"Pity, I was having so much fun."
―Tir-D-yar following the Battle for Doisac

Tir-D-yar (born 26th September 2499) was a Kig-Yar sniper during the 9th Age of Reclamation. Afterwards he became an assassin and leader. He is the primary antagonist of the Stel-verse, alongside his many lieutenants and commander Lady Sintharia. Tir is well known as the only Kig-Yar to conquer an entire planet (Reach). He is the son of 'Jackal' Myr-D-yar and the 'Skirmisher' Bor-D-yar.


Early Life

Tir was born on Eayn to a Female Pirate Myr-D-yar. After he was hatched, he was catered by a friend of the family. He grew on his Mother's milk and developed his attributes. Being raised in a pirate family which was part of a Pirate Clan, Tir was raised from infancy to be ruthless, cunning and bursting with agility. Tir never knew his father, which lead to Tir's opinions on only caring for himself as his Father never cared for him. Approximatly thirty five years later, Tir would learn the identity of his father was forever shocked by the news. When Tir was brought into the education system, he thrived. This was mainly due to him blackmailing the more intellegent Students into Tutoring him. When Tir was fifteen, he first seen his first love, Ryi-B-for.

Tir immediatly entered a relationship with Ryi, however when another Male impressed Ryi, she left Tir on the spot. The news was devestating to Tir; the events lead to his cruelty to others and his hatred of others (Male or Female). Tir quickly recovered from this event and began to torture those who irratated him or despised him. His mother was overjoyous of what a mastermind criminal Tir had become. By the end of his education, Tir was the most feared of the Kig-Yar in the school. Even the mighty Skirmishers feared him. However, Tir's reign of terror ended when he was forced to join the Covenant Military.

Battle of Harvest

Tir-D-yar: "I miss the Skirmishers, I enjoy their company."
Par-K-opar: "What you really loved was their brutality, wasn't it?"
Of course, I shake in excitment when I see them tear through the flesh of the humans. The crimson, splattering blood is glorious.: "Yeah, I suppose your right."

Battle of Reach

"His head just 'rolled in the wind' if I had to say anything."
―Tir after Stel killed a SPARTAN-III

Battle of Hope

Almost immediatley after Tir, Stel 'Vadam, Ral 'Daman, Bur-T-der and very few other soldiers survived the battle of Reach (more specifically, the battle of Terrador), Tir was put in a new squad along with two of his fellow snipers. Tir was sent to the UNSC planet Hope. While being sent to his mission, his Phantom Dropship was destroyed, with his squad barely escaping. Tir hid in nearby bushes and looked on as the UNSC fired upon his exposed squad. He and two other Kig-Yar managed to escape and eventually found their way to a town destroyed by a recent covenant invasion. Tir had to pretend to be a lifeless corpse[1] numerous times as he tried to find a way off the planet, wishing to have remained on Terrador. He eventually discovered a Phantom which had an injured pilot. Tir threatened the Sangheili to fly the Phantom off the planet and back to Eayn. However, as the Phantom reached space, the pilot turned the Phantom towards a nearby ship. Tir slain the pilot for his treachury. After failing to correctly fly the Phantom, Tir was discovered by a nearby Covenant Battlecruiser. He was sent on a phantom heading for High Charity where he would be punished by the Council for abandoning the battle. As he reached High Charity, Tir killed the pilot and quickly escaped the ship, retreating back to the Kig-Yar section of the city.

Invasion of High Charity

"What? Did you honestly believe that I would allow Sangheili filfth on my ship? Enjoy your descent; the flood need a meal."
―Tir-D-yar to his Sangheili commander at the end of High Charity's invasion

The Battle for Doisac

Main articles: Halo: Vendetta and Halo: Sangheili Brothers


The Jiralhanae Fleet Master Beracus called for a meeting with Tir, knowing him well. He ordered Tir to assassinate Stel 'Vadam, Ral 'Daman, Rochelle-108 and Doug-103, for a large some of money. Tir began by scrambling the systems of Ryil 'Drean's Banshee before it went into service. Ryil's death proved to Tir that Stel is momentarily weakened by the death of a friend. Tir brought his brother to help the group of three to kill them. Tir's brother was quickly slain by Rochelle-108 after he killed a Marine standing infront of Doug-103. Later, during a stormy night, Tir ordered his assassin Yer to kill them while they slept. However, Yer's position was revealed by the illuminating light of a crashed Phantom. Yer revealed Tir's intentions, and Stel and his group went on the hunt to kill. Tir spoke to Beracus onboard the Jiralhanae base The Eye, refusing his offer. As Tir and Bur began to leave Doisac, he was cornered by Stel and his group.

