Here it is an introduction of this world so you can understand what is coming next.
ORIGIN
Once upon a time, according to ancient ages, there was a land where arrogance and power corrupted mankind.
The Earth was divided in four great continents,from North to South, and from East to the West. Lagonia, the land of lochs, Tersia, the continent of those who have smooth skins, Aggregated Kingdoms ruled by the king Brabante, and The Dark Lands, where it was said its forests were so lush that you couldn't see the sunlight. So everything was dark.
The economics were based on trades and conquests. Tersia was known by its numerous population, the tersians, and its trades with Lagonia for raw material such as iron for weapons, hardwood for forniture, the most pure breeds of horses, the greatest quarries... everything that was useful to trade with was commercialized by tersians to increase their wealth and power.
It was known that the king Brabante was jelous of Tersia's power, that's why he looked for new trade routes, but tersians were well settled in Lagonia and there was no place which were not controlled by them.
Then, a strong rumour about all raw materials that could be found in The Dark Land was being increased. But the king was not a fool, and he knew the danger of carrying troops to that unexplored area. That's why he conjured the Goddess Earth to provide him with so dark skin men that they could be able to camouflage in the night. And the Goddess agreed. She provided him with dark skin soldiers. Rude and brave men who were able to achieve every single thing that the king asked them for. Such was their efficiency that they were known under the name of Bravatos. The king marched to the North, and even though his incursions stayed in the frontier and they had to come back pretty early because of the hostile terrain, he had found something more valueble than he had expected at the beginning, a commerce than tersians had not exploded yet, the trade of enslavement.
They got very few of these slaves before being driven out by other tribes, only 500 of a unknown race until that moment. They were similar to lagonian race, they were white, but they differed from them because their skin was made from the Moonstones, their eyes were clearer, and all of them had golden hair. It was obvious, their race was lower. If the Goddess Earth had liked them, they would have been a little bit more similar to the residents of Aggregated Kingdoms, or at least similar to the tersians. There were not doubt that the Inmolated God, the Sun, didn't like them either. Their skin could get burn pretty easy, and that was something not so usual in Tersia or Aggregated Kingdoms. That was a proof of their superiority. But even if they were superiors to this new race, they need to keep a thriving race of slaves. They mixed this 500 slaves with the ones they had bought in Lagonia in order to keep the dirt of their race for serving the needs of the real humans. In honor of this magnificent breed of slaves, the Aggregated Kingdoms became known as Bravatonia.
