Deanna Troi

Deanna Troi was a half-Betazoid, half-Human Starfleet Officer.  She served on the USS Enterprise D and E and during her latter career Troi transferred to the USS Titan.  As a half-Betazoid, Troi was capable of extra-sensory empathy but could not read the minds of aliens with brain structures different from Humans and other Betazoids.  She was very helpful on the Enterprise with mental health issues of the crew.  She often was very valuable when negotiating with other hostile races.  She could tell if others were lying to her and helped the Enterprise Senior Officers in many stressful and suspenseful situations.

Troi was born on March 29, 2336, near Lake El’nar on the planet Batazed to Ambassador Lwaxana Troi and Starfleet Officer Ian Andrew Troi.  Troi had a sister named Kestra who died when Troi was a very young child. 

Troi entered into Starfleet Academy in 2355 and graduated in 2359, majoring in psychology.  She had the rank of Lieutenant Commander and was the Councillor for the Enterprise for many years.  Troi could sense emotion and fear in other ships whether they were enemies or allies.  Also, when the crew of the Enterprise was away on missions, she could sense if they were doing well and report to the captain if the communicators were not functioning.  Her senses were much more advanced than the technology of Starfleet communicators even if the communication was non verbal.

Deanna Troi married William T. Riker during the latter part of her Starfleet career.  Troi and Riker knew each other for many years.  They first met on her home planet when Riker was stationed there as a Lieutenant.  Lieutenant Riker wanted to pursue his career so Troi followed him to the Enterprise when Riker became a Commander.