Tir and Bur

Tir with Bur before Bur's death.

When Stel encountered Bur and Tir attempting to escape Doisac, he challenged Tir to a duel. Bur then whispered to Tir to run away while he could. Seeing it as a benefit for himself, Tir gave Bur a Plasma Charge, which would later contribute to the death of Rochelle-108. Bur slain Rochelle but was decapitated by Stel. Returning to the sluaghter, Tir laughed as Stel didn't realise the difference.

Sangheili Brothers

The Following Paragraph will be explained throughout the course of Halo: Sangheili Brothers.

It is only known that Tir recruited two more Kig-Yar into his services at this point.

Return to Reach

Main article: RP:Reach
Tir hacking

Tir kills a human transient by causing his shield to 'half' deactivate and electrocuting his victim.

"You will not escape me that easily, Stel 'Vadam. I will have my revenge!"
―Tir after Rola is freed.

Some time after the events of the Battle for Doisac's conclusion, Tir retreated to the damaged planet of Reach. From there, he and his two fellow assassins began to enlist eager Kig-yar into Tir's service. Tir found that these candicates didn't have the will to put their life at risk for Tir, so the majority of them were personally slain by Tir[2]. Shortly before the arrival of the Relentless Massacre on Reach, Tir began scheming against the Jiralhanae in the city of Terrador. However, his plans against the Jiralhanae were halted when the Relentless Massacre arrived on Reach on outskirts of Terrador. Stel 'Vadam and Ral 'Daman and a group of Sangheili began to scout the city. Tir then thought that the Sangheili could forward and accelerate his plans.

Jackal Darkness

Tir on Reach preparing to torture Rola 'Vadam.

Stel did infact accelerate his plans, when he was forced to deal with Stranded humans on Terrador. Tir himself descends down to the underground caverns of Terrador. Tir slaughtered the Human infestation, while he searched for his enemie's brother- Rola 'Vadam. Upon penetrating Rola's defences, Tir began to tortue Rola. During the process, a commander of the Jiralhanae on Terrador arrived at the seen. Shielding himself from the Brute; Tir continued to deal with Rola. Secretly, he inserted an Electrical Shock transmitter onto Rola's thigh. Rola actually never discovered it and it has since remained. When Stel 'Vadam entered the room, Tir watched as he slain the Jiralhanae. Tir retreated back to his ship along with his Kig-Yar companions. Upon retreat, Tir dropped a bomb on the station, causing the cavern to flood. Tir's plan proved to be much to his advantage as the water flooded into the Relentless Massacre and flooded the lower levels of Terrador.

After the events, the Relentless Massacre along with Stel 'Vadam left Reach. Tir used this advantage to conquer the Stranded Humans. In his campaign, he and his Aspirants eliminated all Jiralhanae presence on Terrador. Without their leader, the Jiralhanae descended into chaos. Once he had taken the last city on Reach, Tir quickly became the master of Reach.

The Eayn Civil War

Main article: Halo: Covert Ops
"Together we will forge a grand alliance and wreak havoc upon our enemies."
―Lady Sintharia when some Nartol join Tir-D-yar's forces.

Tir returned to Eayn after his conquest. However, he only saw war. Some Kig-Yar actually still remained loyal to the Great Journey. Two sides conflicted for conquest of Eayn. Tir quickly used this to his advantage. While the Seperatist Kig-Yar wanted for Eayn to be free and not under one affiliation like it had been for centuries, Tir simply wanted to gain control over most of the Kig-Yar clans. That was, until Stel 'Vadam and Task Force 343 arrived...

