The Nyrians did not consider themselves a cruel people, and went to great lengths to avoid warfare, but nonetheless acquired new ships, colonies and space stations without consent of their previous owners. Ships so acquired might be tasked with defending Nyrian acquisitions. In 2373, the Nyrians attempted to take control of the USS Voyager using their translocator. The Nyrians gradually exchanged themselves for Voyager crewmembers at the rate of one every 9 minutes and 20 seconds, and put the Voyager crew in an Earth-like habitat on board their biosphere vessel.
