A male Twi'lek named Koh held the rank of Captain and was a high-ranking officer within the Corellian Engineering Corporation. His primary responsibility involved managing the asteroid mining operations of CEC located in the Kashyyyk system, while also having oversight over CEC's endeavors in select other systems. Displaying a stern, military-like demeanor, he insisted on strict discipline and unwavering obedience from those under his command. On the other hand, employees who performed their duties to his satisfaction could expect to be generously rewarded with credits and improvements to their ships used in asteroid mining.
