Nori (Ilari)

From Memory Alpha, the free Star Trek reference.

Nori was a female Ilari. She was spouse to Tieran, a tyrant who had the ability to transfer his consciousness to another's body. When the ship she and Tieran were on exploded, they were beamed over to USS Voyager. Tieran died, but not before transferring his consciousness to Kes. She helped Tieran escape from Voyager and stayed loyal to him even after he decided while he was in Kes' body to marry another for political purposes.

Nori was killed by Tuvok after she fired upon the rescue party during the attack to free Kes. (VOY: "Warlord")
