Now I know there's no right or wrong about how to depict non-existent species, and it's probably just path dependence at some ;point, but I'm curious to know where it originated. The earliest example I know of personally was Deedlit from Record of Lodoss War, but was it already an established trope at that point?
Was there a Japanese adaptation of Lord of the Rings or something that established the trope? (I have googled but, well, google is terrible now)
Curious is anyone has any insights.
