Small Fandoms Fest
smallfandomfest is currently taking prompts for fanfic and fanart in small fandoms - Eroica qualifies, since it has less than 2000 fics online. I made a fandom primer for the fest and wrote a few prompts, but I'd love it if other people could leave some too. You don't have to commit to writing or drawing anything to leave prompts for other people. I'm definitely hoping to write some Eroica fic for this round of the fest if I can!
