Quinametzin existed during the previous Suns or Sun, not the current one. Depending on the tradition or who you ask, they are mostly associated with either the first or the second sun. Now, let me explain, the Nahua cosmology is a different concept than most would think about cosmology today. They believe our world is going through cycles and the sun is just a star in the sky, but the framework for our system, representing a complete cosmic age, or the way reality works.

 All of the creatures that I may mention in these myths are not necessarily dragons as we would think of them today. Most of them will share the same lineage, so I will save time on speaking about the lineage after the first few. Just know that they are most likely the offspring of Gaia or Typhon and Echidna (uh-kid-na).
