Plett Plett was a male Ho ' Din from the planet Moltok who served as a Jedi Master during the final decades of the Galactic Republic . A talented botanist and ecologist , he settled on the remote Outer Rim world of Belsavis , in an isolated valley that came to be known as Plett ' s Well . There , he practiced his botanical skills for seventy years , genetically tailoring plants to the unique environment . At the time of the Great Jedi Purge , he provided refuge to dozens of students from the Jedi Temple within his compound . Once Emperor Palpatine discovered the location of the Jedi refugees , he dispatched the " Eye of Palpatine " , a large battlemoon , to raze the enclave . However , the battlemoon was sabotaged by Callista Ming and Geith Eris , two Jedi who had spent time on Belsavis , before it reached the planet . Plett and the Jedi were then able to defeat a small secondary strike force before fleeing Belsavis and scattering . Plett also wiped the memories of the native Mluki , in order to hide all traces of the Jedi ' s presence there . Biography . Jedi Master . Plett was a pale - green Ho ' Din born on Moltok , an Outer Rim world in the Atrivis sector . Eventually growing to a height of 2 . 5 meters , he was trained as a member of the Jedi Order during the final decades of the Galactic Republic , eventually attaining the rank of Jedi Master . Around 88 BBY , he traveled to the little - known planet Belsavis , located in the Ninth Quadrant near the Senex sector , attracted to the planet ' s unique flora . Belsavis was covered by many kilometers of icy glaciers , which were interspersed with rift valleys that were warmed by volcanoes . Plett chose to settle in one of the valleys , partly because the glacial winds and atmospheric conditions limited both access and scanning by visiting spacecraft . He established a small compound with a four - storied tower , inner courtyard , and laboratory , all surrounded by extensive garden s . He also converted a number of caverns into greenhouses for his experiments . Underneath the compound , he developed a crypt accessed through thermal vents . This valley eventually took the name Plett ' s Well , which was later corrupted to Plawal . As was common among his species , Plett was a skilled botanist and ecologist ; he applied these skills in the valley , genetically tailoring many plants to the rift ' s unique conditions of geothermic heat , low light , and microclimates of high acidity . During his years on the planet , he had some interaction with the native Mluki ; years later , those Mluki in the Wutz and Bot - Un rifts passed on legends of his time there . Plett spent some seventy years undisturbed on the planet , watching the rise of Supreme Chancellor Palpatine with dismay , before he was joined by a group of refugees from the Jedi Temple on Coruscant . The group included dozens of children , mostly Humans , although there were also Wookiees , Bith , a Twi ' lek , and an Ithorian among the group . The children were cared for by a few older trainees , such as Margolis Mingla . The refugees converted a number of the Ho ' Din ' s greenhouse caverns into living quarters , making the best they could out of their safe haven ; the direness of their situation was ameliorated by numerous pet pittin s and mandolin music . Plett provided some training for the children , using a number of Jedi toys to stimulate their progress . Plett also took some precautions to protect the children ; he shielded a number of tunnels with mental barriers that induced dread in those that approached , as well as sealing several cupboards with the Force . Unfortunately for the small enclave , their sanctuary was not to last ; Emperor Palpatine discovered their location and commissioned the battlemoon known as the " Eye of Palpatine " to eradicate it . The battlemoon was dispatched to Belsavis eighteen years before the Battle of Yavin ; however , the Jedi Knights Callista Ming and Geith Eris infiltrated the battlemoon en route as it passed through the Moonflower Nebula . When Eris realized that stopping the battlemoon would cost him his life , he opted to try and escape the station and warn Plett . However , he was destroyed while attempting to flee the " Eye " . Ming , who stayed aboard , managed to disable the starship at the cost of her own life , saving Plett ' s life and those of his wards . When the " Eye " never attacked Belsavis , the Emperor ordered a small backup fighter wing of interceptors to attack . Using Y - wings , the Jedi managed to defeat this force . Following this attack , Plett and the Jedi erased the Mluki ' s memories of their time in the valley and fled Belsavis , eventually going their separate ways . Within a year of his escape , Plett passed on the coordinates of Belsavis to three corporations known for their social responsibility and respect for natives : Brathflen