The legend of agave, according to the Aztecs.
The Aztecs believed that since the beginning of time there was a goddess in the sky. Tzintzimitl, an evil goddess that devoured light. She had the earth in darkness and forced the natives to do human sacrifices in order to give them sunlight.
Quetzalcoatl had enough and decided to do something about it. He believed in honor so he ascended to the sky to fight Tzintzimitl. But instead, what he found was that Mayahuel, his granddaughter was kidnapped by the evil goddess. Mayahuel is the goddess of fertility, she was portrayed as the goddess with four hundred breasts. Quetzalcoatl found her and fell in love with her so instead of killing the evil goddess he and Mayahuel descended to earth to live together.
When Tzintzimitl realised, she got pissed off and went for them. They were forced to run from one place to another to hide from her. One day they decided, because there was nowhere to hide, they would disquise themselves as branches of a tree. The two stood very close together, so that when the wind blew their branches would touch and they would comfort each other.
Tzintzimitl however did not give up that easy so she used her light and created stars. Finally Mayahuel got recognised and Tzintzimitl descended and tore Mayahuel in to pieces. Quetzalcoatl, was heartbroken and furious so he buried the pieces and flew up in the sky and killed Tzintzimitl. He was staring at the sun rising, crying, thinking of his loved one. Every night he would go to her grave and cry. The other gods saw how miserable Quetzalcoatl was, At her grave a plant started growing up, and they decided to make him a gift. They gave the plant hallucinogenic properties that would comfort Quetzalcoatls soul, so that from that day on he could always find comfort.
A rainy and stormy night many years later when Quetzalcoatl was at her grave, Mayahuel sent a lightning strike from the sky straight down into the agave plant. The agave opened up and was steaming hot inside. The sweet smell and the honey golden color of the agave made Quetzalcoatl taste it, he never tried anything like it. So every night when he came back, he would eat of the plant. The plant quickly fermented in the open air and Quetzalcoatl found comfort.
