Cyvasse

Cyvasse is a board game played with ten kinds of pieces, each possessing distinct attributes and powers, on a board whose arrangement changes according to how the players set out their home squares. Made from squares of jade, carnelian, and lapis lazuli, it is presented not merely as decoration or diversion but as a structured exercise in foresight, placement, and opposed intentions. Its introduction to Dorne through a trading galley from Volantis, followed by its spread up and down the Greenblood by the Orphans of the Greenblood, gives the game a history of movement and exchange before it becomes embedded in Dornish court life.

Rules, Materials, and Cultural Setting

Cyvasse has ten different pieces, and each piece has its own attributes and powers. The board is not fixed: the players determine the arrangement of their home squares from game to game, making the opening position part of the contest rather than a neutral constant. This combination of varied pieces and mutable starting conditions is what makes the game difficult for Ser Arys Oakheart. To him, its complexity is maddening, while the Dornish court is described as being mad for it.

The game’s materials reinforce its status at court. Myrcella Baratheon and Trystane Martell play across ornate boards marked by jade, carnelian, and lapis lazuli, so the contest is simultaneously a children’s pastime and an object of aristocratic display. The game’s route from Volantis to the Planky Town and then along the Greenblood also places it within the traffic of the Narrow Sea and Dorne’s river settlements. Cyvasse is therefore not treated as an ancient, immovable custom; it is a recently arrived practice that has been adopted, circulated, and made socially meaningful by the region that receives it.

Myrcella and Trystane’s Games

Myrcella plays Cyvasse with her betrothed, Prince Trystane, in her chambers in the Tower of the Sun. When Ser Arys leaves her, she is bent over the gaming table opposite Trystane, her full lips slightly parted and her green eyes narrowed in concentration. Trystane took to the game at once, while Myrcella learned it in order to play with him. Though she is not yet one-and-ten and Trystane is three-and-ten, she has recently been winning more often than not, and Trystane does not appear to resent the reversals.

Their games give the political marriage a form that is more intimate and less ceremonial than the plans surrounding it. The two children look markedly different, with Trystane’s olive skin and straight black hair set against Myrcella’s pale complexion and golden curls, yet the game places them on equal terms: each must read the other’s choices, answer an arrangement, and accept the possibility of defeat. Ser Arys hopes that Myrcella will find more joy in her Dornish boy than Queen Cersei Lannister found with King Robert Baratheon, and Cyvasse becomes one visible sign of that hoped-for companionship.

Trystane’s attachment to the game also reveals the limits of political calculation. After Myrcella is injured and lies at her bedside, he wants to sit beside her and play Cyvasse. Arianne Martell dismisses the request by claiming that Myrcella has a childhood illness and should be left alone, but the proposed game remains significant: even amid the queenmaking plot, the children’s relationship continues to seek expression through play rather than through the adult struggle over succession.

From Pastime to Political Metaphor

Cyvasse acquires its strongest political meaning through the succession dispute involving Myrcella. Tyene Sand argues that Myrcella is older than her brother and therefore should inherit the Iron Throne under Dornish law. She distinguishes that local rule from the succession custom of the Seven Kingdoms, where a son comes before a daughter, and insists that the law preserved for Dorne after Princess Myriah’s marriage to King Daeron applies because Myrcella is physically in Dorne. The legal argument turns the child at the gaming table into a possible queen, while the game itself supplies an image of pieces being positioned toward a contested end.

Arianne’s conversation with Ser Arys Oakheart develops the same analogy through history. She invokes the first Viserys’s intention that his daughter Rhaenyra succeed him and recalls how Ser Criston Cole, the Kingmaker, chose another succession, set brother against sister, divided the Kingsguard, and helped bring about the Dance of the Dragons. Her argument is not simply that precedent exists; it is that claims to lawful rule depend on who moves first, which custom is invoked, and which institution is willing to enforce it. Cyvasse’s mutable board thus echoes the unstable board of dynastic politics, where the apparent rules are themselves contested.

The analogy remains deliberately incomplete. A game has declared pieces, visible positions, and bounded powers, whereas the political struggle over Myrcella depends on competing legal systems, secrecy, persuasion, and violence. Dornish inheritance law, Andal custom, the history of the Targaryen succession, and the authority of the Iron Throne do not form one harmonious rulebook. Cyvasse gives the characters a vocabulary for strategy, but it cannot make the political contest fair or predictable.

Doran’s Lesson to Arianne

Prince Doran Martell makes the game an instrument of instruction when he has a Cyvasse table placed in Arianne’s chambers. Her immediate response is bewilderment: she wonders who she is meant to play with and suspects that his gout may have robbed him of his wits. Doran answers that she is to play by herself. His point is that one should sometimes study a game before attempting to play it.

The lesson follows Arianne’s failed attempt to turn Myrcella into a queen. She has acted within a field of competing laws and loyalties without fully understanding the positions of the people around her, and Doran redirects her from immediate action toward analysis. The solitary table transforms Cyvasse from a shared amusement into a discipline of preparation. It asks Arianne to examine the board before moving a piece, just as political judgment requires her to understand motives, alliances, available powers, and possible consequences before committing herself.

Doran’s use of Cyvasse also changes the meaning of the game’s pieces. In the children’s chamber, movement produces companionship and friendly victory; in Doran’s chamber, the same apparatus becomes a silent diagram of succession, deception, and delayed action. The game does not erase the emotional stakes of the queenmaking plot, but it supplies a formal language through which Doran can address Arianne’s strategic failure without reducing the lesson to a direct accusation.

Strategic Form and Narrative Significance

Cyvasse functions as a recurring image of power because its central features are also the features of the surrounding political world: unequal capacities, changing initial positions, concealed intentions, and outcomes determined by sequences of choices. Myrcella’s success against Trystane suggests intelligence and adaptability, but it does not grant her the authority to rule. Arianne’s political action shows the danger of moving before the whole board has been understood. Doran’s response proposes study, patience, and strategic distance as alternatives to impulsive intervention.

The game also exposes a contrast between apparent innocence and consequential design. Myrcella and Trystane play as children, yet their betrothal is part of a plan to unite claims and potentially challenge the existing order. Arianne’s queenmaking scheme treats Myrcella as a piece in that design, while Doran’s lesson implies that even the player may be misreading the board. Cyvasse therefore compresses the novel’s politics into a material object: beautifully made, intricate in its operations, entertaining in ordinary use, and ominous when the same logic is applied to human lives.
