The D’Arsay were an alien race who existed 87 million years ago. They built the D’Arsay archive which was discovered by the crew of the USS Enterprise-D in the center of a rogue comet in 2370.

The archive contained records of artifacts and personalities from D’Arsay mythology.

Using the ship’s replicator, the archive transformed parts of the ship. The archive also altered the positronic brain programming of Lt. Commander Data to take on multiple personalities from the civilization and mythology.

Deltans are known for their peaceful, unified culture, emotionally balanced nature and open sexuality. Deltans were best known for their high sexuality, both sexes emitted some of the most potent pheromones known to Federation science. As a result, Deltans were something of natural aphrodisiacs, with a strong effect on most humanoid species. Deltans who serve in Starfleet are required to swear an oath of celibacy to protect their crewmates from this effect.

Denobulans typically preferred to be among large groups and found solitude uncomfortable. However, Denobulans, at least males, were uncomfortable being touched by persons they were not intimate with. Denobulans were typically polyamorous, where a man typically had three wives, who each had three husbands. This created extremely large extended families; Phlox had 720 familial relationships, 42 with sexual possibilities.

Denobulans were typically very patient. The species was renowned for having this quality in abundance. They only require six days of sleep per year (though, according to Dr. Phlox, two will suffice).

Devidians’ only useful form of nourishment was Human neural energy. They acquired this energy by draining the subject of their neural energy, killing the subject.

The Dosi placed great importance on business and were extremely aggressive negotiators, to the point that fatalities were not uncommon.

In 2370, Grand Nagus Zek had Quark open negotiations with the Dosi for tulaberry wine, although Zek’s real goal was to get the name of a contact in the Dominion so the Ferengi could open business negotiations with them. Quark and Pel negotiated with Inglatu and Zyree on Deep Space 9 and later on the Dosi homeworld.

The Douwd were a powerful, immortal race made of pure energy. Capable of creating disguises and false surroundings by manipulating matter and energy. They have the ability to create and destroy on an epic scale.

Only one individual from the Douwd race has been encountered, a being who referred to itself as Kevin Uxbridge while in Human form. Living in human form and hiding his true identity he married Rishon (a human). When was Rishon 77 years old the couple moved to the Federation colony on Delta Rana IV.

In 2366, a warship belonging to a vicious species known as the Husnock attacked the planet. As Kevin possessed a pacifist conscience, he refused to destroy the Husnock attackers outright, instead trying to scare them away with false images. Instead of fleeing, however, they became “angrier and more cruel”, laying waste to the planet. Finally, Rishon left Kevin’s side and joined the fight against the Husnock perishing with the other colonists. When Kevin found her body, he lost control of his emotions; in a fury of blind rage, he summoned his powers and destroyed the Husnock completely, all fifty billion of the species. When Kevin regained his senses and realized what he had done, he was horrified. He used his powers to recreate his house and Rishon, then sentenced himself to exile as the only living being on Rana IV.
