Kashyyyk / Legends Kashyyyk ( see pronunciation ) , also known as Wookiee Planet C , Edean , G5 - 623 , and Wookiee World , was a Mid Rim planet . It was the lush , wroshyr tree - filled home world of the Wookiees . It was a member of the Galactic Republic , endured enslavement under the Galactic Empire , and later joined the New Republic . Natural features . Geography . With no axial tilt and a perfectly circular orbit , Kashyyyk experienced one continuous season . It was composed of a molten metallic core , rocky mantle , and a silicate rock crust . The planet had four continents , making up 40 % of the surface , which were mostly covered in lush , wroshyr tree - filled forests , which were several kilometers high . The planet did have a small amount of desert region in the rain - shadow of its small mountain ranges as well as large plains including the Woolwarricca region . A tropical ocean belt contained archipelagos and long coral reefs . In addition , a few sandy beaches could be found along the shores of its oceans . The Kashyyyk coastlines were lined with a brownish - white sand and thick grasses . Kashyyyk ' s highest peak was Korrokrrayyo Mountain . Much of the planet could be compared to a giant swamp — filled with wildlife and covered with wet soil and large amounts of water . The prevalent ecology could be politely described as a " layered deathtrap , " as the dangers presented by local wildlife increased as one descended toward the forest floor . According to Wookiee culture , this vertical environment consisted of seven levels . The bulk of Wookiee civilization was located on the uppermost seventh level , and even the bravest Wookiees rarely ventured below the fourth level . Unlike most , Chewbacca was known to travel below this marking point for most Wookiees . The ground level was known as the Shadowlands and , sometimes , the " notherworld . " Flora . As previously stated , the wroshyr trees were the dominant flora . Wroshyr trees may have actually been one large connected organism , as when limbs of two tree limbs ran into each other , they would fuse together . The Wookiees inferred great symbolism in this . Jolee Bindo theorized that the species of wroshyr tree was in fact alien to the planet and was planted there by the Infinite Empire . This was based on information given by a Rakata computer left near one of their ancient Star Map s . The forests of Kashyyyk were filled with a tremendous variety of plant life , many with some form of consciousness . The Wookiees learned to communicate with these plants and often came to an understanding about their use . One example of this was with the Orga plants , who allowed the Wookiees to harvest their older roots to use in Life Day ceremonies . Most other flora was parasitic to the wroshyr trees , grew in dirt pockets in crevices of the trees , or was carnivorous . Chyntuck was a species of onion - like vegetable used by the Wookiees as food . The Kthysh was a vined plant used by the Wookiees to make bowcaster strings . There were at least two types of large carnivorous plants in the lower levels . These included a carnivorous , spiked vine plant , and the infamous Syren plant , which played a crucial role in the coming of age rituals for various Wookiee tribes . Both of these plants were capable of consuming adolescent Wookiees or fully grown Humans . Fauna . Besides the primary sentient Wookiees , Kashyyyk was home to various species of banthas , a small population of terentateks , and a host of other species . Usually , the deeper into the jungle one went , the more dangerous the animals became . For instance , the tenacious and intelligent wyyyschokk — a giant red - pigmented spiderlike creature — could track prey for over a kilometer and coordinate with other weavers to organize an ambush . Additionally , many of the species that inhabited the deeper parts of the jungle were capable of bio - phosphorescence , since the deeper layers of the forest were in perpetual darkness . History . Tho Yor . Around 36 , 453 BBY , a group of the native Wookiees entered a Tho Yor which visited the planet . This Tho Yor and those which visited other planets traveled to Tython , where the Je ' daii Order , the earliest incarnation of the Jedi Order , was soon founded by the beings brought there by the Tho Yor . The Wookiees eventually moved off of Tython and settled the forest world of Ska Gora . Infinite Empire . At some point after the departure of the Tho Yor , Kashyyyk was taken over by the Rakata n Infinite Empire . Its surface was terraformed by the Rakata for agricultural purposes , but the collapse of their empire left their terraforming machines unattended , resulting in the planet ' s abnormally large foliage . Czerka Corporation and slavery . In 4020 BBY , Kashyyyk was discovered by Czerka Corporation , which renamed the planet first G5 - 623 and then , after a poll of stockholders , Edean . They recognized the Wookiees ' strength and began to enslave them . In 3993 BBY during the Great Hunt , the Jedi Guun Han Saresh died on the planet fighting a terentatek . During the Mandalorian Wars , the Mandalorians considered conquering Kashyyyk , although they eventually decided against it ; their plans for assault included burning down huge sections of forest and glassing