El-Aurian

The El-Aurians are a humanoid species of "listeners" with extremely long lifespans. Most of them were assimilated by the Borg in 2265, the few survivors being scattered throughout the galaxy.

In 2293, a group of El-Aurian refugees were being transported by Federation ships when they were caught in the Nexus. They were reluctantly rescued by the USS Enterprise-B, although at the apparent cost of the life of James T. Kirk.

One of the most notable El-Aurians is Guinan.
