A Delta Quadrant trading species with a strict system of justice, one of whose weapons dealers, Kovin, was accused by Seven of Nine of assaulting her in 2374.
The Entharans are a humanoid species of merchants who appear in the Voyager episode Retrospect. Voyager visits their colony to buy an isokinetic cannon from Kovin, an abrasive but talented arms dealer.
After Seven of Nine strikes Kovin, the Doctor helps her to recover what seem to be suppressed memories of Kovin stunning her and removing Borg nanoprobes. Under Entharan law even an accusation can ruin a trader, and a magistrate is called in to hear the evidence.
The examination of Kovin's workshop fails to support the charge, and it becomes likely that the memories were unreliable. Kovin, already in flight, refuses to believe Janeway's assurances and overloads his ship's weapons, destroying himself. The Doctor is left shaken by his part in the affair.
