T'Lyn

T'Lyn was a female Vulcan who lived during the 24th century. She served in the Vulcan High Command aboard the Vulcan cruiser Sh'vhal until 2381, when she was transferred to Starfleet and assigned to the USS Cerritos.

Her transfer was a result of conflict with her compatriots over her, by Vulcan standards, defiant willingness to allow her logical reasoning to be influenced by additional factors, such as intuition.
