Marna was a photometric projection of a Vori female, part of a training simulation of the Vori Defense Contingent.

Marna was an inhabitant of the Larhana settlement and along with Karya and Penno, she greeted Commander Chakotay when he came to their settlement. Chakotay was not aware, that drugs and photometric projections were used to train him for the Vori Defense Contingent in their battle against the Kradin.

When Chakotay asked for a way to communicate with the USS Voyager, Marna told him that the Kradin had taken away all their machines. When the Kradin took several inhabitants of the settlement to the extermination facility, Marna told Chakotay what would happen to them. (VOY: "Nemesis")
