Hey folks, there is a moderately active asoiaf Lemmy community at @asoiaf. Lemmy and Kbin are the fediverse reddit clones. If you give it a follow, it should pop up new posts in that community into your home feed here on Mastodon. It's one of those fediverse tricks you can't do on Twitter and Reddit. You can comment on those posts from here, too. You just won't be able to create new threads there without creating a Kbin or Lemmy account.
