Banished

"I've gathered this crew and they're loyal, because I am loyal... and because we share a vision. One where the blood we spill and the treasures we plunder are in the name of our own free will and nothing more."

- Atriox explains the Banished's mission statement to the Silent Shadow.

The Banished are an organization of mercenary raiders that broke off from the Covenant Empire to rebel against it and rose to power after the conclusion of the Human-Covenant War. They were formed and led by the Jiralhanae warmaster Atriox. The Banished are primarily composed of Jiralhanae and have incorporated Sangheili, humans, Mgalekgolo, Unggoy, Huragok, and Kig-Yar, as Atriox saw feuds segregating species to be a senseless restriction in the way of gaining rewards and treasures. The organization's goals have been described as attaining power in their raids across the Orion Arm, while their killers and mercenaries plunder treasure in the name of their own free will.

Early years
"Atriox and his Banished raided Covenant resources, cutting a swath across the galaxy... Growing in strength with each attack... Gathering killers and mercenaries to his side. The Covenant had two targets in those years. Humanity and Atriox. They almost got us. But Atriox? They never came close. The whole damn Covenant couldn't contain him at the height of their power."

- Isabel tells the origin of the Banished.

The Banished were formed around 2549, during the Algolis Invasion in the late years of the Human-Covenant War by Atriox, Decimus, En'Geddon and several other disgruntled Jiralhanae who rebelled against their Sangheili masters, after being used by the Covenant as cannon fodder repeatedly. After establishing their group, the Banished started off as little more than raiders and pirates, conducting surgical raids against the Covenant and other targets while scavenging for resources and gathering mercenaries to their cause. Evading Covenant enforcers led to Atriox prioritizing stealth in his forces. One such attack was on a Covenant training camp in 2550, Atriox and the Banished killed the Sangheili guards and stole everything they could including vehicles and weapons. By this point the Banished had attacked at least five other Covenant bases.

Unimpeded by the Covenant's devastating Great Schism, the Banished managed to salvage many of the empire's former assets after its fall, growing into a formidable power in their own right after a decade. While Atriox had already recruited many allies during the Covenant War, the Banished gained many new members in the war's aftermath from former Covenant who wished to continue living as warriors, and additionally renegade humans.

Expansion
"Vengeance is petty. Vengeance has no reward."

- Atriox attempting to recruit Resa 'Azavayl, pointing out the futility in feuds between species.

Decimus advised Atriox that the Banished should travel to the planet Otraak to recruit an old friend of his, a Kig-Yar T'vaoan scientist named Sig Raan. Decimus was sent to investigate first, where Sig Raan initially welcomed him and his squad showing off her latest invention: a device that could control the Yanme'e by simulating their queen's pheromones. Sig Raan then attacked Decimus with her Yanme'e swarm. Atriox showed up along with more of his Banished forces and attacked in Sig Raan in return. Decimus killed her, putting an end to the skirmish.

Following the Great Schism, some Sangheili continued their genocidal campaign against the Jiralhanae out of hatred. One such group was Resa 'Azavayl's Elite squad of the Silent Shadow. After slaughtering various Jiralhanae packs across various solar systems, the Silent Shadow boarded Atriox's Elegy's Lament. The Silent Shadow slaughtered several of the Jiralhanae crewmen aboard, until they encountered Atriox who talked them down. Atriox stated that he and the Banished were different from the Jiralhanae led by Tartarus and the High Prophet of Truth, who had betrayed and massacred the Sangheili. Upon hearing this distinction, 'Azavayl's squad began to see the Banished as "other". Atriox then told them that they should rejoice that the traitorous Covenant was no more and invited them to join the Banished, to which 'Azavayl's squad expressed they were open to. 'Azavayl himself continued to harbor hatred toward Atriox for being a Jiralhanae, to which Atriox dismissed that vengeance was petty. 'Azavayl attacked Atriox but was killed by his Silent Shadow brethren who wanted to join the Banished. Atriox happily recruited them.

