Daario Naharis was originally a lieutenant in the Second Sons, a sellsword company, before taking over the company and killing his superiors, Mero and Prendahl na Ghezn. He then aligns with Daenerys Targaryen, serving as her advisor and enforcer, eventually becoming her lover. Following their victory in Slaver’s Bay, he is forced to part ways with Daenerys when she sails for Westeros, remaining in Meereen to enforce the Queen’s peace.
Daario is a Tyroshi sellsword, employed as a lieutenant in the Second Sons. He is apparently held in high enough regard by the company’s co-captains, Mero and Prendahl na Ghezn, that they allow him to join them in contract negotiations and discussions of the company’s future.
According to Daario, his mother was a prostitute, and he comes from low beginnings. At the age of 12, Daario was sold by his mother to a slave master from Tolos due to her declining income, alcoholism and his aggressive, unruly behaviour and tendency to get into fights with other boys. He was trained as a pit fighter and had his first match in the pits when he was 16. Daario rose to fame within the fighting pits earning his master so much money that at the time of his master’s death Daario was rewarded with freedom. Daario chose to fight as a sellsword for the Second Sons sometime after that.
Besides being fluent in the Common Tongue of Westeros, Daario is also fluent in Low Valyrian due to his Tyroshi origin. Daario also seems to speak some Dothraki, though it is unknown if he is fluent in it.
Daario has an unusual code for a sellsword; he won’t sleep with prostitutes and only kills soldiers who are trying to kill him, not bystanders. He does this because he feels that otherwise there is no sport and it is not exciting. Daario has said that the gods gave men two things to entertain themselves with before they die: the thrill of having sex with a woman who earnestly wants it, and the thrill of killing a man who is trying to kill you first.
Daario is a highly skilled and capable warrior. Being trained a pit fighter since the age of 12 and then fighting as a sellsword after that, mostly all of Daario’s life has revolved around fighting. During his years as a pit fighter he learned to fight with several different fighting styles; like a Dothraki screamer, a Norvoshi priest and a Westeros knight. Daario has over several different occasions proven his skills in combat: when he reveals to Daenerys that he single-handedly managed to kill both of the commanding officers of the Second Sons, when he along Ser Jorah and Grey Worm fight severely outnumbered against several guards in the streets of Yunkai, when he kills the Champion of Meereen in single combat with ease or when protecting Daenerys, Tyrion, and Missandei from hundreds of Sons of the Harpy along with Ser Jorah, coming out on top, unharmed, despite being outnumbered severely.
Daario’s weapons-of-choice are a Dothraki arakh and a Myrish stiletto, both which have gold-plated custom-made hilts in the shape of beautiful, naked women. His fighting style is based on speed and quick, accurate strikes with few, mostly finishing, blows based on pure strength due to his relatively small size and lean build compared to the larger, stronger opponents he frequently faced in the fighting pits.
Daario Naharis joins the captains, Mero and Prendahl na Ghezn, when they visit Daenerys Targaryen, who hopes to convince them to break their contract with Yunkai and fight for her instead. Daario sees through Daenerys’s bluff that she has 10,000 Unsullied, reminding her that she has only 8,000. When the Second Sons depart with Daenerys’s offer and a barrel of wine, Daario’s gaze lingers on the young queen.
Back at their own camp, Daario, Mero and Prendahl discuss the situation, with Mero and Prendahl deciding to assassinate Daenerys. At Mero’s behest, a bed slave (whom he spurns from sexual intercourse due to his self-imposed inability to make love to “property”) hands out random coins coins of Braavos, Volantis and Meereen – Daario draws the Braavosi coin that indicates he is the one to do the deed. His only response is “valar morghulis” – “all men must die”.
That night, Daario, wearing the armour of an Unsullied slips into Daenerys’ tent and takes Missandei hostage. He then presents the heads of Mero and Prendahl and informs her he has taken command of the Second Sons. Intrigued, Daenerys demands that he swear fealty to her. Daario bends the knee and swears the Second Sons, his sword, his life, and his heart to Daenerys.
Daario later assists in planning the siege of Yunkai, and is selected, along with Ser Jorah Mormont and Grey Worm to infiltrate the city and open the gates from the inside. The plan succeeds brilliantly, and Jorah and Grey Worm return to their queen triumphant. Daenerys expresses concern over Daario’s whereabouts, but he appears a moment later, presenting Yunkai’s bloodstained flag to her.
Daario is present outside the walls of Yunkai when Daenerys is greeted by the former slaves who have been liberated. He witnesses as the crowd lifts Daenerys up in the air as they shout “Mhysa” to her.
