Ser Loras Tyrell, the heir to Highgarden, is a popular tourney knight and ranks as one of the most skilled knights in Westeros. He was the lover of Renly Baratheon and supported his claim to the Iron Throne as commander of his Kingsguard. After Renly is murdered and believing Stannis Baratheon to be responsible, Loras has sworn vengeance, and has joined forces with King Tommen and Tywin Lannister in the War of the Five Kings.
Ser Loras Tyrell is the son of Lady Alerie Hightower and Lord Mace Tyrell, the Lord Paramount of the Reach and Warden of the South. The Reach is one of the constituent regions of the Seven Kingdoms and House Tyrell is one of the Great Houses of the realm. Loras was raised in privilege in the family seat and regional capital of Highgarden. Loras is the heir to Highgarden and the Tyrell lands and titles, and this status, along with his skills and good looks, makes him possibly the most sought-after bachelor in all of Westeros
Loras is a skilled knight famed for his many tournament victories and his good looks, which make him popular with the smallfolk and with young women in particular. Loras is one of the few knights who has on rare occasion managed to defeat the formidable Jaime Lannister in a joust. He is commonly known as the "Knight of the Flowers", as a rose is the sigil of House Tyrell and he thus wears armor elaborately engraved with flowers.
Loras is the former squire of Lord Renly Baratheon and remains Renly's close friend and lover. When the series begins Loras is in King's Landing primarily to compete in tourneys and attend court.
Ser Loras takes part in the Hand's tournament, riding against Ser Gregor Clegane. He charms the common people by giving a rose to Sansa Stark, but at the same time, he also exchanges a look with his lover, Renly Baratheon. Loras uses a mare who is in heat to upset and confuse Gregor's mount, as Gregor is known to favor unruly stallions, making it easier to unseat him. Gregor, furious, decapitates his own horse with a sword, and then attacks Loras. Gregor's brother, Sandor, intervenes and saves Loras' life. Even though there is supposed to be one more round with Loras jousting against the Hound to determine a tournament winner, Loras proclaims Sandor the champion, to the approval of the crowds. When Loras raises Sandor's arm declaring him the winner, Sandor looks somewhat lost, as he is not used to the adoration and approval of the public that Ser Loras takes for granted.
Loras shaves Renly's chest in his chamber. Renly comments about how much Loras' armor must have cost his father. They discuss the succession and Loras suggests that Renly should claim the Iron Throne himself should anything happen to King Robert. Renly points out that he is fourth in line to the throne, behind his nephews Joffrey and Tommen and his brother Stannis. Loras dismisses them, saying that Joffrey is a monster, Tommen is too young and Stannis has all the charisma of a lobster. Loras suggests that the common people would support Renly, who is more widely known and popular. Loras suggests that his family would support and finance Renly's claim. Renly remains dubious.
When Catelyn Stark arrives in King's Landing with news of the attempt on Bran's life by the man with a knife, Littlefinger identifies it as his own knife which he lost to Tyrion Lannister on a bet that Loras would defeat Jaime Lannister in a joust which is why Catelyn takes Tyrion prisoner. When confronted with this Tyrion denies it saying he always bets on Jaime to win so he would never have bet on Loras against him.
After Robert Baratheon is wounded and is expected not to live, Renly approaches Eddard Stark offering men so they can seize Joffrey before Cersei can consolidate her power, but Eddard chooses not to act while Robert still lives. The next day, he learns that Renly and Loras have fled the city with their loyal retainers, and were last seen riding south. Tywin Lannister learns that Renly has claimed the Iron Throne, as Loras had urged Renly to do.
Renly declares himself King of Westeros with the support of House Tyrell. He gathers an army of over 100,000 men from across the Reach and the Stormlands. He solidifies his alliance by marrying Loras's sister Margaery Tyrell, the only daughter of Mace Tyrell. He camps his army near Storm's End and throws a tournament for his men. Renly and his new Queen watch from a wooden dais. Margaery stands and cheers Loras as he disarms his opponent. His rival manages to step under a swing of his great axe and knock him off his feet. Loras yields when his opponent lifts his visor and holds a knife close to his face.