After having successfully persuaded among the most vengeful of the Sangheili, 'Azavayl's Silent Shadow squad, Atriox confidently sought out the powerful Enduring Conviction and its Sangheili crew. He devised a plan to meet with its Sangheili Shipmaster, Let 'Volir. Atriox and his Banished attacked a Sangheili-led base on Kostroda, resulting in 'Volir and his forces deploying to the base to defend it. This left Enduring Conviction vulnerable for a separate Banished strike force to raid and capture the mostly vacant ship. Back on the ground, Atriox surrendered himself to 'Volir after seemingly losing the skirmish at the base, and was brought back up to the bridge of Enduring Conviction as a prisoner. On the bridge Atriox had his second team of Banished revealed themselves, ambushing 'Volir and turning the tables. Now as prisoner of Atriox, 'Volir was offered a chance to join the Banished and allow his crew to live a new life as mercenaries and be provided with resources, rather than be used as cannon fodder for the Sangheili-Jiralhanae conflict. After being persuaded, 'Volir had Enduring Conviction abandon their Sangheili-led fleet. 'Volir and his crew would later pledge their allegiance to the Banished, albeit reluctantly, in return the Banished supplied their ship with fuel. The Banished would later use similar methods to hire Thav 'Sebarim's clan and Inka 'Saham's crew as mercenaries as well.

Atriox's Chieftains led divisions of Banished into Jiralhanae colonies and human criminal enterprises to build connections and spread their influence. Atriox was open to recruiting capable assets of any species and several humans had joined the Banished. As the city of New Mombasa began reconstruction on Earth, Banished human mercenary groups would flock to the city for opportunity.

A veteran Jiralhanae Chieftain known as Jovus had made a name for himself as a warlord after the Covenant's fall, which drew Atriox's attention. The Banished sought to recruit him along with his pack, thus Shipmaster Let 'Volir invited him via video transmission to meet Atriox. Like many Jiralhanae, Jovus was confounded that Sangheili and Jiralhanae would overlook their feud and band together but he accepted the offer to meet Atriox regardless. After a tense meeting, Jovus was killed when he tried to attack Atriox.

In 2558, a Jiralhanae in Hekabe's clan suggested hiring the Banished after gaining control of the Sharquoi, to move their new weapons as they needed slipspace-capable vessels and their own had been destroyed. However, Hekabe refused the suggestion, unwilling to share power with Atriox and the Banished when he wanted it all for himself. A dispute led to Hekabe killing a Banished Chieftain known as Odanostos. The Children of Oth Sonin led by Lydus, one of the strongest Jiralhanae governments, secretly hired the Banished as a mercenary military to take out his rivals in exchange for using his shipyards and land.

Occupation of the Ark
"In the shadows of the Ark lurked a banished legacy of the shattered Covenant: a new opponent fueled not by religious fervor, but by raw lust for power."

- Curator's update on the Banished.

Atriox and the Banished took a fleet led by their flagship Enduring Conviction to the extra-galactic Forerunner structure known as the Ark, with a force comprised of Jiralhanae, Sangheili, humans, Unggoy, Mgalekgolo, and Huragok. They attacked a UNSC research facility on its surface, leaving no survivors but Isabel, a smart AI. In March 2559, 28 years after the lost contact with the rest of the United Nations Space Command, the vessel arrived at the Ark to find Isabel in the raided outpost. After the crew's Spartan-IIs encountered Atriox in the facility and were chased away by him, the Spirit of Fire engaged the Banished in combat.

Opening engagements
Captain James Cutter and Isabel decided to strike at the Banished by attacking a salvage operation, in which a group of Banished led by War Chieftain Decimus, Atriox's right-hand man, searched for supplies among the wreckage left from the battle nearly seven years earlier. The UNSC forces managed to destroy the operation despite orbital support from the CAS-class assault carrier Enduring Conviction, the Banished flagship, although Decimus escaped.

From the wreckage of the fight, the UNSC discovered evidence of a Cartographer, a repository of data about the Ark's systems. As the Spirit of Fire sent Marines led by Spartan Jerome-092 to secure an elevator leading to the Cartographer, the Banished troops in the area were attacked by Sentinels. The survivors were unable to stop the UNSC forces from gaining access to the Cartographer.

Meanwhile, the Banished fell victim to a series of hit-and-run operations conducted by Spartan Alice-130, who was trapped behind enemy lines at the start of the battle, and liberated many captured UNSC troops.

The UNSC managed to capture the Cartographer and Professor Ellen Anders determined that the Banished were using the Ark's vast portal network to rapidly transport troops across the installation. The Banished forces at the network's control hub, led by Decimus, failed to prevent UNSC troops led by Jerome and Douglas-042 from destroying the hub, crippling the network. Decimus himself attempted to avenge the loss of the portals, but was killed by the UNSC forces.

