A really engaging plotline could be Merlin having to teach Arthur about the ways of the Dragonlords. Arthur, being a king, would need to understand this new aspect of Merlin's life in order to better protect his kingdom. Merlin could show Arthur the magic and wisdom associated with being a Dragonlord, and they could form an even stronger bond through this shared knowledge.
Perhaps a plotline where Arthur has to deal with the political implications of Merlin being a Dragonlord. This could involve other kingdoms either fearing or trying to use Merlin for their own gain, and Arthur has to protect him while also managing diplomatic relations.
One interesting plotline could be Arthur's initial shock and then his gradual acceptance of Merlin's new identity. He might start to see Merlin in a whole new light and realize how much power Merlin truly holds.
Well, obviously Merlin and Arthur are the main characters. Merlin is the one whose secret as a Dragonlord is revealed, and Arthur is the one who discovers this secret.
One possible secret could be that Merlin is a powerful sorcerer from an ancient and powerful magical lineage. Maybe his family has a long - standing connection to Camelot that has been kept hidden.
One interesting plotline could be the knights and Arthur facing a new, powerful dark magic threat that only Merlin's unique powers can help them overcome. They might journey to a far - off land in search of a magical artifact Merlin has foreseen as the key to victory.
For Merlin, there are both good and bad consequences. On the bad side, some of the more traditional and anti - magic people in Camelot might try to oppose him. However, since Arthur now knows, he has a powerful ally. Arthur can protect Merlin from those who would do him harm. Also, Merlin can now be more open about using his magic for the good of Camelot, which is a positive change.
One interesting plotline could be their journey to discover their true family history. Since they are brothers in this fanfiction, there might be secrets about their parents or heritage that they uncover together. Another could be them facing challenges as brothers, like one getting into trouble and the other having to save him. For example, Arthur might get captured and Merlin uses his magic to rescue him, strengthening their bond as brothers in the process.
In some versions of this type of fanfiction, Arthur's reaction is complex. He might be stunned into silence when he first finds out. His mind would be racing with thoughts about all the times Merlin has used his magic to save him or Camelot without his knowledge. After the shock subsides, he may have a heart - to - heart with Merlin. They would talk about the implications of the secret, and Arthur would likely start to view Merlin in a whole new light, as not just his servant but as a powerful ally with a great burden.
It would likely become very strained. Arthur has been brought up to uphold his father's anti - magic stance. So, when Uther discovers Merlin's magic, Arthur might initially feel betrayed and distance himself from Merlin.
One common plotline could be Arthur realizing his roughness is wrong and trying to redeem himself. Another might be Merlin getting fed up and leaving, which then makes Arthur see how much he needs Merlin.
One common plotline is Merlin using his age - related wisdom to save Arthur from various threats. For instance, he might have prior knowledge of a magical curse that's about to befall Arthur and uses his experience to counter it.
One common plotline is Merlin using his youth to his advantage. For example, he might be able to blend in more easily with the younger generation in the kingdom, gathering information that Arthur can't. Another is Arthur having to deal with his own insecurities about getting older while Merlin is full of energy. Also, there could be a plotline where Merlin's younger age makes him more adaptable to new magic or technologies that are emerging, and Arthur has to rely on him for that knowledge.