entire continents in order to actually create a place to fight . Sometime after the Mandalorian Wars began , self - exiled Jedi Jolee Bindo made his home on the forest floor of Kashyyyk . In 3976 BBY , Zaalbar , a Wookiee who later aided Jedi Revan , had been banished from Kashyyyk and his brother , Chuundar , usurped the position of Chieftain from his father , Freyyr . Chuundar allowed the Czerka to take Wookiees as slaves in exchange for weapons . Freyyr went into self - exile to the Shadowlands of Kashyyyk . Czerka ' s control of " Edean " was disrupted when , in 3956 BBY , the enslaved Wookiee populace , led by Freyyr and Revan , overthrew the local corporate headquarters and drove all outsiders off the planet , save for the " Ebon Hawk " crew . Old Republic . It was presumably some time after this that Kashyyyk decided to join the Galactic Republic . The Wookiees reverse - engineered the hyperdrive from a Trandoshan vessel . They were welcomed into the Republic through dealings with the Corellians , Verpine , and Alderaanians . During the time of the Cold War , a proxy conflict between the Sith Empire and Galactic Republic , one of the oldest wroshyr trees on Kashyyyk — reportedly millennia old — was dying , and eventually someone was sent to examine its rings and learn more about the planet ' s history . In 1 , 003 BBY during the New Sith Wars , the planet was conquered by the Brotherhood of Darkness . Eventually , Kashyyyk was represented in the Galactic Senate , with Senator Yarua being the last Kashyyyk representative prior to the outbreak of the Clone Wars . The Wookiees colonized both of the major moons of Kashyyyk , as well as other worlds in the system such as Alaris Prime . A few years after the Invasion of Naboo , the Wookiee Trade Guild attempted to tax the Trade Federation for goods passed through the Kashyyyk system . An army of B2 super battle droids , led by Count Dooku , arrived at the Wookiee Trade Guild ' s headquarters and disbanded it . Clone Wars . At the start of the Clone Wars , Kashyyyk remained non - aligned . During the Dark Reaper Project of 22 BBY , the Force Harvester found by Count Dooku on Raxus Prime was tested on the neighboring world of Alaris Prime , but all of the Separatists were forced off the moon afterward , ending the immediate Separatist threat to the system . A small attack on Kashyyyk itself occurred some time later , but this too was repelled , and Kashyyyk retained its non - aligned posture eighteen months into the Clone Wars . The decision on what role the planet would play in the conflict was left in the hands of a number of Wookiee Royal Families , acting through a council dominated by King Grakchawwaa . He initially advocated neutrality , engaging in limited negotiations with both the Republic and the Confederacy of Independent Systems , which wished to control hyperspace route planning and to use the Wookiees ' secret trade routes to disrupt Republic trade and communication , giving them the advantage in the war . However , in 21 BBY , General Grievous grew tired of waiting and ordered his local Neimoidian commanders to launch several probe droids to help ' persuade ' Grakchawwaa to make the right decision . He was on the verge of agreeing to join the Confederacy out of self - preservation , when news came that his son , Prince Rikummee , had accidentally been killed by the droids . In anger he allied himself with the Republic , ultimately forcing the Separatists to mount a massive invasion in the closing stages of the war . In 19 BBY , a rescue mission led by Jedi General Etain Tur - Mukan and RC - 1138 , was in the process to rescue Chieftain Tarfful held captive by Trandoshans . The mission was carried out by Commandos of the Delta Squad , who found more separatist collaborationist among the neighboring Trandoshans than they thought , including General Grievous . In response , the Republic dispatched a task force led by Master Yoda and Clone Commander Gree to defend Kashyyyk . At the coastal city of Kachirho , a combined force of clone troopers and Wookiees fought against the Separatist droid invaders , with Yoda himself participating in the battle . Despite the overwhelming Separatist forces , the Republic and the Wookiees emerged victorious from the Battle of Kashyyyk , though taking very heavy casualties . Not long afterward , the secretly married Jedi couple of Kento and Mallie Marek took refuge on Kashyyyk , and the pregnant Mallie gave birth to Galen on Kashyyyk . Galactic Empire and slavery . However , victory was short - lived for the Wookiees . With the rise of the Galactic Empire , the Jedi were branded enemies of the Republic / Empire as Supreme Chancellor Palpatine made himself Emperor and initiated Order 66 . The clone troopers then took control of Kashyyyk , killing Luminara Unduli , sending Quinlan Vos into hiding , and forcing Yoda to kill Gree and discreetly escape from the battle on a Can - cell . Later Yoda escaped the planet , with the help of Tarfful and Chewbacca via a former Republic escape pod . The Empire was quick to suppress Kashyyyk by renaming it " Wookiee Planet C " ( as it was the third orbit in its system ) and placed it under martial law . Several months later , a group of Jedi including Olee Starstone went to Kashyyyk to search for