The Banished then went on the offensive, launching an all-out ground assault on Alice's forces and sending several waves of Banshees from the Enduring Conviction at the Spirit of Fire. Alice managed to survive, but the Spirit of Fire was seriously threatened, as several of its deck turrets had been destroyed. Several Banished troops were diverted from the carrier's gravity lift in an attempt to stop UNSC forces led by Douglas from using a Forerunner particle cannon to disable the carrier's energy shields. The UNSC was ultimately successful, however, and Jerome and Isabel approached the ship's grav lift, intending to board the vessel and destroy it from the inside out. Their dropship was shot down by Banished anti-aircraft turrets as it approached, but they survived and Alice managed to use Kodiak artillery vehicles to destroy the Banished defenses to clear a path for them to board. On the ship, Isabel managed to fire the carrier's energy projector at the Ark's surface. The resulting damage caused swarms of Sentinels to crash themselves into the carrier, bisecting it. Jerome and Isabel were able to land safely on the Ark.

A new Halo ring
Atriox met with Shipmaster Let 'Volir, who survived his ship's destruction, on the Ark's surface, to assess the situation. They observed a new Halo ring rising from the Ark's Foundry, which the UNSC intended to disarm before sending it to the Soell system in the Milky Way in order to contact the rest of the UNSC. Atriox ordered 'Volir to send his surviving men onto the ring to capture it in a chance for redemption. However, Alice and Douglas led Marines in capturing a portal at the Foundry which the Banished were using to send troops to the ring. The Spartans went through the portal and it was destroyed afterwards to limit the Banished presence on the ring.

Atriox contacted Capt. Cutter and offered him a deal: the Banished would allow the Spirit of Fire to leave the area unharmed if the UNSC surrendered the Halo ring to him. He was refused, with Cutter reminding him that he did not make the same offer to the scientists at the Henry Lamb Research Outpost. The Banished troops on the ring were unable to stop Professor Anders hijacking a Retriever Sentinel in order to destroy a shield which the Banished had erected around the installation's Control Room.

The Banished launched a last-ditch assault to stop Anders from disabling the ring's firing systems and planting a distress beacon. However, a stiff UNSC defense did not break, allowing Anders to finish her work. Once this was done, Anders accessed the ring's gravity anchors and ejected a portion of the landmass, which was occupied by the Banished, into space. The Halo ring then entered Slipspace after all of the UNSC troops were evacuated. However, Professor Anders was stuck on the ring. Cutter resolved to continue fighting the Banished on the Ark until Anders returned. Meanwhile, although Atriox's forces had been devastated by the combined losses of Decimus, the Enduring Conviction, and the Halo ring, the warlord still commanded an impressive army with which to fight the UNSC.

Operation: SPEARBREAKER
One month later, Colony, a pair of Mgalekgolo who command all Lekgolo forces in the Banished, attempted to launch a Forerunner to destroy the Spirit of Fire. This plan was thwarted by Sunray 1-1, a team of UNSC Orbital Drop Shock Troopers from Boomerang Company.

Yapyap's rebellion
During the battle, an Unggoy named Yapyap the Destroyer rebelled against the Banished with his subordinates. Many Sangheili and Mgalekgolo also defected and joined the rebellion. The Throne of Woe was established as their new headquarters. Following Yapyap's lead, they intended to locate the fabled Golden Methane Hydrate Mines of Sabator.

Awakening the nightmare
After months of battle with the Spirit of Fire, the Banished were still searching for victory against the UNSC crew. They unintentionally released the Flood, few of which had survived the destruction of High Charity and the faulty firing of the unfinished Installation 08 at the end of the Human-Covenant War. Pavium and Voridus were sent to scavenge old Covenant ships. Despite being told to not investigate the rubble of High Charity, Voridus breached the containment field around the wreckage anyway. This unintentionally released the Flood onto the Ark. Despite nearly being overwhelmed, Voridus and some of his forces survived and reunited with Pavium. The two began thinking of a way to fight the Flood. Knowing they were underground, they decided to use the drills to ignite explosive materials in the ground to buy them time.

