[So many questions. Well, an inquisitive mind is the sign of someone bright.]

My homeland is called the Fire Nation. Firebenders, like myself, come from there.

I cannot really say why there is a war. My grandfather believed that it was the best way to share our nation's prosperity with the rest of the world. My brother seems to believe similarly, but it is a simple show of power, nothing more. My brother does not understand what it means to live in unity with others, and that pains me.
