Hogrum Chalk Hogrum Chalk was a Human male who served Emperor Roan Fel until Fel ' s death in 138 ABY . Originally one of the Emperor ' s Imperial Knight s , Chalk was maimed in an accident and consequently fitted with a cybernetic suit of life - preserving cyborg armor . He afterward left active service as an Imperial Knight and became the order ' s master armorer ; in his new post , Chalk crafted the armor worn by his fellow Knights . Before 137 ABY , Elliah Fel — Chalk ' s sister and the Emperor ' s wife — was killed by the rogue Imperial Knight Eshkar Niin . Following his sister ' s death , Chalk remained close with his niece , Princess Marasiah Fel . However , he betrayed her father and became a spy in the employ of Grand Moff Morlish Veed . The Grand Moff was an officer in the Sith Lord Darth Krayt ' s Galactic Empire , an organization opposed by Fel ' s Empire - in - exile in the Second Imperial Civil War . In 137 ABY , Chalk was with Fel ' s forces on the fortress world of Bastion , and he constructed a suit of life - preserving armor for Azlyn Rae , an Imperial Knight who had been gravely injured during a battle on the planet Had Abbadon . When the Emperor soon after went to the planet Agamar to negotiate an alliance with the Jedi Order , Chalk informed Veed of the meeting ' s location . The Emperor was subsequently by a Sith – Imperial strike force put together by the Grand Moff , but he managed to escape Agamar with his life . Fel remained unaware of Chalk ' s betrayal and appointed him as the Director of Imperial Intelligence , which gave Chalk access to Imperial secrets , some of which he passed on to Veed . When an Imperial frigate captured the Sith Lady Darth Maladi , Chalk had her imprisoned on Bastion and brought Fel to see her after she , in an apparently crazed state , requested an audience with the Emperor . Maladi claimed to no longer serve Darth Krayt and offered to create a deadly pathogen that Fel could use against the Dark Lord — albeit with high civilian casualties — and Chalk urged Fel to accept her offer . When Krayt unleashed his devastating Sith trooper army on the Empire - in - exile and its allies during an evacuation of the Jedi ' s Hidden Temple , Chalk reiterated his advice , and the Emperor deferred to his wisdom . During an attack on Krayt ' s throneworld of Coruscant , Fel prepared to unleash the pathogen onto the enemy capital , but he was halted and killed by the Imperial Knight Antares Draco , who had sworn an oath to end his Emperor ' s life if Fel ever succumbed to the dark side of the Force . The allies nevertheless won the battle and consequently the war , and at Fel ' s funeral , Chalk delivered a eulogy and announced that the galaxy would be unified under a new Galactic Federation Triumvirate . Biography . Dealing with loss . In the years before 137 ABY , the Human male Hogrum Chalk was a member of the Imperial Knight s , an order of Force - users dedicated to the preservation of the Galactic Empire and the defense of its Emperor , Roan Fel . Chalk ' s sister , Elliah , was the Emperor ' s wife , and Chalk ' s niece , Princess Marasiah Fel , was born before 130 ABY . While active as an Imperial Knight , Chalk was maimed in an accident . He received extensive scarring and was subsequently fitted with a suit of life - preserving cybernetic armor that included a prosthetic left eye . Now a cyborg , Chalk retired from active service in the order and took on the position of master armorer , crafting the armor worn by his fellow Knights . In 130 ABY , the Sith Lord Darth Krayt usurped the Imperial throne from Emperor Fel and drove him into exile . Imperial Knight Eshkar Niin defected to Krayt ' s One Sith at some point before 137 ABY , but first hunted down and killed Elliah Fel . After his sister ' s death , Chalk continued to serve Fel ' s Empire - in - exile in its war against Darth Krayt ' s Galactic Empire , but he also became a spy for Morlish Veed , one of Krayt ' s Grand Moffs . When the Empire - in - exile captured the planet Bastion from Krayt ' s forces in 137 ABY , Chalk joined the Emperor on his new fortress world . Later in the year , Imperial Knight Azlyn Rae was grievously injured by Darth Krayt while battling him on the planet Had Abbadon , and was afterward fitted with her own suit of life - preserving armor by the mechanic " Bantha " Rawk before returning to Bastion . After her arrival at the Imperial capital , Chalk designed new armor for her . While Rawk ' s suit had enclosed her entire body , Chalk ' s design negated the need for a helmet by installing an artificial breathing system in the suit ' s neck . With the design complete , Rae sparred with fellow Knight Ganner Krieg in Bastion ' s Imperial Knights quarters to become more comfortable fighting in her new armor , and Chalk and the Emperor looked on . Fel had recently agreed to meet with representatives of the Jedi Order on the planet Agamar to negotiate an alliance against Krayt ' s forces , and he sought Chalk ' s counsel regarding the meeting . The two walked away from the duel to discuss the upcoming mission . Playing both sides . Chalk contacted Veed and let him know of the meeting ; the Grand Moff accordingly brought a strike force to Agamar with the intention of Fel . Chalk did not attend the meeting , but over ten Imperial Knights were with their Emperor when he and his new Jedi allies were ambushed by Krayt ' s Sith . Several Imperial Knights and Jedi died while protecting the Emperor , who was able to evacuate the planet alongside most of the survivors . Marasiah , Rae , and Jedi Master Rasi Tuum were stranded planet - side , and the