After successfully fighting off the Flood and activating the drills, many of the Flood were destroyed by the resulting explosions. With the Flood temporarily weakened, Voridus and Pavium decided the next step was to reactivate the Sentinel Defense Network Voridus had shut down to get to High Charity in the first place. Voridus was chosen to go underground and reactivate the systems, while Pavium stayed up top with the majority of the forces to hold the line. Voridus was accompanied by a small group of soldiers to assist him, consisting of Sangheili Rangers and Jiralhanae Jumpers. They soon found out the Jumpers were crucial to traversing the Forerunner pathways. Despite their small numbers, Voridus' infusion gel helped slow the tide of Flood from overwhelming them in several encounters. Occasionally, Pavium was able to send small groups of troops down to help Voridus through scattered teleporters, but he could not spare many due to his defense against the Flood. Despite the long odds, Voridus and his surviving troops made it to the sentinel activation terminal, but found it covered in Flood biomass. Both Brutes took note of how the Flood seemed to know the defense system was dangerous to them. Pavium decided to send down Voridus' own special grenadiers powered by infusion gel and offered any amount of soldiers Voridus needed to clear out and reactivate the system. Despite stiff Flood resistance, Voridus cleared the biomass, and protected the nodes from being clogged up again. After reaching full power, he re-aligned the system, reactivating the sentinel network.

Voridus used the teleporters to reach the surface and reunited with Pavium. The two decided it would be wise to inform Atriox of what was going on. Atriox was furious at them, as he would now have to give up a lot of ground they had earned in the conflict with the Spirit of Fire to assist them in suppressing the Flood. He ordered the two to have the problem fixed by the time he arrived or he would kill them himself.

With the survival of the Banished and their own lives at stake Pavium and Voridus led all of their forces deep into Flood territory. Noticing the Flood's increase in tactical ability and intelligence, Pavium realized that a Proto-Gravemind must have formed and was commanding the Flood. He also realized that if they did not kill it soon it would become a Gravemind, at which point the Flood would be nearly unstoppable. They threw everything they had at the Flood and the Proto-Gravemind, which had emerged in the Flood badlands. The Proto-Gravemind used its tentacles to block the Banished forces from reaching it, but Pavium's Mega Turret was able to blast the tentacle away. Finally in range of the Proto-Gravemind, the Banished forces attacked its hard shell, exposing small bulbs. When they were destroyed, the Proto-Gravemind slightly retreated, but exposed its mouth to damage. The Banished fired everything they had, but the beast closed its mouth. Unable to damage it further, Pavium set up another Mega Turret nearby, which opened fire on the beast. The damage was enough to force the Proto-Gravemind out of its defensive state. They attacked the monster again, while holding off ever-increasing Flood forces. This process was repeated several times, adding more Mega Turrets to the barrage every time the Proto-Gravemind went into its defensive position. All the while, it was slowly reaching Gravemind status, but with the constant attacks it could not add enough biomass to reach that state. Pavium and Voridus noticed it was not taking significant damage despite their ever increasing firepower. Pavium decided to call upon a Retriever Sentinel by activating a nearby node specifically meant to control one. With its help, plus the Mega Turrets and Banished forces, the Proto-Gravemind finally succumbed to the damage and was obliterated.

Pavium and Voridus reveled in their victory, roaring to the sky, but the celebration was cut short when Atriox landed nearby. Despite Voridus' inability to follow orders, Atriox allowed them to live because they had shown their worth by fending off the Flood with limited resources. During his inspection of their work, a Pod infector attacked him, but Atriox grabbed it midair with his gauntleted hand, crushing it a second later. However, this didn't stop Atriox from reprimanding the brothers for letting the Flood out of High Charity. He then commanded Voridus and Pavium to secure the breach and clean up their mess while standing menacingly over the former, as thousands of Sentinels began cleansing the surrounding area of the Flood.

Following the incident, Pavium and Voridus' clan, the Long Shields, had lost reputation. Of the Banished's many humans, fifteen were under their command. A few defected to the UNSC shortly after the Flood outbreak, leading Pavium to preemptively kick out the rest in his clan and killing some in the process. Atriox was upset with Pavium's decision as he saw all Banished humans as valuable assets.

Portal to Reach
A Banished force allied with the Jiralhanae legions Keepers of the One Freedom, the Legion of the Corpse-Moon, and the Ravaged Tusks, were deployed to the glassed surface of Reach to search for a slipspace portal which would allow Atriox to return to the Milky Way from the Ark, under the orders of War Chief Escharum. They successfully located the portal and activated with the help of the Ferrets who were undercover in the Keepers of the One Freedom, allowing Atriox to return to the Milky Way in a Eklon'Dal Workshop Lich. However, Castor of the Keepers of the One Freedom betrayed the rest of the Banished by going rogue and taking his forces to the Ark, with the aim of activating the Halo Array himself.

