Filar - Nitzan The Filar - Nitzan were a polymorphic sentient species indigenous to the Wild Space planet DNX - N1 . They resembled colored fog or smoke , with two eyes in a color opposite that of the main body : green Filar - Nitzan had red eyes , blue Filar - Nitzan had orange eyes , and so on . The species ' gaseous nature made them immune to physical damage , and it allowed them to change shape quickly enough to avoid energy attacks ; they could even diffuse damage from blaster bolts with a difficult - to - learn skill . However , their lack of a rigid form also prevented Filar - Nitzan from easily manipulating solid objects . Commonly considered legends , Filar - Nitzan were nearly unknown in the galaxy beyond their star system . They featured in stories as cloud demons and gas devils , entities reputed to be dangerous killers and frightening apparitions . Few xenobiologist s were aware of the species ' existence ; those who were speculated that some four hundred individuals comprised the species ' entire population . Nevertheless , some Filar - Nitzan integrated into the greater galaxy as infiltrators and spies . Biology and appearance . The Filar - Nitzan were a species of gaseous sentient beings who looked like puffs of smoke with wisps that wafted from a central mass . Two distinct eyes floated within the billows of the main body . The coloration of the central body and eyes varied widely , but in general , the two parts had complementary hues . For instance , Filar - Nitzan with green , blue , or yellow bodies had red , orange , or purple eyes , respectively . Filar - Nitzan could hide their eyes if necessary . Members of other species generally found the smokey beings ' appearance frightening . Filar - Nitzan were capable of shifting into various forms and controlling their relative density . For instance , Filar - Nitzan were able to condense their gaseous bodies as small as 0 . 3 square meters , or as thin as 2 . 1 square meters . The ability allowed them to sift through small openings , such as ventilation shafts . Filar - Nitzan were impervious to melee attacks and other physical damage but vulnerable to energy - based injury . Filar - Nitzan who had been trained in energy diffusion had the ability to dissipate some of the damage caused by energy weapons or fire and lessen its impact . However , when confronted with a fast - moving attack , such as a blaster bolt , a Filar - Nitzan could simply avert gas from the body so that the potentially lethal blast passed through empty space and caused no damage in the first place . The species ' form gave them a serious handicap when trying to interact with solid objects ; only with extreme effort was a Filar - Nitzan able to handle even a small solid object . They were also slow ; an individual wafted about at about half the rate of an average Human at a run . Nevertheless , their slow , steady movement was completely silent , a fact that made Filar - Nitzan extremely stealthy . Their diffuse nature also made them difficult to detect by beings used to dealing only with solid creatures . Filar - Nitzan had both male and female sexes , and they possessed genetic material that made cloning them possible . Society and culture . Filar - Nitzan could express emotions with their eyes . At least one Fllar - Nitzan had a name : this specimen , Vacander , was calm and peaceable by nature . History . The homeworld of the Filar - Nitzan was a largely unexplored planet known as DNX - N1 . The world had been charted by outsiders by the end of the Galactic Civil War , and it became part of the region known as Wild Space . By the time of the Galactic Civil War , xenobiologist s knew of the species and suspected that the Filar - Nitzan did not number more than four hundred individuals . After the transition from the Rebel Alliance to the New Republic , scientists who studied alien life had not changed their estimate . Filar - Nitzan in the galaxy . Filar - Nitzan were exceedingly rare in the galaxy , and most beings had never heard of the species , let alone encountered one of its members . The few who had met a Filar - Nitzan generally found the experience harrowing , and stories from such interactions used terms such as " cloud demons " and " gas devils " to describe the species , terminology that led most non - Filar - Nitzan to dismiss the tales and to consider the gaseous beings pure myth . Similarly , the Filar - Nitzan ' s shape - shifting abilities subjected them to common prejudices that painted polymorphic species as dangerous killers . A few Filar - Nitzan made their way beyond their home system . For instance , the Kaminoans of the planet Kamino kept at least one Filar - Nitzan specimen in captivity at the planet ' s Malio Preserve Units ; they eventually cloned the species after much difficulty . Filar - Nitzan could be found on Keyorin , a lawless world in the Outer Rim Territories . The Filar - Nitzan ' s gaseous nature allowed them to waft through security systems created for solid beings , a fact that made the species ideal infiltrators and spies . Vacander was one such Filar - Nitzan ; during the Galactic Civil War , he was considered a major threat to the Rebel Alliance . Lieutenant Colonel Palpatine Essex Yerac submitted a report on Vacander to the Alliance SecuriDex that detailed Vacander ' s known dealings with the Galactic Empire and its allies . Behind the scenes . The Filar - Nitzan Vacander appears in the sourcebook " Alliance Intelligence Reports " , written by Craig Robert Carey , J . P . Pietrzak , Bill Smith , and Trevor J . Wilson . The book was published by West End Games in 1995 as part of the " " line . Vacander ' s entry includes game statistics to allow gamemasters to create new Filar - Nitzan characters ; the game rules establish the species as fairly clumsy , physically weak , and inept with technology , yet intelligent and perceptive . Filar - Nitzan have a smaller pool of dice from which to assign various scores than that available to most other sentient species . In contrast , the species receives special abilities to allow them to avoid or lesson damage , although these powers are expensive to improve . The book suggests that players of the roleplaying game not be allowed to portray Filar - Nitzan characters . The illustration for the entry was provided by Matt Busch . " Alien Encounters " , a book published by West End Games in 1998 , reprints the game statistics from " Alliance Intelligence Reports " and adds more background information on the species .
