according to the aztecs, where do people travel to after they die?

Direct answer: In Aztec belief, most souls travel to Mictlán, the underworld, after death. Some deaths lead to different destinations: for example, those who died in certain ways (like drowning, lightning, or illness associated with water) could go to Tlālōcān or Tlālōcān-related realms, while others might be guided to more favorable places such as Tlālōcān, Mictlān, or other divine realms depending on the manner of death and the gods involved. Overall, Mictlán is the common destination for many people, but multiple afterlife destinations existed in Aztec cosmology, reflecting the cause or manner of death and the gods’ determinations.
