Reading some late 50s French sci-fi, wondering if this jungle world being fought over by powerful alien civilizations (Human & other) is a thinly-veiled reference to French Indochina. Then I notice that the name of the semi-mythological king who reappears out of the ancient past to kick all the offworlders' asses, "Safass-Thin", rhymes with "Ho Chi Minh".
So there's that.
(Same author wrote the book that Fantastic Planet was based on.)
