In the prophecy of Ether to Coriantumr, he said that without repentance the people would be destroyed (see Ether 13:21). According to Joseph Allen, Ixtlilxochitl wrote about the destruction of the first settlers of ancient Mesoamerica:
"In this land called New Spain [Mexico], there were giants, as demonstrated by their bones that have been discovered in many areas. The ancient Tulteca record keepers called them Quinametzin. . . They [the Quinametzin] were destroyed, and their civilization came to an end as a result of great calamities and punishments from heaven for some grave sins that they had committed. (Ixtlilxochitl:25)