Ser Barristan and Missandei reveal to Daenerys that Grey Worm and Daario have indulged in gambling; having been at the contest since midnight and have missed a meeting as a result. She is irritated to discover that their contest is a game of who can balance their sword for the longest.
Although the prize of the contest being the honour of riding at her side when the march resumes, Daenerys assigns the pair to guard the livestock as punishment for their childish game. When they fail to move, she warns them that the “winner” of the contest must find a new queen, prompting them to drop their weapons instantly. Grey Worm’s gaze lingers on Missandei, which Daario takes as a sign that he is interested in her, and points out that this problematic given Grey Worm’s eunuch status.
Grey Worm tells Daario that he is not a smart man for saying such things, to which Daario replies that he would rather have no brain and two balls. Later, Daario slips away from his post to discuss “strategy” with Daenerys; he gives her flowers under the guise of a lesson in the botany of Slaver’s Bay, in which he points out that Daenerys must know the land she is to rule.
At the gate of Meereen, Daario volunteers to fight Meereen’s champion in single combat after Daenerys rejects the rest of her inner circle from fighting. Daario declines the use of a horse, noting that they aren’t as intelligent as humans. Daario ends the duel with ruthless efficiency, striking down the horse with his stiletto and decapitating the dazed champion with his arakh. After the Meereenese fire a volley of arrows in a symbol of displeasure, Daario urinates on the nearest one in a symbol of defiance.
After Daenerys takes control of Meereen, Daario announces at a council meeting that the Second Sons have captured the 93 ships of the Meereenese Navy on his orders. When asked by Daenerys why the Seconds Sons took the navy without being instructed to, he responds by saying that he heard she liked ships. It also comes to light that whilst Joffrey Baratheon’s death has made Daenerys’s position in her conquest of Westeros stronger, Yunkai has been retaken by the Wise Masters and Cleon has claimed dominance over Astapor.
Later on, Daario comes to Daenerys’ private quarters of the Great Pyramid and brings her flowers. As Dany refuses him, he tells he has only two talents in his life: war and women. Daenerys asks him about his loyalty and Daario swears his sword and life are hers and asks her to let him do what he can the best; to send him to kill her enemies. Instead, Daenerys focuses on the other thing Daario claims to be good at and orders him to take off his clothes.
When he leaves her bedchamber the following morning he runs into Jorah, cheekily telling him that it’s a good time to talk to Daenerys, as she is in a very good mood. Daenerys tasks Daario and the Second Sons with retaking Yunkai and killing every Master who has taken control. However, Jorah convinces Daenerys to give the Masters an ultimatum: to accept her abolition of slavery or die. She tells Jorah to “catch Daario before he leaves”, and to send Hizdahr zo Loraq with Daario and the Second Sons as her ambassador to Yunkai.
Daario, along with the Second Sons and Hizdahr zo Loraq, returns from their successful mission in Yunkai and is present within in the Great Pyramid when Hizdahr suggests to Daenerys that she should reopen the fighting pits. Daario notices Daenerys initial fustration with Hizdahr, brandishing his knife while he speaks, amusing Daenerys. Unexpectedly, Daenerys refuses to reopen the fighting pits, even in retrospect of the prospect of freedmen competing rather than slaves.
However, he later explains that he agrees with Hizdahr’s suggestion to reopen the pits. He then goes on to tell her about his life growing up as a boy who became a pit fighter himself, and how fighting in the pits made him the warrior he is today. He says he is the only one who will give her honest council. He also explains that a “dragon queen” is no queen without her dragons, which encourages her to visit Rhaegal and Viserion, who are chained in the catacombs.
Daario leads Grey Worm to a house where the alleged murderer of White Rat is hiding. He tells Grey Worm that his Second Sons overhear things that the Unsullied do not because they blend in with the local population. Daario is also able to deduce where a member of the Sons of the Harpy was hiding because he also understands fear, while the Unsullied do not. Later, he informs the Daenerys’ council that the man they arrested has very little useful information since Daario had questioned him earlier. When Mossador murders the Son of the Harpy, Daenerys has Daario behead Mossador in public, causing a riot.
Daario brings Daenerys the news that Hizdahr zo Loraq, as well as many more supplicants, are waiting for her. He states that it isn’t necessary for Ser Barristan to be present at Daenerys’s side when she talks with Hizdahr, claiming that he is very much capable of protecting Daenerys against Hizdahr himself, which leads to Ser Barristan taking a walk in the streets instead and being subsequently murdered by the Sons of the Harpy. He is present when Hizdahr yet again tries to convince Daenerys that the fighting pits should be reopened.