Renly congratulates the combatants as they stand and calls the winner forward. He commands them to stand and remove their helm. The crowd are shocked when the fighter is revealed to be a woman; Brienne of Tarth. Renly tells her that she is everything that her father promised. Margaery says that Loras fought valiantly and Renly agrees with her. He names Brienne champion and offers to grant anything that she requests. Brienne asks to join his Kingsguard, and he accepts. Loras is not happy about her appointment to the Kingsguard.
A Baratheon Guard announces the arrival Catelyn Stark. She exchanges greetings with Renly and he promises justice for the execution of Ned Stark. Loras interrupts to ask if Robb has marched against Tywin Lannister yet. Catelyn denies knowing Robb's strategy and says that she would not divulge it to them if she did. Loras says that Robb should have attended rather than sending his mother. Catelyn retorts that Robb is fighting a war rather than playing at one. Renly laughs off the barb and invites Catelyn to walk with him.
Renly and Loras kiss passionately inside Renly's tent. Renly undresses his lover and notes his badly bruised chest before kissing the marks. Loras stops him and complains about Brienne's appointment to the Kingsguard being a further humiliation after she bested him in the tournament. Renly cites Brienne's devotion and then realizes that Loras is jealous. Loras denies jealousy, mocking her as "Brienne the Beauty". Renly begins to undo Loras's britches, saying that he will make it up to him.
Loras stops him and says that he must devote his attentions to another Tyrell that night. He reminds Renly of his responsibilities to their alliance and warns him that his vassals are gossiping about his bride still being a virgin two weeks after their marriage. Renly is disbelieving of Margaery's virginity and Loras says that she is still officially a virgin before going to fetch her. Renly is unable to perform with Margaery and she reveals that she is fully aware of his relationship with Loras. She offers to involve her brother next time, to get Renly "started", and reminds Renly of the importance of fathering an heir.
Petyr Baelish arrives at the camp and offers to open the gates of King's Landing to Renly. Loras walks Margaery through the camp and leaves her at Renly's tent where Petyr is waiting for her. Petyr reveals his knowledge of Renly and Loras's sexuality but Margaery is not intimidated and asserts her loyalty to Renly.
Renly meets his older brother Stannis Baratheon on the coast of the Stormlands to parley. Stannis is accompanied by Melisandre, Davos and several guards. Renly brings Catelyn, Brienne and Loras along with his own guards. Stannis believes he supersedes Renly's claim as the older brother. They are unable to reach a compromise and Renly maintains his position that he would be a better ruler than Stannis. Stannis wheels his horse and rides away as Melisandre warns Renly to look to his sins because "The night is dark and full of terrors." Renly asks if his companions can believe that he loved Stannis once as he leads them away.
Renly is assassinated by a Shadow brought into the world by Melisandre just after agreeing to an alliance with House Stark. Brienne cries out causing two other members of his Kingsguard, Ser Robar Royce and Ser Emmon Cuy to rush in and they find Brienne over the body of Renly, covered in his blood. She is mistakenly blamed for his death must kill them in self-defense before fleeing the camp with Catelyn.
Loras stands vigil for his lover and king in the command tent. Margaery paces anxiously behind her brother. She tells Loras that they need to return home but he does not answer. Lord Petyr “Littlefinger” Baelish enters and greets them. Loras immediately orders him out of the tent. Littlefinger warns them that Stannis is an hour away and that when he arrives Renly’s bannermen will join his cause. He says that their companions will fight for the privilege of selling them to King Stannis. Loras stands and draws his sword and asks if Littlefinger is seeking the same privilege for himself. Petyr points out that he has come to warn them instead of going to Stannis. Margaery pushes her brother’s blade away from Littlefinger and warns him that they have no time.
Loras tells Margaery to ride back to Highgarden and says that he will not run from Stannis. Margaery says that Brienne killed Renly and Loras says that neither of them really believes that. He asks her who stood to gain the most from killing Renly and Littlefinger answers “Stannis.” Loras promises to avenge Renly by killing Stannis. Margaery says that they cannot stay. Loras tearfully returns to Renly’s side and asserts that he would have been a good and true king. Littlefinger asks Loras what he most desires and learns that it is revenge. He says that he has always found revenge to be a pure motivation but warns Loras that he will not have a chance to kill Stannis if he stays. Littlefinger cautions Loras to be smart if he wants justice. Margaery tells her brother that he cannot avenge Renly from the grave. She begs him to bring their horses as she strokes his hair. He rises from Renly’s deathbed and goes to carry out her request.
