Ren and Mizu. Sisters who's parents have died. Orphans out on the street. Ren, 17, and Mizu, 14, have to survive any way they can. Ren being the oldest has two jobs to get money to buy food, but doesn't make very much. The avatar has long last and new trouble stir in republic city. But will the new avatar be found? Will they step up and do their job?
The next avatar after Korra, has a secret. Her and her sister live in an abandon school a few miles into the woods away from the city. She knows of her abilities but keeps it to herself for reasons you can only find out by reading.
With a very observant sister, she has to watch her back to make sure she doesn't find out. Will she manage to hide this big part of her? Will she step up to her responsibilities? Will someone she loves get in trouble and force her to use it to protect the ones she cares about? Or will she stay in hiding and let the chaos in republic city continue to rise.
This story will have swears, may have some violent and graphic scenes, Sexual content, and maybe some trigger warnings. Im not sure I haven't played every detail out yet it all depends on what ideas come to mind.
Keep in mind, Korra is gone (sadly) but some of her friends are still around. Maybe this avatar will have connection to Korra? We'll see!
