I know about the 5 different ages, with a different deity over each one, but some of what you mentioned is unfamiliar. Do you have a good link to more info on this that you can share?
Most of what I know is either from direct contact with profesors who study it, sources in Spanish and plain growing up in here.
However, I find this site particularly complete
Aztec Mythology
It is only missing a few things here and there. If you read carefully, you'll start noticing contradictions, most of them around the properly aztec pantheon. How is the moon both Tecuciztecatl and Coyolxauhqui's head? How is Huitzilopochtli both the last son of Ometecuhtli and Ometecihuatl and the child of Coatlicue by immaculate conception? Why does he suddenly become the Sun God with no explanation? How is Tonantzin the mother of the gods if Ometecihuatl is the literal mother of the creator gods?
Once you start learning more about the panculture of the anahuac, even more contradictions show. The rule of four is very common, however when they are assigned colors, the colors are red, black, white and
yellow. The role of Huitzilopochtli as blue Tezcatlipoca is completely out of pattern. More so, he suddenly shifts from creator of animals/plants (It is different depending on the retelling and whether Xipe Totec- agricultural god- or Mixcoatl as Camaxtli -a hunting god- is kept instead) to warrior, bringer of light and sun god. And this is because the aztecs were in essence outsiders and impossed their own gods over the existing pantheon before they arrived and recast some of them in important roles. Not even the other Nahua people worshipped Huitzilopochtli. Sadly, a lot is lost because only the aztec myths were preserved as much as they were. However we can learn a lot because the truly pregispanic codices we know are mostly done by Mixtec tlacuhilli, but the lore to fully read them is lost.
