Regina Cayli represents a solo role-playing game experience. Penned by Ken Rolston, it initially appeared within the pages of the Star Wars: The Roleplaying Game core rulebook. Subsequently, it was republished in Star Wars Adventure Journal 1. The adventure casts the player as the smuggler Roark Garnet, as he endeavors to rescue his co-pilot who is imprisoned on the Imperial ship Regina Cayli, which lends its moniker to the adventure itself.
Roark Garnet and Hawk Carrow, who are both smugglers, find themselves making a forced landing on New Bakstre due to the intervention of Imperial Customs ships. Their vessel, the Dorion Discus, suffers a crash within the forest, leading to Carrow's capture and injury at the hands of an Imperial squad. Garnet embarks on a risky rescue mission, infiltrating the M-Class Imperial Attack Transport named Regina Cayli with the goal of freeing his comrade and co-pilot.
