i don't think it's the word choice per se, it's the construction of impossible-to-remember nonsense titles.
like for example, take "Flameplume Starflowers." I'll give you a thousand Euros if you can remember what that refers to. Is it in a character's skill? Is it the title of a quest? Something you collected in some region?
What about "The Still Water's Flow"? That's the name of a quest. Which questline is that from?
Or "The Heavenly Stone's Debris"?