Before they leave, Loras grieves for Renly's death and expresses regret at having persuaded him to try and claim the throne even though he was behind Stannis, which led to Renly's murder. He admits to Margaery that he loved Renly and she comforts him.
Before the Battle of Oxcross two Lannister sentries are debating who is the greatest swordsman in Westeros. They bring up Ser Gregor Clegane and Ser Jaime Lannister, but when one of them offers Loras Tyrell as a possibility, the other says that Loras Tyrell is not a great swordsman, as he has been stabbing Renly for years and Renly isn't dead.
Petyr obtains authorization from Lord Tywin Lannister to arrange an alliance with House Tyrell. Loras dons Renly's armor to fight alongside House Lannister in the Battle of the Blackwater. His forces arrive as Stannis is assaulting the Mud Gate and their cavalry charge routs Stannis' men. Loras accompanies Tywin to the throne room to announce the victory, and is seen dressed in Renly's armor removing his helm.
Those who played a key role in securing Joffrey's victory are summoned to the Throne room to receive the King's gratitude, and a reward of their choosing. Loras requests that Houses Tyrell and Baratheon be merged via marriage between his sister Margaery Tyrell and Joffrey, to which Joffrey consents, after being "persuaded" by the small council that his engagement to Sansa Stark is no longer necessary or desirable.
Loras and Margaery host Joffrey and Cersei for supper, where they discuss adapting to life in King's Landing. When Cersei criticizes Margaery's recent goodwill visit to Flea Bottom, Loras waxes poetic about his sister's charitable work in the Reach. Joffrey seems placated by Loras' words; Cersei is not.
Some days later, Margaery has Loras call on and escort Lady Sansa to a meeting with her and their grandmother, the Lady Olenna. During their walk, Sansa tries to remind Loras of their first meeting at the Hand's Tourney many months before. Although Loras has clearly forgotten about it, he plays along to avoid insulting her. He takes his leave when Margaery meets them in the gardens. A few moments later, Olenna reminds Margaery and Sansa that "Loras is young and very good at knocking men off horses with a stick. But that does not make him wise."
Realizing that Petyr Baelish is closing in on Sansa and that she, as the only heir of House Stark should her brother Robb lose the war, is the key to the North, Olenna directs Margaery to offer Loras' hand in marriage to Sansa.
Apparently willing to go along with the plan, Loras invites Sansa to watch him spar, although out of earshot he laments that he doesn't have a real challenge. One of his new squires, Olyvar, states that he would like to see Loras spar with a worthy opponent. Away from prying eyes, Loras and Olyvar have an extended sexual encounter. Loras asks how Olyvar realized that he preferred male company as even his intended bride has no idea of his proclivities. Olyvar assures him that the situation is actually more common than is typically realized.
Loras and Sansa spend more time together in the following weeks. Loras admits he's always wanted a big wedding with lots of guests, fancy food and a good tournament, though he only seems to remember that there will be a bride when Sansa gives him an expectant look. Sansa expresses her happiness and looks forward to moving to Highgarden. On this, Loras agrees with her, saying that King's Landing is "the most terrible place there is".
Loras, as a person of rank in the Red Keep, later attends Sansa's wedding to Tyrion Lannister in the Great Sept of Baelor with his sister and grandmother. During the wedding feast, Olenna irritates him by reminding him that his sister is soon to be his stepdaughter-in-law and he storms out. Tyrion later sees him looking down from the upper gallery and raises his glass in sympathy. Loras sees Cersei miserably regarding Blackwater Bay out a window and tries to make small talk, but she rudely brushes him off.
Loras's grandmother, Olenna Tyrell congratulates Brienne of Tarth for besting her grandson during the melee at King Renly's camp, describing him as a "silly little boy".
