For my Digitober 2020 I decided to investigate different characters from Mayan Mythology, most of my references are from:
-Popol Vuh
-An Illustrated Dictionary of the Gods and Symbols of Ancient Mexico and the Maya by Mary Miller and Karl Taube.
-The Oxford Companion to World Mythology by David Leeming
-A lot of Wikipedia pages :)