Mid-way through the battle of Eayn, Operation: DECIMATION is enacted and thousands of Nartol hear tales of his actions and his lands (Reach, part of Te and a large portion of Eayn) and their leader Lady Sintharia allied with Tir.

The Battle of Terrador begins

Its elementary, my dear Yormus

Main article: Halo: Obsidian Conflict

Tir was later found on the Karidan homeworld about 5 years later, proving he survived the devastating events of Halo: Covert Ops. Why he is seen with the Jiralhanae Yormus is unknown, but his activites during the event will be explained in Halo: Obsidian Conflict. As Yormus continued to fail him, Tir-D-yar enlisted his lieutenant Lady Sintharia to assist Yormus in his tasks.

The Fall of Yormus

Yormus: "Tir, please... help me. That is an order!"
Tir-D-yar: "I'm afraid not, Yormus. Jaraputo may still be strongly held by the filfthy natives, but your reign of terror is over. Stel, I wish you good luck on your duel, I will not kill you at this point but remember, the next time we meet, it will be as enemies. Sintharia, deal with this interruption."
―Yormus begging for Tir's help shortly before his death.

With the Jiralhanae recruitment centers and the Military bases on Jaraputo destroyed by Stel 'Vadam, and the 'secret' headquarters deployed to teach the Karidans of the Great Journey under siege by the Sangheili, Yormus' luck was running out. Tir and Sintharia realised this and tried to salvage whatever they could before returning to Reach. Upon entering a Karidan intellegence facility, Sintharia discovered that the Karidans had been spying on dozens of habitable planets. The list appeared, revealing all the Karidan knowledge to them:

  • Sanghelios
  • Earth
  • Jupiter
  • Mars
  • Azather
  • Peonisit
  • Ponosofom
  • Saturn
  • Te
  • Balaho
  • Doisac
  • Belehum
  • Lerponosa

Tir ordered Sintharia to hack the system and download all the data onto a memory file his removed from his person. Sintharia worked on it while Tir assassinated Tornopus, Yormus' left hand. Tir, undetected during the assassinaton, walked out the front door quite literally an ally of the Covenant Loyalists. He then noticed that Yormus' sucessor, Ledipus, was on Jaraputo at the time. Tir returned to Sintharia, who had done as she was told. The two and their forces began to leave Jaraputo. Along the way, Doug-103 and a female Sangheili had began slaughtering the Karidan security guards. Tir and Sintharia sent two Skirmishers down to distract the enemy while they fled. As they reached the central war room, Yormus called for help. Tir noticed that Yormus was under attack by Stel 'Vadam and Rola 'Vadam. Tir denied the command, and Rola 'Vadam swung himself at Sintharia. Sintharia's royal guards dueled with Rola, while Tir ran up the stairs. The frightened Jiralhanae advisors were slain by misses in the duel between Rola and the Guards. Stel and Yormus' duel escalated through the incomplete sections of the building, slowly ascending towards the roof. Rola slain one of the guards, who collapsed hitting a safety switch. The switch deactivated a robotic arm which was holding a piece of metal keeping a thick group of razor thin wires in place. The metal fell, knocking Yormus' left hand.

Tir then came face to face with Ledipus, and the two clashed with their weapons. Tir's agility and reflexes clearly outmatched the veteran Jiralhanae commander. Ledipus managed to kick an energy blade out of Tir's hand and he chucked a plasma charge inbetween the two. He fled with Tir in hot persuit. Ledipus chucked a Spiker in Stel's direction, which briefly blinded Stel's left eye. Yormus tried to flee with Ledipus, but Stel sliced through his back armour with one quick swing, prompting Yormus to face his foe. Tir headbutted Ledipus, knocking him to the ground. Tir was then knocked out the way by a swing from one of Yormus' Gravity Maces. Standing up, Tir pulled out his Plasma Pistol and shot an overcharged shot straight into Ledipus' back. Limping, Ledipus boarded a Phantom which rose into the air. The Phantom fired upon Stel, who narrowly dodged the attacks. As Yormus tried to perform a headcrack Stel couldn't avoid, Tir chucked a Plasma Charge at Yormus, stunning him and accidently causing him to smash his chest armour with the mace. Stel then proceeded to stab Yormus' gut, and chucked him off the edge of the roof. Yormus landed on the wires which had been dropped before, and suffocated. Giving a slight nod to Stel, Tir boarded his ship with Sintharia and the surviving Royal Guard and left Jaraputo. His next target was the temporary leader of the Covenant Loyalist military - Ledipus.

