Allan, I have yet to dig into my files in the garage, I have only looked online and in my active files in the house. This is what I have determined thus far. Xilonen, Xipe, Kalka-killa, and others in the tomb are not the gods, only representations of the gods used by the priests of Zotz. They are only creatures/monsters. Most of the names relate to specific gods in the Olman pantheon however. Kalka-Killa, Chitza Atlan, and Nanahuatl were made up names derived from actual deity and Mezo-american site names, but did not relate to a specific name. Kalka-Killa was derived from a couple Incan deities - Mama-Quilla and Ka Ata-Killa - both are Moon Goddesses. In the references I located, they are listed next to the Crabman in Inca statuary. Since the zodiac sign for the moon is Cancer, the Crab - I was inspired to make this representation a giant hermit crab. Chitza Atlan is essentially the guardian of the dead, sort of the mesoamerican equivalent to Charon the boatman. At best, he is a demigod. This centaur mummy is not actually a centaur, but a taxidermical contrivance stitching the torso of a man to the body of a horse. Technically, it should not even be an equine body, since the mesoamericans did not possess horses, so it is more likely a llama or large white tail deer body (or moose or buffalo). Nanahuatl was a blank faced creature that was to represent the every man, but was essentially a variation on the doppleganger. This is at best a lesser god and at worst a common monster. By the way, Zotzilaha really means "cave of the bats" and referred to the home of the Zotz or Camazotz which by mythological description fit our more Anglican depiction of a vampire. Camazotz may be one creature, but more likely it represented a type of legendary monster race, like the harpies or original gorgans which were a finite number of individuals. In Mesoamerican lore Zotzilaha may be the birth place/parent of Camazotz. I will keep looking for my original source documents to see if there is a greater clarification, but for now I think this should satisfy your gamer's query.
