Hey! I just wanted to say that Freefall's story sounds really cool, I'm hooked by the world you've built around them (Downfall quarantine zone? 👀). I'm guessing they're tied in to Hatching a Heist by the Hatchworks connection, is there any more revealed about their story in that quest? Either way, if you plan to post more about them or Downfall, I'll be tuning in with great interest.
Freefall doesn't appear in Hatching a Heist (ao3), sadly. They're in the 80% of the iceberg that's underwater, so to speak. I came up with a lot of ideas for that quest and its setting that will probably never see the light of day because voters chose to go in a direction that doesn't really include them.
It's technically possible that Freefall could show up in the future, but voters have generally been unenthusiastic about the potential story directions that most directly tie Freefall into the plot. (They don't want Whitney-the-fake-cape-criminal to visit a parahuman prison, for some reason!) So I think it's unlikely.
And in the event that Freefall does come up, it will be a long way down the track. Probably literal years away in real time, with how sporadic my updates are, so I wouldn't recommend reading Hatching a Heist in the hope that they'll show up. Sorry for the bad news, it's really nice to have heard that you found Freefall cool.
Downfall is mentioned a time or five, and has had a much more obvious influence on the setting. They're still underwater, but you can see their shape lurking if you look for it. I still wouldn't read Hatching a Heist just for them, but keeping their existence in mind while reading could be a rewarding experience for the thoughtful lore-seeker.
