Toromona is an Indian tribe in South America that belongs to the group of uncontacted people. No non-Natives have contacted this tribe. During the Spanish colonization, Spaniards found it difficult to settle down in the area of the Amazon, where their main goal was to find a secret place called Paititi, an alleged hiding place of the Incas' biggest treasures that the Incas concealed from the Spaniards. There are some historical records that confirm that the Incas sealed subterranean tunnels in ritual ceremonies. Father Miguel Cavello Balboa wrote about a city of gold and he described Paititi as a place protected by warrior women; he also mentioned the Toromona tribe with notes that it had no mercy in killing.
A Norwegian biologists, Lars Hafskjold, searched exhaustively for this ethnic group (Toromona) and became quite famous by his disappearance (1997) somewhere in the region of the Madidi park.
