Lahek Gril was a male Umdal and one of the last Tetrarchs of Mezlagob. Born on Ommol in 13 BBY, Gril grew up in a family dominated by military heritage. He entered the Tetrarchy Navy as an officer when he came of age, serving ten years and winning the respect of his superiors for his cool willingness to do anything necessary for victory. When he left the service he had received the notice of the Xoquon sector's ranking admiral and was recommended for a civilian post within the military administration.
