Thi - Sen and his tribe then fought against Cho and his forces in a battle that both sides suffered heavy casualties , Cho himself being fatally wounded in the process . After the battle , Thi - Sen and Chuchi negotiated a peace treaty between Orto Plutonia and Pantora , afterwhich the Talz were left in peace . Biography . Thi - Sen and his tribe led a secretive life on the frozen world of Orto Plutonia . During the Clone Wars , the Galactic Republic and Confederacy of Independent Systems set a considerable amount of troop s to Orto Plutonia . The droid s encountered the Talz and attacked them . Thi - Sen took this as a threat to his people and so in retaliation attacked the droids in their base . A Republic listening outpost got caught in the middle , as the Talz slaughtered the clones in the outpost , leaving both their helmets and the droids ' heads on spear s . Later , Jedi Knight s Obi - Wan Kenobi and Anakin Skywalker , who were both sent in as part of a task force to investigate the massacre , encountered Thi - Sen and his tribe , who explained to them what happened and that the Talz merely want to be left alone . The Jedi then explained that they came in peace and only want to be friends and arranged a meeting between the Talz and the Pantoran s . Before the Jedi left , Thi - Sen gave Obi - Wan a bear hug as a sign of friendship . Thi - Sen ' s Talz came to the meeting in the wreckage of a destroyed Confederate XT Beetle Transport and politely asked the Pantorans to leave his world . However , Chairman Chi Cho didn ' t want to lose ownership of Orto Plutonia and at the meeting called the Talz trespassers and savages , using the protocol droid C - 3PO to communicate with the Talz . Once again , Thi - Sen said he and his people wanted to live in peace , and asked the Pantorans to pull their people off the planet . Cho , refusing to use diplomacy , deliberately provoked and offended the Talz . Thi - Sen stated that there would be war if the Pantorans didn ' t do as he asked , and Cho accepted the challenge . With war officially declared , the Jedi left for the Republic base to request that Senator Riyo Chuchi make contact with the Pantoran Assembly to declare Cho out of order and strip him of power . Thi - Sen rallied his army and led his people against the Pantorans and Republic . Engaging the clone trooper s assigned to protect the Chairman , Thi - Sen ' s forces quickly overwhelmed the Republic troops , mortally wounding Cho and killing several clone troopers . After the Talz cornered the surviving clones , reinforcements of the Republic arrived in LAAT / i gunships . Chuchi , who had been given authority to negotiate with the Talz by the Pantoran Assembly in the interest of peace , arrived and Thi - Sen chose to stop the attack . Chairman Cho , who had been struck in the back by a spear during the battle , appealed to Senator Chuchi to continue to fight the Talz , proclaiming that it was for the " good " of his people , and was shocked to hear that his authority had been overruled by the Pantoran Assembly , he died shortly thereafter . Chuchi along with C - 3PO approached Thi - Sen and told him that it is a greater sacrifice to live for his people then to die for them . The Senator then offered to concede the sovereignty of Plutonia to the Talz and Thi - Sen agreed . The Republic troops left Orto Plutonia and the Talz returned to their village .
