Hey guys! Since Book 3 is over and I’ve been gaining new followers, I decided to make a masterpost with all the links and information you need. I may have forgotten something, if some of your questions weren’t answered, feel free to message me. I hope this post is helpful. Thank you all for sticking with me for two years, I am really grateful for each one of you guys!
Is Book 3 the last season of TLOK? No. There’s still a Book 4, it was confirmed by Michael DiMartino, one of the co-creators of the show. You can see his confirmation here.
When does Book 4 come out? There isn’t a release date yet. But it’s likely to come out next year. Here's all we know about Book 4 for now.
Why doesn’t TLOK air on Nickelodeon anymore? It moved to digital because of the amount of people who were already watching it online. Korra has a big online fanbase and they decided to post the episodes online. More information here.
Will you make an A:TLA masterpost? There’s already an A:TLA masterpost that includes comic downloads, you can find it here.