Although Atriox's stated intention was to return to the Ark with reinforcements, he departed with Escharum and his other forces in an intrusion corvette to attend to a greater purpose, leaving thousands of Banished troops behind to hold the Ark. With the slipspace portal bound to catch the attention of Cortana, Atriox and Escharum left Castor to escape Reach before a Guardian Custode arrived to investigate.

Stopping the Ark from activating
Utilizing the opportunity presented by the opening of the slipspace portal, Castor led the Keepers of the One Freedom to the Ark to fire the Halo Array where both the UNSC and Banished forces under the command of Pavium and Voridus sought to foil them, indirectly aiding the Ferrets in eliminating the majority of the surviving Keepers. However, in the process, the Banished inadvertently got in the way of the UNSC's plan to finally destroy Intrepid Eye. The Banished suffered heavy losses in the effort, but both Pavium and Voridus survived while the destroyed the installation that the Keepers intended to use to fire the Halo Array and Intrepid Eye along with it. The brothers intended to report to Let 'Volir that their efforts had delayed the Keepers long enough for the humans to launch their strike.

Occupation of Zeta Halo
"This Ring is different. It has secrets within... that I will have!"

- Atriox seeking to free the Xalanyn.

The Banished had united many Jiralhanae clans across Doisac and its moons, though not all clans. Many clans, including those on Warial, continued to resist the Banished. While Jiralhanae infighting persisted, the Banished staged a defensive against the Created.

Atriox had also learned of the Harbinger during his time on the Ark, and sought to free her species, the Xalanyn, to aid him. Upon the warmaster's return, the rogue AI leader Cortana ordered him and the Banished to surrender, and destroyed Doisac in response to his refusal by firing beams at it with several Guardians.

Following the loss of their home planet, Atriox and his Banished arrived at Installation 07 where the Xalanyn species were secretly hidden. In December 2559, the Banished ambushed the above Installation 07 to retrieve CTN 0453-0 in order to defeat the rogue Cortana and her Created empire as well. The Banished would come to occupy the ring and establish themselves on it.

Opening engagements
Several Banished dreadnoughts attacked the Infinity, sparking a space battle. The dreadnoughts rammed into the UNSC supercarrier, sending it crashing toward Installation 07 in four minutes. The ship was boarded by Atriox and other Banished forces during the attack. He dueled Master Chief Petty Officer John-117 and emerged victorious after tossing the Spartan-II into space. A few surviving UNSC forces of the devastated fleet managed to escape to the surface of the ring and would continue to engage the Banished in guerrilla warfare.

After Atriox arrived at the surface of Installation 07, he confronted Cortana who had been locked down by CTN 0453-0, a UNSC infiltration program also known as the Weapon. Now a prisoner of Atriox and unwilling to give him the secrets of the ring, Cortana detonated part of the ring to prevent him from controlling it, seemingly killing the Banished warmaster in the process. Atriox was thought to be dead, leaving War Chief Escharum in charge of the Banished who were stranded on the ring once it suddenly moved its location.

Escharum's Banished
Despite the fact that Atriox valued Banished humans and made statements denouncing genocide as "barbarism" with "no reward" which allowed the Banished to incorporate feuding species in the first place, Escharum decided to go against Atriox's core beliefs that tied the Banished together and suddenly declared humanity's destruction. Radically altered, the Banished under Escharum's leadership would expend valuable resources on revenge and his desire for a glorious battle, opposed to pragmatism. Escharum's Banished spent their resources to reform Installation 07 for the alleged purpose of "activating this ring", a decision which would ultimately lead his forces stationed around the shattered islands to ruin with many high value leaders dead in the ensuing conflict.

Escharum fulfilled part of Atriox's will by awakening the Harbinger, albeit using her for the reformation of Installation 07. The Banished were complimented with her Gasgira troops known as Skimmers.

During May 2560, the Banished ship Ghost of Gbraakon was destroyed by John-117, who had survived in space and been rescued by Echo 216. Escharum was invigorated by his survival and welcomed him to a battle on his ring world. The Banished bases Outpost Tremonius, Tower, Annex Ridge, Armory of Reckoning, Forge of Teash, Horn of Abolition, Ransom Keep, Redoubt of Sundering and Riven Gate all fell to John-117 and the Marines he freed during the conflict. All high value members situated around the floating islands, many of which served as Bloodstars, were assassinated by the Spartan-II, along with the Hand of Atriox who were sent to kill him.

