It is within the ability of most educated people on Haven to learn the structure of Koro-go, the Korobokuru language, but about half their vocabulary is incomprehensible to non-Koro. Koro-go has words for colors beyond red, for combinations of magnetic field characteristics beyond just polarity and strength, and for complex emotional interactions. Conversely, the language has few ways to describe deliberate deception, such as lying, because it’s very difficult to do in Koro society.

…these practices hint at the powers that were once possessed by Humans before a planet-wide magical catastrophe changed them forever.

They fearlessly experiment with technology, sometimes just to see what happens. Lutin mages have tried to infuse their machines with magic. Their tinkerers have tried to reverse-engineer alien relics from the Wars of the Fallen Stars. Lutins have developed both steam engines and gun powder. The results of all this tinkering have been mixed, and Lutins haven’t been the only ones who have suffered when their experiments have gone wrong. The easiest way to draw the ire (if not outright hostility) of most other sentient species on Haven is to openly display Lutin technology.

Outsiders who visit Earth sometimes leave behind the odd trinket. Few of these items can be triggered by mere humans; even fewer can be controlled without killing their users or driving them mad; but a very few can actually be reverse-engineered and mated with terrestrial technology.
