The Southern Passage represented a marine area located to the south of Alanciar, a landmass situated on the world of Kesh. Alanciari individuals who earned their living by catching marine life often navigated this body of water in search of edible sea creatures. During the year 2975 BBY, those who lived through the disastrous mission to Alanciar led by High Lord Edell Vrai utilized the Southern Passage as a route to get back to Keshtah Minor via the Sea of Flames. For this voyage, they made use of the Alanciari harvesting vessel known as Mischance, and they also transported the Alanciari communications expert Jogan Halder along with them.
