Sun Warriors (Earth-1529)

The Sun Warriors are an ancient civilization who were the first humans to discover firebending from the near-extinct dragons. The precursors to the modern-day Land of Fire, most of the world believed they had died out thousands of years before even the Warring States Period. However, a small civilization of them lived on in secrecy near the ruins of one of their ancient cities, where they retained their cultural and philosophical traits.
