Prema II was a Delta Quadrant planet with a Talaxian mining settlement, whose convoy joined Tom Paris in 2373 to help recapture Voyager from the Kazon-Nistrim.
Prema II is named in the two-part story Basics. As Voyager heads into a trap laid by Seska and Maje Culluh, Neelix suggests calling on the Talaxian colony there for support, since its ships are close enough to reach them.
The Kazon seize Voyager before help arrives and maroon the crew on Hanon IV. Paris, who had left by shuttle just before the takeover, makes his way to the Talaxians and persuades their commander, Paxim, to join an attack.
With the Doctor and Lon Suder sabotaging the ship from within, the small Talaxian fleet and Paris's shuttle disable Voyager's defences. The Kazon abandon ship, and Paris retrieves the crew.
