Nelan Decker

Lieutenant commander Nelan Decker was a Betazoid/Human hybrid female who served as the counselor on board the USS Valentine. Like her friend Deanna Troi, she was part human. Her mother was Dewin Decker who like Troi's mother, Lwaxana Troi was a silly person. (Star Trek: The New Adventures, TNG: "Safe Heaven")

She was played by Paula Hughes.

There is plans to make her a supporting character like Deanna Troi but has not been confirmed by Ronald G. Hutson.

Her rank and division in Starfleet is confirmed in the script.