The Hunt for Ledipus

The End of the Battle of Terrador

Pol-D-yar: "Any last words, brother?"
Tir-D-yar: "You've just said you own."
―Pol and Tir before the duel

Tir returned to Reach after losing Ledipus on Te. Reach's honorable defenders were pushing back the Kig-Yar Loyalists. Tir's brother Pol-D-yar enlisted the help of seven Special Operations Kig-Yar to assassinate Tir and Lady Sintharia. However, as Pol entered the room, Tir wasn't suprised. Tir had prepared by calling in two of Sintharia's Royal Guards. The seven Kig-Yar engaged in combat with the guards, the seven just managing to not die against the Nartol attacks. Pol and Tir entered a brief moment of brotherly hatred and attacked eachover. Tir utilized his two Energy Daggers with great agility. Pol had only learned Sangheilian Swordfighting and not the vast and complicated strikes of the Kig-Yar melee. In the fight, two of the Special Operation Kig-Yar were killed by missed hits between the brothers. Pol began to mock Tir and his ability. Tir shrugged it off by reminding Pol of how he could not help their mother and that Pol may aswell kill himself rather than Tir.

"You have the will to live and the rage needed to fight. You are also willing to kill me because our mother was killed ten years ago. You would of made a brilliant addition to my forces."
―Tir-D-yar comments on Pol's ability

Tir deployed two Plasma Charges and stunned Pol; Pol fell off the balcony onto the floor below. In hot pursuit, Tir leapt down to finish his wounded brother. Pol regained his senses in time to save his hide. The Royal Guards suddenly retreated to the confusion of the Kig-Yar. A few seconds later, Lady Sintharia appeared and began slaughtering the avian aliens. Sintharia near instantly blew a hole in one of the assassins with a blow from her Nartillian Plasma Hammer. A gunfight then ensued as Sintharia pulled out her Plasma Rifle and began to fire upon the gun-wielding enemies. Pol sliced the skin off the top of Tir's left arm. Tir leapt onto a metal transporter heading for Mount Koro on the north side of Terrador. Pol followed on the next one, firing his Plasma Pistol in Tir's direction. The assassins combined the power of their shockwave guns and blasted Sintharia out of the building. Pol overcharged a shot at Tir's metal transporter's support. Tir landed on the roof of an old human mining facility rejuvinated by the Kig-Yar. Tir threw a plasma grenade at Pol's machine. Tir and Pol then continued fighting through the facility, heading deeper into the mine. Sintharia feigned death as the Kig-Yar approached her. The Kig-Yar then began to check if she was dead. She rose up, revealing a plasma grenade where she lay. Sintharia quickly retreated around a corner as the Kig-Yar were destroyed by the explosion. Tir and Pol then fought across the holotracks. Tir jumped, grabbing hold of the side of the track. Pol prepared to end his brother's life, however Tir leapt up and covered his brother with his cloak. Pol was kncoked to the ground and beat severly (as a last chance of surrender). Pol refused and continued to fight his brother.

"Please... brother."
―Pol-D-yar's last words

Tir was knocked down and then tripped up Pol. Pol tossed his last plasma grenade, which missed and destroyed the holotrack's controls. Tir retreated while firing his pistol. Pol leapt for the normal ground, but the holotrack deactivated. He just managed to make it and continued fighting Tir. The ground underneath Pol began to crack because of the explosion. Tir then gained the upper hand and sliced Pol numerous times. Pol noticed the ground and began to limp towards Tir. Tir slashed Pol's throat, causing him to fall to the ground mortally wounded. Pol then pulled out a small bomb he had been concealing the entire fight. Sintharia then entered, took the bomb and deactivated it. Pol attempted to crawl towards the two. In his last breath, Pol pleaded for mercy and reconciliation in his dying moments. Pol said of how he could become a Kig-Yar of legend for coming to his senses before his honorable death. Pol made a final plea before Tir activated a Plasma Charge. The charge near blinded Pol and cracked the rock. The last sight Pol saw was of a pale white image of his brother watching him plummet to his death.