Princess was afterward kidnapped by the Sith . Rae and Tuum were able to steal a Sith – Imperial attack ship and return to Bastion . As the vessel approached the Imperial fortress world , Chalk , Jedi Knight Shado Vao , and Imperial Knight Masters Krieg , Antares Draco , and Treis Sinde were roused from their sleep by alarms . They all rushed to a landing platform , where Chalk unsuccessfully attempted to contact the ship . He suspected that it might be piloted by Sith who had tortured proper clearance codes out of a captured Imperial Knight . Rae contacted Krieg via comlink , however , and Chalk ordered Bastion ' s defensive artillery batteries to cease firing on the ship . When Rae and Tuum landed , a furious Draco berated them for not having brought Marasiah with them . The Emperor contacted Chalk at that moment and summoned everyone present to his quarters , and Chalk put an end to the unfolding argument by relaying the news . Inside his quarters , Fel revealed that his sources had told him Marasiah had been taken to the Sith world of Korriban . Draco , Krieg , and Vao were able to soon after rescue her , but Draco was himself captured by the Sith in the process . Shortly afterward , Fel named Chalk the Director of Imperial Intelligence and the head of Bastion security . Chalk contacted the Hapes Consortium and asked if their spies had any news of Draco , but they had heard nothing . Chalk relayed as much to Marasiah when she sought her uncle out on one of Bastion ' s landing platforms during a snowfall . He planned to make further inquiries , however . After the two reminisced together about Elliah Fel , Chalk expressed his regrets that his intelligence duties prevented him from attending an upcoming ceremony being held for Draco and the Imperial Knights who had died on Agamar . Around the same time , Intelligence informed Chalk that an Imperial frigate had found the Sith Lady Darth Maladi lying comatose in a derelict vessel near the planet Vinsoth , and Chalk arranged for her to be secretly transported to Bastion ' s Imperial Dungeons . When Maladi awoke , she appeared to be in a mentally fragile state and began to ramble about a pathogen called Omega Red that could wipe out all life it touched . She also requested an audience with the Emperor . Devil on a shoulder . Meanwhile , Krayt began a renewed military push against the Empire - in - exile and other enemies of the Sith . Chalk looked on as Fel held a holocomm conversation with Imperial Knight Rand Ko , who was leading Fel - loyal stormtroopers in a battle on the planet Borosk . Ko reported that the battle was lost just before the HoloNet connection died , and Fel vocally rued the amount of manpower that Krayt possessed . Chalk thus brought Fel to the Imperial Dungeons and revealed to him the Sith prisoner . A half - crazed Maladi requested safe haven from Krayt , whom she had previously plotted against , and offered to create Omega Red to the Emperor in exchange for the head of Cade Skywalker , a former Jedi who had mentally attacked her with the Force and left her in her current mental state . Chalk and Fel discussed the idea of using the pathogen , and Fel repeatedly dismissed it as too barbaric an act even after several suggestions from Chalk to use it on Korriban and end the war . The two then left the dungeons , and the Emperor ordered Chalk to tell no one of Maladi ' s capture . As Head of Bastion security , Chalk discovered that Nyna Calixte , the Director of Imperial Intelligence for Krayt ' s Empire , was a spy working for Fel and had given him advanced warning of the ambush on Agamar . Chalk contacted Morlish Veed and relayed the information to him , which prompted Veed to attack Calixte in her apartment . As the war progressed , Fel committed a fleet to the defense of the Jedi ' s Hidden Temple from Krayt ' s forces . The battle saw Krayt reveal his secret army of Sith troopers and wreak havoc on the Empire - in - exile and its allies , which prompted Fel to worry that Bastion would be their next target . With their allies en route to the Empire - in - exile ' s fortress world , Chalk and Fel made their way to the Imperial Dungeons , and Chalk attempted to console the distraught Emperor . A determined Fel ordered Maladi to create Omega Red . Antares Draco was among the allies who returned to Bastion , as he had been frozen in carbonite and delivered to Cade Skywalker by the Sith after revealing the location of the Hidden Temple under torture . Chalk and Sinde debriefed him upon his return home . A captured Sith trooper was also with the fleet , and , as it was examined by a doctor in a Bastion operating theater , Chalk , Fel , Sinde , Jedi Master Tili Qua , and Admiral Gar Stazi of the Galactic Alliance Remnant looked on . The trooper revealed that its will — as well as the will of every member of the Sith trooper army — was linked to Krayt ' s own will through the dark side of the Force , and then promptly died . Chalk quietly urged Fel to use Omega Red against Krayt ' s Sith and to launch an attack on their throneworld of Coruscant , else he and his allies would be unable to stand against the Sith trooper army . Fel agreed and told Chalk to keep Omega Red ' s existence a secret . The Emperor was able to convince Stazi and the Jedi Council to go ahead with the attack , and , as the allied fleets made their way to Coruscant , Chalk stood with Fel on the bridge of the " Pellaeon " - class Star Destroyer " Jagged Fel " . Sinde , Marasiah , and Draco were also with them , as the Emperor wanted to be surrounded by those who were most loyal to him . The " Jagged Fel " and the rest of the allied