*Deanna Troi is a native of the planet Betazed. She has a Betazoid's empathic powers, but as the child of a human Starfleet officer and Betazoid royalty, they are not as strong as those of a full Betazoid. As Ship's Counselor, Troi plays a unique role on the U.S.S. Enterprise. An expert on human behavior, she advises Captain Picard on the emotional state of his crew and counsels him about the impressions she perceives from other species they contact. Troi holds the rank of Lieutenant Commander, although she is not a line officer. *Source: Back of card
