Er ' stacian Er ' stacians were a sentient species of humanoids with purple skin and three clawed fingers per hand . They lived on Er ' stacia , a planet in Wild Space , where they divided themselves into clans based upon lineages traced back to the tidal pools of their ancestors . The clans revered a single forebear known as the Venerable One , who was represented as a massive stone known as the Megalith . Despite such universal veneration for the object , each clan believed that it should have sole possession of the statue . The situation resulted in near - perpetual clan wars during which the Er ' stacians wielded a mixture of low - and high - tech weaponry , such as swords , spears , and walkers . At some point between 22 and 19 BBY , one such Er ' stacian clan war had grown so out of hand that , when word of it reached the Jedi Council on Coruscant , the Jedi feared it might result in genocide . The council sent Jedi Master Mace Windu to negotiate a peace settlement , but when the Jedi reached Er ' stacia , he found that no peace was possible as long as the clans clung to the belief that only one of them could possess the Megalith . Windu was only able to halt the war by carving up the Megalith into thousands of pieces , forcing the Er ' stacians to either work together to repair it or to divvy up the rubble . Biology and appearance . Er ' stacians were sentient humanoid beings whose hands ended in three plump , clawed fingers . Their mottled , purple hides were covered with knots and spikes . While all members of the species sported round , white eyes ; large , protruding , blocky , bluish teeth ; a red or white tongue ; and a cluster of knobby growths under the chin , clan affiliation determined other phenotypic features . For example , each member of one Er ' stacian clan featured a distinct , upturned nose and a prognathic lower jaw , while each member of another instead sported a prominent snout and a noticeable overbite . Clan affiliation also determined an individual ' s pattern of skin mottling ; one clan featured dark purple spots , while another had circular spots of the same color as that of the rest of the skin . Regardless of their clan affiliation , Er ' stacians cried blue tears , drooled blue saliva , and sniffled blue mucus . Society and culture . Er ' stacian society was divided along clan lines , with each clan claiming descent from various tidal pools pock - marking their homeworld , Er ' stacia . All Er ' stacians were united in their veneration of the Venerable One or Exalted One , the species ' legendary creator and ancestral divider ; worship of the figure constituted the center of Er ' stacian culture . However , the clans disagreed over who should have control of their maker ' s holy megalithic statue , and constant clan wars rocked the Er ' stacians as each clan almost constantly battled the others for possession of the Megalith . Each portion of the statue held religious significance : the single claw held a Pearl of Wisdom , for example , and the sinewy segments brought the Venerable One from the Primordial Pool to conquer the land . All factions agreed that damaging the statue was desecration and blasphemy , and that the mending of damage to the statue took precedence over other considerations . At least some Er ' stacians could speak and understand Basic , although they peppered their speech with " k ' tik " and " k ' tuk " sounds . With rare exception , clan armies fought constant wars on the world for possession of the Megalith , fielding soldiers who wore armor based on their clan affiliation . For example , one clan ' s warriors wore red armor , while another clan ' s wore green and tan armor . The typical suit of armor consisted of a helmet — sometimes with horns — a breastplate , gauntlets , shoulder pads , and spiked knee - high boots , all worn over a simple cloth tunic . Typical weaponry ranged from simple swords , spears , and morningstars to more sophisticated guns and five - legged walkers . Despite their reliance on weapons and armor , Er ' stacian combat experts could also fight with their bare hands if necessary . War banners further differentiated factions in wartime . History . The Er ' stacians hailed from Er ' stacia , a terrestrial planet of hills and tidal pools . According to their cultural legends , the Venerable One was the originator of their species and brought the Er ' stacians to the land when he climbed from the Primordial Pool . Since that time , according to the species ' mythology , their clans could trace their ancestry to various tidal pools . Outsiders from another world made contact with Er ' stacia at some point before 22 BBY , and the world became part of Wild Space . For much of their history , the Er ' stacian clans were at war with one another over possession of the Megalith , a statue representing the Venerable One revered by all clans . Sometime between 22 BBY and 19 BBY , one such war was taking place between two rival clans . Bedecked in their clan armor — red for one side and green and tan for the other — the hostilities escalated . When word reached the outside , the Jedi Council dispatched Jedi Master Mace Windu to the world to avert a potential genocide . Windu traveled to Er ' stacia in his Jedi starfighter to try to put an end to the fighting . The Er ' stacian combatants were in the middle of pitched battle in the vicinity of the Venerable One when Windu arrived . The Jedi Master demonstrated his Force - using prowess and wowed the fighters into a temporary cease - fire , even going so far as to reflect blaster fire directed toward him back on the attacker and then healing him . Windu ordered the two sides to stop fighting , threatening them with his own retribution should they refuse . The Er ' stacians protested that they could not cease their animosity until one side gained sole possession of the sculpture of the Venerable One nearby . Windu proposed slicing the statue in two with his lightsaber , but both sides averred that such an action would be unfair , as each piece of the statue held some religious and cultural significance . During the negotiations , a member of the red - armored clan inadvertently fired a round into the statue and chipped a piece off the Venerable One . The misstep triggered another outbreak of violence , as the Er ' stacian was accused of blasphemy and torn limb from limb . Windu stopped the hostilities once again , and the two clans turned their attention to their holy statue to see whether it needed tending . Realizing that both sides held in common their veneration and protective attitude toward the megalith , Windu sliced it into thousands of pieces . Such desecration brought peace , as both clans worked together to mend the statue or determine which clans would take which pieces of the once - great monument . Meanwhile , Windu departed and reported the events to Jedi Master Yoda on Coruscant . Behind the scenes . The Er ' stacians were created for the story " Puzzle Peace , " first published in 2002 as part of " Star Wars Tales 13 " from Dark Horse Comics . The species was created by writer Scott Beatty and illustrated by Sanford Greene , with inks by Kris Kaufman and colors by Dan Jackson . The story was republished in 2004 as part of " Star Wars Tales Volume 4 " . Although the canon status of stories from " Star Wars Tales " 1 – 19 is ambiguous by default , the Er ' stacian species , their constant quarreling , and Windu ' s mission are mentioned in the " Megalith " entry of " The Complete Star Wars Encyclopedia " , published in 2008 , indicating that the events of the story did indeed take place in " Star Wars " canon .
