Da Soocha V Da Soocha V , also known as the Pinnacle Moon , was the fifth moon of Da Soocha in the uncharted Cyax system , located within Hutt Space . Geography . Da Soocha V was largely covered by kilometer - high jagged , stone spires created by ancient volcanic eruptions and was thus nicknamed " Pinnacle Moon " by the New Republic . The moon ' s sole native sentient species were the small winged Ixll s . Da Soocha V was also home to the predatory tumnors which preyed on the smaller Ixlls . History . During the Galactic Civil War , the obscure Cyax system was scouted by Rebel Alliance scouts who discovered the ocean world of Da Soocha sometime around the Battle of Endor . In 10 ABY , after the Invasion of Coruscant and subsequent Imperial Civil War forced the New Republic to abandon Coruscant , they established a command base on Da Soocha V due to its relative obscurity . The primitive Ixll natives were fascinated by the arrival of the New Republic staff , particularly because their starships frightened away the large winged predatory tumnors which had previously preyed on young Ixlls . To establish the base , New Republic engineers cleared and expanded the caverns within the immense stone spires to accommodate hangars and operation decks for the vessels of the New Republic Navy . After Jedi Master Luke Skywalker was captured and brought under the influence of the Reborn Emperor Palpatine , the Emperor arrived above the moon in his " Eclipse " - class dreadnought " Eclipse " accompanied by a small flotilla of vessels . Palpatine ' s fleet caught the weary New Republic defenders off - balance and the Emperor was able to make his demands unchallenged . He demanded that Leia Organa surrender to him and board his vessel , something she did willingly , as he still held her brother , Luke Skywalker , under his influence . Attempting to break Organa and bring her unborn child under his influence , Palpatine goaded Skywalker into attacking her and prove himself still worthy of following the way of the dark side . Reaching out to his lingering good side , Leia managed to bring Luke out of his mental captivity and the Jedi Knight attacked his former master , only to provoke the Emperor into unleashing a Force storm that began to devour the Republic ' s fleet . Using the Force to counterattack , Luke and Leia weakened Palpatine ' s power , sending the storm out of control and causing it to devour " Eclipse " . The Skywalker siblings made it out of the ship as it tore apart in a shuttle . At the time , it was believed that the Emperor was destroyed aboard his capital ship . Following the New Republic attack on Palpatine ' s citadel on Byss and the escape of the surviving Rebels into hyperspace along with a group of smugglers , Palpatine gave the order for the Galaxy Gun to launch its first world - destroying projectile against the New Republic command on Pinnacle Moon . However , due to the presence of spies on Byss itself , the New Republic forces along with some of the native Ixll s managed to escape the doomed moon in a fleet of transports . Despite efforts by Luke Skywalker to destroy the missile using the weapons systems onboard his transport " Jedi Explorer " , the projectile collided with the crust of Da Soocha V and unleashed a nucleonic chain reaction which wiped out the moon in a single flash and effectively wiping it off the face of the galaxy . Behind the scenes . In " Dark Empire II " , the moon is erroneously referred to as Gla Soocha V . However , the PC game " " offers " Gla Soocha " as a common alternative for the planet Da Soocha , suggesting " Gla Soocha V " may be a similarly used alternative .
