The Warlock's Fall

"Please," he begged, tears tracked down his stormy blue eyes. "I don't know where else to go."

The witch merely smirked at his broken state. "You want to join me, Merlin? Prove it," she hissed.

"I'll do anything."

Morgana sighed dramatically. "I've heard this story a thousand times." She clutched his chin and forced his eyes to meet hers. "You, the famous Emrys, was supposed to unite Albion along with the Once and Future King."

Merlin avoided her supercilious gaze.

"But the poor little king feels betrayed, doesn't he?" she crooned. "He wasn't so supportive when you told him the truth, was he? And you want revenge."

Merlin's eyes flickered up to hers for one second. She could see hurt clear in his eyes, but desire and power lay hidden underneath. Hurt and power that she could easily manipulate.

She laughed harshly. "It's time to rewrite these legends, Merlin. Together."

The sky was a perpetual black, the air shimmering with remnants of the oldest and darkest magic. The streets were lined with blood. Every inch of the city could hear the wretched cries of mothers, children, men and their families.

And this was all Merlin's doing. Camelot had fallen. Fallen to the feet of one warlock, and one warlock alone.

He simply marched into the castle, without any backup. No army could match his power. All of the knights fell with one wave of Merlin's hands. They didn't get up.

Another wave had King Arthur surrounded by a ring of burning flames.

Merlin's eyes blazed gold in front of Arthur for the second time.

The first time, Merlin had been the one pleading, with tears in his eyes. It was funny how the roles had reversed.

"Merlin." He held up his sword in a weak attempt to defend himself. "Why are you doing this? I thought... I thought you were my friend." His voice broke. "Please."

Merlin raised both of his hands, palms facing Arthur menacingly. "I was always there for you Arthur," he stated, voice unwavering. "And you never were."

Without warning, Arthur's sword clattered to the floor, and he landed next to it.

Merlin ignored Arthur's pleas. His eyes flashed gold.

The King of Camelot took his last breath in a wasted attempt to apologize to a revenge bent man who was once his friend.

"You've done well, my friend." Morgana stood next to Merlin as they watched the defeated city from afar.

Camelot was hers. Her wish had been fulfilled. He had no use for her.

"Ábredwe," she whispered at him.

Merlin did not collapse like he should've at her curse. He turned, and regarded her shocked face. "I thought were friends, Morgana," he said indifferently.

Her hand flew to her throat. She couldn't breathe. Merlin flicked his wrist and she fell to her knees.

"It's a shame, too. We could've rewritten the legends. Together," he said bitterly, throwing her words back in her face.

He muttered something, some spell she couldn't quite here, but it ripped her insides in the way only dark magic could.

Morgana gasped, struggling to breathe. In her haze of pain, she managed to choke one word out. "Why?"

Merlin's face was set. He didn't flinch, not once, when she suddenly let out an agonizing scream.

"Please don't leave me," she breathed when Merlin turned away from her.

"You should've killed me when you had the chance, Morgana," was all he spoke before abandoning her to die on the forest ground.

Ábredwe means kill.

I would love it if you could please leave some advice on how to improve on this oneshot... I'll take any criticism :D