fleets arrived in the Coruscant system just as the throneworld ' s orbital defenses were brought down by an advanced strike team led by Skywalker . During the ensuing space battle , Fel and Draco left the bridge and made their way to an escape pod . When Fel insisted on using Omega Red to defeat Krayt in spite of the billions of innocent lives it would claim , Draco killed his Emperor in a lightsaber duel , fulfilling an oath that every Imperial Knight made to end the Emperor ' s life if he were ever to fall to the dark side of the Force . Skywalker , meanwhile , killed Krayt on the planet ' s surface , and , when the Sith troopers subsequently went insane , the naval forces of Krayt ' s Empire fled from the planet and ceded control to the allies . With the capital won and the Sith in hiding , the war was over . In the battle ' s aftermath , a funeral was held on Coruscant for the Emperor . Chalk delivered the eulogy as Fel ' s body was cremated , praising the Emperor ' s resolve to defeat the Sith and his devotion to the citizens of the galaxy . Chalk also announced the formation of a Galactic Federation Triumvirate — Admiral Stazi , Jedi Master K ' Kruhk , and the newly - crowned Empress Marasiah — that intended to lead a unified galaxy . Personality and traits . Hogrum Chalk was possessed of black hair , black eyes , and fair skin . Following his accident , he received extensive scarring and was fitted with cybernetic armor . Chalk believed that the accident was caused by the will of the Force so that he might go on to develop armor for the Imperial Knights . He was very dedicated to his job as master armorer , referring to the armor he built as his " creations . " He felt that the armor that Rawk had crafted for Azlyn Rae was an unrefined design not befitting an Imperial Knight , regardless of some parts of it that he found impressive . When Chalk was appointed the head of Imperial Intelligence , he displayed similar dedication to his new post . He focused much of his time on directly serving Emperor Roan Fel , actively seeking out information on the missing Imperial Knight Antares Draco and imprisoning Darth Maladi in Bastion ' s Imperial Dungeons . When Fel stewed over the losses incurred by his forces at the Attack on the Hidden Temple , Chalk remained positive and reminded the Emperor of the battle ' s successes , such as the defection of several of Krayt ' s officers to their side . Nevertheless , Chalk betrayed his Emperor and repeatedly passed vital information to Morlish Veed , a Grand Moff in Darth Krayt ' s Empire . Chalk was very fond of his sister , Elliah , admiring her warrior spirit and her loyalty to the Empire . Years after she was murdered , he still regretted her passing and maintained a close relationship with Marasiah Fel , his niece and Elliah ' s daughter . Chalk believed that she embodied the same qualities that her mother had . Chalk ' s opinions were respected and trusted by the Emperor , who felt that Chalk understood the Jedi , and who sought his counsel in preparation for a meeting with representatives of the Jedi Order . Counsel that Chalk provided for Fel during the later stages of the war saw him advocate the use of Omega Red — a deadly pathogen that had the power to wipe out all life it touched — on the Sith world of Korriban . Fel initially refused , but Chalk believed that it could end the Sith Order and ultimately save millions of lives . When Darth Krayt revealed his army of Sith troopers and Fel ' s convictions began to flounder , Chalk continued to urge his Emperor to use the pathogen . Fel ultimately chose to unleash it on Coruscant , which led to his death at the hands of Antares Draco . Powers and abilities . Chalk was sensitive to the Force . Prior to his accident , he was an active member of the Imperial Knights , an organization whose members were considered to be among the most talented and dangerous Force - users in the galaxy . Following the accident , Chalk became adept at crafting armor for the Imperial Knights , and his skills were respected by Roan Fel . Fel later named him the Director of Imperial Intelligence and the head of Bastion security . Chalk remained skilled in the use of the Force while serving in these posts ; he was able to sense the purity of a captured Sith trooper ' s hatred while it was being examined on Bastion . Equipment . Chalk ' s cybernetics covered much of his body . His entire torso , neck , and right arm were enclosed inside of silver and black armor , which included a glowing red panel on his lower chest . He covered his back and the backs of his legs with a flowing , floor - length cape . Chalk ' s armor also covered the back of his head and parts of his face — in addition to circling his exposed right ear , it completely covered his left ear , cheek , and eye , the latter of which was prosthetic and glowed red . A comlink was built into his prosthetic left ear . Behind the scenes . Hogrum Chalk was created by John Ostrander and Jan Duursema , authors of the comic series " " . He made brief appearances in the series ' and issues , prior to its cancellation . Chalk afterward went on to play a much larger role in " Legacy " followup miniseries , " " . The miniseries showed him to be a traitor whom Grand Moff Veed had first mentioned in " Legacy 43 " , but his motivations for betraying Roan Fel were never explicitly revealed . Chalk ' s armor is consistently drawn as completely circling his right ear . However , illustrations of Chalk in the first issue of " Star Wars : Legacy — War " show his armor surrounding only three sides of the ear and leaving the skin below it exposed .