Daario and Daenerys wake over the dead body of Ser Barristan. Hizdahr then enters to offer his condolences. Daario suggests to Daenerys that they could pull back to the pyramid district where they can set up a base of operation so that they can efficiently start working on catching the Sons of the Harpy. Daenerys chose to rather go with Daario’s other suggestion, which involves apprehending the leaders of all the great families in Meereen and bringing them to her. Hizdahr states in shock that he is the leader of his family. Daario nods to the guards who then arrest Hizdahr.
Daario is present alongside Daenerys in the catacombs when Daenerys threatens Hizdahr and the other apprehended leaders with the use of her dragons, Rhaegal and Viserion. Daario pushes one of the leaders before the dragons and watches as the master is burned alive then eaten. Later, while Daenerys is talking to Missandei, she mentions that Daario thinks she should execute all the Great Masters.
Daario is in bed with Daenerys, asking her if Hizdahr will soon take his place beside her in her bed. Daenerys notes a hint of jealousy in Daario, which she finds amusing and sweet. Daario suggests that on the opening day of the games in the fighting pits, she should apprehend all the Great Masters, Wise Masters and all other masters of note and execute them. Daenerys responds in horror of this suggestion that she is a queen and not a butcher, to which Daario replies that “All rulers are either butchers or meat”.
Daario, along with Daenerys, Tyrion, Missandei and Hizdahr are in the Great Pit of Daznak observing the opening match which is set to take place. The match features two fighters: one large man versus one smaller man. Daario states to Daenerys that she should gamble on the smaller man because Daario thinks that speed defeats size in combat. Daario is referring to himself when he says this, because when he was a pit fighter himself he was also small, but this never stopped him from winning the fights, even when he was fighting against men that were much larger than him.
Daario goes on explaining why this is so whilst twirling his dagger around Hizdahr’s head, which makes Hizdahr nervous. Hizdahr disagrees with Daario’s opinion on this matter, saying that in his experience watching the games in the fighting pits the larger men win over the smaller men almost every time. Daenerys responds to Hizdahr by saying that he may not be the right man to speak considering Hizdahr has never fought himself. The fight eventually ends with the larger man winning, just as Hizdahr had predicted, which leaves Daario with a sour look on his face.
Daario, along with the others, is shocked when Jorah shows up as a fighter when the second match is about to commence. Daenerys allows Jorah to fight in the match, and even though Jorah is outmatched for most of the fight he does end up winning the fight in the end. Just after the match has ended, Jorah throws a spear towards the podium where Daenerys is sitting, Daario makes sure the spear doesn’t hit Daenerys by pulling her to the side. The spear that Jorah threw was revealed to be targeted towards a member of the Sons of the Harpy who had been sneaking up on Daenerys from behind. Daario looks into the audience to realise that the Sons of the Harpy are there. Daario manages to fight off and kill many of the Sons that were trying to get to Daenerys. Daario witnesses Hizdahr being stabbed repeatedly in the chest as they are trying to escape from the podium, revealing that Hizdahr wasn’t in league with the Sons of the Harpy after all as Daario had predicted.
Daario, Daenerys, Tyrion, Missandei, Jorah and a handful of Unsullied all run towards the center of the arena trying to find a way to escape – instead finding themselves surrounded by a huge number of Sons of the Harpy. Daario, Jorah and the Unsullied manage to kill several of them before they eventually realise that they stand no chance against such a huge number of Sons of the Harpy. Just as hope seems to fade away, Drogon appears in the arena scaring off most of the Sons and killing the rest. Daenerys ends up mounting Drogon on the back and flying out of the arena. Daario, Tyrion, Missandei and Jorah all look up to the sky as Daenerys flies away on Drogon.
Daario later strategises – or rather argues – with Tyrion and Jorah in Daenerys’s throne room. When Missandei arrives with Grey Worm, Daario throws a few barbs his way before firmly declaring that neither Tyrion – who has no tracking or combat skills – nor Grey Worm – who is still recovering – can come with them to track the queen down. Instead, Daario declares, Grey Worm and Missandei must lead the Unsullied in keeping the peace, while Tyrion makes sure the city’s politics don’t bring the pyramids crashing down around them. Daario and Jorah then depart on horseback to find Daenerys.
Daario and Jorah’s search takes them to the Dothraki Sea. Daario gets Jorah to admit that he is in love with Daenerys, while musing that there is no escaping men like them in the world, and that he would like to see Westeros once Daenerys has conquered it. They eventually stumble across a circle of hoof prints with Daenerys’ ring in the middle, leading them to discover that Daenerys has been taken by a Dothraki khalasar.
