Star Trek: The Cantabrian Expeditions Wiki

The Jenchum were a humanoid species, similar in appearance, but different anatomically and physiologically, than Humans.

The authority overseeing the Jenchum was called the Jenchum Suzerainty. The Jenchum Suzerainty was a part of The Directorate.

Their species were bureaucratic yet honest in nature. Their society was based on a caste system, the artist caste being one such caste.

Some Jenchum had the ability to provide positive emotions and remove negative emotions from another; this ability usually emerged at puberty. This process was called the Thrall, and the type of relationship could be sexual, familial, friendship-based or other in nature, but was normally mutually-exclusive. The Painter was one such person who experienced the Thrall.

One Jenchum colony was on Goffan III, with Enika being a main city and the Terias Provinces being a remote area on that planet. (Star Trek: The Prospect Chronicles: "Starry, Starry Night")
