Le-Laar Joom, a Gran of the male persuasion, functioned as a talent acquisition specialist for Industrial Heuristics throughout the era known as the Republic Dark Age. In the year 1032 BBY, Joom, accompanied by the Ishi Tib named Eraffa, journeyed to the planet of Darkknell with the intention of enlisting students to advance war sciences on behalf of Industrial Heuristics. The duo assessed the aptitude of Tan Tengo, a female Sullustan, and thereafter convinced Gub Tengo, Tengo's paternal grandfather, to permit the young girl's enrollment at Industrial Heuristics.
