A/n: Hey you all this is what would happen Arthur lived and gave Gwen babies. I do not own Merlin just my oc's, if I did the show would have never ended like that. This story will be separated by episodes surrounding the princes, the princess, the king and queen and Merlin or just the royal family and Merlin taking trips or telling stories and what not.
Prologue pt.1 (The princes)
Llacheu was Arthur and Gwen's first born.
He was the future king of Camelot. Upon his arrival druids came with their blessings.
"Riordan" Merlin greeted the druid from his place by the throne room doors.
The older man smiled at the former servant, "Emrys, I see you are well" He greeted.
Merlin gave a playful grin, "Between you and me, Arthur's still insufferable." He said.
"Merlin" Arthur mumbled quietly while gently cradling Llacheu in his arms with Gwen's hand rested on his shoulder.
"Sire"
"Shut up"
"My lord, my lady" Riordan said bowing to the king and queen.
"Riordan, as always it is a pleasure to see you." Gwen greeted.
"It's my understanding that you are here to bless my son." Arthur said.
"Our child" Gwen corrected.
"Of course" Arthur said looking to his queen and smiling
"Yes my lord, it will not harm the child but just bring him good fortune" he explained.
"Very well" Arthur said reluctantly handing over his child.
Riordan held Llacheu and placed his palm to his head.
"He will be very strong, a great warrior" Riordan commented
Arthur huffed in pride, "Like his father"
Merlin and Gwen laughed, "Let us hope his head is not as big" Merlin said.
Riordan then handed Llacheu to Gwen while Arthur glared at his advisor.
"Your majesties," Riordan said bowing.
He then walked away giving Merlin that chilled his bones. Merlin bowed before quickly following Riordan.
"What happened?" Merlin demanded as he followed him down the corridor.
Riordan halted and turned to Merlin, "He will have a short future if he grows up to be how his father was when he was a boy, then mark my words Emrys, his pride will be his downfall, and it will be the death of him." With that he turned and walked away.
Merlin watched after him, his heart pumping. Llacheu would not die, he couldn't.
"Merlin, there you are," Gwen said walking the corridor with Arthur by her side.
Merlin looked at the baby in Gwen's arms and winced. He made the king and queen happy and so far he was the only heir to the throne, he couldn't have a short life, he just couldn't.
"Sorry I just wanted to say goodbye to Riordan." He said.
"No need to explain yourself Merlin, just see to it Llacheu's room is set for him to rest" Arthur said turning to his wife and his child.
"Yes my lord." He said walking away.
Nine months later Prince Thomas was born. This time Merlin decided to bless the prince.
Arthur held Llacheu in his arms while Gwen held Thomas.
Merlin smiled at his two friends feeling drawn to Thomas, he had an idea why but he dare not say it out loud. He hadn't experienced a feeling so small yet so strong before.
"Speak your mind, Merlin" Arthur said finally looking up from his two sons.
"It's nothing, it's just…" Merlin started looking at Thomas.
"What is it?" Gwen asked in concern.
"Nothing, it's just… I can feel him."
Arthur glared at his advisor, "Pardon?"
Merlin understood what he was trying to say and quickly shook his head, "No, no, not like that, it's just I can sense magic." He explained.
Arthur and Gwen's eyes widened in surprise, "You don't suppose…" Gwen trailed off.
"He couldn't" Arthur denied.
Just then Thomas opened his eyes which were amber then flashed back to brown.
"Oh my god" Gwen gasped.
Arthur was left speechless.
"A Pendragon born with magic" Merlin marveled. "May I" He asked Gwen.
"Of course" She replied handing over Thomas to Merlin who had happy tears in his eyes.
Merlin touched Thomas's head and closed his eyes. Images of Thomas protecting Llacheu as he did with Arthur played behind his eyes. "Fair, kind, brave" a voice whispered
"He will be fair kind and brave" he said.