Arrival on Sanghelios

After the events in Obsidian Conflict, Tir abandoned Yormus and he and Lady Sintharia began plotting in Kiju, an underwater city on Reach. After some debate, Tir gladly managed to evade Sangheili fleets and blockades to arrive on the surface of Sanghelios. After The Destined Ones contacted him, Tir came to their base of operations for negotiations.

The End of the Sangheili Civil War

Kin 'Forsom: "We didn't do anything!"
Tir-D-yar: "Didn't you?"
―Kin 'Forsom and the rest of the Destined Council pleading with Tir before their deaths.

After discovering that Sintharia was not guarded when she was arrested, Tir swore revenge and began to investigate who was the cause of it. It did not take long to break into files that shown the army's movements, and the Kig-Yar discovered that it was the Destined Council themselves who redirected the team sent to Sintharia to fight in the Vadam state. As Stel 'Vadam fought against Serka, Tir used the chaos to enter the lair of the Destined Council. Beginning his onslaught, Tir ultimatley killed half of the Council in seconds. By the end, all the Destined Council (Kin 'Forsom, Jik 'Rolam, Fehn 'Kidin, Hur 'Lopam, Rinca 'Vadam, Wird 'Nobom, Serka 'Larkon and several other Council members and guards) were murderred out of revenge. Not soon after, Serka 'Rolam was killed, which lead to the dissolving of the Destined Ones. Tir briefly spoke to Sintharia (who was still in prison), before leaving Sanghelios and going to an undetermined location.

Attack on Eayn

Sintharia's Betrayal

Tir-D-yar: "Sintharia help me hack the wall. I can break through, use this device your people have been building for so long and either escape or use it to strengthen myself."
Lady Sintharia: "No, Tir, I won't allow you to defile my people's work. Have you even considered what me and the Royal Guard would do to anyone who used it?"
―Lady Sintharia cuts off her alliegence to Tir, sealing his fate

Schism's End and Death

"I am the kind of person who would shed blood upon the soil of which his mother is buried, what say you?"
―Tir-D-yar to Lady Sintharia

As the Great Schism began to draw to an end, the Jiralhanae launched one last attempt at conquering Azather and using the device to either allow them to escape or use it as a weapon. The Nartol were more prepared and annihilated half of the invasion fleet before it even deployed troops. After surviving Sintharia's assault, Tir retreated to the Cult of the Black Sea's ruined base Kikonso. He learnt from the Cultists of the true nature of the device, and Tir was even more determined to unlock it's secrets. He began negotiations with the Cult, and gathered a few vials of extremely potent poisons. In order to render himself immune to his deadly weapons, he was forced to inject himself with a small dose. After this the Cultists kept him safe as Tir entered a coma as a result. He had to be injected with nutritional needles for a total of two weeks. When he awoke the Cultists ran a few tests before confirming that Tir was completely immune to the poisonous liquid gas. When thrown, the puddle emmited a just as deadly gas. The liquid would incinerate anything it touched. Tir then often plotted in the building in which his mother died.

