One common theme is the struggle of the single mom in a world that might not fully understand her situation, especially in the context of King Arthur's time. Another theme could be the relationship between the reader (the single mom) and King Arthur, perhaps how he helps her overcome difficulties.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). It has a vast collection of fanfics, and you can simply search for 'King Arthur x Single Mom Reader' in the search bar. Another option is Fanfiction.net, which also has a large number of fan - created stories.
One idea could be a story where the single mom pregnant reader meets a kind-hearted stranger who offers unexpected support. Maybe at a local grocery store, this stranger helps her carry her groceries and they strike up a conversation that gradually develops into a beautiful friendship that helps her through her pregnancy.
For a realistic relationship development, it should start with Thanatos observing the single mom in her daily life. He could notice how she takes care of her child, manages the household, and faces difficulties. This initial interest can then turn into a deeper emotional connection as he starts to understand her emotions and motives. They could start with small interactions, like Thanatos leaving small signs of his presence that the single mom gradually realizes are from someone or something otherworldly.
Perhaps the single mom has lost someone dear to her and Thanatos, being associated with death, has a connection to that loss. He is drawn to her grief and her love for her family. He tries to comfort her in his own way, and as they interact more, a relationship forms. They might go on adventures together where Thanatos shows her different aspects of the afterlife, which helps her come to terms with her loss and also fall for him.
Love and support is another theme. Whether it's the love from her family, a new friend, or even a potential romantic interest, this love and support helps her through the tough times. It could be a neighbor who offers to babysit in the future or a co - worker who gives her extra shifts to earn more money for the baby.
The contrast between the two concepts. Lucifer is often depicted as this complex, otherworldly character, and a single mom represents a very down - to - earth, relatable figure. The clash and potential for interaction between them can create unique and engaging storylines.
Writers can develop the single mom's character by showing her strength. She has to manage on her own while taking care of her child, so depicting her as a capable and resourceful woman is important. For example, she could be shown handling financial difficulties with ease. Also, her love for her child should be a central aspect, like how she sacrifices her own needs for the child's well - being.
One popular theme is adventure. Arthur Morgan is often involved in various adventures in the game world, and in fanfiction, the reader can be part of those exciting escapades. Another theme is redemption. His complex character allows for stories where the reader helps him find redemption or he helps the reader in their own journey of self - discovery. And of course, there's the theme of romance, which is central to the 'arthur morgan x reader' concept, with different levels of intimacy and emotional connection being explored.
The theme of hope is also prevalent. Despite the difficulties of being a single mom and being pregnant, there's always a sense of hope in these fanfics. Whether it's hope for a better future for the baby, or hope that the mom - the reader - will find true love or a stable life. It gives the story an uplifting feeling, like there's always a light at the end of the tunnel no matter how dark it seems.
