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 Deanna Troi, whom he had infected previously, was dead, he began a funeral meditation with Liva in order to infect her. Captain 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.
