Kurlan

The Kurlans were an extinct species that inhabited the planet Kurl near Federation space. Numerous expeditions were conducted by archaelogists who examined the history of these long dead people.

Findings revealed that the Kurlan culture believed that an individual was part of a community of individuals; each of which had their own voice with their own desires as well as views of the world around them. This resulted in the creation of a form of art known as Kurlan naiskos.

The races history were divided into numerous ages which included the Third Dynasty which was 12,000 years ago. Another age included the Fifth Dynasty. However, the Kurlan species would die several millenia before the 24th century. (TNG episode: The Chase)

The Kurlan homeworld was also an ancient colony of Trill that lived on the planet. They would genetically engineer the Symbiont population which resulted in the creation of the Parasites. (DS9 novel: Trill: Unjoined)


 * Its quite possible that the Parasites were responsible for the destruction of the Kurlan people but to what extent or how this was accomplished is unknown.
