Yekda was a Vulcan in the early 22nd century, and an agent of V'Shar. In 2155, Yekda was a member of a team of V'Shar agents led by Denak to Trilan, to pursue a race of mutated Vulcans called Fri'slen plaguing the outpost there. Yekda was one of three casualties, along with Eskren and Vekk'r. (ENT novel: Kobayashi Maru)
