Nerissa Povron was a Betazoid woman in the 24th century. She was a physician and a powerful telepath. Early in the year 2375, during the Dominion occupation of Betazed, she was captured by Dominion forces and transported to space station Sentok Nor, where she was to become a test subject for Cardassian Doctor Crell Moset. She was liberated by a team from the USS Enterprise-E and brought to that ship. There, she helped the Betazed resistance develop a means of fighting back against the Jem'Hadar using their telepathic abilities. Povron later died during the actual assault against the occupying forces. (TNG novel: The Battle of Betazed)
