The tour guide was obviously alarmed when he saw the tribal people who darted out from the forest. There was a reason to it.
These tribal people were actually from a tribe called the Savage Tribe. They were no different from regular humans, looking pretty much the same appearance wise, but their lifestyle was completely different.
The Savage Tribe was used to wearing clothes made out of animal leather and fur; even their weapons were the primitive bows and arrows, as well as long-ranged weapons. They had their own language and they were usually savage like the wild animals.
Although it was known that the Savage Tribe lived in the indigenous forest of Amazonia, the tour guides had never worried about running into them. It was because these tribal people marked their territories. Other than a few parts of the Amazon indigenous forest, they would never intrude other areas.
