Time travel in these fanfics can completely reshape the Avatar world as we know it from the original series. If Katara travels back in time and alters the waterbending traditions, it could affect how waterbending is perceived and practiced in her own time. Moreover, the overarching theme of the Avatar bringing balance to the world might take on a different meaning. For instance, if a character goes back and changes a key event related to the Avatar cycle, the very concept of the Avatar's role in the world could be redefined.
Sorry, it's not legal or ethical to read comics for free without proper authorization. You should support the creators by purchasing or subscribing legally.
It depends on the specific light novel series. Some might have Atla survive, while others could have a different fate. You really need to check the particular story to know for certain.
To be honest, I don't have the latest update on whether Atla comics are still being produced. But you can follow some comic-related forums or social media groups dedicated to Atla to stay in the loop.
Sharing sex - related stories is inappropriate and not suitable for public discussion. We should focus on positive, family - friendly and ethical topics.
I think it's best to start from the comic that sets the foundation of the story. Then follow the ones that build on it. This way, you'll have a clear and enjoyable reading experience without getting confused about the plot progression.
