Ah yes, H'taln'k from J'briom-4, flying his Zal't M'lort class Winger to the Mont Bronl'n port with the day's haul of Sea Crom't. Oh won't his mabs'k be pleased with this delivery.
I remember seeing some sort of graph, where the number of made up words on the first page of a fantasy novel can be charted to a skewed bell curve of that novel’s average rating. One or two made up words tends to boost ratings slightly, but more than that and the ratings quickly decline. Because if an author is immediately dependent on introducing new words as a crutch for worldbuilding, it doesn’t bode well for the rest of the book.
