(Played by Robin Curtis)

Posing as Romulan mercenary T’Paal among Arctus Baran’s small band, and then as a Vulcan V’Shar intelligence agent infiltrating them, Tallera is finally found to be a radical Vulcan isolationist hunting for the Vulcans’ ancient superweapon, a psionic resonator, to further her cause. The covertly placed Captain Picard is barely able to foil her plans and disarm the weapon, which is indeed incredibly deadly and powered by the user's mind.