Seeking a legendary battle or a glorious death with his illness progressing, Escharum sent Blademaster Jega 'Rdomnai to kidnap Echo 216 to lure out the Spartan. Taking the bait, John-117 arrived for the final showdown at the House of Reckoning. Waves of Banished fought against John-117, only to be struck down. Jega 'Rdomnai fought him as well and was defeated. Escharum revealed himself to the Spartan in the room where Echo 216 was being held and a duel took place. Escharum and John-117 took shots at each other until the War Chief resorted to using the room to power a dome-shaped shield to protect himself. The Spartan deactivated the shield and continued to attack, resulting in Escharum pulling out his gravity axe for an even closer battle. After sustaining enough damage Escharum collapsed and told the Spartan that his death would inspire others before dying in his enemy's arms.

The Harbinger would continue leading the remnants of Escharum's local forces, some Banished Jiralhanae saw his death as martyrdom and proclaimed to fight in his name. In a last ditched effort to protect the Harbinger in the Silent Auditorium's central chamber, they attempted to defend her against John-117 where they were all killed along with her. After the Harbinger's defeat, other Banished forces remained in control of different parts of the ring.

Atriox's return
Unbeknownst to both the Banished and the UNSC, Atriox had survived his apparent destruction by Cortana, and had discovered the location of the cylixes in which the Forerunners had imprisoned the Xalanyn. Several Banished affiliated human mercenary groups continued to operate in the crime-ridden streets of New Mombasa on Earth, capitalizing on the city's proximity to Forerunner secrets for Atriox and the Banished.

Governance and society
"In theory, all who can aid Atriox's ambition and will bend the knee are welcome, from human to hunter, but their violence and conditions of service limit recruitment opportunities."

- A description of the Banished's society, from the Spartan Field Manual.

As a mercenary organization, the Banished are essentially a military hierarchy led by Atriox. Their prevailing philosophy appeared to be one of ruthless pragmatism, with their operations focusing solely on accruing useful resources for their war machine. Their overall goals ostensibly center around increasing their power through raiding and conquest, with Atriox having laid plans for dominance across the Orion Arm. During the Covenant's reign, the Banished mostly laid low and kept on the move, never claiming territory; Atriox only attacked targets he had something to gain from, largely in the form of supplies and materiel. However, the Covenant did not seem to have been Atriox's ultimate target, instead only being leveraged as a source of supplies to raid. ONI operative 'D' speculated that Atriox was planning to stabilize the Jiralhanae on their homeworld Doisac under his leadership, though his colleague 'S' disagreed and suspected that Atriox was recruiting and his long-term goals were even more ambitious.

Though the bulk of them are Jiralhanae veterans of the Human-Covenant War, the Banished reject the Covenant's species-based caste system, any species in the Banished can rise through the ranks if they prove their merit and even Unggoy such as Briglard can make a name for themselves. Their chain of command, predominantly composed of Jiralhanae, is a "twisted meritocracy" in which Atriox's subordinates constantly compete for influence and favor in their warmaster's eyes, in hopes of increasing their own status. Atriox has spies across his command hierarchy to snuff out signs of disloyalty, and his inner circle of loyal chieftains, known as Atriox's Chosen, are used to enforce compliance among the higher ranks. Societal conditions within the Banished reflect their harsh values, and most of the organization's members are mercenaries and killers. The Banished are thoroughly irreligious, and lack taboos regarding the treatment of Forerunner technology, though Decimus in particular secretly harbors a reverence for the Forerunners. Atriox and Decimus hate the Covenant's successor factions that uphold its oppressive ideology and structure, while such remnant factions deem the Banished to be repulsive infidels. In addition to the core group of the Banished led by Atriox and Decimus which includes the Clan of the Long Shields among other clans, affiliated clans have also been absorbed into the Banished and reformed as military legions, such as the Legion of the Corpse-Moon and the Clan of the Ravaged Tusks. While Atriox and Decimus' mercenaries were all outfitted with red and gray Banished armor and vehicles, affiliated mercenary clans during the Zeta Halo conflict typically reused standard former Covenant armor that had been salvaged and the usage of official Banished armor was limited to higher ranks.

