Sel - Makor Sel - Makor was a mysterious dark side entity that resided in the Dark Heart on the planet Voss . Created when the Jedi influenced the native Gormak by teaching some of them to use the Force , Sel - Makor began to gorge itself on the suffering and anger that resulted from the Gormak rising up against Sith invaders , and soon spread its corruption to form the region known as the Nightmare Lands . Influencing the Gormak into waging war on the newly created Voss , Sel - Makor ' s power and influence spread outward , aided by the various avatars and minions he used as physical forms . When the Gormak king Jokull entered the Nightmare Lands , Sel - Makor gave him the power to see the future as the Voss did , and influenced Jokull to build a starship to escape to the stars and a cannon to destroy the Voss in their mountain city . However , when the Galactic Republic and the Sith Empire began to aid the Voss in their fight against the Gormak , the Voss discovered the existence of Sel - Makor and the truth about their species . Sel - Makor ' s avatars were destroyed at the hands of outsiders , and he was left without a host until the Sith Emperor was lured into a trap by the Sith Lord Darth Baras . The Emperor was imprisoned in the heart of Sel - Makor ' s domain , unable to escape as he battled the entity for control of his host body . The Emperor was freed by his Wrath , who killed the Sith ruler and released the Emperor ' s essence after battling Sel - Makor . Sel - Makor ' s end came at the hands of the Emperor ' s mortal enemy , the Jedi Knight known as the Hero of Tython , and a Voss Commando named Tala - Reh . The Emperor ' s servant Lord Fulminiss enlisted the entity ' s aid in releasing a plague of madness across the planet , but the Mystic Valen - Da manipulated events so that the Hero and Tala - Reh were able to confront Fulminiss at the heart of Sel - Makor ' s power before the plague could be unleashed . When Fulminiss fell in battle with the Knight , Sel - Makor ' s attempts to bribe the Jedi with unimaginable power failed , and the entity was destroyed once and for all when Tala - Reh sacrificed her life to end Sel - Makor ' s own . History . Beginnings . Sel - Makor ' s origins could be traced to ancient times , when the Sith first invaded the planet Voss . At that point , the planet had only one native species , the Gormak , which the Sith ignored as they began to harvest the world ' s resources . However , the planet and the Gormak were irrevocably changed when the Jedi attempted to drive the Sith off of Voss . Seeking allies among the natives , the Jedi agreed to teach some of the Gormak tribes how to use the Force , but the Gormak were unprepared for the knowledge . Those tribes underwent radical evolutionary changes in the course of a few generations , becoming a new species named the Voss . The Jedi attempted to teach the Voss how to control their emotions and new powers , but the Voss instead attacked the Sith on the planet , bringing the new species in contact with the dark side of the Force . This caused the dark side to become manifest in a Sith structure on the planet , and this entity came to take the name Sel - Makor as it gained intelligence . Sel - Makor began to feed on violence and suffering , fueling its dark side powers and spreading corruption across the surrounding area . The entity , which developed a masculine personality , twisted the minds of the animals and beings within his reach , and they became his crazed servants . The area under Sel - Makor ' s control became known as the Nightmare Lands , and the ancient Sith complex that the entity inhabited was known as the Dark Heart . Not long after his creation , Sel - Makor captured the spirits of two of the Gormak who had been taught by the Jedi , Damek - Ol and Nemok - Ta , and imprisoned their spirits in slave bodies . Damek - Ol was imprisoned in the body of a Dashade , while Nemok - Ta was placed in the body of an Abyssin , and the two became avatars of Sel - Makor ' s power . After the extermination of the Sith , the Voss founded the city of Voss - Ka atop the planet ' s highest peak , and the Jedi eventually died out or departed . Those Voss who could use the Force to see into the future became known as the ruling Mystics , and the Voss commandos protected the city . Sel - Makor , meanwhile , influenced the Gormak ' s bloodlust and drove the far more numerous species to attack their cousins throughout the centuries so that he could feed off of their dark emotions . Outsiders . Not long after the Great Galactic War between the resurgent Sith Empire and the Galactic Republic was ended with the Treaty of Coruscant in 3653 BBY , the planet of Voss was rediscovered by the galaxy as a whole . Upon learning of the Voss ' prophetic abilities , the Sith Emperor arranged for an Imperial attack on the planet while his agents kidnapped one of the Mystics . The Voss obliterated the attacking fleet from orbit , and both the Republic and the Empire established diplomatic presences on the planet in an attempt to lure the powerful