Tlaloc was an important deity in Aztec religion, a god of rain, fertility, and water. He was a beneficent god who gave life and sustenance, but he was also feared for his ability to send hail, thunder and lightning, and for being the lord of the powerful element of water. In Aztec iconography he is usually depicted with goggle eyes and fangs. He was associated with caves, springs and mountains.
Tlaloc was first married to Xochiquetzal, a goddess of flowers, but then Tezcatlipoca kidnapped her. He later married the goddess Chalchiuhtlicue, "She of the Jade Skirt". In Aztec mythic cosmography, Tlaloc ruled the fourth layer of the 'Upper World", or heavens, which is called Tlalocan ("place of Tlaloc") in several Aztec codices, such as the Vaticanus A and Florentine codices. Described as a place of unending Springtime and a paradise of green plants, Tlalocan was the destination in the afterlife for those who died violently from phenomena associated with water, such as by lightning, drowning and water-borne diseases.
With Chalchiuhtlicue, he was the father of Tecciztecatl. He had an older sister named Huixtocihuatl. He ruled over the third of the five worlds in Aztec belief.
