This one looks like a lot of fun to me, and I keep forgetting to mention it (it was rydra_wong
's post that reminded me; thanks!): Festibility
. From their prompt post:
Festibility is a fandom festival accepting all kinds of fanworks (fic, meta, art, icons, podfic, vids, recs, picspams, drabble sets etc) about disabled characters. Works can focus on canonically disabled characters or canonically able-bodied characters that you reimagine as disabled. Pieces can be as long or short as you like.The fest is open for prompting/filling prompts until Sept. 15
(and prompts can be filled afterwards, though the commentfic part will be closed). And it desperately needs more Stargate prompts! *puts thinking cap on*
ETA: A non-comprehensive list of canonically disabled characters
; includes lots more in the comments.
