Amazonia

Amazonia was a temperate world in the Nuiri sector of the Outer Rim Territories. Its terrain comprised jungles, swamps, large forested mountains, and a massive (though largely unpopulated) ocean that encompassed two-thirds of Amazonia's surface.

History
Amazonia was possibly terraformed by the Rakatans during the rule of the Infinite Empire, explaining the presence of vast forests and wildlife (many of which were recognizable species) prior to the planet's discovery. A primitive tribe of Humans from a nearby world settled Amazonia via an ancient Rakatan colony ship. The tribe gradually grew to the tens of thousands and began forming city-states, though the Amazonians were still extremely underdeveloped compared to some neighboring societies at the time. It would not be until around 400 BBY that Amazonia was discovered by explorers from the Ojoster sector; many of these initial encounters resulted in bloodshed, preventing the arrival of foreign colonists, though an army from a neighboring kingdom did lead a conquest of Amazonia, which introduced several deadly diseases that wiped out hundreds of tribes (these plagues were rumored to have been intentionally spread as a form of biological warfare); many soldiers also conceived children with local women, leading to a vast hybrid ethnicity that became part of the ruling class for centuries onward. Small wars continued between the tribes until the world became a territory of Portugo, after which point it encountered rapid modernization, though poverty, disease, and high crime dominated the Amazonian society.
