[Source] The Allyuen system was a star system located within the Anoat sector in the Greater Javin of the Outer Rim Territories region of the galaxy. It contained the planet Allyuen. Allyuen was one of the possible sites the Galactic Empire suspected the Alliance to Restore the Republic might have been hiding following the Battle of Yavin. The Imperial II-class Star Destroyer Stalker, attached to Darth Vader's Death Squadron, dispatched a Viper probe droid to Allyuen in 3 ABY in search of the hidden Rebel base.
