Attention Aztecs!
Meet Elena Torres. Back when she was a young, impressionable college student, she met Tezcatlipoca, and he rocked her world. Now she's the leader of a cult worshipping the old gods of the New World, especially the Aztecs (though she fangirls Coyote pretty hard...).
She's newly arrived to New York, and Quetz runs into her here. Although she didn't mention it to Quetz since he outed himself as human sacrifice hating hippie, she and the cult members are more than willing to do some human sacrifice if their gods so require. Plotting would be awesome!
