Naarg
Naarg was a Tellarite, who in November 2154 served as an assistant to Ambassador Gral at a conference at the planetoid Babel.
While being transported to Babel on the Enterprise NX-01, an Andorian force led by Shran broke into the quarters of the Tellarite delegation in an attempt to extract information from Gral relating to the destruction of the Kumari. Though the situation was defused by Captain Jonathan Archer and a MACO squad, Naarg nevertheless grabbed a phase pistol and shot Talas, Commander Shran's lover.
Talas eventually died of the phase pistol shot, causing Shran to challenge Naarg to the Ushaan, a duel to the death. Fortunately for Naarg, Captain Archer invoked the right of substitution and dueled in his place. (ENT: "Babel One", "United")
