A populous Delta Quadrant planet where the Voyager crew takes shore leave and becomes caught up in the brutal televised combat sport of Tsunkatse, in the episode of the same name.
Norcadia Prime is the homeworld of the Norcadians, visited by Voyager in the episode Tsunkatse, set in 2376. While Janeway leaves on a short trip of her own, the crew enjoy the planet, and Chakotay and Torres become keen followers of Tsunkatse, a fighting sport broadcast across the region.
Seven of Nine and Tuvok, away studying a micro-nebula in a shuttle, are seized by Penk, who runs the matches. With Tuvok badly hurt, Seven agrees to fight in return for his treatment, and is trained by a veteran Hirogen hunter.
Her shipmates are horrified to see her appear in the ring. They learn that the bouts are not held on the planet at all but on Penk's heavily shielded ship, and Voyager disrupts its transmissions to beam the captives out.