Loras attends the wedding of his sister and King Joffrey; enjoying a brief flirtation with Oberyn Martell, before being confronted by Jaime Lannister over his engagement to Cersei. Jaime attempts to intimidate Loras into calling off the wedding, warning him that Cersei will murder him in his sleep, along with any children they may conceive together. Despite having no affection whatsoever for Cersei, Loras retorts to Jaime that he will never be able to marry Cersei either, clearly aware of Jaime and Cersei's relationship. He walks off, leaving Jaime nonplussed.
During the re-enactment of the War of the Five Kings by dwarves in full costume, Loras looks on as the one dressed as Stannis (riding Melisandre) attacks another one dressed as Renly (riding a crude naked depiction of Loras). Distraught and disgusted, Loras leaves his seat on the dais altogether and doesn't return.
Loras later attends the coronation of Tommen Baratheon. Cersei later agrees to marry Loras a fortnight after Tommen's wedding to Margaery, a month after the coronation. Along with his sister and father, Loras is later present at the trial of Tyrion Lannister.
During Tywin's funeral, Loras attempts to approach Cersei, going on and on about how fearsome Tywin was, but Cersei practically ignores him and stalks off. At night, Loras is cuddling with Olyvar post coitus, discussing the possibility of visiting Dorne or anywhere far away from King's Landing, when Margaery walks in. She admonishes Loras for making them late for supper with King Tommen. After Olyvar has taken his leave Margaery urges her brother to be more discreet especially in the Red Keep. Loras no longer cares as he knows everybody is whispering about him anyway. Loras is puzzled by Margaery's relaxed attitude, as Tywin's death means Cersei won't be forced to marry Loras and be sent off with him to Highgarden, which means Margaery will have to contend with her mother-in-law at the capital. Margaery implies that may not be the case.
Loras is present during the wedding ceremony of Tommen Baratheon and his sister Margaery.
During a sparring session, Loras is seized by Lancel Lannister and the Faith Militant. Lancel tells Loras that he has "broken the Laws of Gods and Men". Margaery deduces that Loras's arrest was partly Cersei's doing in order to undermine the new queen. Tommen later attempts to have Loras released by confronting his mother then trying to speak to the High Sparrow, but neither endeavor bears any fruit, prompting Margaery to write at once to Olenna.
During his holy inquest by the Faith, a somewhat disheveled Loras is asked how he answers to the buggery allegations. Loras of course denies he was ever Renly's lover, and assures the High Sparrow they were merely best friends, Margaery, when asked to testify backs her brother up. The High Sparrow then calls forth a surprise witness: Olyvar, who quickly exposes the lies of both Tyrell siblings. This leads to Margaery's arrest for perjury and a full trial before the gods for Loras.
Margaery is permitted to access Loras in prison. He is worn out and beaten down by the Faith Militant's treatment of him. Margaery tries to get him to stand up for himself and calls him the future of the Tyrells, but Loras states that he just wants his imprisonment to end and wants to acquiesce to their demands. Loras begins to sob uncontrollably, and his sister hugs him close to her chest.
A shivering Loras is taken from his cell by some Faith Militant Brothers. Later Loras with his head shaved is brought before the High Sparrow and the assembled nobles in Baelor's great sept. Loras states that a trial won't be necessary, because he wishes to plead guilty to all accusations laid against him. To show his newfound devotion to the faith, the former knight agrees to join the Faith Militant and renounce his inheritance. After the seven pointed star has been carved into his forehead by Brother Lancel and others, Loras is comforted by his sister and father. When Cersei doesn't show up to her own trial, Margaery realizes that something is seriously amiss. She attempts to lead her father and brother to safety, but the Sparrows prevent this. Loras tragically dies alongside his family when Cersei burns the Great Sept to the ground.
The handsome young Ser Loras was the secret lover of Renly Baratheon, for whom he served as Kingsguard. After Renly's murder, Loras unknowingly took a spy for Littlefinger, Olyvar, as his lover, though Loras was obligated to marry Cersei Lannister. Cersei engineered her fiancé's arrest by the Faith Militant to undermine the Tyrell's influence in Kings Landing. The arrest of the heir of Highgarden also ansnared his sister the queen, whi was imprisoned for perjuring herself to protect him. Physically and emotionally broken in prison, Loras led guilty to the Faith's charges against him and agreed to renounce the Tyrell name. He was among those killed when the Sept of Baelor exploded.
