Rhulk, Disciple of the Witness

Rhulk, Disciple of the Witness is the first of the Disciples: extraordinarily powerful Darkness-wielding entities who collectively follow and do the bidding of The Witness. Hailing from the planet Lubrae, he played a prominent role in the creation of the Hive by subjugating the Worms into servitude of the Witness and then facilitating their production in Savathûn's Throne World, all while keeping tabs on the Witch Queen herself from his own Pyramid.

After Savathûn's rebirth in the Light, he was imprisoned within his own Pyramid by a curse of Light placed by the Witch Queen. However, Rhulk would retaliate by bringing the Scorn into her throne world and subsequently taking command of them. He also serves as the final boss of the Vow of the Disciple Raid where he would meet his demise at the hands of Guardians.

"Mother and the others look at me with concern. Not for my injuries, but for those who suffered at my hands… and they are right to do so. Tearing their bodies to pieces brought only joy. What… am I?"

- Rhulk's thoughts after his brutal killings

Rhulk was born to his father Rhelik and mother Vrhuna on the planet Lubrae, a civilization that had been blessed by the Traveler but fell into a military dictatorship after it left. Rhulk lived with his clan of Wanderers in the Wildlands outside of the sole city on the planet that was controlled by The Regime. The Wanderer clans were subject to frequent dangers, including monstrous wildlife that emerged under the Umbral Sun at night and the Stalkers sent by the Regime to hunt and kill the Wanderers who rejected the city's ways. When he was young, Rhulk witnessed his father kill Stalkers who threatened the clan with a brutality fueled by a bloodlust that Rhulk also felt. He confided in his father about their shared rage and was taught to hate the Regime by him, but when the rest of their clan began to shun Rhelik for his brutality he softened, much to Rhulk's disappointment. His father attempted to teach him patience by making Rhulk watch as other Wanderers were killed by a hunting party of Stalkers and holding him back when Rhulk attempted to intervene. Rhulk was enraged and confused by his father's inaction and believed he was betraying his principals and vows to bring down the Regime.

Although the clan only tried to help others in need of assistance and care for the land, the Stalkers continued to pursue them. During one battle several members of the clan were killed, including Fhent and one of Rhulk's clan-uncles. Rhulk fought back against the Stalkers and killed several of them, claiming their supplies and equipment as his own, including a Glaive and Sapphiric Converter. However, Rhelik was captured during the raid by the Stalkers and the rest of the clan, including Rhulk's mother Vrhuna, looked upon him with only concern and fear due to his brutality during the fight. Frustrated by what he perceived as their weakness, that night as the clan's danced and sang in tribute to their survival and in honor of the dead, Rhulk ripped apart a pet Yhadt that belonged to some of the clan's children. The clan was horrified, and Rhulk felt powerful in that moment but feared that made him a monster.

A year later, Rhulk was forced to live as an exile from his clan due to his bloodlust being viewed as a liability. While the clan had not been attacked again since that night, Rhulk stalked the area around the artificial Abyss which separated the Wildlands from the Regime's city. He hunted the Stalkers with his new weapon and tools seeking any sign of his father in the hopes of rescuing him and bringing him back alive to the clan. He named his glaive Rheliksward in honor of his mission. Although he killed many Stalkers over that year, he found no sign of his father and felt lost without Rhelik's guidance. His search came to an end when he encountered Rhelik dressed in a Stalker's uniform and was captured by other Stalkers under his command. Infuriated at his father's defection to the Regime, Rhulk believed him to be a coward who sought only survival instead of sticking by his principals.

Stalker
"The Regime took all that mattered to you… and yet, you blamed your father?" "The Regime never lied about who they were. They were brutal, yes. But honest." "Honesty meant something to you?" "It meant everything."

- The Witness and Rhulk discuss him joining the Regime

Rhulk was put on trial in the city for his alleged crimes against the Regime, but was spared when Rhelik testified on his behalf and requested that he instead be made to serve as one of the city's Stalkers. This only served to further infuriate Rhulk as he wondered if his father truly cared about their clan and family or if he was only an opportunist who would do or say anything he needed to in order to survive. He swore to himself that he would ensure that Rhelik would die by his hand. However, despite his hatred for his father, Rhulk began to learn more about the city Lubreans and their philosophies. Although he found the government strict in its laws and with power concentrated in the hands of a few, the overcrowded city still had a higher standard of living and comfort than the Wanderers who faced terrible dangers aside from the Stalkers in the Wildlands. He found that the Regime was also honest in its intentions, unlike his father, and his bloodlust was encouraged amongst the Stalkers. They returned his glaive to Rhulk as well, which he renamed to Rheliksbane and took pleasure in how that unnerved his father.

