Liva

From Memory Alpha, the free Star Trek reference

Liva was an aide to Ves Alkar, a Federation Mediator.

Liva assisted Ves Alkar during the mediations in the Rekag system. Ves Alkar used women to transfer his dark and hateful emotions into their brains, in order to make his mind pure for his negotiations. This process caused premature aging and death.

Liva almost became one of his victims. Believing Troi, whom he had infected previously, was dead, he began a funeral service with Liva in order to infect her. Jean-Luc Picard, aware of his intentions, beamed Liva away, leaving Alkar alone. He was flooded with his evil thoughts that he normally transferred to others, and he died. (TNG: "Man of the People")

Liva was played by Stephanie Erb.
