In Aztec mythology, Mictlan was the lowest (ninth) level of the underworld, located far to the north. Except for warriors who died in battle, people who died when hit by lightning and women who died in childbirth, people went 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 Ciucoatl (who commanded Mictlan spirits called Cihuateteo), Acolmiztli, Chalmecacihuilt, Chalmecatl and Acolnahuacatl.
