I read a fanfiction by Cassidy Alice entitled "The Calm Before the Storm" Link here - [link]
It is AMAZING. She is such an amazing writer and it's so sweet. Basically, it's a younger Korra (six years old, like we saw her in the beginning of the show) going with our new elderly Katara to a hill. But not just any hill. The one where Aang and Katara first went penguin sledding. Then, Korra asks Katara if she wants to go penguin sledding with her, and Katara has a flashback. It's really sweet :')
So, I was inspired to draw this....It's so sad. I wish Aang could be there with her to just give her a big hug!
I hope you enjoy it, it took about 5 hours to do
Edit: Some of you may have noticed how Katara's necklace lacks...anything on it. And, if you did not notice this, you are noticing it now. You see.....um.... it has nothing there...because....over the years....she's rubbed it down to smoothness....nothing remains.... heh...heh..... I'll fix it later.