With this new information, Rhulk began to reconsider the conflict between the Regime and Wanderers and realized that both side's hands were stained with blood, not just the Regime's as his father had always taught him. Rhelik eventually confessed to Rhulk that he was not truly loyal to the Regime. Infuriated by his father's continued lies, the two fought, but Rhelik managed to escape from Rhulk and the City. Pursuing his father, Rhulk tracked him to their clan's last refuge in the Wildlands. He found it abandoned but with numerous important personal items and other supplies left behind. Surmising that the clan had fled quickly after his father's return, Rhulk believed that they would seek shelter near the Abyss.

Rhulk found his former clan hiding near the Abyss, with Rhelik seemingly planning on smuggling the surviving Wanderers into the city to live through nearby tunnels. Emerging from the forest to confront them, Rhulk noticed that many familiar faces were no longer amongst the clan, although his father, mother Vrhuna, and clan-mother Kheesa remained alive. His father claimed that they had been expecting Rhelik to join them, and the Stalker was torn between killing them and helping them find a new home. Rhelik and Vrhuna both apologized for their wrongs against Rhulk and expressed their love for him. Vrhuna apologized for exiling him, while Rhelik expressed his regret for indoctrinating him into hating the Regime and claimed that all he wanted now was for their clan to live in peace and safety. Rhulk believed he could see the honesty in his eyes and thought that perhaps that was the path to follow, allowing his parents to embrace and comfort him. However, they took that opportunity to show Rhulk back into the Abyss. As he fell, Rhulk cursed his naiveté and looked at the faces of his clan, which no longer held regret but only relief at Rhulk's presumed end.

Ruiner
"Their folly was their intended salvation. Siphoning light from the Sapphiric Sun itself. I use your Luster. Turn their technology against them, like a backfired pistol. After serving them. Protecting them. Fighting for them. Suffering for them. A shattered sky. A planet convulsing. Tearing apart."

- Rhulk, as he turns the Upended upon Lubrae

Rhulk survived his fall into the depths of the Abyss, although he was badly wounded by the drop. Surprised by his own survival and by the fact the supposedly endless Abyss had a bottom, Rhulk took in his surroundings and found himself in a swampy ruin filled with darkness. He heard creatures approaching, but as they closed in on him Rhulk heard a voice declaring him unbroken. His wounds healed and he watched a being filled with dark luster approach, melting the encroaching beasts away with its very presence. The being declared that it saw Rhulk's own dark luster and the Lubraean questioned what the being was and how it granted him life. The being declared itself opportunity and told Rhulk that he was to be and cause ruin. As the voice faded Rhulk saw its dark luster remain behind and noted how similar it was to that of the Umbral Sun. Rheliksbane, which had been sundered in his fall, was repaired as well by the being and enhanced with its energy. Glancing upward, Rhulk saw the Abyssal Bridge that connected the city to the Wildlands and knew his clan had likely made its way into the city by then. Taking with him the dark luster that remained, Rhulk used his glaive to begin climbing the walls of the Abyss back to the surface, determined that this time he would not show weakness and waver from his desires.

Upon reaching the city, Rhulk hunted down his clan and slaughtered them all, including his mother and father, whom he decapitated. He spared not even the children as the citizens of the city watched in horror of his butchery. The forces of the Regime were horrified by the slaughter in the streets of the city and imprisoned Rhulk, stripping him of his glaive and calling for his execution. However, the dark being assisted Rhulk once more in being freed of his chains and he recovered his glaive, now calling it Lubrae's Ruin, and set out to end his people entirely for their abandonment of him. To do so, he utilized the gifts of the Traveler against his people by harnessing the dark luster to reverse the mechanisms of a machine that drew energy from the Sapphiric Sun to power the city. Doing so destroyed the star and began cracking Lubrae apart. Rhulk was the last one alive, and as he stared into the Abyss he reflected in horror upon what he had done. Dropping the glaive and dark luster he had harnessed, Rhulk dropped himself into the now truly endless Abyss to finish the extinction of his species.

