T'Hain

From Memory Alpha, the free Star Trek reference

T'Hain was a Vulcan writer. The Dictates of Poetics is one of T'Hain's works.

In it, T'Hain says:

"A character's actions must flow inexorably from his or her established traits."

Tuvok had quoted T'Hain when a holonovel malfunctioned in 2373. (VOY: "Worst Case Scenario")

Although the "T'" prefix suggests a female name by traditional Vulcan naming patterns, we do not know if T'Hain is male or female.