It was not long before the Sangheili, specifically Task Force 343, arrived on Azather to assist in fighting the Jiralhanae and Karidan forces. The Jiralhanae were soon forced to retreat south, into the 'desolate lands' defiled by the Cult of the Black Sea. The Cult didn't respond well to this and decimated multiple Jiralhanae outposts. Tir assisted as he wanted to join the Cult. The Karidans soon arrived and due to what can be assumed to be desperation, the Loyalists fought brutally to beat the Cultists back, and managed to stop the assault group, leaving the Cultist facilities open for attack. In one last counter attack, the Cultists, including Tir, fought the Karidans. Task Force 343 had also lead an attack to eliminate the Loyalists just incase they managed to best the Cultists. Rola 'Vadam and Stel 'Vadam both witnessed Tir striking down numerous Jiralhanae. Stel decided to kill him and end the long rivalry. The following night, Cultists reported that the Sangheili were assaulting the base in a blown stealth operation. Tir grabbed his Cultist weaponry and entered the main Cultist building in which his mother had died. Task Force 343 stormed into the room and barricaded the door as the Cultists were in hot pursuit. Tir appeared and activated two Skirmisher wrist shields as he began to unload all of his deadly liquid gas across the room. The Sangheili managed to avoid it, however Tir deactivated his shield briefly and started firing madly, causing some Sangheili to accidentely breathe in the gas as they moved out of the way. Stel tossed a few Plasma Grenades at Tir, causing shrapnel to spread and hitting him in the elbow and scraping the material of his boots. Tir fled, gaining a large head start due to the gas. He knew his end drew near as he witnessed his aircraft being destroyed by a Banshee strike. He could faintly hear 'That was for Ryil you avian demon!', making Tir believe a relative of Ryil 'Drean was the pilot. Tir arrived at the graveyard, and sat down infront of his mother's grave.

Stel 'Vadam: "Tir, throughout both wars I never thought you would show mercy to anyone. Then again, I would not show any mercy to a cold-blooded Kig-yar such as yourself. You are cornered. Give up, and I will let you rot the rest of your life in custody."
Tir-D-yar: "Sintharia escaped, what makes you think I won't?"
Stel 'Vadam: "My brother nearly died when that bitch escaped, believe me I would personally guard your cell until your dying breath."
— Tir and Stel's talk before the final stand.
"Tir, you are very loyal to your cause, but you will not work for the wretched Cult of the Damned to destroy my homeland. You must die for your treachury!"
―Lady Sintharia arriviing at the graveyard

Stel and Rola arrived at the graveyard to kill Tir while the others treated the wounded and fended off the Cultists. After a brief discussion between the two, Lady Sintharia arrived at the graveyard and was offended that Tir was now working for the Cult of the Black Sea. Tir pulled out two Plasma Rifles and immediatley took cover. A three-way battle between Tir, Sintharia and the Vadams had begun. Rola was told to handle Sintharia while Stel would personally take out Tir. However Sintharia proved to be a deadly threat and Stel had to assist Rola in fighting her. After a brief braul, Sintharia hit Rola with the butt of her Energy Pike and launched him through a few gravestones. Tir then emerged from the rubble of his mother's gravestone and grabbed his last vial of the Cultist liquid gas. He got Stel's attention, and poured the liquid onto Rola's face, incinerating it and causing Rola to choke. As Rola died, Stel turned his attention completely off Sintharia and blindly charged at Tir. Stel stopped, however, when Tir entered the gas. Now immune to it, Tir used his advantage to fire upon Stel and managed to shoot his shields off. However Stel fired a shot from his Plasma Pistol and shot a hole in Tir's leg. Tir then fired a Needle Rifle shot into Stel's chest. With both of them kneeling on the floor, both staring in rage, Sintharia used this to her advantage, pushed Stel aside and grabbed Tir with her extra arms and tossed him against a wall and then proceeded to begin her asphyxiation method. Sintharia then grabbed her pike and stabbed Tir in the lung and dropped him. Tir then spoke his final words, "You've done well, Sintharia. The student became the master. I would much rather die now, next to my mother and the corpse of my arch rival's brother, then any other time. Do me one favour, Sintharia, kill Stel for me."

Sintharia responded to this before Tir died, saying that she was always Tir's superior and that she will fulfill his last wish. Tir then died. Sintharia then briefly spoke to Stel, stating that with Tir dead the threat to project now lay with just the Loyalists.