Witnessed
However, Rhulk once again did not perish by his fall into the Abyss. Instead he awoke in a state of confusion as the dark being from before spoke to him. Rhulk despaired in his actions and lamented the destruction of Lubrae, torn between blaming himself the dark being for driving him to his actions. He declared he had been loved and cared for, but the voice questioned who cared for him now. Rhulk answered that there were none left to do so. The voice asked if he still desired to be cared for, but Rhulk could only say he once did. Then the being questioned if he had returned that care, which Rhulk had no answer to. The being then began showing him visions from his past, including when he had first felt disappointment in his father for not fighting the Stalkers, and claimed that he had never being able to return them. Rhulk told the being it had its answer then, but it told him that the answer was not for it, but for Rhulk to embrace.

The being continued to question Rhulk about his past, and Rhulk told it of his parents and clan, whom he dismissed as traitors whom he should have known would betray him as well. As more scenes from his past played out before him, the being claimed it saw a child seeking validation while suffering great loss. It then asked about the shimmering orb that had visited his people, but Rhulk told it that had been long before his time and had left the Lubrae with a divided society in its wake. The being showed him an image of the Traveler, which Rhulk recognized as the shimmering orb from the stories, and he blamed it for providing hope but leaving behind power in the hands of those who desired it but lacked an understanding of what to do with the gifts given. The being forced Rhulk to see once more what he had done to those with that power, and he again lamented his destruction of Lubrae, but the being reassured him he had only done what was needed.

Fundament
Rhulk would later serve as the Witness’ instrument in subjugating the Worm Gods, forcing them to serve the aims of the Darkness. He swam into the depths of Fundament, meeting the Leviathan on the way and grievously injuring it by removing one of its ribs. Upon finding the Worm Gods at the core of the planet, he created a strain of miniature versions of the Worms by taking pieces of the worm god’s mother, Xita, the nurturing in which their so-called "larvae" could be implanted into a host. He then left the Worm Gods to be found by the Krill, who would then become the Hive, abducting their sixth member and mother, Xita, the Nurturing Worm in order to use her to breed more Worm larvae.

Savathûn's Throne World
At some point Rhulk was ordered to station his Pyramid in Savathûn's Throne World, assisting Savathûn, the Witch Queen in the production of Worms for her brood. After her claim of light, he would be trapped within the Sunken Pyramid, blocked off from the rest of the realm thanks to her usage of the Wellspring. After Savathûn’s defeat by the hands of The Guardian, who was attempting to free the Traveler, along with numerous raids on the Wellspring by both the Guardians and the Scorn, the spell that once trapped Rhulk would begin to fade. Eventually the spell would break as the Guardians attempted to investigate the sunken Pyramid and were greeted by the Disciple, who invited the fireteam to enter. The Guardians were opposed by both Scorn and Taken forces marshalled by Rhulk, as they journeyed through the Pyramid, encountering Rhulk's vast collection of museum artifacts, including the rib he took from the Leviathan of Fundament, and The Caretaker, a Scorn Abomination Rhulk had infused with Worm larvae to grant it incredible power. After they reached him, he would see no use in them anymore and sought to eliminate them, resulting in a climactic battle. Though it was not an easy task, they would finally bring down and kill the Disciple, with Rhulk's last words asking the Witness for forgiveness.

As he died, Rhulk's body was contorted into what appeared to be a gnarled, leafless tree. The significance of this transformation is yet unknown.

Personality and Traits
Rhulk seems to be completely devoted to the Witness and despises the Guardians for the usage of Darkness. He is mildly egotistical, thinking he is above all who oppose him and even taunts the Guardians while fighting them. It seems that while in the Pyramid, he befriended the worm familiars and the Worm God, being the one who would have to create the worms for Savathûn's brood. He seems to like experimenting with the worm familiars as well, as in the Acquisition section of the raid, you can see frozen Scorn in containers with worms attached to them. These experiments may have failed.

Trivia

 * Rhulk's memories are the source the Glaive weapon class, as the Enigma was crafted by the Relic on Mars from an ancient fragment of a Glaive associated with Rhulk.
 * If one looks closely at Rhulk's six glowing "eyes", one can see that his top left eye is a symbol resembling that of the astrological symbol for Eris, while his middle-left eye resembles the split-circle symbol seen on the attire of both Elsie and Ana Bray. The remainder of his eyes resemble eight-pointed starbursts. The significance of these symbols in this context is unknown.
