Percival awoke in the castle dungeons, chained to the wall. Next to him was Gwaine, with Merlin after that. They both looked like they'd taken some damage, with blood-soaked hair and broken ribs.
Percival had chains tying him tightly against the wall, and so he pulled and pulled. But nothing happened. They were all trapped.

...

Morgana looked at the two dragon eggs and the lump of metal with a strange curiosity, like she could taste power, but it was just out of her reach.
She tried opening them with spells. None worked. She tried to break through it. It stayed strong as ever. She tried to call to the dragons inside. Nothing happened.
She turned her gaze to the lump of metal. There was enough there to make a few swords, and it seemed strong. She sent it to the blacksmith to try to weaponize it. Not that it mattered anyway.
Emrys had no magic and Arthur had an army of weakened, pathetic men. They would be massacred.

...

Jenny watched Elyan. He was sleeping.
Another dragon. Told you you'd meet one.
I finally have one to call my kin. I am happy.
I know, Flamel.
Suddenly Elyan woke up with a snarl and growled lowly at the trees.
"Yes Elyan. Very evil trees there. Bet they're really scared."
Elyan continued to growl, however, and so Jenny went into his mind. It was a strange place, young and yet with a hereditary wisdom at the same time.
Jenny retreated back into herself and stood.
What's wrong?
Gwaine. She replied. Gwaine is hurt. We have to go and help him.
And so she climbed onto Flamel, held onto the spikes on his back for dear life, grabbed Elyan, and they flew off to Camelot.

...

Eragon exited the cave, looking for Gwaine and Percival, but they were nowhere to be seen. Neither were the horses or his bag with the eggs in.
"We have to get to Camelot!" Arthur spoke with an urgency in his voice that made Eragon forget about his own troubles.
"The horses are gone." Eragon replied. "How will we get back?"
"By any means possible! We have to get there now! The people are in danger!"
Then Arthur set off running through the trees with a newfound energy that baffled Eragon. He knelt at the ground and sucked the energy out of the grass. He needed as much energy as he could get. He then spoke in the ancient language and the wind picked him up. The knights also rose off the ground, and they all soared through the air towards Camelot.

...

Merlin awoke in the dungeons, with Gwaine and Percival tied next to him. They both were covered in their own blood, and Merlin could feel his hair sticking together from the beating Morgana gave him.
There were three guards outside, and he knew just how easily he could take their weapons from them and knock them out. So he spoke. And nothing happened. He tried again. Nothing happened.
He felt despair slowly envelop him like he was falling into water. He realised that if he couldn't cast magic, he was useless.
"Magic not working?" Gwaine asked looking at him.
Merlin thought of lying, but gave up. He nodded.
"Lucky I have enough for the both of us then." He said, showing Merlin his Gedwey Ignasia. He cast a spell at their chains, and all three could move again.
Gwaine then crawled over to the door, and opened it with magic. As the guards came in, Percival punched one in the face, stole his sword and killed the three guards single-handedly. He then picked Gwaine up and carried him out, as Merlin followed, afraid that if they were attacked, he couldn't protect himself.