"I had hoped, by now that Tir would be dead. My prediction has came true. We have all lost something to this monster that lies before us. Some, more than others. All that matters now, however is that he is dead now (grabs a torch, and slowly lowers it onto the corpse). Our future should be of glorious battles as we slay the Jiralhanae and spit on them as they defy us. There will be a time for grieving, this much is true. But for now, this is a time for celebration. The Sangheili are safe and well, and the Project is left untouched. In a way, this was a victory worthy of galaxy-wide celebration. The moon sets upon this night, and with it, the dawn of a new day is ushered in. The dawn, of victory."
―Sintharia to Stel after Tir's death.

Being Neutral Evil, Tir is generally cruel, and performs his activities without remorse and lays out every plan before commiting to it (with only one occasion that he hasn't[3]). Tir is cunning, and he is known to be laugh maniacilly upon achieving victory over enemies[4]. The majority of the time, Tir just lays silent, plotting, showing his doesn't like must conversation if not needed. Tir seems to border Chaotic Neautral, relentlessy slaying unworthy initiates[5]. Overall, Tir sees himself as 'in balance', as there is no Good without Evil, there is no calm without wild and their is no judgement without pity, despite the fact he knows he is evil.

Combat Style

"Cheers 'mate'"
―Tir after knocking Doug-103 out[6].

Tir has a basic fighting scheme. Although he rarely partakes in large battle personally, he often does enter combat with what he deems 'less worthy' individuals. Tir is a master of Sangheilian Swordfighting and Kig-Yar blade techniques; it is often believed that he is one of the greatest Kig-Yar melee fighters. He uses a combination of the two to best suit melee combat. However, he usually resorts to ranged weaponry against his enemies. Tir is considered to be a Kig-Yar of advanced accuracy.

In combat, Tir usually begins with his allies fighting infront and behind him, keeping his enemies occupied while he open fires. As his enemies number is reduced, he will change his weapon to his plasma pistol (which is always kept somewhere on his body) and open fire into his enemies flesh. He will then proceed to annhilate what little resistance remains by either backstabbing or by overpowering an enemy and repeatably stabbing the victim[7]. In the event that he is cornered, he will rapidly fire his Plasma Pistol at the enemy infront of him and try to make a hastey escape, with his allies covering his retreat.


Tir is a formidable opponent in the arts of Sniper Rifles and melee combat, which he can ensure that he is participating in either. Tir is also very 'jumpy' and will react (and most likely attack/neautrilize) to any additional threats which would backstab/shoot/capture him while his focus is elsewhere. Tir is also cunning, which gives him a large advantage in a fight. He is also incredibly swift and can nearly outrun a SPARTAN-II[8] and easily outrun most Sangheili[9] or even outrun the flight speed of Drones[10], he is seen outrunning an oncoming Drone swarm, which he later kills.


Tir, for the most part, is very unbalanced in terms of whether he thinks he can take down an oncoming enemy. Aswell as this Tir (like all Jackals) is a coward when it comes to fighting a battle which is impossible to win. Now that he is no longer bound by Covenant law (even though he does it even with the covenant's rules[11]) Tir also relies heavily on allied help against more than one person following the events of Vendetta[12] Although he is seen in Halo: Desolation taking on Stel 'Vadam, Ral 'Daman, a vengeance seeking Rola 'Vadam and Doug-103 on his own, in which fight he is victorious. Also, in RP:Reach he is seen leading the invasion of the Jiralhanae district of Terrador on his own.


Tir's only known family is his mother, his brothers and his father:

  • Myr-D-yar, his mother. She was a high ranking member of the Cult of the Black Sea before being killed by Stel 'Vadam on Azather.
  • Kor-D-yar, one of his brothers. He died during the Battle for Doisac and was indirectly responsible for the death of Rochelle-108.
  • Bor-D-yar, Tirs father. His status is unknown.
  • Kol-R-ah, Tir's cousin[13]
  • Pol-D-yar, Tir's brother. He died in the closing days of the Battle of Terrador.[14]
  • Amer-D-yar, Tir's sister. After a traumatic event and the death of Kor-D-yar, she became one of the most infamous murderers on Eayn until being incarcerated in an Asylum. She commited suicide in 2572.
  • Numerouse other unidentified brothers and sisters. Majority of them are deceased[15]


