Si'tann

Si'tann was a male Vulcan who lived by the 24th century and was a noted Vulcan master.

A holographic program of Si'tann was used by Ensign Sovak in order to teach him the Vulcan discipline of the Vulcan nerve pinch. By 2376, the hologram of Si'tann continued to serve as his patron and Sovak proved himself as a successful pupil by succeeding in the technique. Master Si'tann congratulated Sovak on completing his Vulcan training and honoring the memory of his biological parents.

Following the completion of the Xenophore Seed mission, Sovak consulted the holodeck program once more of his master and wondered on his fate as he desired to remain assigned on the USS Enterprise. When the ensign received a summons from Captain Jean-Luc Picard, the hologram of Si'tann determined that logic stated that a destiny was forged by the individuals own actions. Thus, he suspected that his pupil's fate had changed and Si'tann was proven correct when Sovak was invited to a card game by Captain Picard.