Atriox did not care for the greater Sangheili-Jiralhanae feud, As such, he has welcomed some Sangheili to join the Banished as mercenaries. Because Atriox and the Jiralhanae in the Banished claim to not have been involved in the betrayal and massacre of the Sangheili, some Sangheili have willingly accepted the offer, and joined viewing the Banished as "other". Three Special Operations Sangheili from the Silent Shadow, a former Covenant Special Operations unit, were successfully convinced by Atriox to join the ranks of the Banished. Additionally, the Sangheili crew of the Enduring Conviction joined the Banished since its shipmaster, Let 'Volir, reluctantly aligned himself with Atriox. Atriox's charismatic leadership allows for both Jiralhanae and Sangheili to be deployed simultaneously, whereas other leaders would struggle to get such bitter rivals to coopererate. Despite this coexistence, hatred between the two species still manifests. The Sangheili under Decimus' command were treated with resentment and often sadistically sent on suicide missions. This is due to some Jiralhanae (including Decimus and Teranus) still holding a grudge against the Sangheili for treating the Jiralhanae as inferiors during the time of the Covenant. Concurrently, Let 'Volir's Sangheili crew feel a strong hatred toward Atriox's Chosen Jiralhanae.

Atriox harbors no animosity towards humanity, and has recruited humans into the Banished. While some humans have joined, the Banished's violent culture and conditions of service make them unattractive to many. As Banished chieftains have spread their power beyond Jiralhanae colonies and into human territory, human criminal enterprises across the Orion Arm have been influenced. Entirely human-led clans would also join the Banished, such as the Order of Harmony. The Banished have also looked through the black markets on the colony of Venezia to trade with humans and sought Forerunner technology, which their shield generators utilized, as well as purchase nuclear weapons. While battling with the during the Second Ark Conflict, Atriox utilized Banished humans in his forces and also admitted respect for his UNSC enemies' tenacity to the point of offering them a chance to leave peacefully without being hunted down, Captain James Cutter refused the offer however. Despite Escharum's personal hatred for humanity, he showed respect for Spartan John-117 as a warrior due to his legendary reputation, to which the Chief would return by listening to and holding him in his dying moments.

The Banished have numerous Unggoy in their service. They are generally regarded as mere cannon fodder and are often abused for sport by their Jiralhanae superiors. A number of "thrall colonies" exist where Unggoy are bred, only to be indoctrinated into the service of the Banished; the most violent individuals are set apart and formed into suicide squads. The Banished have amassed a small complement of Huragok; those serving on the Ark are imprisoned in harnesses equipped with control yokes keeping them in constant agony to keep them compliant, lest they be distracted by their innate need to repair damaged Forerunner technology. The Banished also field Mgalekgolo troops, many of whom are unusually violent for their kind, and may have been forced into service as well, while Barukaza Workshop Scarabs use unstable plasma generators that quickly kill the Lekgolo comprising their control systems. During the early months of their campaign on the Ark, the Banished did not typically employ Kig-Yar mercenaries. However, Chieftain Minas led a strike force that included Kig-Yar on a mission to the abandoned Forerunner Dreadnought in the summer of 2559. The group has also hired Kig-Yar pirates dubbed "Freebooters" and Skirmishers during the Installation 07 conflict.

Personnel
For a full list of personnel in the Banished, see here Due to the circumstances of their founding, the Banished are largely hesitant to engage in the inter-species conflicts that earmarked the final days of the Covenant, with Atriox caring little for the wider war between the Jiralhanae clans and the Sangheili, nor harbouring any particular distaste toward humanity. As such, all are welcome to join the Banished provided they submit to Atriox's will, regardless of species. However, the core of the Banished are made of many Jiralhanae mercenary clans and packs organized into legions, a massive unification achieved by Atriox during the post-Covenant tribalistic warfare that ravaged Doisac following the death of Tartarus.

Although Atriox has no particular-defined rules on which species may or may not join the Banished, he also tends not to interfere in the internal politics of the clans sworn to him, provided they do not interfere with the overall goals of the Banished. As such, the forces personally led by Atriox and Decimus to the Ark had many humans within their ranks, while those forces under the personal command of Escharum showed a more outward distaste toward humanity. Similarly, although the Jiralhanae and Sangheili have a historic rivalry which continues to manifest in the Banished, Atriox has no qualms about working with Sangheili, having recruited the forces of many Sangheili Mercenary groups into the Banished. Several of these individuals attained positions of prestige within the Banished, with Shipmaster Let 'Volir even being granted command of all Banished forces on the Ark by Atriox following his departure, much to the dismay of other Jiralhanae. This willingness to work with criminal elements extends to pirate and mercenary organizations of the Kig-Yar, and even criminal human organizations.

Despite this fairly egalitarian stance, which allowed a few Unggoy such as Briglard to climb the ranks of the Banished's meritocracy, most Unggoy within the Banished retain their thrall/slave nature as they did within the Covenant. This led to a rebellion by grunt forces under Yapyap on the Ark.

