The Vaskan ambassador who traded with Voyager in 2374 and whom later Kyrian history portrayed as Captain Janeway's partner in a campaign of mass murder.
Daleth is an ambassador of the Vaskans, a people locked in conflict with their Kyrian neighbours. He appears in the fourth-season Voyager episode Living Witness.
In 2374 he arranged a simple exchange with Janeway, offering dilithium in return for medical supplies. During the visit a Kyrian party led by Tedran stormed Voyager, and in the fighting that followed it was Daleth who shot Tedran dead.
Seven centuries later a Kyrian museum presents a very different story, in which Daleth hires a brutal Voyager to wipe out the Kyrians. A backup copy of the Doctor is reactivated there and, with the curator Quarren, reconstructs the real events, forcing both peoples to reconsider the origins of their long grievance.