the other Jedi who had been there . The Empire , led by Darth Vader , tracked them and attacked the planet . In response , the Wookiees rebelled against their oppressors , but were ultimately unsuccessful . Clone troopers attempted to land , but many were shot down by abandoned Confederate weaponry utilized by the Wookiees . Darth Vader landed and killed two Jedi before being stopped by Master Roan Shryne , who also died at Vader ' s hand . The orbital fleet bombarded the planet , causing severe damage on the surface . Wookiees either escaped into the undergrowth or into space , where they were stopped by a Detainer CC - 2200 interdictor cruiser . Starstone had slicer Filli Bitters slice into an abandoned CIS ship and crash it into the interdictor cruiser . Many refugees escaped , including Starstone and her Jedi friends , Filli and his smuggling group , and Chewbacca . The Empire occupied the planet , allowing then - Moff Wilhuff Tarkin , one of the Imperial commanders that participated in the battle , to capture and export Wookiees as slave labor to Despayre , in order to help construct the First Death Star . In 18 BBY , Mallie Marek was killed by the remnant of the droids and Trandoshans from the battle a year prior . Almost immediately , her death caused Palpatine to sense Kento ’ s presence on Kashyyyk , thus he sent Vader to eliminate him . Vader and his troops met heavy resistance from the local Wookiee population , but ultimately the 501st Legion succeeded in crushing the uprising . During the battle , Vader bested and killed Kento Marek . Upon discovering his opponent ' s son Galen Marek , whom he found to be extremely powerful in the Force , Vader exterminated all witnesses , including the stormtrooper commander , and went on to train the boy as his secret apprentice . During the occupation , Kashyyyk was opened by the Imperial authorities to slavers from neighboring Trandosha and Mytaranor . At the advice of the Trandoshans , the Empire began using the powerful Wookiees to carry out slave labor . Wookiee captives were used for countless Imperial projects , including the Maw Installation . However , because of their devotion to their homeworld , many Wookiees would evade the Imperial garrison there to revisit their beloved forests for important Wookiee holidays such as Life Day . In 2 BBY , Princess Leia Organa of Alderaan was secretly sent by Emperor Palpatine to be held as a hostage on the planet , in order to keep her adoptive father from speaking out against the Empire . Leia was placed under custody of the local commander , Captain Ozzik Sturn , who used to hunt Wookiees for sport , and confined in her private quarters . Eventually , she was rescued by Galen Marek , himself on a mission by Jedi Master Rahm Kota to track down Bail Organa . Leia promised to reveal the location of her father , but only if Galen was able to destroy a skyhook , which was designed to transfer Wookiees offworld for slave labor . Galen headed to the construction site , slaying Captain Sturn and destroying the skyhook . According to Galen however , " the Empire would just rebuild it . " Grateful for Galen ' s heroic deeds , Leia informed him that Bail had journeyed to Felucia , causing a chain of events that culminated in the signing of the Corellian Treaty . Later , after Marek ' s death at the hands of Emperor Palpatine , Leia Organa met with Bail Organa , Mon Mothma , Garm Bel Iblis , Rahm Kota , Juno Eclipse and PROXY . In which they formed the Rebel Alliance . Leia picked a symbol for the Alliance , the symbol of the Marek family , in a tribute to Galen Marek , his family and his victories against the Empire . One year after the destruction of the first Death Star , Kashyyyk had been subjected to a long orbital blockade . Darth Vader ordered a door - to - door curfew in order to apprehend every Rebel , eventually hoping to get his hands on the crew of the " Millennium Falcon " . However , the Imperials were defeated by Lumpawaroo on Rwookrrorro , and subsequently , the Wookiees , along with the local Alliance members , celebrated Life Day . Moff Hindane Darcc , the Imperial governor of Kashyyyk who ruled the planet from his private palace , forged a pact with the Trandoshan slaver Pekt , appointing him to oversee the entire slaving operation . They had finally installed Avatar Orbital Platform in orbit of the planet , to help further enslavement of the Wookiees . The New Republic . After the Battle of Endor , the Wookiees were freed from slavery by the Alliance of Free Planets . The Nagai then attempted to enslave the species , but they were repulsed by the New Republic . However , the Wookiees ' freedom was short - lived . The Empire , having licked its wounds , quickly reestablished a presence on Kashyyyk and enslaved the Wookiees once more . Around 5 ABY Han Solo and Chewbacca assisted in inciting a revolution among the populace , helped in part by Lando Calrissian , Rogue Squadron , and Admiral Gial Ackbar . Governor Darcc , Pekt and Grand Admiral Peccati Syn were killed during the battle . Kashyyyk was represented in the New Republic Senate by Kerrithrarr , and the planet became a key signatory and member world of the Inner Council . The planet also welcomed trade , and its city of Thikkiiana became a major exporter of computer