Corporation , Galactic Exotics , and Imperial Exports . Galactic Exotics developed shalaman and podon orchids , while Imperial Exports cultivated the cash crops vine - coffee and vine - silk . Together , they domed over the valley , based on a plan prepared by Plett . This investment brought significant economic development to the Mluki . Legacy . Following the Jedi ' s escape , the Empire bombed Plett ' s Well with TIE bombers , reducing the Ho ' Din ' s enclave to broken walls and shattered arches . The Emperor also corrupted some smugglers into crazed dark side beings that he trapped in the tunnels under the valley in order to protect the site from visitors . Of the scattered Jedi refugees that Plett sheltered , the siblings Lagan and Roganda Ismaren were captured by Inquisitor Ameesa Darys . She killed Lagan and subverted Roganda to the dark side . Another of the Jedi children , Nichos Marr , later trained as a Jedi at the Jedi Praxeum on Yavin 4 for a short time before succumbing to the fatal Quannot ' s Syndrome . Among the other survivors of the Jedi children , knowledge of Plett ' s Well was suppressed , although its existence was known of by the House of Organa . Following the death of Emperor Palpatine at the Battle of Endor , Rogana Ismaren returned to Belsavis with her son Irek . There she took shelter in Plett ' s house , training her son with some of Plett ' s toys that had survived the bombardment . Eight years later , Han Solo and Leia Organa Solo visited Belsavis pursuing a rumor of the " Children of the Jedi . " By this time , the Mluki had begun to recover memories of the Jedi presence on the planet . While Solo and Organa were ultimately unable to track down Plett or the younglings , they did foil an attempt by Ismaren to form a military alliance with the powerful Ancient Houses of the Senex sector . They also recovered Plett ' s training tools and Jedi toys that were previously unknown to the New Jedi Order . These were later used to train a new generation of Jedi children . Personality and traits . By the time the Jedi refugees arrived on Belsavis , Plett was advanced in age , his head tresses having faded almost to white . He radiated calm to others and , although worn by struggles over the years , deep strength . He had a strong conscience that compelled him to provide shelter to the Jedi children even at risk to his own life . This also extended to concern for the native Mluki ; after he departed the planet , he arranged for corporations with good reputations to learn of the location of the planet , ensuring economic development for the Mluki while protecting them from unscrupulous exploitation . Plett frequently wore the black cloak of Jedi mastership . Powers and abilities . As a Jedi Master , Plett was proficient in diverse Jedi arts . He was able to effect individuals ' memories , which he did to the entire Mluki village living within Plett ' s Well , causing them to forget the presence of the Jedi within the valley . The effect of this persisted for over twelve years , and was described as preventing those Mluki from thinking about their past . The Jedi Master also created mental barriers using the Force that induced dread in those that approached . This was used to keep the Jedi children out of numerous caverns that contained the dangerous kretch insect . For even greater security , Plett sealed off passages using the Force . According to Mluki legends , the Ho ' Din was also able to speak to birds and other creatures and affect the storms that periodically swept down the valleys . Plett was also skilled as a scientist ; his genetic modifications he made to the plants in his valley thrived even decades after his departure . Behind the scenes . Plett was created by Barbara Hambly for her novel " Children of the Jedi " ( 1995 ) . Written before the release of the prequel movies and their taboo on marriage , the " Children of the Jedi " were originally understood as spouses and children of Jedi Knights . However , " The New Essential Guide to Characters " ( 2002 ) , published after the prequel movies , retcon ned the children into younglings from the Jedi Temple . A second post - prequel source makes oblique reference to Plett : HoloNet News Vol . 531 52 has a story written from Plawal Dome on Belsavis . This is unusual in that the news story was written in 22 BBY when Plett was still on the planet . " Children of the Jedi " indicates that the name " Plett ' s Well " was corrupted to " Plawal " only after the Jedi had wiped the natives ' memories and fled the planet . The " Ultimate Alien Anthology " , which lists Plett as a common Ho ' Din name , depicts a yet - to - be - identified Ho ' Din Jedi . Standing roughly 2 . 5 meters in height , with green skin and garbed in a black cloak , this image is consistent with the description of Plett given in " Children of the Jedi " .
