Ghrath was a Na'kuhl obersturmführer who served under the command of Vosk in the Temporal Cold War.
In an alternate timeline created by multiple temporal incursions by various factions in the Cold War, the Na'kuhl assisted the German Nazis during World War II and conquer the East Coast of the United States. In 1944, the Nazis captured Starfleet Captain Jonathan Archer, who had been transported back to this time period, when their convoy was ambushed, allowing Archer to escape. Ghrath was ordered to search for the missing captain and later suspected Vic, an American resistance fighter, of providing assistance to the ambush. Archer later discovered that Ghrath regularly obtained information about both the resistance and the Gestapo from Joe Prazki. Ghrath was killed by Sal after Archer interrogated him about the Na'kuhl's presence in Earth's past. (ENT: "Storm Front")
