Summary
Four digits. Reaching my 1000th fic is a big milestone, so I want to highlight what I like to write in the countdown to that big 1000th with a little retrospective before each story, while revisiting some of my favorite themes. Most of these could've counted as regular stories, but the timing makes them extra-special.
