Reviews: Rokus Comet
Progeny Ex Machina's review
The title alone should give away where this one-shot eventually leads. As in canon, Roku shoots down Sozin's proposal to conquer the other nations and thus unite the world, but he doesn't stop thinking about it. The death of his best friend, implied to be from battle wounds, finally leads him to choose nation over duty. The premise is unique, the tone is chilling, and the implications carry far beyond the end of the story.
