A conversation in Hharmari.
In The Golden Net, Hharmari is framed as a current day, stable language that was born out of a much older pidgin language. This pidgin language was used by fishermen, seashell divers, and people who traded with them in a fictional version of the coastal areas around the Pyrenees.
The language mainly pulls from Spanish, Basque, French, Catalan, and Occitan for its vocabulary and grammar, though it also has some features from other languages, like ideophones and large compound words (both ones that have arisen naturally, and ones used for artistic effect.)
The story text does not feature the language directly. Instead, the writing style uses some of the features of the language—namely compound words—to make the sensory descriptions more vivid, strange, and kinetic. Some illustration titles are also written in Hharmari, like Hharil d'Ex, Term d'Uta, and Ne merluch k'z'ehhisa.

Why develop a whole language if it's not directly featured in the story text, though?
