Death in the Undercity, penned by Michael Nystul, serves as an adventure module for Star Wars: The Roleplaying Game. West End Games released it to the public in June of 1990. Later, it saw republication within Classic Adventures: Volume Three.
The player characters, acting as a team of Rebel agents, embark on a mission to Mon Calamari in this adventure. Their objective is to probe suspected acts of sabotage occurring within the Quarren settlement of Morjanssik. Upon uncovering the actual cause of the alleged "mining accidents," they face the urgent task of averting a potential civil conflict between the Quarren and the Mon Calamari peoples.
Furthermore, the adventure provides pre-generated character sheets suitable for both Quarren and Mon Calamari player characters, alongside a concise "Quarren Fact File" segment that delves into the historical background and cultural aspects of the Quarren species.
