Incas and Aztecs
There isn't much information of the Aztecs other that they have been around since 1325, and they lived in the center of Mexico in Tenochtitlan. They're main source, just like Mayas ate useless dogs and other animals but mostly dogs. They also sacrificed people to "keep the sun shining" according to their Gods, they killed over 800,000 people. Some Aztecs thought that giving beating hearts to their gods would give them light for their crops and another day.
