This note is a follow-up, update, and correction of ‘The Union of Two Worlds: Reconstructing Elements of Proto-Athabaskan Folklore and Religion’, published in Folklore in 2016. First, the note addresses evidence presented by a new publication. Next, it adds an omitted illustration of the comparison of a Navajo ‘Big Fly’ with a Tibetan ‘enemy god’. Finally, it corrects a small-but-meaningful error and clarifies a resulting interpretation about the Huns in Buddhist literature.
