Kichwa

The upper Napo country lies east of the Andes, where rivers descend through tropical forest towards the Amazon. Its Kichwa-speaking peoples, also known as Runa, emerged from the histories of several Indigenous communities of the region. During the colonial period the language spread among peoples of the Napo and Pastaza basins, while missionaries used it in their work among the inhabitants of the eastern forests.

The later city of Tena lies here.
