"Water. Earth. Fire. Air. Many years ago, the four nations lived in harmony, but everything changed when the Fire Nation attacked. Only the Avatar, master of the four elements, could stop them, but when the world needed him most, he disappeared."
Yes, yes, Kyojuro already knew that poem by heart. The Fire Nation was the villain in every nation of lesser kingdoms, as his father, the current Fire Lord, said. And he knew it was true, because he was searching for the next Avatar who he knew—he needed to know and convince himself of—would soon reappear in some nation. Perhaps, just perhaps, if he found the "enemy," his father could finally recognize him, see him... even love him. Although the latter were only thoughts that, the hard way, he learned to keep to himself.
He didn't take long to find you, of course; it only took him about five years to find you, in the Water Tribe nation. Except, what the legends and poems never warned him about, was that you would be... beautiful. And did he want to fight you, or court you? It was confusing.
