Despite his youth , Tark refused to be influenced by the spirit while the other members succumbed to Morrhage ' s influence , and , as a result , indulged in their urges and become paranoid . When they realized what was happening , Sidonie Garen formulated a tactical plan to escape , but Tark was trapped after rescuing Eriz Vossan .

When Tark returned , little was left of his original self . While his former friends had emerged as Jedi Masters , Tark found his own mastery in darkness . Taking the name Vivicar , he had learned the secrets of Morrhage ' s Force plague . This dark technique induced madness into those that Lord Vivicar had known and caused them to become puppets of the Sith Lord , including Duras Fain ' s daughter , Laranna . As his influence spread across the members of his former team , a young Jedi Consular emerged to challenge Lord Vivicar . A Padawan of Yuon Par , this young Consular learned an ancient shielding - technique which could free any under Lord Vivicar ' s influence . It was later used to free the Jedi Masters from Lord Vivicar ' s control and made the Consular immune against the plague . The Consular searched the galaxy for affected Jedi Masters and freed them one by one from Lord Vivicar ' s control . After shielding Laranna , the Consular received a holo - call from Vivicar , who taunted that more Masters would become affected by his plague , and that the Consular would die like the last Jedi who wielded the shielding technique , spent from shielding so many . The conflict against Lord Vivicar ended when the Jedi traced Lord Vivicar to his ship in Hutt Space . Here , Yuon ' s former apprentice made a startling discovery : Lord Vivicar was Parkanas Tark controlled by Morrhage ' s spirit . With no choice , the Consular and Morrhage fought in a brutal duel . The Consular took the upper hand and injured Morrhage . However , if Vivicar dies , then all the Jedi that he infected will die . The Jedi Consular immediately redeems Lord Vivicar as Parkanas Tark , expelling the spirit of Morrhage out of his body . Parkanas , now free from Morrhage ' s corruption and returned to the light side , promised to return to Tython , but he wouldn ' t return to the Jedi Order for everything he ' d done . He decided to remain an exile and go find Tython ' s hidden places where he could remain in peace . But before parting ways , Parkanas left a dark promise that the Jedi and Republic would abandon the Consular . After saving Parkanas Tark , the Consular returned to the Jedi High Council and was granted the rank of Jedi Master and the title of Barsen ' thor for the actions against Lord Vivicar .

He was proficient in the usage of a lightsaber and could also use the Force - leap ability . Also during combat he could use an immensely powerful Force - crush that had the potential to kill instantly . Behind the scenes . Vivicar is the final boss in Chapter 1 of the Jedi Consular storyline in Star Wars : The Old Republic MMO . The fate of Vivicar and the Jedi Masters that he corrupted depends on player action .
