The empire in 1539, along with other major players. Note that control over many regions, for all the states or groups shown is spotty at best.
Red is our heroes, the Tawantinsuyu Empire, straddling the Andes, descended from the sun itself. Etc etc.
Light and Medium Blue are various tribes of or related to the Mapuche's, forced to live on the fringes of civilization by Ruminavi's conquests. Of course with the plagues decimating them they aren't doing great, but the Tawantinsuyu are far from home and also plague ridden.
The darkest blue are those Mapuche who refused to live under the shadow of conquest and/or were forced out. They wandered a bit before finding some fertile land filled with weird ass birds.
The yellow is the hated Spanish, they killed the Inca IOTL, prepare to die.
A fine map of the roads the Tawantinsuyu have build, a Roman would recognize them as a hallmark of civilization, but then be confused as to why anyone civilized would live in Mountains that rival the Alps.
The Thin Blue Line is the route nominally given to the Spanish for nominal trading under the Treaty of Cajacamara. Nominally the Tawantinsuyu will provide some protection to the traders who nominally will stay on the path on the nominal pain of death. The Spanish are nominally allowed a permanent presence in the three dots, nominally resting places and missions for missionaries who nominally can stay nowhere else for extended periods of time.
Nominally.
