A leading figure at an outpost of the Mikhal Travellers who distrusts outsiders and is slow to share his people's knowledge of the space ahead with Voyager.
Nakahn is one of the Mikhal Travellers, a loose community of explorers who trade stories of their journeys. He appears in the third-season Voyager episode Darkling.
When Voyager stops at the Travellers' outpost in search of information about the region ahead, Nakahn deals with Captain Janeway. He is guarded and rather scornful of his more romantic colleague Zahir, who has caught the eye of Kes.
After Zahir is attacked and thrown from a cliff, Nakahn's suspicion of the visitors hardens. The culprit turns out to be the Doctor, whose programme has been warped by personality subroutines borrowed from historical figures.