Daario and Jorah are climbing a hill in order to get a vantage point over Vaes Dothrak, which is where their search for Daenerys has taken them. Daario continues to make fun of Jorah about how Daenerys chose Daario over him, which annoys Jorah. Upon reaching the top of the hill Jorah lays out a plan on how they are going to rescue Daenerys, a plan which involves sneaking into Vaes Dothrak during nighttime unarmed, because if they were to get caught with weapons they would be killed (because all weapons are forbidden inside Vaes Dothrak), but if they were unarmed they could pose as merchants. Daario doesn’t like the idea of giving up his weapons, especially his dagger, and is very reluctant about it, but he eventually agrees to hand them over.
Just as he is about to hand over his dagger he notices the Greyscale on Jorah’s wrist. Jorah assures Daario that it didn’t touch him and that he is aware of the consequences it brings. Daario and Jorah then sneak in to the city during the night. They eventually stumble across two Dothraki warriors, Aggo and Iggo, in a back alley. Jorah tries to convince the two Dothraki that they are merchants whom have gotten lost in the city, but Aggo doesn’t believe their story and orders the other Dothraki to alert the city. Daario chases after Iggo while Jorah tries to fight Aggo.
Daario catches up with Iggo and breaks his neck before he can alert the others. Due to Jorah’s greyscale condition he is unable to hold his own against Aggo and is nearly killed right before Daario arrives to the rescue by stabbing Aggo in the back with his dagger that he had lied about leaving behind. Daario then attempts to cover up the stab-wound by smashing Aggo’s body with a rock, making it look like he was smashed to death and not stabbed. Although Aggo’s body is later discovered by members of the khalar vezhven, Moro quickly dismisses any cause for conflict.
As Daenerys and another Dothraki widow, Ornela, exit the Temple of the dosh khaleen to get some air they run into Daario and Jorah. Daario seizes Ornela and is about to kill her, but Daenerys makes him stand down. Jorah urges them to leave quickly before the bodies of Aggo and the other Dothraki are discovered. Daenerys, however, has another idea which involves burning down the temple where all the khals will be meeting to decide Daenerys’ fate, which would prove her power over the Dothraki in the process.
Daenerys enters the temple and after threatening the khals that they will be killed if they don’t submit to her, she pushes down all the pyres inside causing the building to set fire. Khal Moro attempts to flee out the back door but is unable to because it has been sealed from the outside and its guards have been killed by Daario and Jorah. Daario, Jorah and all the other Dothraki witness as Daenerys steps out of the burning temple alive. The Dothraki all bow to her, followed by Jorah, and Daario, who still is in shock of what he just witnessed, bows last – awed by the extent of Daenerys’s dominance.
The morning after the burning of the temple, Daario is present with Daenerys when she confronts Jorah about his recent actions. Daenerys forgives Jorah and welcomes him back to her service, but Jorah refuses her offer and rather tells her to send him away again. Jorah then goes on to show Daenerys his Greyscale infection and confess his love for, which seems to make Daario not jealous but rather sad for Jorah instead, knowing he most likely will die. Instead of sending Jorah away to die, she commands him to look for “the cure” to his infection so that he can come back to her.
As Jorah departs into the unknown, Daario and Daenerys, along with the Dothraki, start making their way back to Meereen. On their way back to Meereen, Daenerys questions Daario on how many ships she will need to take Westeros, to which Daario responds that in order to bring all the Dothraki and their horses, the Unsullied and the Second Sons, they would need a thousand ships if not more. Daario goes on to tell Daenerys that she isn’t a ruler but rather a conqueror instead as her political rule in Meereen has proven. However, Daenerys simply states that she simply takes what belongs to her.
Daenerys suddenly orders Daario and the Khalasar to stop, and she rides off for unknown reasons. After a long while, Daario announces to the khalasar that he is going after her. As he is about to leave to search for Daenerys, they hear Drogon approaching, with Daenerys on his back. Landing before her extensive horde, she reveals her true intentions to the khalasar and Daario, who looks at her with satisfaction and admiration as she promises to lead her people to victory if they stand beside her in the conquest.
Daario leads the Dothraki in their charge towards the gates of Meereen to end the masters’ siege, removing the head of the first Son of the Harpy he encounters. Following the battle, Daario is summoned by his queen. As Daenerys leaves for Westeros she breaks her ties with Daario at Tyrion’s prompting, fearing that bringing a lover to Westeros would be a detriment to her cause. Daario recognises Tyrion’s influence and asks to go with Daenerys, revealing that he has truly grown to love her, but she refuses him. Daario and the Second Sons are left in Meereen to keep the peace while a provisional government transfers power to the people.
Daario is briefly mentioned in a conversation between Daenerys and Tyrion. Daenerys describes Daario as a would-be hero, much like Drogo, Jorah or Jon Snow, who are brave enough to perform heroic but foolish deeds that will likely seal their fate, as if it was merely some kind of contest.
