Silri Silri was a powerful Nightsister , a dark side witch of Dathomir . She worked for Tyber Zann and his criminal syndicate , the Zann Consortium , in the time following the Battle of Yavin in the hopes of being able to witness and partake in the destruction that Zann intended on causing . In combat , she used dark side powers , such as Drain Life , and also a lightwhip , an exotic variant of the traditional lightsaber . Silri also had a pet rancor , Cuddles , that she could summon during battle . Biography . Imprisonment and rescue . After the Battle of Yavin , Silri and many Nightsisters were taken captive by Imperial Stormtroopers on Dathomir in an attempt by the Imperial Governor to control them . However , his threats to execute the witch prisoners failed to tame the spirits of the Nightsisters , who rebelled . Meanwhile , Tyber Zann managed to procure an unknown Sith artifact , eventually revealed to be a Sith holocron , from Jabba the Hutt . After exhausting many sources of information to find the secrets of the Sith artifact , he learned of the Dark Side witches of Dathomir , and how the Emperor feared them so much that he ' d interdicted their planet with a fleet of Star Destroyers . In a swift covert strike , Tyber Zann and his lieutenant , Urai Fen , exfiltrated Silri from Dathomir , freeing her , and in return , she promised to unlock the holocron . An uneasy alliance . This alliance was only transitory . Even before Zann and Urai Fen rescued her and took her off planet , they began to distrust her . Later , she claimed to have decoded the holocron and that it was merely a star map , showing systems that had been mapped centuries ago . When Zann took a fleet to Carida to sell the artifact to an Imperial connection he was promised by Prince Xizor , the holocron that Silri was attempting to unlock was stolen by the Empire ' s tactical genius Grand Admiral Thrawn , when Bossk , a bounty hunter purportedly working for the Consortium , betrayed his employers . However , this was arranged by the crafty Zann , who ordered his fleet not to fire on Bossk . Silri was angry at this outrage , as the artifact could be of greater value than some star charts . Tyber suspected she knew something she was not telling him and demanded to know what . She revealed that the artifact could lead to somewhere else . Tyber warned her that if she ever lied to and betrayed him , he swore to wipe the Nightsisters and rancors from the face of the galaxy - - with a standing order that would go on even if he died . Later , Zann took Fen and Silri to raid Emperor Palpatine ' s private vault on Coruscant . Zann ' s main goal was to find the pass key to the Emperor ' s files , to access the locations of the credit - filled Imperial vaults . But Silri , contrary to plan , skirted her duty to guard the transport and stole the artifact , fighting off three generations of Dark Trooper models . Intending to run off with it herself , she met up with Zann and Urai and was forced to go along with them . The small group encountered many Royal Guards and finally battled a Dark Jedi . Fortunately , Zann had a ysalamir with him and the Dark Jedi was killed . A Juggernaut was hijacked aiding the quartet in their escape . On the way back from the narrow escape from Coruscant , Silri sensed the deaths of Emperor Palpatine and Darth Vader at the Battle of Endor , and informed Zann about it . Deciding it was time to steal the " Eclipse " , Zann launched a massive assault on Kuat . Silri was present in the boarding party which overtook the " Eclipse " . Soon after the massive battle was over , with Zann ' s forces victorious . The Sith army . As they pilfered the accounts of the Empire , Silri managed to decode the rest of the holocron and then vowed to show Tyber Zann the " true meaning of power " . Silri followed the holocron ' s clues , which led her to an unknown system where the witch discovered what appeared to be the remains of an ancient Sith army , frozen in carbonite . Personality . Silri had a very violent personality , often threatening others with death when something did not go her way . She was often at odds with the Zann Consortium ' s second in command , Urai Fen , and both often threatened to kill the other . She had a slightly better relationship with Tyber Zann himself , although neither of them exactly trusted each other . Powers and abilities . Silri was a powerful Nightsister , often using a lightwhip in battle . She was also capable of calling her rancor companion Cuddles to help her in battle . Unlike other nightsisters , she did not ride a rancor mount , instead she traveled by foot with Cuddles beside her . She could also drain the life from other beings in the area , increasing her own being in the process . Behind the scenes . Silri was voiced by Kari Wahlgren .
