The Trill government's scientific body, which sent a team under Doctor Lenara Kahn to Deep Space 9 in 2372 to attempt the creation of an artificial wormhole.
The Trill Science Ministry sponsors major research on behalf of the Trill government. In the Deep Space Nine episode Rejoined it dispatches a team to the station to test a method of generating a stable artificial wormhole, using the Defiant as a platform.
The group is led by Lenara Kahn and includes her brother Bejal Otner and Doctor Hanor Pren. The experiments show promise, briefly opening a wormhole before an accident cripples the ship and badly injures Lenara.
The mission is remembered chiefly for what happens around it. The Kahn symbiont was once joined to the wife of Torias Dax, and Jadzia and Lenara find the old love returning, in defiance of the Trill taboo against resuming relationships from past lives. In the end Lenara goes home with her team.
