WARNING: DO NOT INGEST ANY BOTANICAL WHICH YOU HAVE NOT FULLY RESEARCHED AND CORRECTLY IDENTIFIED!!!I am
Teotzlcoatl, older cousin of
Quetzalcoatl. My most famous physical incarnation was
Nezahualcoyotl, but I have taken many forms since the dawn of the cosmos. In this realm I manifest as multiple entities at a single time. I am many, I am numbered. I am few, but more than one. I am a multifaceted being, a winged serpent with many heads. We are Teotzlcoatl.
