The Failed Queenmaker Plot is Arianne Martell’s clandestine attempt to make Myrcella Baratheon queen, a scheme driven by inheritance, vengeance, and her determination to compel Dorne into open conflict with House Lannister. Conceived as both a rescue of Dornish honor and a bid for political transformation, it instead exposes the danger of treating a frightened child as a dynastic instrument and ends with the conspirators captured and Ser Arys Oakheart mortally wounded.

Causes and Political Aim

Arianne’s plan joins several ambitions that she does not distinguish sharply enough. She wants the Sand Snakes freed, vengeance for Oberyn Martell and Elia Martell, and a taste of lion blood, but she also insists that she seeks her birthright: Sunspear, her father’s seat, and Dorne. Her declaration that she wants justice gives the conspiracy a moral vocabulary, yet the proposed crowning is also a direct challenge to Doran Martell’s cautious rule and to the Lannisters’ control of the Iron Throne.

The intended political logic is that crowning Myrcella would provoke the Lannisters and provide the war Arianne desires. Her opponent argues that the gesture would be hollow: Myrcella would never truly sit the Iron Throne, and the lion would not be easily provoked. Arianne answers that the lion is dead and wonders which cub the lioness prefers, revealing how strongly the plot depends on uncertainty within House Lannister as well as on the succession dispute itself.

Arianne also imagines the aftermath as a sweeping consolidation of Dorne. Once Myrcella is crowned and the Sand Snakes freed, she expects all Dorne to rally to her banners. She considers the Yronwoods a possible threat through Quentyn Martell, but believes they could be destroyed if they aligned with Tommen Baratheon and the Lannisters. The projected future is therefore not merely a coronation: it is an imagined transfer of power in which Arianne would command loyalty, settle internal opposition, and restore Doran Martell to the Water Gardens.

The Attempted Coronation

The plot reaches its public-facing stage when Myrcella, confused and frightened, finds herself surrounded by Arianne’s supporters. She clutches Arys Oakheart and asks why people call her Grace, what place she is in, and who the armed or kneeling figures are. When she embraces Arianne, she still does not understand the political danger; she asks why they call her queen and whether something bad has happened to Tommen.

Arianne supplies the explanation that the conspiracy requires. She tells Myrcella that Tommen has fallen in with evil men who have conspired to steal her throne. Because Myrcella is older by a year, Arianne presents the Iron Throne as hers by right and urges her not to blame her younger brother, placing responsibility instead on his counselors. The argument turns a child’s age into the foundation of a rival monarchy, while the ceremonial introductions to Arianne’s friends begin to give the supposed queenship a courtly shape.

The party is deliberately small. Seven riders leave the dust-dry ruins of Shandystone under the Moonmaid: Arianne and Arys at the front, Myrcella between them on a frisky mare, Garin and Spotted Sylva behind, and two Dornish knights at the rear. Arianne interprets the number as a good omen and imagines that singers will make the riders immortal. Yet the same arrangement exposes the plot’s fragility. A larger escort might have attracted attention, while each additional man increased the risk of betrayal; the reduced company makes secrecy possible but leaves the queenmaking attempt vulnerable to a single interception.

Interception at the Poleboat

The decisive reversal comes at a poleboat hidden beneath a great green willow downstream. The vessel is painted green and ornamented with a mermaid-shaped tiller and fish-faced rails, its decks crowded with poles, ropes, jars of olive oil, and lanterns. Garin approaches expecting a royal welcome, but the boat’s door slams open and Areo Hotah steps into the sunlight with his longaxe in hand.

Hotah’s appearance transforms the scene from a secret procession into an encirclement. He strikes the butt of his longaxe against the deck, and a dozen guardsmen rise behind the rails with throwing spears and crossbows; more appear above the cabin. He orders Arianne to yield, warning that otherwise the guards must kill everyone except the child and Arianne herself, acting by Doran Martell’s command. The demand makes the hidden structure of the plot unmistakable: Doran’s silence and caution have not meant passivity, and the supposed royal escort has been anticipated and contained.

The conspirators begin to surrender. Myrcella remains motionless on her mount, while Garin slowly backs away with his hands raised. Andrey Dalt unbuckles his swordbelt and says that yielding seems wisest. Arianne recognizes that the cause is lost, but the words urging Arys to surrender catch in her throat. Her inability to command the necessary sacrifice becomes the emotional hinge of the event: the political calculation that brought the group into danger gives way to paralysis when the life of the man who loves her is placed directly before her.

Arys Oakheart’s Last Stand

Arys refuses the practical solution. He places his horse between Arianne and the crossbows, draws his sword, and shields her with his body. After giving Arianne one last longing look, he charges the poleboat. His white cloak streams behind him as he rides headlong into a prepared position, an act Arianne recognizes as gallant but foolish only after it has begun.

The attack is immediately overwhelmed by concentrated fire. A crossbow bolt punches through Arys’s heavy oaken shield and pins it to his shoulder; another grazes his temple. A thrown spear strikes his horse in the flank, yet the wounded animal reaches the gangplank. Arys cuts down two spearmen and retains his longsword even after the horse rears and kicks a crossbowman in the face. The remaining crossbows then feather the courser with quarrels, knocking it sideways and sending horse and rider crashing onto the deck.

Arys’s resistance gives the failed plot its final tragic form. His loyalty cannot rescue Arianne, alter Myrcella’s status, or break the encirclement; it can only convert capture into bloodshed. The value at stake shifts from the possibility of a crown to the immediate preservation of life, and then from life to a doomed assertion of honor. The queenmaking attempt therefore ends not in a coronation or a war, but in the violent exposure of its limits.

Consequences and Significance

The interception defeats Arianne’s immediate objectives at once. Myrcella is not crowned, the Sand Snakes are not freed through this action, and the hoped-for confrontation with the Lannisters does not begin on Arianne’s terms. Instead, the conspirators are disarmed or compelled to yield, while Doran Martell’s forces retain control of the child and the political situation.

The plot also reveals the contrast between Arianne’s romantic vision and Doran’s method. She sees seven riders on the road to glory and imagines banners, songs, and a united Dorne; Doran’s response arrives through concealment, surveillance, and a carefully arranged force hidden in an unassuming boat. Her desire to put down his burdens becomes another sign that she has misunderstood the burdens he has already been carrying.

As a failed quest and a failed rescue, the event reverses the conventional promise of heroic return. Arianne crosses into danger intending to return with a crowned queen and a transformed Dorne, but the threshold yields no triumph or integration. The journey instead produces recognition through defeat: the child is frightened rather than commanding, the escort is compromised, the father’s caution is stronger than expected, and Arys’s devotion cannot compensate for the conspiracy’s political and tactical weakness. The plot’s decisive lesson is that ambition and grievance, when organized around a vulnerable claimant and sustained by wishful forecasts of popular support, lead not to liberation but to exposure, capture, and irreversible loss.
