Lord of Sunspear
|Allegiance||House Nymeros Martell|
|Died||In 83 AC, at Cape Wrath|
|Book(s)||Fire & Blood (mentioned)|
In 61 AC, knights of the Seven Kingdoms marched into the Red Mountains to eliminate a Vulture King. Morion's father, the Prince of Dorne, kept Dorne out of the conflict, leaving the Vulture King to his fate in Lord Rogar's War. Prince Morion bristled at his father's apparent cowardice.
When his elderly father died, Morion succeeded him as the Prince of Dorne and Lord of Sunspear during the reign of King Jaehaerys I Targaryen. He was still angered by his father's inaction during Lord Rogar's War and wished to wash the slight away with an invasion of the stormlands. Assembling his hosts at Ghost Hill and the Tor, Morion loaded his Dornishmen onto the ships of pirates from the Stepstones, sellsails from Myr, and corsairs of the Pepper Coast. He intended to land his armies on Cape Wrath, hoping to take the stormlords and King Jaehaerys unaware. However, it took the Prince of Dorne nearly a year to load his hosts aboard the ships and, by that time, spies and friends of the Iron Throne among Morion's court and bannermen had informed the king of the prince's plans.
While Lord Boremund Baratheon awaited the Dornish on the shores of Cape Wrath, King Jaehaerys and his sons took their dragons to burn the Prince of Dorne's fleet. Not a single Dornishmen made it to shore alive, nor did the Iron Throne lose a single man. Morion died during his attempted invasion, called the Fourth Dornish War, in 83 AC. He was succeeded by Mara Martell.
