Tomed mission

The Tomed mission was conducted by the Vulcan High Command sometime during the first half of the 22nd century.

During the mission, Talok, a Romulan operative in disguise, served under T'Pol. (ENT: "Kir'Shara")

As T'Pol assumed her position at the Vulcan Compound on Earth in 2149, the Tomed mission must have taken place before that.
This mission might possibly have a connection to the Beta Quadrant star Tomed.
