"Throughout the battles with the Spanish, the Aztecs still practiced their traditional ceremonies and customs. Tlapaltecatl Opochtzin [actually of Coatlan] was chosen to be outfitted to wear the quetzal owl costume. He was supplied with darts sacred to Huitzilopochtli, which came with wooden tips and flint tops. When he came, the Spanish soldiers appeared scared and intimidated. They chased the owl-warrior, but he was neither captured nor killed."
