Slowly, a wind rose around Emrys, starting softly and swelling into a gale that whipped at Uthers clothes. He struggled to remain upright. In the dancing black light, Emrys crackled with power, radiating an aura of unrelenting danger. "You underestimate me, Uther Pendragon, King of Camelot!" he announced over the wind, which continued to rise, though it was eerily calm where Emrys stood toying with the sword that had been thrown at him seconds earlier. "It was I who killed your old friend, Nimueh! It was I who singlehandedly defeated Sigan, the most powerful sorcerer Camelot has ever known! I have seen the future in the Crystal of Neahtid, I have forged a sword that can slay the dead, and I am the last of the Dragonlords. Think before you challenge me, Old King!"
Then as sudden as Emrys' entrance Uther felt the dagger of the Blood Guard pressing into his neck. "Neither should you underestimate me, Father. I have become one of the only people you would run and hide from by your own hand. You will die and Arthur will cry and neither I nor Emrys will care. Because the tears of Albion are barely beginning to fall." declared the voice of the terrified king's bastard child. The child he had raised removed her dagger from his throat and sauntered over to the smirking figure shaping the lump of metal that had been Uthers best sword. She held his hand and, as both pairs of eyes glowed a fierce and merciless gold, Uther heard their joined voices in his head 'However it is not at our very capable hands you will die, Uther Pendragon, but at a certain victim of your tyranny's claws.' He saw the mirror smirks on the faces in front of him and, his mouth wide with silent and completely logical terror, he was grabbed by a silvery claw.
Mordred sat straight up in the druid camp that had been his sanctuary for nearly a year and walked out of his tent. He went over to his guardian and let him know of what had happened and where he was going. The druid place a protection ward over the young boy and bringing food out the tent sent the child upon his way. As soon as he had got a safe distance from the camp Mordred let his magic surround him. His eyes morphed from his light blue to a molten gold and he appeared perfectly at ease in the middle of Emrys and Morgana's camp. Emrys turned around smiling, Morgana still asleep next to the fire. "Hello Mordred. We were wondering when you'd turn up. Saw that vision of Uther as well then?" queried Emrys with dark laughter in his eyes at the memory of that vision. 'I wasn't expecting you. Care to explain what happened?' murmured Mordred in Emrys head.
The apathy from that time slid back up in front Emrys' ice cold eyes and he showed Mordred what had happened since Morgana and Morgause's fall from power. The boy's eyes widened but that was the only outward sign of his feelings. His thoughts were blacker than they had been since Uther the despised tyrant had killed his father but he was also surprised. They had seen his mother. He could barely remember her. "Can you take me to my mother?" he murmured in a strange wistful voice. Emrys nodded and with a smile he poked around in Morgana's mind till she woke up. She blinked and seeing Mordred her mouth sprang into a warm smile and she hugged him close. Emrys smiled at the sight and quickly filled Morgana in on what she had missed. She nodded, Emrys' eyes flashed a gentle amber and they were transported to The Isle of the Blessed.
Nimueh saw the spiral of wind form in the courtyard and she appeared there on instinct. As soon as they appeared fully she gasped. She hadn't seen her son for so long. Not fully distracted by her son she noted Emrys' eyes, they were as cold as the night sky and it seemed as if this upset him, seeing mother and son together. Morgana noted that as well so as Mordred ran forward to hug his mother Morgana murmured in Emrys' mind 'Don't let the past block our future, Emrys. I know, even though you hide it, it still hurts. I understand. So no freak lightning killing any of us, Okay?' She was trying desperately to make light of the situation because, as she had reached into his mind, she had seen what he was thinking and, for the first time, she was actually scared. The anger in him made her want to run and hide, hide from the darkness she had befriended, but she knew that she wouldn't run away from him. He was the eye in her storm; it was safer to be close to him than far away.
Emrys' mind was as dark as Morgana's raven locks he thought of his mother and felt no sadness. All the apathy and self pity had evaporated leaving behind the molten anger that shot through him like Serkets poison. He kept his eyes closed like they had been in Camelot. The thoughts of Camelot morphed into every hurtful word, every day in the dungeons. He had thought he was properly angry at his mother's death but adding all of it on top he felt like he could make the world burn with a single thought and, he reasoned with a slight smirk gracing his ice cold face, he probably could.
Nimueh looked up at Emrys and Morgana and said "Thank you. I will repay this. Keep a weather eye out for me because I will help you end this." her voice full of joy for the first time in many years. Mordred smiled and nodded and spoke two words in his friend's heads 'Thank you.' Emrys and Morgana smiled and turned away, disappearing in the familiar whirlwind.
As soon as they arrived back at their camp they saw a hooded figure going through the bags, not noticing the startled Morgana and the emotionless Emrys behind him. At least until he found himself being pulled apart by the moving trees surrounding him. Morgana snuck a glance at Emrys as he manipulated the wood to hold the thief in place and her eyes widened. He looked…different. He shook his shoulder a few times and a grimace passed across his face. Then she realized why he looked different. Emrys' iris' were neither amber nor gold but a merciless black that as she looked slightly closer shone every colour. They were like black opals. As she stared in wonder the man began to scream she let him shriek for a few minutes and then whispered 'That's enough Emrys. We've all the time in the world.' in the dark mans head. His eyes faded back to the just as cold blue and they both smirked.
Then Morgana sauntered up to the terrified man and murmured in his ear "What in the name of the Gods did you think you were doing? Robbing the most powerful sorcerer of all times home? I think we should show you why that was a bad idea…" She heard Emrys' small chuckle and reached into the paralyzed mans mind and continued "After all Alexander, you only do it for thrills. It's my turn to sort out problems today Alexander so if I were you I'd close my eyes and pray to your Gods and hope I'm in a good mood. Because this most definitely will hurt."

Just want to say a huge thank you to everyone who has bothered to read this far. I'm developing writers block here so any Dark!Merlin things you know about would be helpful.
