Grall, a planet, resided within the Joralla system. This system was situated in the Mektrun sector, which itself was part of the Western Reaches region of the Mid Rim. It circled Jaska, a red giant-type sun, as the second orbital body and lacked any moons. With a temperate climate and a poisonous atmosphere, the planet was deemed to have little commercial value.
The initial mention of Grall occurred in Planets of the Galaxy, Volume One, a 1991 resource for the Star Wars: The Roleplaying Game by West End Games. In 2009, The Essential Atlas, a reference book, located the Joralla system, and consequently Grall, in grid square L-17.
