The Midnight Exile
The Loyalists were formed upon the enactment of the Midnight Coup by Ghaul, the Consul and his Co-conspirators. Knowing that the act of killing Calus would be too great an outrage to quell, Ghaul and the Red Legion instead exiled Calus aboard his own craft, a titanic prison ship The Leviathan along with any and all supporters of him. It was said whilst the Consul spit in the face of Calus and enjoyed the moment of the Coup all too well, Ghaul refused to look Calus in the eyes presumably out of shame. From here, Calus and his Loyalists would be locked in the area of the Leviathan now known as the Menagerie.
The Leviathan would travel on a predetermined course set to essentially fly it to the furthest reaches of Space. On this course, the Loyalists and Calus would fly past the outer fringes of the Cabal Empire, and to the horrors of primarily Calus, grieve for their home people. What had been the lavish and 'pleasures' of Calus' old Empire, where art was celebrated as much as war had become an industrial, militant, and brutal regime of martial self-sufficiency and grit.
Passing by more of the Empire, Calus and his Loyalists witnessed even the face of the Imperial Navy change from proud, independent cruisers to swarms of ugly and crude frigates and warships. Observing the Red Legion assault a Hive War moon, Councilor Match spoke with many other Loyalists on how the Cabal could fend against the Hive. His answer came from another Psion who believed the Cabal could not beat the Hive, but merely fight them off long enough to live their lives.
The Black Edge
Eventually, after when Calus had stopped cursing Ghaul and the Loyalists had long parted from the fringes of Cabal Space the Leviathan was sudden and abruptly stopped. The Leviathan had come up against an expanse of utter nothingness, at the very edge of the universe, shorting out the navigation systems and the course the conspirators had set. Calus looked into the void and came to an understanding, believing that it had chosen him to herald its inevitable victory. He would watch it consume the light of the universe, and all among the last of the living would know his greatness. While Calus viewed the edge in this way, celebrating it and having it give him newfound purpose and rejuvenation, the Loyalists were terrified by him and thought he had suffered trauma and hallucinations from his pressure suit malfunctioning.
After Calus' and the Loyalists' encounter with the Black edge, it was found the ship had sprung back to life and the Loyalists toiled to undoing the sabotage made by the Red Legion along with seeking to expand the elements of the Leviathan so that they may thrive. With control of the Leviathan back in his hands, Calus set out on a long voyage of his own, "[plumbing] the secret places of the cosmos", visiting strange realms and old ruins. This cemented both his conviction that his hedonistic philosophy was correct and his intent to retake his empire. Along the way, he gathered forces to strengthen his Loyalists.
The Rise of Shadows
Encountering many races, both old and new, such as the Clipse, Sindû, and Arkborn, Calus brought all of them into the folds of his Great Leviathan. He created the Shadows as his elite champions, allied with aliens such as the Clipse and the Sindu, and sent messages promising that whoever slew his conspirators would be given great wealth and glory. To the Clipse, he won their battered war after the Red Legion had abandoned them and brought aboard thousands into newly produced arcologies before obliterating the Clipse homeworld with the guns of Kaga-Clipse. To the Arkborn, Calus threatened them and their interstellar conduits during his exile aboard the Leviathan. One of them, known as The Fulminator, agreed to join him as a Shadow both to keep him away from her people and in exchange for a specially engineered containment suit that would allow her to move freely beyond her ark. Her departure outraged the rest of the Arkborn.
The Failed Assassination
Eventually, he set a course for the Sol system, which the Red Legion was planning to assault. Many celebrations and ceremonies of countless victories were held by the Red Legion. One such ceremony would be interrupted by Rull and his assassination of Iska'al and Moli Imoli with Rull perishing before Ghaul just as he had killed the Everjoy. In the days immediately before the Red Legion set out to the Solar System to wipe out the Guardians, Calus deployed his Shadows to assassinate the various conspirators behind the coup that deposed him. While the Shadows succeeded in eliminating nearly everyone on Calus's hit list except Caiatl, Umun'arath, Otzot (additionally referenced during Insight terminus strike), The Consul and Dominus Ghaul, none of them survived their mission. Although they succeeded in infiltrating Ghaul's vessel, the Shadows perished one-by-one against overwhelming odds. Nohr slaughtered three-hundred of Ghaul's best warriors with her bladed shield before facing off against the Dominus himself. She was the last Shadow standing, and Ghaul killed her, much to the grief of Calus.
Arrival in Sol
Reaching Sol, Calus and the Loyalists learned of other warriors in the system that might serve his purposes. Arriving over Nessus after the death of Ghaul, the former Emperor of the Cabal and his Loyalists arrived in the Solar System aboard their massive craft and immediately set to work on reclaiming the Empire. He gave elements of the leaderless Red Legion the chance to "join the loyalist regime," sending them on missions to collect geological data on Nessus. These Red Legion, those that did not fail, would integrate with the Loyalist regime. Calus would also have Loyalist spies onboard The Almighty called the Crimson Shadow.
