupin, idk) is searching for Harry but I dont think they meet as of now.

There are different world or dimensions in the fics that are explained and you travel there in this inbetween.

Would be really cool if someone knows the name :)

Its a bit hard to described what I mean with "world building", but basically what I am looking for is something where more than Voldemort happens in plot...

The in my opinion best example would be "The Good War", where you have lots of additional stuff going on (its also still updating regularly :). Maybe also in Rigel Black.

The only thing I find important is that its really really long and preferably finished or updating regularly, going over multiple school years.

Romance can be included, but should not be the main plot please. The examples I gave are fem!Harry, but thats just a coincidence, not a requirement.

Edit: Basically all fics that are not totally copied from the books (plot wise) and include many school years are welcome. Because even that is something I struggle to find
