One great Merthur lemon fanfic is 'A Touch of Magic'. It beautifully weaves the relationship between Merlin and Arthur in a rather intense and romantic way. The story has a great build - up of their emotions.
There's also 'Merlin's Secret'. This fanfic focuses on Merlin having to keep his magic a secret from Arthur in a more complex way than in the original show. It has a lot of tension and the relationship between the two is portrayed in a very interesting and heart - warming manner.
There are quite a few well - known ones. One is 'TheDragonLover'. Their stories often have great character development and unique plot twists. Another is 'MagicInTheAir' who is good at creating a vivid and immersive world for Merthur's relationship. And 'HeartOfCamelot' also writes some really engaging Merthur lemon fanfiction.
I really like 'Merthur's A/B/O Destiny'. It delves deep into how the A/B/O elements affect their world and their connection. It has some really interesting plot twists that add to the overall charm of the fic. For example, the way Merlin's omega nature is intertwined with his magic in this story is quite creative.
Love and passion are very common themes. Since it's a 'lemon' fanfic, there's often a focus on the physical aspect of their relationship, but also the deep emotional connection between Merlin and Arthur.
One great piece of merthur crossover fanfiction is 'The Adventure Beyond Realms'. It combines the world of Merlin and Arthur with elements from other fantasy universes, creating a really exciting and unique story. The characters are well - developed, staying true to their original personalities while also adapting to the new situations in the crossover.
Well, 'The Married Life of Merthur' is a really interesting one. It shows how Merlin uses his magic in a discreet way to support Arthur as his husband. It also has some really sweet domestic scenes, like Merlin cooking for Arthur and them having quiet evenings together. There's also 'Merthur: Ever After' where they face challenges together as a married couple and their love just grows stronger through it all.
There's also 'Emrys' Unseen Powers'. This fanfiction delves into Merlin's magical abilities as Emrys in a way that's really engaging. It shows how his powers can both help and complicate his relationship with Arthur. It's full of action and mystery, which makes it a really exciting read.
A common theme is the overcoming of obstacles. Since their relationship has many barriers in the show, like Arthur's initial ignorance of Merlin's magic and the social differences between them, fanfiction often focuses on how they break through these. Also, there's the theme of adventure. Writers might send them on new quests together, building their bond in the process.
One common theme is friendship. Merlin and Arthur's deep friendship is often explored further, showing how they support each other through tough times. Another theme is sacrifice. Since they both have important roles, they often have to make sacrifices for the greater good, which is a big part of many fanfics.
I'm not sure specifically which 'dawn lemon fanfic' is good. You could try searching on some popular fanfic websites like Archive of Our Own. They usually have a wide range of fanfics and might have some related to 'dawn lemon' that other readers have rated highly.
