The Jua clan was part of the Jemedari tribe with the entire tribe having over 1 million tribesmen; and while everyone in the tribe spoke the Dari language, there was diversity in dialects and customs. Location was one of the reasons for this diversity as the tribe was spread across not just the Kingdom of Toro but the neighboring countries as well.
There were also different bloodlines within the tribe such as the Mwezi clan, a clan of farmers whose ancestral lands bordered those of the Jua village. The Mwezi clan possessed stronger bodies because of the Celestial Moon Race bloodline flowing through their veins. Despite this, the clan chose farming as their profession instead of combat which disappointed many 'warmongers' in the country.
The Breaking Sun village was the home of Jua clan members in the Eastern Jinfire Nation. This nation was named after Jin Fire or demonic fire but its name had an even grander origin. Jinfire was the name of the 'Human Emperor clan'! The Human Emperor clan that lorded over all humans; the human emperor clan that resided on Purple Mist Star; the same Purple Mist Star that served as the Grand Moon of the Sunken Zika world! This purple planet illuminated the Zika world from an entirely different dimension. This had been confirmed a long time ago after some powerful magicians had attempted to fly across space to reach the illustrious purple moon but no matter how long and how far they flew and no matter how close it seemed, they never reached it. It was a in a wholly different dimension. Eastern Jinfire Nation also referred to as Eastern Jin Nation was named after this massive 'beast' in terms of reputation.
The nation was known to have a lot of demonic warriors due to an unstable gate to the Demon Realm existing there. This gate would constantly spout demonic energy and in some cases some actual demons and demonic treasures would come through the gate. This was both a blessing and a curse but mostly a curse. No amount of treasures could make the constant threat of demons palatable. The nation was also a coastal country connected to the Dream Ocean. As a result, there was a constant stream of foreigners from the Eastern continents arriving at the nation's coast despite the dangers. This made Eastern Jin nation an economic melting place in the entirety of the Sword Scar continent.
However, Eastern Jin was separated from Toro by the Black Dragon Mountains which made travel between the two countries a hassle. There were only two passages between Eastern Jin and the mainland continent with one at the tail, at Dragon Spike which was a border between 3 nations. The other passage was at the Dragon head or the North Dragon location of the Black Dragon Mountains. The Dragon Head was in one of the 3 great nations instead of Toro thus it was much safer than Dragon Spike which was a perpetual warzone. There were also rumors of a secret passage in the form of tunnels that went through the mountains but this was otherwise unproven.
As for going over the mountains, this was basically impossible as one could not climb over them due to the black thunder from the skies. This black thunder was also referred to as Dragon Thunder and was known for being extremely destructive. Even a powerful warrior in the Sky realm could be turned to ashes instantly. The second threat was the Dragon Hell-flame spewing from 'Hell Holes' in the mountains into the sky thus polluting the air and making it lethal to breathe. The scary black-red ash clouds would discourage any climber no matter their strength.
