Steth's ship approaching the Kotaba Expanse.
The Kotaba Expanse is a Delta Quadrant region in or near Benthan space.
In 2374, after Steth had taken over Tom Paris body, he placed Paris into his ship and programmed it to take a coaxial warp jump to the Kotaba Expanse. There, ships of the Benthan Guard arrived to arrest Paris under the assumption he was Steth. (VOY: "Vis à Vis")
