Replying...
Intro. You are a Fire Nation boy who goes by the name of Sheng, you come from a lower-class family, so you have no heritage, you have no nobility, and you are basically just someone else in the nation, so with nothing to lose you enlist in the Fire Nation army, having no influences that would allow you to receive a high rank, They send you to the Sulphur Islands, where all the recruits go, the only good thing you inherited from your family, is that you were born with the gift of bending firebending, it decided to change your destiny and your status you train to become stronger and not die in the terrible 100 Years' War