Calus extended an invitation also to The Guardian to board his vessel for slaying Ghaul. The Guardians accepted Calus' challenge and following a long journey through Calus' palace and defeating his loyalist army, the Guardians seemingly meet Calus in person in his throne room. Facing off against the exiled Cabal Emperor, the Guardians survive his strange powers and after dealing critical damage to him, they found that the Calus they were facing was really a robotic duplicate.
Regardless, the Guardians succeed in destroying the robot. Before the destruction of the machine, Calus boasted about his power and claims to know the "real truth" about the galaxy and the purpose of the Traveler. Nonetheless, he rewards the Guardians for completing his challenge and offers them a place by his side should they seek him out.
Some months later, Emperor Calus called upon the Guardians again when his Leviathan broke off a chunk of Nessus that contained a powerful Axis Mind, Argos, Planetary Core, thus clogging up the massive vessel. After a perilous struggle against the Axis Mind, the Guardians succeed in disabling its shield and destroy the mind. However, with Argos's shield gone, the Guardians were soon to be devoured by the inferno of the Leviathan. Fortunately, Calus saves the Guardians and rewards them for their success and the Cabal Emperor once again offers them more than just the power of the Light, as Calus demonstrated that he can keep them safe. He also cryptically warns them that the "end" is near and therefore must be ready, as he will find them again.
The Red Siege
Some time later, following the end of the Red War, in the vacancy that was left behind by Ghaul's death, Val Ca'uor took advantage of the power vacuum and quickly asserted himself as the commander of the Red Legion. Under his direction, he hoped to resupply the Red Legion by pillaging Vex technology from Mercury and gather energy from Mars to regain their strength following the failure to capture the Traveler and defeat the Guardians.
After Xol, Will of the Thousands was killed, Val Ca'uor led a fleet against The Leviathan in order to kill Emperor Calus and seize the ship for the Red Legion's purposes. To the Red Legion and Ca'our respectively, the Loyalists and Calus had betrayed the Cabal people and proven themselves as traitors by not assisting the Cabal in the Red War which would have been their Salvation. In a great siege, Ca'our and the Red Legion slaughtered countless Loyalists through their conquest of the Leviathan's internals and Spire. Ca'our had even managed to nearly slay a robotic Calus duplicate before meeting his end by the Guardians. It would later be found out this Raid was unauthorized by the Vanguard and solely Guardians heeding Calus and Calus alone.
It would appear despite the Guardians' intervention, a vast amount of Loyalists had been killed as every proceeding encounter on the Leviathan with the Loyalists afterwards shows far fewer Cabal members.
During the time of Forsaken, Calus had begun to slip some Loyalist spies amongst the Red Legion's ranks such as Taurg, Disguised by the Emperor. Many of these spies were former Red Legion themselves.
Depths of The Menagerie
Prior to the events of Season of Opulence, Calus broke his promise to the Fulminator upon her dissipation. He returned to the interstellar conduits and, with the aid of his Loyalist Councilors, kidnapped many of the Arkborn, imprisoning them within a section of his Menagerie.
His Shadows agents had also lay siege of a lone Hive War moon and uncover an Ascendant Hive artifact called the Crown of Sorrow. Calus' Councilors concluded that the Crown was a two way seeing device into the Ascendant realm, and he later sought out to use it in order to subjugate the Hive under his rule. This however was a desperate ploy by Savathûn, the Witch Queen in order to take control of Calus. But he however saw through this minor trick and didn't have any intention of putting it on himself as he desired a Shadow to do it for him.
Sometime following the Guardians recent battles with the Kell's Scourge and dealings with the Drifter, Emperor Calus was able to create what he believed to be the perfect candidate to utilize the power of the Crown of Sorrow through Gahlran, the Sorrow-Bearer. Though Gahlran was bred to control the artifact to further Calus's goals, he was ultimately consumed by it as Savathûn's influence was too strong for the Shadow, which allowed her Hive to infest the deep treasure vaults of the Leviathan.
Calus called up the Guardians to form a Raid team to purge his space craft of Gahlran and his Hive. The Guardians traversed the treasure vaults and encounter many dangerous Hive rituals but manage to persevere and reach Galhran himself. Despite the Crown granting Gahlran great dark Hive powers, the Guardians managed to slay the Sorrow-bearer, completely purging the Hive from the Leviathan. Calus, pleased with their continued successes, rewards the Guardians with great riches and officially names them one of his Shadows.