technology . However , this made it a target of the agents of the Second Imperium in 23 ABY . A task force under Zekk raided Thikkiiana ' s computer stores for use by the Second Imperium in its Post - Galactic Civil War against the New Republic . Galactic Alliance . During the Yuuzhan Vong War , Kashyyyk would be an important member world of the New Republic and , later , the Galactic Alliance . After the Battle of Yuuzhan ' tar at the end of the Yuuzhan Vong occupation , celebrations took place on Kashyyyk . Second Galactic Civil War . It later refused to follow Chief of State Jacen Solo and sheltered the Jedi , who had declared themselves against Solo , so it was attacked by his fleet as a result . Solo ' s flagship , the " Anakin Solo " , began targeting the Kashyyyk forests with its long - range turbolasers , starting a firestorm that would claim the lives of many Wookiees and burn huge amounts of forest . The Confederation redirected fleets from the Battle of Kuat to help the Wookiees , resulting in the eventual defeat of the Galactic Alliance forces , although they managed to escape , due to a tactical blunder by the Confederation Fleet . As a result , Kashyyyk joined the Jedi Coalition , though it did not join the Confederation . Second Imperial Civil War . Darth Krayt ' s Galactic Empire saw danger in Wookiees , but knew better than to enslave the entire species like the previous Galactic Empire did . Instead it cut them off from the rest of the galaxy by having Kashyyyk blockaded and all Wookiee spaceports and shipyards destroyed . No Wookiees were allowed to leave or visit Kashyyyk without an Imperial order and HoloNet transmissions to the planet were completely cut off . Supplies and traders still could come and go , after swearing under penalty of death not to provide Wookiees with information of the state of the rest of the galaxy , but the Wookiees themselves were completely isolated and largely left alone throughout the region . Behind the scenes . The original drafts of " " called for the second Death Star to be built in orbit around Kashyyyk by Wookiee slave labor . It wasn ' t until later drafts that the setting and characters were changed to the forest moon of Endor and Ewoks . The planet was introduced in 1978 in " The Star Wars Holiday Special " and was finally realized on the big screen in 2005 in . Phuket in and Guilin in were the locations scouted for " Revenge of the Sith " , to capture plate photography for Kashyyyk backdrops . In the former , the planet when used as backgrounds was simply reused from the matte painting of Yavin 4 from " " ( as it was known at the time ) , albeit tinted green . In " The Wookiee Storybook " , Attichitcuk tells Lumpawarrump that Wookiees are not Kashyyyk natives , that they immigrated to Kashyyyk from an unspecified planet centuries before . Later sources say that Wookiees are native to Kashyyyk . It ' s possible Attichitcuk was merely spinning an entertaining yarn for his grandson rather than stating something he believed to be factual . When author Timothy Zahn included the Wookiee homeworld in his novel " Heir to the Empire " , he intended to name it " Rwookrrorro , " unaware that it had already been named . Upon learning that it was named Kashyyyk , Zahn suggested " Rwookrrorro " could be the indigenous name for the planet , but this idea was rejected . Zahn used the name instead for a specific city on Kashyyyk . Some believe there is a contradiction between the portrayal of Kashyyyk in the Expanded Universe and its portrayal in " Revenge of the Sith " . While the former ( in pre - " Revenge " works ) portrayed Kashyyyk as a planet with inhabitants living only in trees and never descending to the ground , the latter portrays the planet as having oceans and coasts , with its inhabitants living on the ground . This alleged contradiction could be easily explained in that " Revenge of the Sith " only showed a small part of the planet , and that it doesn ' t necessarily represent the layout of the entire planet . Additionally , " Rebel Dawn " mentions that Kashyyyk has coasts . The PC game " " mistakenly places Kashyyyk in the Sumitra sector of the Outer Rim . Spelling . The 1978 " Star Wars Holiday Special " provides no spelling for the planet ' s name , though its shooting script spells it " Kazzook , " and it is pronounced in the show as that spelling would suggest ( see next section ) . In 1979 , an untitled newspaper comic story arc ( later dubbed " The Kashyyyk Depths " ) that took place on this planet called it both " Kazhyyyk " and " Kazhyyk . " Later that year , " The Wookiee Storybook " spelled the planet " Kashyyyk , " which has been used ever since , with only a couple of exceptions , such as the Super Nintendo " Super Star Wars " games , where Chewbacca is listed to have come from " Kazhyyyk . " Pronunciation . " Kashyyyk " has been many different ways . In its first appearance in " The Star Wars Holiday Special " , it was pronounced / kəˈzuk / . In the video games " " and " " , among others , it is pronounced / ' kæʃɨk / . The G - canon pronunciation , heard in , is / kəˈʃik / . This pronunciation is also heard in " " . " " pronunciation is essentially a combination of the previous two , / kæˈʃik / , but this could be because of the troopers ' accents .
