Tezcatlipoca - The Smoking Mirror.

Huitzilopochtli's rival as the most important Aztec god was Tezcatlipoca, the god of the night sky, ancestral memory and time. His nagual was a jaguar. Tezcatlipoca was one of the most important gods of the Postclassic Mesoamerican culture and the supreme deity of the Toltecs, the northern Nahua-speaking warriors.
The Aztecs believed that Huitzilopochtli and Tezcatlipoca created the world together. However, Tezcatlipoca was an evil force often associated with death and cold. The eternal opposite of his brother Quetzalcoatl, the Lord of the Night carries an obsidian mirror. In the Nahuatl language, his name translates as “smoking mirror”.
