Selelvian

Memory Beta, the wiki for licensed Star Trek content.

The Selelvians were a race widely regarded as one of the mosty beautiful in the galaxy. Due to their resemblance to creatures of Earth mythology, humans gave the species the nickname of "elves". The Selelvians posessed a mental manipulation/control ability that the Selelvians referred to as the "Knack". The Selelvians were a member of the United Federation of Planets until evidence that Selelvian delegates were using the "Knack" to manipulate Federation council procedings was uncovered in 2376. This lead to the Selelvian War (NF novel: Stone and Anvil)

In 2365, a Selelvian civilian named Jaan Devin who was living onboard the USS Enterprise (NCC-1701-D) was diagnosed with an incurable degenerative illness found only in Selelvians known as the Rot.

Jann betrayed the Enterprise to the Kreel named Aneel after Aneel claimed that he knew of a cure for the Rot. Aneel lied to Jaan about the cure, and killed him shortly after Jaan led him to the bridge. (TNG novel Strike Zone)

In 2377, the Federation starship USS Trident (NCC-31347) had several encounters with Selelvian renegades after the Selelvian Gleau was killed on that same starship. The Selelvian government demanded that Janos, the Excalibur crewman who had been accused for the murder, be turned over to them. (NF novel: Stone and Anvil)

Elizabeth Shelby, as commander of the USS Trident, was instrumental, together with the USS Excalibur and the USS Enterprise were key to the revelation of Selelvian telepathic manipulation of the Federation Council. This revelation lead to the Federation revoking Selelvia's membership. In retaliation, the Selelvians allied themselves with the Tholian Assembly and a short war between the Federation and the Selelvians was the result.
