The Lenguin system was a star system located on the border between the Mid Rim and the Outer Rim Territories. Within this system existed a gas giant, which was orbited by its ice moon, Madurs. During 4 ABY, Princess Leia Organa and Han Solo spent their honeymoon on the star cruiser Halcyon. Their intention was for the ship to journey to the Lenguin system to engage in discussions with Dreand Yens, the prime minister of Madurs. They sought to convince him to align with the New Republic, aiming to utilize Madurs as a fuel supply. Although the captain of the vessel, Oswin Dicto, initially resisted altering their course to Synjax, he ultimately conceded following the persuasive efforts of both Solo and Organa, leading them to set a course for the system.
