Plee Plee was a male Ho ' Din plant development specialist whom the New Republic Senate Select Committee for Refugees assigned to a team working on terraforming the surface of Duro in 26 ABY . The planet was chosen to be a refuge for the millions of refugees fleeing the advance of the Yuuzhan Vong — an extra - galactic species intent on conquering the galaxy — and Plee worked on developing plants suitable for reviving the planet . Disputes over priorities and a lack of resources made their task difficult . Plee and the team ' s mission was ultimately unfilled , as the Yuuzhan Vong captured the planet . Biography . Plee was a male Ho ' Din , a reptilian sentient species native to Moltok , located in the Atrivis sector of the Outer Rim Territories . Trained as a plant development specialist , the pale - green Ho ' Din gained a doctorate in his field of expertise . In 25 ABY , the Yuuzhan Vong , a tattooed and an aggressive species from another galaxy , invaded the New Republic . With numerous early successes , they caused a massive flow of refugees to other worlds of the Republic . To deal with this problem , the Republic formed the Senate Select Committee for Refugees , commonly referred to as SELCORE . By 26 ABY , Plee was one of a number of research scientists working for SELCORE , assigned to work on terraforming the planet Duro , under the management of former Chief of State Leia Organa Solo . The Select Committee , under pressure to a find refuge for the multitude of refugees fleeing the Yuuzhan Vong advance , had selected Duro , a long polluted world , as a resettlement location ; however , with Duro ' s atmosphere polluted by dangerous gases , the refugees were forced to live under a series of SELCORE habitation domes . Plee , along with the Talz Aj Koenes and a number of other specialists , was tasked with restoring the planet to a habitable state . Plee developed a number of vegetative species for the planet , at one point petitioning for use of Sector Four of some reclaimed marshlands in which to apply his work . However , the scientists struggled to form a unified plan , competing amongst themselves for scarce resources and the priority of their own projects ; indeed , another scientist tried to claim Sector Four to use for grain projects . In addition to his own work , Dr . Plee was particularly concerned with restoring the atmosphere of Duro , so that the residents could move out from the protective domes . He was also dismissive of concerns over ecological over - breeding , considering it a minimal problem given the vast barren planet . While the scientists made significant progress on making the surface habitable , the efforts of Plee and the rest to create a refugee sanctuary were ultimately in vain , as the Yuuzhan Vong captured the planet later that year , scattering the Republic citizens gathered there . The Yuuzhan Vong later worked on terraforming Duro , eventually restoring it to its lush natural state . Personality and traits . Plee was a scientist , gaining a doctorate in his field of plant development . Although he disputed it , Plee found living under the environmental domes claustrophobic . He wore a lab coat , even to meetings . Plee had green skin . Behind the scenes . Plee was created by Kathy Tyers for " " ( 2000 ) , the sixth novel in " " series . He was later given a short one - line entry in " The Complete Star Wars Encyclopedia " ( 2008 ) .