However, Gahlran usage of the Crown of Sorrow had caused even worse side effects as its power had unexpectedly tore open rifts into the Ascendant realm centered around the upper decks of the Leviathan. Calus sent his Loyalists to investigate and located the framework of an old weapon of Toland himself. Following the creation of the Guardian's Tribute Hall in commemoration of the Guardian's feats, Calus informed him that an unknown power began to dwell within the Ascendant portions of the Leviathan and tasked them to find the corporeal essence.  After a vigorous battle between the Taken and Cabal within the Ascendant Realm, they would meet with Toland who had asked the Guardian to feed the essence through killing, thus locking the essence back into his creation and claiming the weapon for themselves.
The Guardians accession to Shadow became sour news towards some in the Last City, particularly the Warlock Aunor Mahal, who believed that Calus is subverting the Guardians's priorities, brought her concerns and findings to the Vanguard. She proposed that the Last City should storm the Leviathan and take Calus out before his plans come to fruition. Unfortunately for the Praxic Warlock, while the Vanguard acknowledged that Calus was no ally, he kept the Red Legion in check and supplied the Guardians, nor did they wish to start a war with him. They reasoned that in time, Calus's influence over the Guardians will fall and if the Cabal Emperor does make a wrong move, they will not hesitate to send a strike team. Calus and his Loyalists in the meantime employ the use of Guardians to acquire old relics from Red Legion deserters.
Dawn, Worthy, and Arrivals
After The Undying Mind's final destruction, the timeways over Mercury have been undone and a council of Red Legion Psion Flayers aimed to take advantage of the Vex's disorganization to assume control over time itself and undo their defeat during the Red War. Their meddling with Osiris's time-altering Sundial resulted in Mercury fracturing into three different eras, each with their own timelines dictated by the Psion Flayers. The Guardians team up with Osiris to ensure the safety of time, preserve the present and to save a legend, Saint-14. During this, there were accounts of the Red Legion offering bulk of tribute in the form of Light and Vex technology to other Legions and Calus and his Loyalists themselves. It is uncertain, however, if these offerings extended from the confines of the Sundial or not. Judging from the Red Legion's following play in Season of the Worthy, it can be inferred they did not.
Upon Season of the Worthy, Calus employed a Shadow agent to steal The Fourth Horseman, an infamous Cabal-killing weapon, to eliminate multiple key Red Legionnaires across the system. This Shadow, however, was caught and killed by emissaries of her daughter Empress Caiatl, and the shotgun cached away by the Red Legion (which was recovered by the Guardians once more).
Following the second arrival of the Pyramids in the Sol System, Calus and his Loyalists disappeared along with the Leviathan, abandoning their barge on Nessus. With Caiatl seeking to raise the Red Legion once more and rally the remnants, she has commanded the Legion to seek Calus and the Leviathan and bring them forth to her.
In contrast to the Red Legion, their armor is predominantly purple and gold, and leaves their arms and feet bare. The Loyalists exiled with Calus were all soldiers, and their ranks have since been grown by deserters from the Red Legion.
After the death of Dominus Ghaul, Calus immediately set to work on reclaiming the empire. He gave the now leaderless Red Legion the chance to "join the loyalist regime," sending them on missions to collect geological data on Nessus. These transmissions are intercepted in the Adventure Invitation from the Emperor. Calus intended to convert the soil of the planetoid into "Royal Wine".
Calus extended an invitation to The Guardian to board his vessel for slaying Ghaul. The Guardians accept Calus' challenge and following a long journey through Calus' palace and defeating his loyalist army, the Guardians seemingly meet Calus in person in his throne room. Facing off against the exiled Cabal Emperor, the Guardians witness his strange powers and after dealing critical damage, they find that the Calus they are facing is really a robotic duplicate. Regardless, the Guardians succeed in destroying the robot. Before the machines destruction, Calus boasts about his power and claims to know the "real truth" about the galaxy. Nonetheless, he rewards the Guardians for completing his challenge and offers them a place by his side should they seek him out.
One of the Loyalists's feats in technology would be the development of the Ceremonial Bathers. These trained Gladiators are created through the embryonic pools within the Royal Pools of the Leviathan. One of the most well known Bathers would be known as Gahlran.
Shadows of Calus
The Shadows of Calus are an elite group of Loyalist champions in the service of Emperor Calus, composed of individuals from various civilizations who were personally recruited by Calus during his exile. In the days immediately before the Red Legion set out to the Solar System to wipe out the Guardians, Calus deployed his Shadows to assassinate the various conspirators behind the coup that deposed him. While the Shadows succeeded in eliminating nearly everyone on Calus's hit list except Caiatl, Umun'arath, Otzot (additionally referenced during Insight terminus strike), The Consul and Dominus Ghaul, none of them survived their mission.
In the aftermath of the Red War, Calus had since started auditioning Guardians to replace them as the newest generation of Shadows, starting with a trial through The Leviathan. They would later aid the emperor in clearing his ship of incursions from the Vex, Red Legion and Hive in addition to proving their mettle in the Menagerie; to which the Guardians that succeeded were given the title of Shadow of Earth much to the concerns of the Vanguard and the suspicions of Aunor Mahal.
