In 30 BBY , Adviser Tashu visited the barren Inner Rim planet of Jakku , which lay at the edge of the Unknown Regions . After landing in Palpatine ' s yacht " Imperialis " , he instructed six droids to begin excavating the Plaintive Hand plateau before returning to his ship . Unknown to Tashu , he was being watched by a local human boy named Galli . Galli sneaked aboard the " Imperialis " but was discovered by Palpatine , who gave the boy a choice between death and fulfilling his destiny . Galli ultimately chose to serve Palpatine and returned to guard the Plaintive Hand excavation site . The excavation site became the Jakku Observatory , which was part of the Emperor ' s network of Observatories around the galaxy . The Jakku Observatory stored a replica of the " Imperialis " , various Sith relics and artifacts , ancient computers which projected a map of the Unknown Regions , and a borehole which led to Jakku ' s core . The Jakku Observatory was central to Palpatine ' s Contingency plan to destroy the Empire should he die prematurely .

By 4 ABY , Tashu had become of the Emperor ' s closest advisers , and as such he was part of the Empire ' s uppermost tiers . He was even considered a friend of his Imperial master , or at least as much as one could be . Although he could not wield the Force , a mystical energy field generated by all living things , Tashu had embraced the cult of the Sith , an ancient and malevolent order whose members sought to gain power over the whole galaxy . The Imperial adviser considered himself a historian of the dark side , an aspect of the Force that focused on fear , anger and aggression .

Adviser Tashu , along with a few other high ranking officials , agreed to meet on Akiva , a backwater planet of the Outer Rim Territories that still fell under Imperial jurisdiction , to discuss the future of the Empire . Tashu felt that the remaining Imperial forces should retreat " beyond the veil of star s , " searching for the source of the dark side . According to the Imperial adviser , that was the only way to rebuild a stronger , better organized Empire that would hide in the shadows , and then strike the New Republic in due course . However , Tashu was at odds with other members of the newly - created Imperial Future Council . The self - proclaimed Grand Moff Valco Pandion wanted to go on the offensive , using the planets still under Imperial control to conscript more soldier s and using their remaining starship s to attack the New Republic and nip it in the bud . The banker Arsin Crassus , for his part , wanted to negotiate with the enemy . During the proceedings , Tashu also took the time to interrogate and torture a New Republic starfighter pilot named Wedge Antilles , who been captured by the convener Admiral Rae Sloane while on a scouting mission .

In 5 ABY , Tashu was visited by the former Imperial loyalty officer Sinjir Rath Velus and his friend Temmin Wexley , who had joined a group of rebels who hunted down Imperial war criminals . After some delays , Sinjir managed to force the guard to open the door to his cage . Tashu recognized Sinjir , who returned the greeting and then asked him about Imperial prison s . After some babbling , Tashu reluctantly told Sinjir to visit the Siniteen prison builder Golas Aram on the planet Irudiru on the edge of Wild Space . Using this information , Sinjir and his team managed to free a hundred prisoners from the automated Ashmead ' s Lock prison on the planet Kashyyyk including Temmin ' s father Brentin Lore Wexley . However , this turned out to be a ruse by Rax to use the prisoner s to attack the New Republic leadership . During the attack , Traducier freed Tashu from prison . After being reassured that Traducier had not come to kill him , Tashu thanked the darkness for saving him . Traducier then directed Tashu towards a ship on Docking Platform E - 22 . When Tashu queried about Shale , Crassus , and Pandion , Traducier revealed that Pandion was long dead and that he had murdered Shale and Crassus . When Tashu inquired why , Traducier replied that he had received orders to kill them and to free Tashu . Traducier clarified that Rax was the new Emperor and that Rax served Palpatine . Tashu praised the late Sidious for having a plan before making his escape . Serving Gallius Rax . In the months following the attack on Chandrila , Yupe Tashu escaped to Jakku , where the self - proclaimed Counselor to the Empire Gallius Rax had brought the Imperial remnants in order to test their mettle . Due to his close connection to the Emperor , Tashu and Rax were among those privy to the Contingency , the late Emperor ' s plan to destroy the Empire in the event of his death . Tashu was present when Rax killed his former master the Anchorite Kolob . Tashu regarded Rax ' s death as an offering to the dark side . Tashu then informed Counselor Rax that he had a visitor in the form of one of the Emperor ' s sentinel droids . The sentinel droid informed Tashu and Rax that Grand Admiral Sloane was traveling with Niima the Hutt ' s convoy to the Jakku Observatory . Tashu was present when Rax ordered the Observatory ' s turbolaser s to bombard the convoy . Master of the Acolytes . Later , Tashu traveled to the Colonies planet of Devaron where a cell of the Acolytes of the Beyond had gathered for an attack on a New Republic outpost near the Karatokai Mountains . This was part of a series of coordinated strikes against New Republic targets throughout the galaxy . Among the Acolytes was a young Pantoran woman named Kiza and her lover Remi . Remi had stolen a Sith lightsaber from the archive beneath the Peace and Security station in the Corellia n city of Coronet City . As the master of this group , he gifted Kiza the mask of Viceroy Exim Panshard at the wishes of the venerable specters of fallen Sith . When Remi tried to seize the mask for himself , Tashu chastised the youth for angering the venerable specters . As punishment , Tashu seized Remi ' s lightsaber and handed it to Kiza .

While the Huxes and the child soldiers boarded a replica of the Emperor ' s luxury yacht " Imperialis " , Tashu and Rax entered the Observatory to initiate the Contingency . After making their way past several computers which the Empire had been using to calculate safe routes through the Unknown Regions , the two men entered a hallway containing artifacts from the old Sith Empire including a red mask , a white lance , a bloody banner , and a black holocron . Tashu donned the Sith artifacts and carried the holocron , which caused him to grow paler from touching it . The two then crossed a walkway which extended over a deep borehole which led to Jakku ' s core . Before Tashu could give a prayer to the Sith , Rax told him that Palpatine would be pleased with them . Tashu responded that they had activated the Contingency and called on them to give a prayer to the darkness . However , Rax interjected and asked Tashu what he would say to the Emperor when they saw their Master again . Before Tashu could give an answer , Rax threw him over the walkway . Tashu hit a rock and was killed on impact . His body then fell down the borehole into the planet ' s core . Since the artifacts contained a great deal of energy , they triggered a chain reaction that caused Jakku ' s mantle to crack . As part of the Contingency , Rax wanted to destroy Jakku and the surrounding Imperial and New Republic forces . He and a select group of Imperials would then travel to the Unknown Regions to restart the Empire . Ultimately , Rax ' s efforts were foiled by Grand Admiral Sloane and the New Republic operatives Norra and Brentin Wexley . Personality and traits .

Yupe Tashu was a wild - eyed religious zealot who refused to abandon his loyalty to the Empire and Darth Sidious . He put the Empire above his own self interest and needs . While Tashu saw himself as a zealot and loyalist , others like the former Imperial loyalty officer Sinjir viewed him as an insane fanatic . Tashu ' s loyalty to Palpatine led him to believe that the void awaited those who betrayed the Emperor . While Tashu was reluctant to accept Rax as the new Emperor , he was mollified when Windom Traducier reassured him that Rax served the late Emperor . As a follower of the dark side , Tashu served as the master of a cell of the Acolytes of the Beyond , a cult that worshiped Sith . Tashu was known to officiate over the sacrifice of sentient beings and to consult with the specters of fallen Sith . He owned a collection of Sith artifacts and masks .
