During Kyle Katarn's first mission to Nar Shaddaa, Katarn had to locate an Imperialnava card describing the activities of all the smugglers involved in the Dark Trooper project. Unfortunately, by that time, Mohc had put a bounty on Katarn's head, and several bounty hunters and smugglers set out to capture or kill him. This resulted in a skirmish in the streets and several shootouts between Katarn and them, in which Katarn resulted victorious.
"So this is Katarn, the one who has been a thorn in Mohc's side."

Katarn did locate the navigational charts, but upon leaving the moon he and Ors were captured by Jabba the Hutt and placed into custody in the Star Jewel. Jabba kept several Kell dragons on board his starship and would feed prisoners to them for entertainment. Kyle managed to slay the Kell dragon he was pitted against, and upon retrieving his weapons and escaping the dragon den he proceeded to exterminate Jabba's entire complement of the beasts. He was able to regain the card, rescue Jan Ors, and reach the Moldy Crow with which they escaped.
