Yridian

The Yridians were a warp capable race in the 24th century. They were regarded as information merchants and smugglers, and were generally considered devious and untrustworthy. (TNG: "The Chase"; DS9: "Facets")

Physiology

Yridians were humanoids who were usually bald, others had black or brown curly hair. They had wrinkled skin. They also had large rodent-like pointy ears but small eyes and noses. All Yridians had an indented ridge running across the full length of their heads and extending down their nose. Most Yridians had no thumbs, and possessed only four fingers on each hand.

The actors wore a glove, that covered their index finger and thumb, making it appear to be one large finger. These four-fingered hands can be seen in close-up in "Birthright, Part I", "Firstborn", "A Simple Investigation", and "Business as Usual". There are two exceptions, one is Ashrock, the other is Yranac, but they have other small changes such as hair and a darker complexion. They may be a sub-species of Yridian.

History and politics

It was not known if the Yridians had a central government. The Yridians encountered by the Federation appeared to be loosely aligned and concerned with their own interests, often serving as hired agents for other races and operating as groups or individuals. (TNG: "The Chase") They were often unwilling to reveal information they collect without payment. Despite their reputation, the Yridians were often seen on space stations and planets within Federation space. (TNG: "Birthright, Part I", "Gambit, Part I"; VOY: "Non Sequitur") However, the shady dealings of some Yridians earned them arrest warrants issued by governments such as the Klingon Empire (TNG: "Gambit, Part I") and their trading goods were often confiscated. (DS9: "Facets")

In an alternate timeline the first Human encounter with this race took place during the 2160s when explorers found notes about the Yridians in the Vulcan database. (ENT: "Twilight")

At some point before the 2360s, the Federation believed that the Yridian race went extinct. This disappearance was so total that it even convinced the Borg, who designate the Yridians as Species 6291, that the species was no longer in existence. However, Rudolph Ransom, a Starfleet exobiologist, discovered that there were some still alive and carried out First Contact. This act directly led to his promotion to the rank of captain. (VOY: "Equinox")

The strange extinction of the Yridians can be explained by assuming that some natural (or unnatural) disaster befell the race sometime between the 2150s and the 2360s. It is possible that the group later encountered by Captain Ransom had not had previous contact with humanity and therefore counted as a true first contact. Presumably the numbers of Yridians are still very low.

Yridian script

After this point Yridians were encountered throughout Federation space. A group of Yridians learned of the research of Dr. Richard Galen sometime prior to 2369. The Cardassian Gul Ocett purchased the information they had obtained, and the Yridians later attacked Galen's shuttle to steal further data. Their ship was destroyed by the USS Enterprise-D before it could return to the Cardassians with its findings. (TNG: "The Chase")

A group of Yridians bought magnesite ore, stolen from a Pakled mining colony in the Kalla system, from the Duras sisters in 2370. (TNG: "Firstborn")

The Yridians were known to be targets of Maquis raids in late 2370 as Starfleet put together a Yridian convoy as lure for a Maquis attack. The convoy of six ships left Deep Space 9 for the Demilitarized Zone, destined for Cardassian space, carrying a supply of isomiotic hyposprays, plasma flares and quarantine pods. (TNG: "Preemptive Strike")

This also indicates that it was not uncommon for the Yridians to carry supplies through the DMZ and that they had a political relationship with the Cardassians.

An unnamed Yridian had dealings with Elim Garak, and in 2371 Garak identified the Yridian as someone who would want him dead. (DS9: "Improbable Cause")

Two Yridians used a gravimetric scanner to cheat on Quark's dabo table in 2373. (DS9: "Nor the Battle to the Strong")

An Yridian worked for Quark in 2373. (DS9: "Business as Usual")

In early 2374, during the Dominion occupation of Deep Space 9, an Yridian was seen in Quark's. (DS9: "Sons and Daughters")

Culture

A Yridian called Paltriss created several rings, later known as the Rings of Paltriss. They became extremely valuable and, as such, were removed from the Yridian homeworld over time. In 2370, Quark came into possession of forty-two of them. (DS9: "Melora")

The Yridians exported several beverages to the Federation, Klingons, and Ferengi, including Yridian tea, Yridian ale, and Yridian brandy. (TNG: "Eye of the Beholder"; DS9: "The Sword of Kahless", "Who Mourns for Morn?")

The Yridian yak was also well known. (DS9: "Accession")

Technology

Yridian ship

The Yridians operated their own design of starship, used as both a destroyer and as a freighter. (TNG: "The Chase", "Firstborn") Others were known to operate small warp capable shuttles. (TNG: "Birthright, Part I")

Background information

A Yridian was briefly considered as a regular character on Star Trek: Voyager. (A Vision of the Future - Star Trek: Voyager, p. 177)

Apocrypha

The conversation between Quark and Ashrock in "Melora" suggests that the Yridians do have a homeworld, referred to in the DS9 novel Hollow Men as Yridia.

In Star Trek Online, the Yridians are a minor non-playable race. They are currently in game as opponents in a few missions, or as crew on the player's ship.
