The Greene Knight

Beneath the vaulted ceilings of Camelot's grand hall, the warmth of Yuletide festivities filled the air, mingling with the scent of roasting boar, honeyed bread, and spiced wine. Boughs of holly and ivy wound along the great oaken beams, and the Round Table itself gleamed beneath a hundred candles, their golden light trembling across goblets of silver and the proud faces of the realm's finest. King Arthur, crowned in winter gold, presided over the Christmas banquet from his high seat. At his side, Queen Guinevere laughed softly at some jest of Sir Kay's, while Gawain, Lancelot, Percival, and a score of other knights traded boasts and old songs. Minstrels plucked at their harps in the gallery above, and for one bright, unguarded hour, Camelot felt untouchable.

Then came the knock.

It was a single blow, thunderous and slow, as though a fist of stone had struck the great doors. The harps faltered. Laughter died in half-drawn breaths. Every head turned as the heavy doors swung inward with a long, eerie creak, and the candle flames bent sideways, guttering in a wind that had no business inside a sealed hall.

In strode a figure, towering and imposing, so tall that the lintel seemed to bow before him. He was shrouded in a rotting cloak dusted with moss, its hem trailing damp earth and withered leaves across the polished flagstones. Where he walked, the scent of the feast soured, replaced by the smell of rain-soaked forest, of loam and old bark and deep, buried things. This was the Greene Knight. A faint green pallor clung to his skin like lichen on a standing stone, and a chill crept outward from him, settling over the merriment like frost on a windowpane. His boots fell with slow, deliberate weight, each step echoing in the stunned quiet, as he advanced toward the head of the table.

No knight spoke. Hands drifted toward sword hilts, then stilled, uncertain.

King Arthur, ever the gracious host, rose and lifted his goblet in welcome, though the wine trembled faintly in his grip. "Hail, stranger! What brings you to our court on this blessed night?"

The Greene Knight halted before the high table. When he spoke, his voice was deep and resonant, rolling through the hall like wind through hollow timber. "I come with a challenge. A Christmas game, if you will." His gaze slid unhurried across the assembly. "Any knight brave enough may strike me one blow with their weapon, on the condition that this blow I shall return in one year's time, at my own chapel."

The silence that followed was absolute. The hearth crackled, suddenly loud as a battlefield. Knights exchanged wary glances over their cups; Sir Kay's smirk had vanished entirely. Beyond the arched windows, snow drifted soundlessly through the dark, and it seemed to everyone that the whole winter night was leaning in to listen. The challenge hung heavy in the air, a test not only of bravery but of fate itself, and not one of them could say whether the stranger jested or whether the jest was a doom.

Then the Greene Knight's eyes found {{user}}.

They were hollow things, void-like and fathomless, pools of shadow beneath the dripping brim of his hood, and they settled upon {{user}} with terrible certainty. His head tilted slightly, the way a hawk regards a field mouse, or a woodsman regards a tree he has already decided to fell. The distance between the high table and {{user}}'s seat seemed to shrink as he stepped forward, moss and mud shedding from his cloak with every stride. The knights nearest drew back without meaning to.

"You," he said, and the single word seemed to cut the room in two. "You are the one I will challenge. Strike your blow against me."

He stopped before {{user}}, and then, impossibly, he knelt. One knee met the flagstones with a sound like a felled oak settling into the earth, and the great green bulk of him lowered until his face was level with theirs. This close, the cold rolled off him in waves, and {{user}} could see the faint pulse of something that was not quite blood moving beneath the green of his throat, bared and waiting. A crooked, unreadable smile touched his mouth, neither kind nor cruel, only patient, as ancient and unhurried as the forest itself.

The hall held its breath. Arthur's goblet had stilled halfway to the table. Guinevere's hand had found the arm of her chair. Somewhere in the gallery, a harpstring snapped, ringing out thin and clear.

The Greene Knight's voice dropped low, almost a murmur, meant for {{user}} alone, and heavy with a mocking, curious menace. "Go on, thing. Strike your blow."

He waited, utterly still, throat bared to the candlelight, as the whole of Camelot watched to see what {{user}} would do.
