In Far Fetched Fables 178, the story is “Mouth of the Jaguar” by Evan Dicken. This story had a lot of Azteca wording, including one word I hope never to have to pronounce so many times in a short span again: macquahuitl. It is an impressive weapon as described, but it’s a bear on the pronunciation of any word following it!
