Well, it might lead to him being ostracized in some communities. Since he can't hide his magic, in a society where magic is feared or not fully accepted, people could shun him. This would make it difficult for him to have a normal life among non - magic folk. Also, it could potentially expose Arthur, his friend, to unnecessary risks as his association with Merlin becomes more obvious.
His inability to hide his magic well could cause problems within Camelot's court. The more his magic is evident, the more likely it is that there will be those in the court who will try to use it against him or Arthur. There could be political intrigue as some may see Merlin's magic as a threat to the status quo. His lack of control over hiding his magic could also make it harder for him to secretly use his magic to protect Arthur, as he might be discovered mid - spell.
In fanfiction, if Merlin can't hide his magic, it could lead to a lot of exciting plot developments. Maybe it means his magic is too powerful or he's in a situation where he can't control it. For example, in some stories, he might be under a spell that makes his magic visible, which could put him in danger as magic is often feared in the Merlin universe.
Merlin could face exile. Uther may not tolerate having a magic - user so close to him.
It's interesting because it goes against the usual secrecy around Merlin's magic in the original story. It adds a new layer of drama and suspense. His inability to hide his magic can create all sorts of situations where he has to deal with the consequences, like facing those who fear or envy his power.
He could face Morgana's distrust if she takes his secrecy the wrong way. Maybe she'll think he has other motives for hiding his magic from her.
She might be shocked at first. Given that in the original story Morgana has her own complex relationship with magic, seeing Merlin's magic could stir a mix of emotions in her, like envy or a sense of relief that she's not alone in her magical abilities.
It might make his relationship with Arthur more complex. Arthur, who has been raised to be cautious of magic, might have mixed feelings. On one hand, he trusts Merlin, but on the other, Merlin's exposed magic could make Arthur question things. With Gwen, she might be more accepting, but still worried about the potential danger it brings to Merlin. And with the other knights, some might be more superstitious and keep their distance, while others might be curious and want to learn more about his magic.
One popular one might be 'The Unveiling of Merlin's Magic' where Merlin reveals his powers in a dramatic showdown. It has great character development and a thrilling plot.
One possibility is that Merlin's revelation of his magic could lead to a change in his relationships. For example, his friends who were previously unaware might react with shock, some with fear and some with acceptance. His enemies, on the other hand, would likely see him as an even greater threat and might plot more vigorously against him.
One great 'Merlin Magic Incarnate' fanfiction could be 'The Ascent of Merlin'. It explores Merlin's journey as he fully embraces his magic in a new and exciting way. Another is 'Merlin's Hidden Powers' which delves deep into his magic incarnate form and the challenges he faces. There's also 'Magic Unleashed: Merlin's Destiny' that takes the concept and creates a thrilling adventure around it.
In this type of fanfiction, the world - building around Merlin's magic can be a major draw. Writers might create new magical creatures or spells that are connected to Merlin's essence as magic. They could also explore how Merlin's magic interacts with the existing magic in the Arthurian legend, like the magic of the sorcerers, druids, and Morgana. This can add a whole new layer of complexity and intrigue to the familiar Arthurian setting.
