House Martell

Trystane Martell

House: House Martell of Sunspear, youngest child of Prince Doran Martell

Last confirmed remaining at Sunspear as Princess Myrcella journeys back toward King's Landing without him, his betrothal to her still intact despite the violence that has surrounded her Dornish stay.

The youngest of Doran Martell's three children was never meant to carry the weight his siblings do — Arianne stands to inherit Sunspear, Quentyn was sent to gamble on dragons — and Trystane's part in his father's design is quieter: marry the Baratheon princess sent south as a hostage of sorts, and by doing so bind Dorne to the crown closely enough that no one questions where Dorne's loyalties lie while Doran's real plans mature elsewhere. He and Myrcella have, by every account the text offers, become genuinely fond of one another over their shared games of cyvasse, which a maester notes is a more solid foundation for peace between two great houses than most treaties this chronicle has recorded.

The arc of Trystane Martell

This carries the character’s road through the published novels. Read on only if you do not fear to know.

Trystane's betrothal survives the chaos of Arianne's plot and Myrcella's maiming, but his father's protection of him goes further than the marriage itself: learning that Cersei's invitation south conceals a planned ambush meant to kill Trystane in the kingswood and lay the blame on Tyrion Lannister, Doran quietly keeps his son at Sunspear and sends Myrcella back to King's Landing under Nymeria and Tyene Sand's escort instead — the visible, respectable half of a Dornish strategy whose uglier half, vengeance for Elia and her children, his father has kept from him along with everyone else.

Where the books leave Trystane Martell: Betrothed to Myrcella Baratheon since Tyrion Lannister's regency arranged the match, Trystane remains at Sunspear through his sister's failed plot and his uncle's death, apparently fond enough of his intended bride that neither the disgrace surrounding her disfigurement nor the political wreckage around them has soured the match. When word reaches Doran that Cersei's regency means to have the returning party ambushed in the kingswood — brigands crying 'Halfman' to pin Trystane's murder on Tyrion Lannister — the prince keeps his son home rather than risk him on that road. Myrcella returns to King's Landing without her betrothed, escorted instead by Nymeria and Tyene Sand.

These partings name deaths, endings, and roads not yet ridden in the books. Unveil them only if both roads are known to you — or if you do not fear to know.

Who is Trystane Martell betrothed to?

Princess Myrcella Baratheon — a match arranged by Tyrion Lannister during his regency to secure Dorne's loyalty to the Iron Throne.

Is Trystane Martell involved in Arianne's plot to crown Myrcella?

No — the plot is Arianne's alone, kept from both her father and, so far as the text shows, from Trystane as well.
