The autumn air over Ashford Meadow did not merely cool; it curdled.

Beneath a sky the color of bruised plums, the tourney ground was a sprawling canvas of scarlet and jet.

The royal pavilion loomed like a great, crouching beast of House Targaryen, its silken folds rippling with the red, three-headed dragon of the Crown.

Sitting upon the raised dais were the sons and grandsons of the late King Viserys II—the unbroken line of Princess Rhaenyra, the undisputed victors of the Dance.

They sat in their velvet finery, secure in the knowledge that history had been bled dry, bound in leather, and written in their favor.

Then, from the eastern gate, came the sound of a lone horn.

It did not blow the silver, triumphal note of the Reach, nor the stag-bellow of the Stormlands. It was a low, guttural wail, like a dying dragon gasping its last breath in the mud of the Dragonpit.

Through the parting crowds rode the specter.

He did not wear the polished silver or the lacquered black of the contemporary court. His plate was a heavy, archaic suit of enameled jade—the deep, merciless green of wildfire, or perhaps the dark pine forests of Oldtown.

Over his shoulders draped a mantle of cloth-of-gold, tarnished with the faux-patina of age. But it was his standard that struck the midday air like an executioner’s axe.

High above his warhorse fluttered a banner that had not tasted the wind in three generations:

The Golden Dragon.

Not the crimson beast of Rhaenyra’s line, but the radiant, three-headed sun-dragon of King Aegon the Second. The Greens.

A profound, suffocating silence fell over the meadow.

The laughter of the smallfolk died in their throats. The silken rustle of ladies’ fans ceased. At the royal pavilion, hands dipped instinctively toward the pommels of swords.

To raise that banner was not a statement of lineage; it was an act of high treason bound in steel, a deliberate exhumation of a war that had drowned the realm in ash.

The Mystery Knight did not bow to the dais. He merely reined his massive, black destabilizer before the royal box, his visor a blank, faceless slit of dark iron.

He raised his lance—painted in alternating spirals of green and gold—and pointed it directly at the heart of the Crown’s champions.

At the royal pavilion, the atmosphere had turned from stunned bewilderment to a simmering, toxic fury.

Prince Baelor Breakspear sat forward, his knuckles white against the armrest of his chair.

His mismatched eyes, so unlike the traditional Valyrian twin of violet, tracked the emerald shadow below.

Beside him, his brother, Prince Maekar, looked like a storm cloud clad in steel.

His jaw was clenched so tightly that the muscles bunched like ropes. Every time a knight fell, the Green Knight would wheel his horse around, the golden dragon on his banner snapping in the wind, a silent, mocking reminder:

You sit on the throne, but we still hold the lance.

"He mocks us," Maekar muttered, his voice a low growl that carried across the dais.

"He rides with the ghost of the Usurper. Let me don my armor. I will unhorse this phantom myself and see what manner of traitor bleeds beneath that green paint."

"No," Baelor said, his voice a calm, chilling anchor amid the rising panic.

"To meet him ourselves is to give his treason the weight of legitimacy.

He wants a royal confrontation. We will give him the laws of the tourney, and nothing more."

Yet, as the afternoon bled into evening, the Green Knight stood unconquered. He had shattered twelve lances. He had unseated twelve lords.

He stood alone in the center of the bloody field, his armor streaked with the dust of the Reach and the blood of his opponents, a solitary green mountain against a sky of darkening gold.

The final challenger had fallen, a young Fossoway prince who lay groaning in the dirt. The crowd did not cheer. The silence was absolute, save for the heavy, rhythmic breathing of the stranger’s warhorse.

The Green Knight trotted slowly toward the royal pavilion, stopping precisely where the shadow of the Targaryen dragon fell across.
