Chapter Text
The bandits came from the tree line like shadows given teeth. Arthur had his sword drawn before the first cry rang out, steel singing free of the scabbard as he pivoted toward the rush of bodies.
They were outnumbered. Six knights against what looked like twenty men, ragged and desperate, pouring from the dark wood on either side of the forest road.
"Formation!" Arthur barked, and his knights closed ranks around the supply wagon. Metal clashed against metal. A man lunged at him with a rusted axe and Arthur cut him down with a single efficient stroke, already turning to meet the next. It should have been manageable. It would have been, if not for the archer.
Arthur didn't see the bolt until it was too close.A black streak aimed at his unguarded back while he engaged two swordsmen. He heard the snap of the bowstring, felt the displaced air, and knew with cold certainty that he couldn't turn in time. The bolt stopped. It hung in the air, trembling, wrapped in light that was not light. It was something deeper, something that hummed against Arthur's skin like a plucked harp string. Then it fell harmlessly to the mud.
Arthur dispatched the swordsman in front of him and spun. Merlin stood three paces behind him. His hand was outstretched. His eyes were gold.
Not the blue that Arthur knew as well as his own reflection. Gold blazing, molten, inhuman. The color receded even as Arthur stared, bleeding back to blue, but the damage was done. The image seared itself behind Arthur's eyelids like staring into the sun.
The remaining bandits were fleeing. The knights gave chase. Arthur heard none of it. "Arthur." Merlin's voice was barely above a whisper. His outstretched hand dropped to his side. "Arthur, I can explain"
"Don't" The word came out flayed, stripped of everything kingly. Arthur's grip on his sword hilt was so tight his knuckles had gone white. His chest felt caved in, as though someone had taken a war hammer to his ribs.
Merlin's eyes , those treacherous blue eyes, were wide with a terror Arthur had never seen in them before. Not when they'd faced griffins or wraiths or armies. This was different. This was the look of a man watching the ground open beneath his feet.
"How long?" Arthur's voice was quiet. Dangerously quiet.
"Arthur please-I"
"How long, Merlin?"
A beat of silence. The forest dripped around them, indifferent. "Always," Merlin said. "I was born with it."
The words landed like a physical blow. Arthur took a step back. Born with it. Every day. Every hunt, every battle, every evening by the fire where Arthur had spoken freely, trusted completely, believed he knew the man beside him. Every single moment had been a lie.
His father's voice echoed in his skull, unbidden and unwelcome. "Magic corrupts. Magic deceives. You cannot trust a sorcerer, Arthur. They will smile at you and slide the knife between your ribs."
"You lied to me." Arthur's voice cracked on the last word and he hated himself for it. "Every day. You stood beside me and you lied."
"I wanted to tell you." Merlin's hands were shaking. "Every day I wanted to tell you. I was afraid tha-"
"Afraid that I'd find out what you really are?"
Merlin flinched as though struck. Something shifted behind his eyes.Not golden time, but something wounded and dark. "You don't know what I am."
"I know exactly what you are." Arthur's lip curled, and even as the words formed he could feel them cutting his own tongue, tasting of bile and grief. "You're a sorcerer. You're everything my father warned me about. You're a..."
He couldn't say it. But Merlin heard it anyway. The unspoken word hung between them like smoke. "Monster"
Merlin's expression shuttered. The terror drained from his face, replaced by something worse, resignation. As though he had always known this moment would come. As though he had rehearsed it in the dark watches of the night, lying on his thin cot in Gaius's chambers, staring at the ceiling and waiting for the world to end.
"Then pass your judgment, my lord," Merlin said, and his voice was steady now, steady and hollow. "You're the king."
Arthur moved before thought caught up to instinct. His sword swept in a short, vicious arc, not a killing blow, not aimed at the heart or throat, but across Merlin's left forearm. The blade bit deep. Blood welled immediately, dark and shockingly red against Merlin's pale skin.
Merlin gasped but didn't cry out. He pressed his right hand over the wound and stared at Arthur with an expression that would haunt the king for years to come. Not anger, not hatred, but a grief so vast it seemed to swallow the forest whole.
"So you remember," Arthur said, and his voice was someone else's, something forged in Uther's court. "So you never forget what happens when you deceive your king." He sheathed his sword. His hands were trembling.
"You are banished from Camelot. If you are found within its borders after sunrise, the sentence is death." The words tasted like ash. "Go."
Merlin stood there for a long moment, blood dripping from between his fingers into the mud. He looked at Arthur the way a man looks at a door closing for the last time. Then he turned, and walked through the trees.
Arthur watched until the shadows swallowed him. He stood in the silent road with his knights returning behind him, their voices fading to nothing as they saw his face. No one spoke. No one dared. The king stood alone in the darkening wood, and somewhere deep in the marrow of him, in a place he would not acknowledge for a very long time, something broke that would not easily be mended.
