Liva is the young aide to Ambassador Ves Alkar whom he selects to receive his negative emotions once Deanna Troi appears to have died, in the sixth-season episode Man of the People.
Liva appears in Man of the People. She is a young woman in the party of the Lumerian mediator Ramid Ves Alkar, travelling with him and his attendant Jarth to the peace talks on Rekag-Seronia.
Alkar keeps his composure by pouring his unwanted feelings into a female companion through a telepathic bond, at the cost of her health and life. When Beverly Crusher places Deanna Troi in a state resembling death to break that bond, Alkar wastes no time: he turns to Liva and begins the ceremony that will make her his next receptacle.
The Enterprise crew intervene before the link can be completed, beaming Liva to safety. With no one to take them, the accumulated emotions rebound on Alkar and kill him, and Liva is spared the fate of the women who came before her.
