A third idea is a story where the Lady of the Lake sends Merlin on a quest. This quest could be related to saving the magical realm. Along the way, Merlin discovers secrets about the Lady of the Lake herself, such as her true origin or her connection to an ancient magic that has been long forgotten. This would add a layer of mystery to the story.
One idea could be that the Lady of the Lake gives Merlin a special power that he has to learn to control. For example, the power to control water in a way that no other sorcerer can. This could lead to him facing challenges as others might fear or envy this new ability.
One idea could be that the Lady of the Lake has a premonition about a great danger coming to Camelot and she enlists Merlin's help to prevent it. They have to go on a journey to find an ancient artifact that can save the kingdom.
Morgana could be a great antagonist. She might see the Lady of the Lake as a threat to her own power and plans for Camelot. And she could try to stop any alliance between Merlin and the Lady of the Lake.
One idea could be that Merlin somehow has a connection to the magic that the founders used to create Hogwarts. Maybe he left behind a hidden spell or prophecy that the founders discover while building the school.
Perhaps a story where Tiny Merlin accidentally shrinks the whole Camelot and has to figure out how to reverse the spell. He would have to use his wits and small - size advantages to solve the problem. This could involve sneaking into small spaces in the shrunken Camelot to find the source of the spell. It would be a really fun and adventurous story.
The relationship can be developed through shared secrets. For instance, if Merlin discovers a hidden prophecy that only the Lady of the Lake can help him understand. This would create a bond of trust between them as they work together to figure out the meaning of the prophecy.
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 in a moment of extreme danger, Merlin and Arthur share a kiss as a way of saying goodbye, not realizing they'll both survive. It could be a spur - of - the - moment, passionate kiss that catches them both by surprise. Later, they have to deal with the newfound feelings this kiss has unearthed.
One idea could be exploring the consequences if Merlin had been unable to find a cure for the poisoned chalice in time. Maybe Arthur's death would have led to a power struggle in Camelot, and Merlin would have to navigate through it while mourning his friend. Another plot could involve a twist where the poison was not what it seemed, and it was actually a magical test set by an ancient sorcerer to see if Merlin was worthy of his powers. The third idea might be that Merlin, in his desperation to save Arthur, makes a deal with a dark entity that has unforeseen and dangerous implications for Camelot in the long run.
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 interesting plot idea could be that when Shirou summons Merlin, Merlin initially seems uninterested in the Grail War but gradually gets involved to protect Shirou. He could use his magic to deceive the other Servants, creating illusions to mislead them about Shirou's true strength and intentions.
