The Enipians were a species from the planet Enip. Starfleet Special Operations teams from the USS Prospect and USS Arlington infiltrated sometime in early 2367 in an effort to determine if the Enipians were building weapons to attack the Federation. The mission was a failure, with Kari Eriksson and Vanessa Biondo captured, Daniel Radke and Anne Lansing trapped in the caves under one of the main cities, and the rest of the team dead. (Star Trek: The Prospect Chronicles: "Lady Lazarus") This mission most likely took place between "The Burnt Child" and "Starry, Starry Night".
