Christophsis Christophsis was a planet located in the Christoph system of the galaxy ' s Outer Rim Territories where the Battle of Christophsis was fought during the Clone Wars . The crystalline planet was invaded by the battle droid armies of the Confederacy of Independent Systems but were repelled by the Jedi and Clone trooper s dispatched by the Galactic Republic . Later , the planet was the site of a second battle between the Republic and the Separatists . After the transformation of the Galactic Republic into the Galactic Empire , the planet was placed under Imperial control , but nevertheless hosted rebellious elements . Description . Christophsis ' s surface was covered in large crystal line forest s and had an atmosphere that was breathable for most humanoid species . The planet was orbit ed by a moon , Leesis . History . The Clone Wars . During the Clone Wars , the Alderaanian Senator Bail Organa visited Christophsis to undertake relief work . However , he and his relief mission was trapped by a Separatist fleet led by Admiral Trench . A Republic fleet led by Jedi General s Anakin Skywalker and Obi - Wan Kenobi , and Admiral Wullf Yularen clashed with Trench ' s fleet and managed to defeat it following a lengthy battle . This enabled the Galactic Republic to deliver vital supplies to Organa and his men . The Republic then established a military base on Christophsis and began a campaign to retake the planet from Separatist forces under General Whorm Loathsom and Count Dooku ' s Sith assassin Asajj Ventress . During the fighting , General s Kenobi and Skywalker hatched a plan to trap Separatist droid forces advancing from two towers . However , their plan failed due to the presence of a traitor within the ranks of the clone trooper forces : Clone Sergeant Slick . Working together , the clone officer s Cody and Rex managed to capture Slick . Meanwhile , Kenobi and Skywalker narrowly escaped a trap at the Separatist base set by Ventress . Despite capturing Slick , the rogue clone trooper had managed to damage several of the Republic ' s weapons . The Republic forces ' problems were further complicated by the advance of Loathsom ' s Retail Caucus droid forces . Despite being outgunned and outnumbered , the Jedi and Republic were relieved by a young Padawan named Ahsoka Tano , who had been sent by Jedi Master Yoda to be Skywalker ' s apprentice . Working together , Skywalker and Tano managed to infiltrate the Separatist lines and shut down their deflector shield generator while Kenobi stalled the Separatist forces by " negotiating " with Loathsom . This tactic paid off and the Republic succeeded in turning the tables on the Separatist forces and capturing Loathsom . Newsreels at Kamino ' s military complex carried reports of the Christophsis campaign . About two years after the Christophsis campaign , the Confederacy still maintained a military base on the planet that was largely manned by b1 battle droid s . After fleeing the Republic " Venator " - class Star Destroyer " Vigilance " , the Separatist leader Count Dooku , the turncoat Jedi Master Quinlan Vos , and Ventress crash - landed on Christophsis ' surface . By this stage , Ventress had been cast out by Dooku and had struck an alliance with the Jedi in return for helping Vos to kill Dooku . Dooku and Vos were subsequently pursued by a Republic landing force led by Kenobi and Skywalker . Unknown to everyone , Vos secretly planned to get Dooku to lead him to his master Darth Sidious so that he could destroy the Sith once and for all . After trudging through Christophsis ' crystalline landscape , the three travelers reached the Separatist military base . There , Dooku contacted his master Darth Sidious to secure safe passage from Christophsis . Shortly later , the Republic bombarded the Separatist base . In the midst of the bombardment , Dooku attempted to kill Vos with Force lightning but hit Ventress instead . Ventress ' death brought Vos back to the light side and he refused to strike down Dooku ; realizing that it would only lead him to the dark side . Dooku managed to escape offworld with the help of Sidious while Kenobi and Skywalker took a penitent Vos into custody . Imperial era . Following the transformation of the Galactic Republic into the Galactic Empire , a rebel cell known as the Spectres raided an Imperial convoy en route to Christophsis in space . This was the second in a string of raids that had snared an Imperial convoy to Ryloth . The rebels then went to raid convoys near Kashyyyk and Toydaria before settling down on the Outer Rim world of Lothal . The Empire also stole the kyber crystal s that were holy to the natives and used the kyber crystal s for the Death Star . Rebellious elements traced by the Galactic Empire to the planet Christophsis were found to be responsible for the theft of one of the Empire ' s medical frigates . The Empire conducted a series of arrests , executed the planet ' s prime minister for Treason and " pacified " the city of Tophen as an example to the populace , in the hope of quelling radical elements . Around the time of the Battle of Jakku , five pilgrim s from the Church of the Force — the MA - B0 cargo lifter droid Mabo , Addar the human , Jumon the Iakaru , Madrammagath the Elomin , and Uggorda the Duros — undertook a mission to Christophsis to return several stolen kyber crystals . They had been dispatched by the pastor and philanthropist Brin Izisca . Over a thirteen day period , the pilgrims navigated through Christophsis ' dangerous terrain . Maddrammagath , Uggorda , and Jumon were killed by several fearsome Force - sensitive creatures called Kyaddak . Despite the deaths of their companions , Mabo and Addar manged to return the crystals to a broken crystal wall . Mabo was destroyed when he fell down a hole while Addar was left to fend off a pack of pursuing Kyaddak .
