Mictlan was the underworld of Aztec mythology. Most people who died went to Mictlan, although other possibilities existed (see "Other Destinations," below). Mictlan, far to the north,, consisted of nine distinct levels.
The journey from the first level to the ninth was difficult and took 4 years, but the dead were aided by the psychopomp, Xolotl. The dead had to pass many challenges, such as crossing a mountain range where the mountains crashed into each other, a field with wind that blew flesh-scraping knives, and a river of blood with fearsome jaguars.
Mictlan also features in the Aztec creation myth. Mictlantecuhtli set a pit to trap Quetzalcoatl. When Quetzalcoatl entered Mictlan, Mictlantecuhtli was waiting. He asked Quetzalcoatl to travel around Mictlan four times blowing a conch shell with no holes. Quetzalcoatl eventually put some bees in the conch shell to make sound. Fooled, Mictlantecuhtli showed Quetzalcoatl to the bones. But Quetzalcoatl fell into the pit and some of the bones broke. The Aztecs believed this is why people are different sizes.
Mictlan was ruled by King Mictlantecuhtli ("Lord of the Underworld") and his wife, Mictecacihuatl ("Lady of the Underworld").
Other deities in Mictlan included Cihuacoatl (who commanded Mictlan spirits called Cihuateteo), Acolmiztli, Chalmecacihuilt, Chalmecatl and Acolnahuacatl.
