The group stood at the top of a small hill, which rolled down to meet the waters of a lake, containing an island. It seemed like an eerie place, the fog half covered the water making the Isle almost invisible.

"The Isle of the Blessed." Arthur said finally, breaking the silence

Merlin spoke quietly to the bridge keeper while Arthur stayed with the knights, after a few moments the young prince waved them over and into the long boat. The knight's eyes widened as the boat began to move all by itself,the princes just glanced at one another, knowingly. A screech echoed through the air, unlike the cries of the dorocha Merlin felt a slight pull in his chest.

"What's that?" Leon asked

"I really hope I'm wrong..." Merlin muttered as a wyvern dove out of the sky. Wyverns were dragons, that explained the pull, hopefully that meant he could speak to them. Percival was knocked over as another wyvern joined it's friend, he had no choice.

"s'enthend' apakhorein nun epello!" He hissed under his breath, nobody noticed over the wyverns and swords clashing.

"See?" Gwaine stated proudly, "That's how you deal with them, you frighten them off with a display of superiority!"

"We need to keep moving." Arthur interrupted.

They made their way through the twisting corridors more wyverns swooped over them causing the group to duck.

"Sires! You must go on!" Leon yelled, "We'll fend them off."

"Gwaine and I will go with them!" Lancelot yelled giving the other knights a nod as he ran after Merlin and Arthur.

"Good luck!" Gwaine called to the remaining knights as he joined them.

...

The alter stood in the middle of the courtyard, after the fight with the wyverns the area was scarily quiet. The most unnerving part however, was the large black rippling tear that floated in the air, the veil. The horrible woman Merlin had seen appear before him was there, in her dark cloak and staff grasped between her pale fingers.

"It's not often we have visitors." She grinned

"Put an end to this." Arthur ordered, "I demand that you mend the veil between the worlds."

"It was not I who who created this horror," She drawled sounding bored, "Why should it be I who stops it?"

"Because innocent people are dying!" Merlin exclaimed.

"Indeed." The Cailleach laughed.

Gwaine's face twisted with rage and he charged, sword raised. Merlin tried to call out to warn him but it was too late, the calleach threw him back with a wave of her hand. The magic threw the knight backwards, knocking him out as he slammed against the hard floor.

"Is that the best you can do?" She laughed

"I know what you want." Arthur said seriously.

"And are you willing to let me have it?" She asked curiously

"I'm prepared to pay whatever is necessary." Arthur replied

The Cailleach waved him over, determinedly over to her to her, no fear on his face.

"I'm sorry," Merlin whispered, "Forb Fleoghe."

The world seemed to slow down as Arthur fell backwards, his eyes locking with Merlin's for a second. They were filled with fear and anger, his brother knew what Merlin was going to do. Arthur stilled as he hit the ground, Merlin could feel Lancelot's eyes on him.

"I understand." He said quietly.

"So, Emrys, you choose to challenge me after all" The Cailleach interrupted, "Will you give yourself to the spirits to save your brother?"

"It is my destiny." Merlin replied, he would always protect his brother. He made his way to the alter, face strong and not betraying the worry he felt.

Arthur would always go first.

"Perhaps. But your time among men is not yet over, Emrys, even if you want it to be." She replied mysteriously.

"What?" He gaped, suddenly he realized her eyes were not on him, but on something behind him near the veil.

He spun around to see Lancelot facing the veil, he turned and smiled at him.

"No!" Merlin cried shaking his head.

Lancelot continued his sad smile and before the prince could do anything, he turned, opened his arms and walked straight into the veil. Shadows enveloping him completely.

"No! NO!" Merlin cried, he couldn't stop himself.

The veil twisted and shimmered before sealing up, leaving Merlin standing in the empty courtyard. The Cailleach had gone too. The prince was left standing with his unconscious brother and friend, gaping at the place where Lancelot had been standing.

"N-no..." He breathed, horrified.

He felt himself sink to his knees after an unknown amount of time. It was all his fault, once again he'd failed somebody and they'd paid the price. The faces of Morgana and his father flashed through his mind, this was even worse. Lancelot was the most loyal, kind and selfless person he'd ever known.

And he'd died for him. To keep his promise to Arthur about keeping him safe.

It was all. His. Fault.

He felt the tears sting his eyes as he fell forwards onto his palms. He was so busy being distraught he didn't hear Arthur moan as he came to.

"Merlin!" He cried.

Merlin barely felt Arthur gripping his shoulders as he fell to his knees in front of him, the warlock didn't even look up.

"Merlin! Merlin are you alright?" Arthur asked hurriedly, "Please tell me you're not hurt!"

He opened his mouth to tell him he was fine but all that came out was a strangled sob. Arthur's grip intensified. The tears began to fall as Merlin looked up at his brother finally, he must of looked such a mess.

"L-lance-Lancelot." He choked out, "He-he..."

The prince couldn't get anymore out. He collapsed onto Arthur's shoulder.

And sobbed.

...

Later, Merlin would remember the trip back to Camelot as a pain filled blur. Time seemed to go so fast, yet agonizingly slow at the same time. Lancelot's funeral was well attended, Gwen sobbed. Merlin watched on in silent mourning, he used up all his tears on the Isle.

Arthur would be lying if he said he wasn't saddened by Lancelot's death, it hurt him deeply. Lancelot had been loyal and then most nobel knight he'd ever know. But, deep down he thanked the man.

Because it was him who died.

Not Merlin.

I'm not sure but I am going to switch up a few things, for one I'm not going to do "The Wicked Day" just yet. I think I will do it later on, but it will happen. As a result some of the episodes might be out of order slightly.
