T ' iaz T ' iaz was an alien Dark Side Adept that served Emperor Palpatine . He was killed at Kira Fortress in 11 ABY aiding the Sith Lord in the abduction of Anakin Solo . While there he engaged in a duel with Rayf Ysanna who sliced off his hand and disarmed him . Biography . A member of a humanoid species , T ' iaz was a male Dark Side Adept , serving the Galactic Emperor Palpatine , reborn in a clone body . In 11 ABY , due to treachery by the Emperor ' s physician , who had sabotaged the Emperor ' s clone body before the Emperor had taken it , Palpatine ' s clone body began to decay rapidly . The Emperor ' s other clone bodies had all been destroyed , and he could not clone new bodies of himself , since the physician had also tampered with the genetic material . Palpatine attempted to produce new bodies , using genetic samples from captured Force - sensitive Ysanna shamans from the planet Ossus , but Jedi Master Luke Skywalker foiled that plan . At a loss as how to save his life , Palpatine embarked to the ancient Sith world of Korriban in order to consult the spirits of the ancient Sith Lords buried there . Arriving at the planet aboard his flagship , the " Eclipse II " , Palpatine used a " Lambda " - class shuttle to descend into the Valley of the Dark Lords , accompanied by T ' iaz and another Dark Side Adept . As they traveled through the ancient Sith crypt , T ' iaz felt the dark side power emanating from the place . The Sith spirits told Palpatine that the only way for him to survive would be to transfer his spirit inside Anakin Solo , the newborn son of Princess Leia Organa Solo . T ' iaz swore that he would protect his Master when he would become a child , and would raise him until adulthood . Knowing that Anakin Solo was currently aboard the " Millennium Falcon " , en route to the planet Onderon , the Emperor and the Adepts returned to the " Eclipse II " and traveled to the Onderon system . The massive starship arrived in the system simultaneously with the " Millennium Falcon " . However , the " Falcon " was able to evade pursuit and landed planetside , although it soon left Onderon once again . Sensing that the child was not aboard the " Falcon " anymore , as it was piloted by the co - pilot Chewbacca and the Jedi Vima - Da - Boda , Palpatine chose not to pursue the ship . Instead , he decided to land on the surface of the planet , taking T ' iaz and his physician with him . Posing as an old frail man , the Emperor was able to gain entrance inside Kira Fortress , where Organa Solo was taking refuge with her children . The Emperor incapacitated Organa Solo and the droid C - 3PO . However , a pair of Jedi Knights , Rayf Ysanna and Empatojayos Brand , arrived to join in the fight , having recently arrived with Skywalker on Onderon . Palpatine blasted Brand with Force lightning , removing him from the fight . However , doing so drained his strength . With Ysanna left standing , Palpatine let T ' iaz engage him in battle . However , the darksider was easily overpowered and killed . Having regained his strength , Palpatine killed Ysanna . Skywalker and Han Solo arrived to join the fight , with Solo killing the Emperor with a blaster shot . Palpatine attempted to transfer his essence into the body of Anakin Solo , but his spirit was intercepted by Brand , who dragged him into the Netherworld of the Force . Behind the scenes . The audio dramatization of " Empire ' s End " provides different information regarding T ' iaz ' s death . In the audio drama , instead of going with Palpatine to the surface of Onderon , Tiaz remains to command the " Eclipse II " and dies when the vessel collides with the Galaxy Gun above Byss .
