Sord's species was a reptilian race with dark green, scaly skin with a large fin, or crest, running back from the front of their heads at the mid-line of the skull. They possessed tails and clawed feet and were physically strong. (TAS: "The Jihad")
Background information Edit
The voice of Sord was provided by James Doohan.
Unlike the other individuals chosen for the mission, Sord's specialty was never specified.
Author Michael Jan Friedman has agreed with fan speculation that Sord is probably Gnalish (β), a race first featured in his Pocket TNG novel, Reunion, in particular of the relatively smaller Fejjimaera sub-species introduced in Progenitor. 
In the Star Trek: Stargazer novel series, this species is given the name of "Gnalish" and a member of the species, Phigus Simenon, is the chief engineer of the USS Stargazer under Captain Jean-Luc Picard. The Gnalish species also contains a number of sub-species including the "Fejjimeara" and the "Mazzereht."
