Sylphe Sylphes were a botanical , humanoid sentient species , native to Sylvia IV . Biology and appearance . Sylphes were a botanical , humanoid species . Their skin was green , and long flowers grew atop their heads . These flowers changed with their emotions , wilting with a bad mood . Their metabolism required high quantities of water , and an extended exposition to an arid climate could be lethal . They communicated with a crystalline language as well as pheromones . These pheromones were used to influence other species ' during negotiations . They also displayed a form of powerful telepathy , which allowed relatives to communicate even at interstellar distance . It was noted to be similar to some Jedi abilities . Though botanical , Sylphes were able to interbreed with Humans , despite having a internal structure closer to vegetation than mammalian . A Human / Sylphe hybrid could be detected by an abnormal blood composition , and had a lifetime superior to a Human , closer to that of a Sylphe . Society and culture . Living in homes made from vegetation , Sylphes were a sophisticated and instructed species . They cultivated refined arts ; their martial arts were no exception . They developed a lethal " war dance " called Sholân Kha . They favored the mental over the technological , and their technological development was quite low . At the time of their first contact with other species , Sylphes were organized into clans , and solidarity was rare . On Sainte - Evanëflore , during the Galactic Civil War , the Sylphes were pacifists and refused to kill anyone if a better solution could be found . History . The Sylphe homeworld was reached by the Galactic Republic between 1189 BBY and 1140 BBY . , before the Golden Age of the Old Republic An exploration team , led by Andrew Woolfson , was sent to the Sylenia V system to search for suitable planets for colonization , discovering four of them . On Sylvia IV , they encountered the Sylphes , and quickly reached a cooperative understanding . The Republic was authorized to install three bases on the planet , and the Sylphes entered into the galactic government , providing a brigade for its military efforts . The Azul brigade was composed of Sylphe and Human soldiers and was known for being one of the elite units of the Republic . The Sylphes remained autonomous , but the Galactic Republic assigned a Governor to them , Karl Descemovitch . In 1125 BBY , the Disaster of Arrakad led to the massacre of the Human population on Sylvia IV and the evacuation of the survivors . In response , the Republic quarantined the planet . During the Galactic Civil War , Sylphes were present on Sainte - Evanëflore and governed by Jonciane , Lord of the Foliage . His daughter was eager to fight the Galactic Empire and did not support the passive , pacifist way of her species . Behind the scenes .

The Sylphes later appeared again in another ambiguously canon roleplaying game help which appeared in June 1996 , the French magazine " Casus Belli 95 " , which was written by Patrick Bousquet and Christophe Debien . The species was illustrated by Thierry Ségur in the later source . Although the authors and publications are different , the data isn ' t mutually exclusive . For this reason , this article assumes that it is the same species .
