Crymsin Ost was a Force - sensitive Human female who served the Jedi Order during the waning years of the Galactic Republic , and she trained as Jedi Guardian , a combat - oriented Jedi specialization . At some point Ost lost her sanity and fell to the dark side of the Force ; she abandoned the Jedi and affiliated herself with the Believers , a Sith cult that was based in the Cularin system . She eventually became an important member of the cult and , with help from the Ithorian Believer Force Adept Disch ' l , constructed a pink - colored lightsaber for herself . In about 21 BBY , during the Clone Wars , the Believers embarked upon a plot to wipe out most of the Caarite s — a sentient species that operated the Metatheran Cartel trade organization — by dispersing a deadly virus on the Caarite homeworld , Caarimon . Ost was placed in command of the operation , and she journeyed to Caarimon aboard a transport that had collected large quantities of the virus from a secret Believers laboratory on the planet Genarius . On arrival in the Caarimoos system , Ost ' s transport docked with the research station Creautaa - V in orbit of Caarimon , and she disembarked from the vessel along with the rest of her strike team : Disch ' l , the Believer Eph , and Melo Centris , a renowned assassin who had been hired to assist the Believers with their mission . The Believers released a sample of the infection and wiped out all of the installation ' s Caarite crew , then off - loaded a tank of the virus and ferried it to the lowest level of the station . There , they filled some escape pods with the virus and prepared them for launch in the direction of the planet , and they also rigged the pods with explosives , hoping to crash them into fault lines in the Desolation region of the world and cause a major cataclysm . Meanwhile , another group of Believers landed on Caarimon and rigged a homing beacon in the Desolation region , and Ost and her crew waited to receive a signal from the transmitter . A group of freelance agents from the Cularin system known as the " Heroes of Cularin " traveled to Caarimon to investigate the Believer plot , and , after disabling the homing beacon in the Desolation , they boarded the Creautaa - V and confronted Ost ' s strike team . Ost ignited her lightsaber and moved to attack the operatives , while Disch ' l used the Force to create an illusory version of the fallen Jedi , as a distraction . Despite their efforts , Ost and the other Believers were eventually defeated , and the agents prevented the virus from being dispersed on the planet . Personality and traits . Crymsin Ost was insane and devoted to the ideals of the Believers , and she was willing to commit genocide in order to further the cult ' s aims . Like all Believers , she had a tattoo on the front of her right shoulder that depicted the Sith Fortress on the planet Almas , with a lightsaber handle snapped in two , which formed the base of the fortress ' s spire . However , Ost ' s tattoos were modified such that if she clicked her teeth in a particular pattern , a fatal dose of poison would spout from sub - dermal implants beneath the tattooed lightsaber handle , giving each halve a red - colored blade . Powers and abilities . Ost was used to going into battles with an illusory version of herself beside her , such as the apparition created by Disch ' l during her fight against the Heroes of Cularin . She knew how to use the Force to sense things , to move objects , to heal herself , to improve her combat abilities , and to drain energy . In addition , she was familiar with the powers Battlemind , Force rage , Force stealth , and Hatred , and she was trained in the use of martial arts . Equipment . Ost wielded a lightsaber , which had a bright - pink blade with traces of red . The weapon had a black - colored steel handle and was ignited via an internal switch , through use of the Force . In addition , she carried a blaster pistol as a secondary weapon , and she wore street clothes during her assault on Creautaa - V . Behind the scenes . Crymsin Ost made her first and only canon appearance in " Belly of the Beaast " , a roleplaying adventure written by Morrie Mullins in 2003 that formed part of the Metatheran Caution trilogy of the " Living Force " campaign . During the adventure the player - characters roleplay as the Heroes of Cularin , and the amount of Force powers possessed by Ost varies , depending upon the roleplaying experience tier of the players . She can only utilize the powers Drain Energy , Force rage , and telekinesis , or use martial arts when facing off against players in the middle or upper experience tiers , and she can only wield the power Hatred when engaging upper - tier players . As a consequence , when fighting lower - tier players , Ost has to have her lightsaber ignited for her by Disch ' l , because she lacks the ability to use telekinesis and thus cannot operate her weapon ' s Force - activated switch . It is possible for the player - character to kill Ost during their encounter with her , and also to loot her lightsaber . If she is captured by the players , she attempts to activate the implants in her tattoos and commit suicide .
