Manalin, a planet with a rocky surface, resided within the Joralla system. This system was situated in the Mektrun sector of the Western Reaches, which itself was a region of the Mid Rim. It circled Jaska, a red giant-type sun, in the innermost orbital path. This planet lacked any moons, possessed a poisonous atmosphere, and was incredibly searing-hot, thus rendering it commercially worthless.
The initial mention of Manalin occurred in Planets of the Galaxy, Volume One, a sourcebook published in 1991 for Star Wars: The Roleplaying Game by West End Games. The 2009 book titled The Essential Atlas located the Joralla system, and consequently Manalin, at coordinates L-17 on the galactic grid.
