I guess I'm in a good mood. I'll give this 5 stars. This story has good writing, nice updates, impressive description, cool characters, and a respectful background for this sort of story.
I invite the author to check out my adventure fanfic "Avatar: The Vindicated Avenger (TLV)". It is a spinoff of "Avatar: Macai's Journey (AMJ)". It might help to read the first 1-3 chapters of AMJ first, but I really don't think that's necessary to enjoy this one.
