It is said the mighty feathered serpent god, Quetzalcoatl, helped create the earth. He is the hero who stole back the bones of humanity from the evil god of the Underworld. In his quest to bring humans to the earth, Quetzalcoatl's dog-headed twin brother, Xolotl, was present. Not much is known of Xolotl, the god of lightning, death, and misfortune. A monster.

This is what really happened.
