Fanfiction about Merlin being Morgana's brother: What are some interesting plot ideas?

One idea could be that Merlin and Morgana, being immortal, witness the passage of time and the rise and fall of different kingdoms. They could have a sort of eternal rivalry, constantly trying to outwit each other in different historical periods. For example, in the modern era, they might compete for influence in the business world using their magical abilities in secret.

Well, a possible plot is that Morgana's pregnancy makes her re - evaluate her stance in the conflict. She might start to see things from a different perspective due to the life growing inside her. Merlin could be in a dilemma as he wants to support Morgana but also has his duties towards Arthur. The pregnancy could also bring out a softer side of Morgana that no one has seen before, and this change could be the key to some sort of peace in the land.

One plot idea could be Merlin reveals a long - hidden prophecy to Morgana that involves her true destiny. Another could be Merlin tells Morgana about a secret magical realm that only he knows of, and they embark on a journey to explore it. Or perhaps Merlin tells Morgana about his own insecurities and fears regarding his magic, which in turn makes Morgana open up about her own struggles.

One idea could be that Merlin teaches Morgana about the old magic in a secret grove. He shows her spells that can heal the land, and they bond over their shared connection to magic. Another could be Merlin teaching Morgana how to control her visions, which she's been struggling with. It could lead to a deeper understanding between them and a new alliance within Camelot.

One idea could be that their kiss is a moment of realization. Maybe they've been enemies or at odds for a long time, and the kiss makes them see each other in a new light. For example, Morgana realizes that Merlin's magic isn't as bad as she thought and that he has been trying to protect Camelot all along. Another plot could involve a magical bond that forms through the kiss. This bond could give them shared powers or make them telepathically linked, leading to some really interesting interactions as they learn to deal with this new connection. A third idea is that the kiss is a secret pact. They kiss to seal a deal to work together against a greater evil that threatens Camelot, but they have to keep their new alliance a secret from everyone else in the kingdom.

The child could be a bridge between the two opposing sides that Merlin and Morgana represent. The child's innocence and unique perspective could start to change the views of those around them, leading to a possible reconciliation between Merlin's side and Morgana's followers. This would involve a lot of character development for the child as well as for Merlin and Morgana as they see the world through the eyes of their offspring.

Perhaps Morgana ties up Merlin because she has been influenced by dark magic. In this scenario, Merlin has to use his wits and magic (secretly) to break free and also to break the spell on Morgana. It could lead to a journey of Morgana's redemption as Merlin shows her the error of her ways.

One idea could be that Harry discovers his connection to Morgana gradually. Maybe he starts having strange dreams related to her. As he digs deeper, he finds that some of his powers are actually linked to Morgana's magic, which sets him on a journey to understand more about his heritage and how it affects his role in the wizarding world.

A plot twist might be that the baby has some sort of prophetic power even before it's born. This power could show visions to Morgana or Merlin about the future of Camelot. It could also be that the pregnancy is part of a grander magical plan set in motion centuries ago by an ancient sorcerer, and Merlin and Morgana are just pawns in this plan, not realizing the true significance of the pregnancy until later events unfold.

One idea could be a story where they are rivals in a magical tournament. They have to compete against each other using their wits and magic skills, but in the end, they gain a mutual respect for one another. Another could be a story where they both get trapped in a magical realm and have to work together to escape, not as lovers but as comrades who need each other's skills.
