Tlalocan
Tlālōcān ("place of Tlaloc") is described in several Aztec codices as a paradise, ruled over by the rain deity Tlaloc and his consort Chalchiuhtlicue. It absorbed those who died through drowning or lightning, or as a consequence of diseases associated with the rain deity. Tlalocan has also been recognized in certain wall paintings of the much earlier Teotihuacan culture. Among modern Nahua-speaking peoples of the Gulf Coast, Tlalocan survives as an all-encompassing concept embracing the subterranean world and its denizens.
