Another place could be Fanfiction.net. There are many Twilight - related fanfictions there as well. However, the quality may vary, so you might need to read the summaries and reviews to find the good ones about Edward and Carlisle.
One interesting story could be about their early days together. Maybe it focuses on how Carlisle turned Edward and the initial struggles Edward faced adjusting to his new vampire life. It could show Carlisle guiding him through the process of controlling his thirst.
Characterization is key. A good Carlisle Cullen x OC fanfiction should have a well - developed OC. The OC should have unique traits, not just be a generic character. For example, if the OC has a special ability or a distinct personality that interacts interestingly with Carlisle's calm and noble nature. Also, the relationship between them should develop realistically. It can't be love at first sight without any proper build - up. They should have shared experiences, conversations, and challenges that bring them closer together.
I would recommend 'A New Beginning for Bella and Edward'. This fanfic takes their story in a different direction after the events in the original series. It shows how they handle new challenges together and the growth of their love in the face of those difficulties. There are some really beautiful and heart - warming moments in it.
They are popular because their relationship is so unique. Edward is Renesmee's father in a very unconventional vampire - half - vampire family dynamic. Writers like to explore this complex bond.
I also like 'The Healer's Touch'. In this fanfiction, Carlisle uses his medical skills not just to heal Bella physically but also to help her through some emotional traumas. It's a heart - warming story that shows a side of their relationship that we don't often see in the original series. It's full of tender moments between them.
In a fanfiction, Carlisle Cullen might meet a vampire from a different coven. This vampire has a very different view on life compared to Carlisle. They initially clash but as they get to know each other more, Carlisle starts to see the world in a new light. Their love story could be about how they overcome their differences, like her more carefree attitude towards human blood in contrast to Carlisle's strict self - control, and find love in each other.
One aspect of Carlisle Cullen x Bella fanfiction could be the exploration of their unique relationship within the Twilight universe. Carlisle is an old and wise vampire, while Bella is a young human. Fanfictions might delve into how Carlisle's self - control and moral code interact with his growing feelings for Bella. It could also show how Bella views Carlisle in a different light compared to Edward, perhaps seeing him more as a father figure or a source of guidance at first, and then developing more complex emotions.
One great Edward and Carlisle fanfiction is 'The Bond Beyond Blood'. It delves deep into their relationship, exploring how Carlisle's wisdom influences Edward. Another is 'A Father's Guidance' which focuses on Carlisle's role as a father figure to Edward in different scenarios that are not in the original story.
In some fanfictions, the relationship between Kagome and Edward is developed in a very slow - burn way. They start as curious about each other's differences. Kagome is intrigued by the vampire world and Edward is fascinated by her spiritual abilities. These stories often explore themes of love across different species and cultures, making for a really engaging read.
There's also 'Carlisle's Perspective'. This fanfiction delves into Carlisle's thoughts and feelings regarding Bella. It gives a fresh take on their relationship, showing how Carlisle might view Bella's presence in their family in a more in - depth way. It has some really interesting plot twists as well.
