Esh - kha The Esh - kha were an alien species that inhabited the galaxy before being imprisoned on the planet Belsavis thousands of years ago . Biology and appearance . In terms of appearance , the Esh - kha were a gray - skinned humanoid species with equine features , including muzzles and digitigrade legs . They also had small black eyes . Society and culture . In terms of society , their race ' s culture resembled that of a hive society though each individual retained their own thoughts and aspirations yet all being bred for a specific role that they were eager to fulfill . A caste system was present amongst the Esh - kha which included Force - sensitive simple minded savants , more numerous skilled determined warriors that watched over them and finally the patriarchs that acted as leaders who provided their wisdom as well as decisions to their entire people . Whilst their kind were individuals , Esh - kha were not named at birth but instead earned their names through their actions . Thus , those members of their kind that displayed cunning were able to be called " " Razor Mind " " , " " Water Thinker " " or a similar such naming convention . An Esh - kha that displayed great skill in battle could be called " " Swift Blade " " , or maybe " " Deadly Cutter " " or some other such name . It was believed that this partly explained an Esh - kha ' s zeal in battle with young warriors seeking not only victory but an opportunity to lay claim to a name and forge their own identity . Esh - kha appeared to outsiders as a savage violent species that cared only for the destruction of all other races . This hatred for other sentient species was believed to had stemmed from their tightly - knit hive - like society . It was suspected that the Esh - kha were simply unable to tolerate or even adapt to the existence of thinking of outsiders who only suffered their wrath . Their race only turned violent against one another in the most extreme of circumstances .

Only the ancient warnings carved on the prison walls of Belsavis provided an in - depth history on the Esh - kha race . According to these writings , this race were once considered one of the most feared species in the galaxy during its distant past . They were known to have arisen from their isolated homeworld , whereupon they began to cut a swath of destruction across countless systems . These campaigns saw entire races being hunted to extinction by the savage Esh - kha , who expanded into their conquered worlds . The population of the Esh - kha expanded as their living space increased and this led to the rise of a new rival patriarch , even as the old one was still alive . Such an event was unmarked by this species and this new patriarch known as Hallow Voice proposed a more peaceful approach in their dealings with other races through cooperation . As the Esh - kha population grew too large , Hallow Voice took a number of his followers away who settled on other worlds in order to reach out to other nearby cultures . During the height of their race , they were known to have conquered half the galaxy . Despite their works , the Esh - kha became well known for violence and mass destruction with only a few tentative alliances being formed . During this time , the marauding Esh - kha destroyed dozens of slave worlds that belonged to the Infinite Empire . These incursions eventually attracted the attention of the fearsome Rakata , who assembled a massive military force against this threat . Their conflict was known to have engulfed the entire galaxy which nearly saw the Esh - kha wiped out . Ultimately , the Infinite Empire won the resultant conflict and took the defeated hundred thousand surviving Esh - kha to the prison world of Belsavis . Once there , they were imprisoned within the Tomb in stasis beneath the surface , where they were kept in a conscious state , though immobile The Esh - kha were left in the darkness for thousands of years . A monument of this achievement was placed on Hoth , where an interactive hologram detailed the punishment of the Esh - kha and that their imprisonment was meant for them to reflect on their mistake in challenging the Infinite Empire . Scattered mentions of this imprisoned army were present in numerous texts that were later available to the Noetikon s . In later years , Jedi historian s came to wonder on whether the legend of gray - skinned warriors in the Outer Rim did not refer to the Taung , but may have been sightings of Hallow Voice ' s followers . By the Cold War era , the security systems of Belsavis began to break down leading to the Esh - kha being freed from stasis . Once freed , they began to resume their campaign of ruthless expansion and zealous combat . Among their noted goals appeared to be releasing their kin that remain trapped on Belsavis and spreading as much chaos within the prison planet as possible . As time moved on , they continued to recover more technology and strange weapons as they attempted to return back to the stars . Freed Esh - kha also began pillaging nearby vaults for weapons , such as plasma dischargers , for use against their enemies while others worked as saboteurs who began disabling the stasis field generators in order to free more of their kind . Following their release from the Ancient Prison Caverns by the Sith , the Esh - kha attacked both Imperial and Republic forces equally where they devastated their lines . An Imperial individual was tasked with preventing the Esh - kha from salvaging Rakatan stasis technology for their own uses . A Republic Individual was also dispatched to prevent Esh - kha from salvaging a crashed starship on Belsavis as a means of escaping the prison world . The Barsen ' thor of the Jedi Order sought out the Esh - kha as a possible army for use against the Sith and was aided in freeing Hallow Voice by the Rakata Lhunu . Among the noted patriarchs that controlled the freed Esh - kha included Gore Claw who intended to free an ancient entity known as the World Razer that was trapped deep within Belsavis . In addition , they sought to take control of the Rakatan transportation technology as a means of escaping Belsavis . A group of Esh - kha also attempted to harness the great power of the Dread Masters until they were freed . Darth Synar was noted to have held an interest in the Esh - kha and sent her servants to acquire some of their High Savants that were talented in the Force . However , her followers failed and she tasked a Sith spacer with capturing the specimens with a subjugation device .