The Banished also maintained an alliance with the Lekgolo collective known as "Colony", which allowed the organization to employ the use of many lekgolo forms in their conquests.

Equipment
Having salvaged and repurposed a great deal of Covenant matériel as well as equipment from other sources, the Banished are well equipped with a wide range of military technology. Covenant technology plundered by the Banished is modified to match the aesthetic tastes of its new masters, including an overt preference for layered armor plating, spikes, and sharp angles contrasted with the smooth curves and surfaces favored by the Covenant. The Banished additionally have the capabilities to manufacture their own weaponry, utilising gravitic-catapults in their spike weapons. How the Banished have managed to make such improvements in as short a time as they have continues to baffle UNSC technicians. This industrial expertise also extends to starships of their own design, such as the Banished dreadnought. The Banished are also known to use their own variant of UAV to repair their outposts during the Second Ark Conflict. The Banished are capable of using their own portable shield, which is hexagonal-shaped with trapezoids making up the shielding and be active or not active at the user's request.

Armor
All forces under the command of Atriox and Decimus during the Second Ark Conflict, including the personnel from the Enduring Conviction and the Clan of the Long Shields, were equipped with official Banished crimson and gray colored armor. These include Jiralhanae power armor, Sangheili combat harnesses and Unggoy combat harnesses. Additionally, the Banished employ specialist Jiralhanae soldiers known as Jump-pack Jiralhanae, who are equipped with jump pack propulsion systems. Many of the Sangheili and Jiralhanae in the Banished's ranks lack energy shielding. Many affiliated mercenary clans however, including those during the Zeta Halo conflict, typically reused standard former Covenant armor that had been salvaged and the usage of official Banished armor was limited to higher ranks.

Weaponry
Weapons used by the organization include the Type-1 energy sword, Type-2 gravity hammer, Plasma gloves, Mangler, Type-25 Spiker, Bloodfuel rifle, Skewer, Ravager, Shock rifle, Stalker rifle, Scrap Cannon, Type-51 Carbine, Type-25 Brute shot, Type-25 Brute plasma rifle, Type-25 plasma pistol, , Type-33 fuel rod gun, Disruptor, Type-1 plasma grenade, Type-2 spike grenade, Dynamo grenade, and a custom forged gravity mace called Chainbreaker used by Atriox. The Banished have no taboo against human weapons, and in the Zeta Halo conflict, they also used UNSC weapons such as the CQS48 Bulldog, M41 SPNKR, among others.

Vehicles
The vehicles at their disposal include the Gydrozka Workshop Blisterback mobile missile battery, Klavbrig Workshop Shroud aerial stealth vehicle, Eklon'Dal Workshop Marauder tank, Trespasser sky raider, Griever fighter-bomber, Gravemakers, war-skiffs, and Reaver anti-aircraft walker. The spike turret is used for static defense. They also field the Goblin, Methane Wagon, Klavrig Workshop Skitterer, Chopper, Spirit, Banshee, Wraith, Locust, Ghost, Scarab, Phantom and Eklon'Dal Workshop Lich, all of which depart from typical Covenant aesthetics. The Banished also make use of Type-52 Prowlers.

Ships
They have at least one, the Enduring Conviction as the flagship and once the largest Banished capital ship per ONI, at least five s, and at one point captured the Elegy's Lament. Their ships have the ability to deploy bases for ground combat, such as Banished outposts.

The Banished during their operations on the Ark also used salvaged wreckage from Truth's fleet that was left on the Ark. However, the loss of the Enduring Conviction left them unable to perform the kind of orbital bombardment that the was capable of with her MAC gun.

By October 2559, after absorbing three other Jiralhanae legions, the Banished in the Milky Way have a formidable fleet including at least one former massive Covenant supercarrier, at least one intrusion corvette, several destroyers, and several dreadnought-class warships which were modified from the hulls of Covenant ships, including Ghost of Gbraakon, by the time of the Battle over Installation 07 in December 2559. Dreadnoughts in particular can deploy modular Banished bases to the ground.

Symbols
The emblem of the Banished, known as the Mark of Atriox, is modeled after the appearance of Atriox's gravity mace, Chainbreaker, when viewed from a top-down perspective. Additional symbols can also be found both within and upon Banished structures.

Gameplay
The Banished are one of the two playable factions in Halo Wars 2. Atriox, Decimus, Let 'Volir, Colony, Yapyap, Ripa 'Moramee, Pavium, and Voridus are their playable Leaders.
