Kharl Vanneb, who originated from Naboo, completed his studies with honors at the Theed School of Technology and Engineering during his younger years. Following this, he was assigned to Ohma-D'un to work as a Third Grade Assistant Technician.
Vanneb possessed a sociable and communicative demeanor, finding pleasure in conversations about starship engines and the upkeep of life support systems. Kharl maintained a longstanding friendship with Sakme Kelene, who also graduated from the Theed School of Technology and Engineering; both individuals had jointly applied for employment at the Gungan lunar installation situated on Ohma-D'un.
While en route to the moon base on Ohma-D'un aboard the Fair Gale, piloted by Captain Worlohp, Kharl and Sakme, accompanied by Professor Hallem Celaar, experienced an incident. A collision with debris from a Trade Federation ship resulted in an unforeseen Kyvalon-4 breach, instigating chaos on the vessel and leading to the captain's incapacitation by a coalition of passengers.
