An aged up (from like tiny kids to young teens) AU where the kids, nighttime villains and heroes alike, confront a malevolant force that's been brewing in the scenery of their lives for years. It involved a lot of personal drama stuff and tied the book lore and show lore together.
I'm never coming back to this but I'll share the building blocks for the sake of younger me. Why not?
Things Change - The beginning to this AU, a three chapter story focused on each of the main three.
Beware the Mascoundrels! - A oneshot tying book character into the show, giving them backstories.
Lilifee's Encounter - Another oneshot tying a (former) book character into the show!
Qernz Haerfgvat, Yvrf Funerq. Jurer ner jr tbvat? Jub nz V? - Longfic meant to tie it all together, but I didn't have the discipline for this kind of thing back then and dropped it.
