" While investigating the disappearance of a clone security force , Anakin and Obi - Wan get caught in the middle of an escalating conflict between the furry territorial inhabitants of a desolate ice world and the greedy representatives of a nearby moon . " Plot summary . A force of Republic clone troops under the guidance of Obi - Wan Kenobi , Anakin Skywalker and Captain Rex lands on the iced - up planet of Orto Plutonia to investigate the disappearance of a local clone trooper force . In their company are also C - 3PO and R2 - D2 , along with a party of Pantoran dignitaries which include Senator Riyo Chuchi and Chairman Chi Cho , who uses his political leverage over the Jedi to get what he wants . Despite Orto Plutonia being an ice world apparently devoid of sentient life , Chi Cho vehemently declares that , since it is within the boundaries of the Pantora system , Plutonia is technically considered Pantoran territory . Obi - Wan and Rex check out the local Republic base to find all clone troopers dead , but the facilities untouched . Soon they find a nearby Separatist base , but the droid crew there has also been destroyed , raising suspicion that a third party is behind both killings ; the only clues to their identity are a footprint in the snow and a brief image on a holographically recorded distress call . Back at the Republic base , Riyo Chuchi voices her doubts about Separatists being responsible for the raid , since the evidence is inconsistent with that theory , but Chi Cho stubbornly refuses to give in to such a violent enemy , no matter who it may be . Anakin and Obi - Wan follow their clues to a nearby canyon , where they spot light reflections . Soon afterwards , they do meet primitive but sentient inhabitants , the Talz . Despite the language barrier , Obi - Wan and Anakin manage to make clear that their mission is for peace , and they arrange a meeting between the Pantorans and the Talz . When they deliver the news , Chairman Chi Cho arrogantly refuses to believe that the Talz can be considered a sentient race and calls them trespassers and animals , stating that Pantora hasn ' t found a slight bit of life on the planet in all their history . Riyo Chuchi tries to mediate , telling that it is for the Senate to decide this matter , but to no avail . Upon arrival at the meeting place , the Talz chief tain , Thi - Sen , politely asks that the Galactic Republic leave them in peace and pull off all presence off Orto Plutonia . However , Chi Cho still refuses to accept the Talz as sentients and arrogantly declares Plutonia as sovereign Pantoran property , deliberately provoking a war . In order to gain sanctity for his actions , he declares this to be an internal affair of Pantora . Anakin and Obi - Wan appeal to Riyo Chuchi , to find a way to resolve this political matter diplomatically . She contacts the Speaker of the Pantoran Assembly , who grants her the authority to negotiate peace and declares the Chairman out of order . However , this solution comes a bit too late : while returning to their base , Chi Cho and his escort are ambushed by a Talz war party , forcing them to fight , and Chairman Cho is severely weakened by a spear in his back . Anakin , Obi - Wan and Senator Chuchi just arrive in time to save Cho , Rex and the remaining escort from being overrun , but even with his last breath , Cho insists on killing the Talz for the ' good ' of his people as his final command . Chuchi politely declines , informing him of the Assembly ' s decision . Dumbfounded that he was overruled and that his people prefer peace , claiming that he died for them , Chi expires . Senator Chuchi pursues a peaceful approach and manages to cease hostilities , conceding sovereignty of Plutonia to the Talz . As she and the Jedi board a gunship , Obi - Wan requests that to maintain peace , she should make it last . Behind the scenes . Dave Filoni stated in an interview that the visuals for Orto Plutonia ' s environment were black and white photocopies that George Lucas made of the Badlands , saying that the stark contrasts were what he was looking for in depicting the ice planet . Ralph McQuarrie ' s paintings for Hoth concepts were then applied to the design process for the episode , but without the blue saturation of color . The stylized ice landscapes were patterned after McQuarrie ' s original vision of an ice planet . The snow in the episode is a very much a part of the emotional tone of the story . Joel Aron developed the different densities and types of snow to parallel the moods of the story , including the moment that , when Chuchi " buries the hatchet " with the Talz leader , the blizzard breaks and the snow drifts very gently down . The music that plays at the end is albeit played more soberly and solemnly .