species from their neutrality . Around the same time , a Sith Lord named Darth Baras began to plot to seize control of the Empire , and so began a long con on the Emperor . Learning of Sel - Makor ' s existence , Baras met with the entity and promised the Emperor ' s powers if Sel - Makor would imprison the Emperor when Baras managed to draw the Sith ruler there . Knowing that his ruler was inhabiting the body of a Voss , as the Emperor existed by possessing hosts known as the Emperor ' s Voices with his consciousness , Darth Baras learned that the inner chamber of the Dark Heart was a place where no Voss could leave after entering . Both galactic powers ignored the Voss ' warnings not to enter the Nightmare Lands as their Cold War continued , and Sel - Makor soon brought those who entered the region under his control . At some point during the Cold War , a Gormak by the name of Jokull entered the Nightmare Lands and traveled to the Dark Heart itself , where he entered the caves known as the Dark Hollow and the Grim Warrens — two of the places where Sel - Makor was most powerful . But instead of consuming the Gormak ' s mind like he had done to so many Voss , Sel - Makor instead chose to awaken within Jokull his species ' natural ability — the power to see visions as the Voss did . Horrified that he had been corrupted and seeing all Voss as being marked with evil because of their powers , Jokull returned to the Gormak Lands and became king of his people in order to wage war upon the Voss — so that the Gormak would never be corrupted like he was . In an effort to gain an alliance with the Voss , both the Republic and the Empire lent aid to the Voss in their fight against the Gormak . The Sith aided the Voss in destroying " Gormegan - 1 " , a starship being built by the Gormak on Jokull ' s orders , and the Republic helped the Voss to destroy the cannon the Gormak were building to use against Voss - Ka . However , in the process , the Voss discovered Jokull ' s ability to see the future , and they enlisted the aid of outsiders in retracing the Gormak king ' s steps in the Nightmare Lands . In the Dark Hollow , an outsider fought and killed the Dashade avatar , while another defeated the Abyssin avatar in the Grim Warrens , and the Voss soon learned the truth of their species ' creation . The Emperor . Throughout the Cold War , Darth Baras began to feed the Emperor information on Sel - Makor ' s powers , tempting the Sith ruler with knowledge of the dark entity ' s mysterious abilities , until finally the Emperor decided to investigate around 3641 BBY . Arriving on Voss in the guise of a Mystic , the Emperor entered the Dark Heart only to find that he was trapped just as Baras had planned . While Baras began preparations to declare himself the Voice of the Emperor and therefore the supreme ruler of the Empire , the Emperor was forced to battle Sel - Makor for control of the Voss body he was inhabiting . Weakened by the loss of his avatars and desiring the Emperor ' s unimaginable power , the entity prevented him from releasing his spirit by committing suicide and attempted to suppress the Sith ' s mind . Fortunately for the Emperor , Baras ' apprentice had been appointed the new Emperor ' s Wrath at the Emperor ' s request by agents of his Hand , and the Emperor was able to communicate his situation to Servant Two of the Hand in a moment of strength . The Wrath , whom Baras had tried to kill at the beginning of his coup attempt , traveled to Voss and was able to locate the Emperor in the Dark Heart after gathering the Blessing of Oneness and the Pendant of Bone needed for entrance . The Emperor ordered his Wrath to kill the Voice and free his essence , but Sel - Makor refused to allow his prize to escape and seized full control of the Voice ' s body . The Wrath was forced to battle the possessed Voice and the dark side phantoms that Sel - Makor conjured , but managed to defeat the entity and drive him out of the Voice long enough to slay the Emperor ' s host . The Knight . After taking a new host on the Imperial capital of Dromund Kaas , the Emperor continued preparations for his ritual , which would consume all life in the galaxy and channel it into the Emperor . To that end , he dispatched the Sith sorcerer Lord Fulminiss to Voss , ordering the Sith Lord to utilize Sel - Makor ' s powers to ensure the thousands of simultaneous deaths necessary to start the ritual . Fulminiss approached a young Mystic named Valen - Da and enlisted his help to enter the Voss sanctuary known as the Shrine of Healing . Valen - Da had experienced a vision of himself and two others standing at the brink of a chasm , and saw that one of them would have to cast themselves into the pit in order to destroy Sel - Makor , agreed to help the Sith because his vision demanded it . In the Shrine of Healing , Fulminiss learned a healing ritual from the spirits of long - dead Mystics , but he corrupted the ritual so that it twisted minds and drove its victims insane . With Valen - Da , Fulminiss followed his master ' s instructions and traveled to