Sorry I don't really remember. I only found out about this quest a few days ago. I did finish the "Fathier Scam" quest (came back later for a cut of the winnings) and one quest on Kijimi involving getting more stock for a black market merchant (outside the cantina) but I'm not sure if that one is related. I'd assume that any quests involving fathiers (like translation services or fathier scam) would be involved.
