Elieth was a Vulcan male and the son of Tuvok and T'Pel.
By 2381, Elieth and his wife Ione Kitain lived on the planet Deneva. During the Borg invasion of that year, the Deneva president gave an order to evacuate the planet before the attackers arrived; Elieth and Ione stayed behind to assist the Deneva Civil Defense Corps. His role had been to maintain order at the launch site and ensure the most vulnerable citizens were given priority. After the last transport left, Ione hopefully considered that they might have been able to leave with it; Elieth responded that there had not been, and they were not a priority for evacuation. As the Borg struck the planet, Ione asked what he would miss most, and Elieth responded that once he no longer existed, he would be unaware of any loss. Ione cried lightly, and said she would miss him, and his emotional facade cracked, so that she knew he loved her as they perished. (ST novels: Destiny, Lost Souls)
