T'Lar

From Memory Alpha, the free Star Trek reference.

T'Lar was a venerable Vulcan high priestess during the 23rd century.

T'Lar supervised the fal-tor-pan ceremony in which Spock's body and katra (living spirit) were rejoined following his death in 2285. (Star Trek III: The Search for Spock)

T'Lar was played by Dame Judith Anderson.

In the non-canon novel Vulcan's Heart, T'Lar officiates the wedding of Spock and Saavik.