the Dark Heart in order to meet with Sel - Makor . However , the Jedi Knight known as the Hero of Tython was attempting to foil the Emperor ' s ritual , and the Jedi tracked Fulminiss to the Dark Heart with the help of the Voss Commando Tala - Reh . The Hero had also killed the Gormak Guardian , a massive vorantikus that Sel - Makor had been using as an avatar to corrupt the Gormak . Upon learning of Valen - Da ' s treachery when the Jedi and the Voss arrived , Sel - Makor ordered Fulminiss to cut down the Mystic . Fulminiss failed , however , and fell to the blade of the Jedi Knight in battle . Valen - Da then revealed the truth of his vision to Tala - Reh and the Jedi : the Commando would descend into the pit before them , the heart of Sel - Makor ' s power , and destroy the entity once and for all at the cost of her own life . In a desperate attempt to save himself , Sel - Makor offered unimaginable power to the Jedi in exchange for casting Valen - Da into the pit , but the Knight refused and watched as Tala - Reh descended the steps to confront the entity . Her sacrifice counteracted Sel - Makor ' s powers , destroying the creature with a burst of golden Force energy and sealing the heart of power when the chamber collapsed onto the pit . Personality and traits . Sel - Makor was born from the dark side of the Force itself , and the entity ' s sole purpose was to cause suffering so that he could spread his corruption further . As he fed off of the suffering created by the conflict between the Voss and Gormak , Sel - Makor ' s driving goal was to prolong that conflict eternally . He had no concern for galactic events , and took no sides in the conflict between the Jedi and the Sith — Sel - Makor attempted to steal the Emperor ' s powers and body , but not long afterwards he worked with the Emperor ' s servant Lord Fulminiss to destroy the Voss and Gormak simply because the Sith sorcerer promised bloodshed and violence . While intelligent , Sel - Makor had a unique way of speaking : he rarely formed complete sentences , instead uttering single words and short phrases in an attempt to communicate . When faced with death , Sel - Makor was unable to defend himself once Lord Fulminiss was killed , and his fear drove him to beg for aid from the Jedi Knight . Sel - Makor offered the Hero unlimited power if the Jedi would kill Valen - Da , but when the Knight refused Sel - Makor was only able to roar in fury and fear when Tala - Reh descended to destroy him . Powers and abilities . An entity formed from the Gormak ' s first contact with the dark side of the Force , Sel - Makor lacked a physical form . Therefore , he corrupted and twisted the minds of those within his realm , transforming them into his servants and spreading the corruption of the Nightmare Lands . Sel - Makor ' s center of power was a deep pit within the Sith ruins that became the Dark Heart , though his reach extended to the edges of the ever - growing Nightmare Lands . The entity also possessed various beings and creatures to serve as his avatars and minions , which allowed him to spread his power and influence beyond the Dark Heart and take a more active role in the corruption of Voss . As a being born of the Force , Sel - Makor possessed immense power , enough to match the Sith Emperor in a battle of wills and the Force . The Emperor , whose own abilities were beyond any other being in existence , was unable to overcome Sel - Makor ' s influence and was instead locked in a stalemate with the entity over control of his body . In battle , Sel - Makor could summon phantoms and his own twisted minions , but without a body or avatars he was largely defenseless . After the death of his avatars , Sel - Makor was unable to stop Tala - Reh from descending into his heart of power — he could only rage at the Voss Commando as she sacrificed herself to destroy him . Behind the scenes . Sel - Makor first appeared in the video game " " , where he is featured throughout several class missions and general missions on the planet Voss . In the Republic quest series , players confront a Dashade " Avatar of Sel - Makor " in the Dark Hollow , and they learn about Sel - Makor ' s past from the spirit of Damek - Ol . Imperial players , on the other hand , fight an Abyssin Avatar in the Grim Warrens and speak to Nemok - Ta ' s spirit . Sel - Makor also appears in the Sith Warrior and Jedi Knight class storylines on the planet — the Emperor is imprisoned by Darth Baras in the Dark Heart , and the Warrior is forced to battle Sel - Makor takes control of the Emperor ' s host body . The Jedi Knight discovers late in the class storyline that Sel - Makor is working with Lord Fulminiss , and after defeating the Sith the player is presented with the dark side option of sacrificing Valen - Da to Sel - Makor instead of Tala - Reh . If the player chooses to kill Valen - Da instead of the light - side option of allowing Tala - Reh to sacrifice herself , then they must kill the Commando when she attacks the Knight in revenge , and Sel - Makor spreads his corruption across all of Voss .
