In Aztec paganism, Mictlan is the lowest (ninth) level of the underworld, located far to the north. Except for warriors who die in battle, people who ar killed by lightning and women who die in childbirth, all people go to Mictlan after death. The journey was difficult and took four years, but the dead were aided by the psychopomp, Xolotl.
The king of Mictlan was Mictlantecuhtli. The queen was Mictecacihuatl. Other deities in Mictlan included Cihuacoatl (who commanded Mictlan spirits called Cihuateteo), Acolmiztli, Chalmecacihuilt, Chalmecatl and Acolnahuacatl.
