Snowflake Challenge Day 12

In your own space, rec at least three fanworks that you think would make a good intro into XYZ fandom. Rec a fandom overview, a introductory picspam, stories that define and shape the fandom.

I'm not going to do this one exactly as it says in the challenge. What I'm going to do is rec the fics that I remember from when I first got into the fandom, the ones that stand out in my mind as shaping my introduction to it, selling me on my early favorite pairings or just sticking in my mind for whatever reason. And I've been around for like four years so these are going to be older fics, from 2008-2009 or earlier.

( I might keep adding to this as I remember things )
