In Aztec religion, Ītzpāpalōtl was a striking skeletal warrior and death goddess and queen of the Tzitzimimeh "star demons", who ruled over the paradise world of Tamōhuānchān, the paradise of victims of infant mortality and the place identified as where humans were created. She is the mother of Mixcoatl and is particularly associated with the moth Rothschildia orizaba from the family Saturniidae. Some of her associations are birds and fire. However, she primarily appears in the form of the Obsidian Butterfly.

Aztec mythology is the body or collection of myths of the Aztec civilization of Central Mexico. The Aztecs were Nahuatl-speaking groups living in central Mexico and much of their mythology is similar to that of other Mesoamerican cultures. According to legend, the various groups who were to become the Aztecs arrived from the north into the Anahuac valley around Lake Texcoco. The location of this valley and lake of destination is clear – it is the heart of modern Mexico City – but little can be known with certainty about the origin of the Aztec. There are different accounts of their origin. In the myth the ancestors of the Mexica/Aztec came from a place in the north called Aztlan, the last of seven nahuatlacas to make the journey southward, hence their name "Azteca." Other accounts cite their origin in Chicomoztoc, "the place of the seven caves", or at Tamoanchan.