"Hope... is for the weak. It is a fascade for defeat."
―Tir to Ral 'Daman

"I think you know I am not a gentleman, sangheili."
―Tir to Stel

"Risk my life for the sake of others... bah! Next you'll be asking me to save children in the cities on Sanghelios."
―Tir-D-yar during the Battle of Reach

"Sintharia, deal with this... interruption."
―Tir to Lady Sintharia during Halo: Obsidian Conflict

"I will return, pretty soon Stel you will be facing a much deadlier enemy and you will never be able to defeat me."
―Tir at the end of Covert Ops

"I know exactly why I was put in your squad. Because Truth wants a war hero to lead his soldiers to victory. You are no hero, you are a coward like the rest of your race. I will watch as the people you lead into the plains of this god forsaken planet will drench it with their blood. Soon they will learn to despise you as I do, and when you lay dying next to the corpses of your friends and family, you will know exactly who drew the knife through your honor driven body."
―Tir to Stel during the Battle of Reach.

"Did you know that Keflus was not always the maniac, bloodthirsty Jiralhanae he was when you shot him oh so many years ago. Once, he even had a loving family, Sangheili friends and the trust of the Covenant. Look at what you did to him Stel."
―Tir trying to expose a weakness in Stel 'Vadam.

Serka 'Rolam: "Surely the fact that we have managed to remove 65% of the Sanghelios army and convert them into our ranks impresses you, mercanery"
Tir-D-yar: "Hmm, lets compare that to what I've done. I've evaded the Covenant for over 20 years by going AWOL on Harvest and entering Cryo-Genic sleep. I've killed a SPARTAN, who kill hundreds of your kind before going down. I've survived near countless encounters with Stel 'Vadam and his gang of friend slash soldiers. I've conquered Reach and started a four-way war on my homeplanet of Eayn. I have allied with Lady Sintharia, who's forces have ruled the oceans of Azather with an iron grip for millenia. Five of my brothers have died by my hand as they attempted to betray me. I sent my mother to Azather to join the Cult of the Black Sea, which has killed millions of Nartol and thousands of Sangheili and Jiralhanae. Finally, me and my forces combined have killed more Sangheili than you have converted. I admire you passion, but it will take more than that to get my attention."
―Serka 'Rolam attempting to boast his actions to Tir in an attempt to ally with him in 2570.

The Destined Ones Meeting

Lady Sintharia, Kor-Y-er, Tir-D-yar and Yir-T-sor are in Kiju on Reach

Tir-D-yar: As you all know, the recent events on the Karidan Homeworld ended in complete disaster.

Kor-Y-er: The Last time we put our fates in Jiralhanae hands

Tir-D-yar: However, it was not a total loss on our part.

Lady Sintharia reveals a glowing object and places it on a table, it shimmers, revealing a hologram of a planet

Yir-T-sor: What is that?

Lady Sintharia: This is the planet of Sanghelios, population 8.87 billion, 96% of the population, sangheili.

Kor-Y-er: And what is so special about the enemy homeworld?

Tir-D-yar: The fact that the Karidans have been spying on it for about a decade now is quite important, don't you think? Why else would I ally myselves with a Jiralhanae version of us?

Kor nods

Tir-D-yar: The devices have spread across the planet, and I have watched from the Karidan's bases. As Yormus scratched his head in confusion on why his men were dying.

The Hologram deactivates

Tir-D-yar: A rebel group has formed in the Sangheili, called The Destined Ones. They are the key to destroy many Sangheili settlements.

Yir-T-sor: So what should we do? Let them slowly waste away behind the scenes while the Jiralhanae attack up front?

Lady Sintharia: No. If we can get onto Sanghelios, we can ally ourselves with the rebels. Think of the possibilities. The Sangheili will not know who is greeting them or stabbing them in the back, and we will gain a healthy number of cannon fodder.

Tir-D-yar: As Sintharia so delicatley put it, the best option is to use the rebels for our own benefit. We leave for Sanghelios tommoro, and if they don't ally with us, we do this on our own.

Lady Sintharia, Tir and Sintharia's two royal Nartol guards leave the room.
