One common theme is self - discovery. Since Clary is a Nephilim, she often has to figure out her place in the Shadowhunter world, her powers, and her identity. Another theme is love and relationships. Her relationships with other Shadowhunters, like Jace, are often explored in different ways in fanfics.
Power struggles are also a frequent theme. As a Nephilim, Clary has power, but she also has to deal with those who may want to use her power for their own gain or those who are jealous of her. And of course, the theme of family is important. Clary's family situation, both her biological family and her found family among the Shadowhunters, is often a big part of these fanfics.
One common theme is their forbidden love. Since they are Shadowhunters with certain rules and taboos in their world, their love often goes against some norms, which makes for a very intense and passionate story.
One great Clary Nephilim fanfic is 'The Ascension of Clary'. It really delves into her character development as a Nephilim in a unique way. The author beautifully describes her journey, her struggles with her new powers and her relationships within the Shadowhunter world.
Love and attraction are common themes. Since it's about Clary seducing Jace, there's a lot of focus on their growing feelings for each other. Another theme could be the power dynamics, as Clary tries to take the initiative in the relationship.
Power is a common theme. All three characters possess certain powers in the Shadowhunter world. Fanfics often explore how they use or misuse their powers, and how power affects their relationships. For example, Sebastian's quest for power might put him at odds with Clary and Jace. Also, the theme of family is present. Clary's connection to both Jace and Sebastian in different ways ties into the idea of family, whether it's a found family or a biological one.
You could try looking for fanfics that focus on other powerful female characters in the nephilim or supernatural genre. Some might be about a character who has a similar origin story or power set.
One common theme is the struggle between good and evil. Since nephilim are often part - angel, they are usually on the side of good but have to face various evil forces. Another theme is identity. Nephilim are not fully human or fully angel, so they often struggle with who they are.
One common theme could be the character's journey towards recovery. It might show Clary's internal battles with self - acceptance and body image.
Identity is another big theme. Nephilim are a unique blend of human and angel. Fanfictions often show them trying to figure out where they belong. Are they more human or more angel? And how do they fit into the world of the supernatural which has its own rules and hierarchies? This exploration of identity can be really interesting and complex.
Another theme is the clash between the wizarding world and the Nephilim world. There are usually differences in their cultures and ways of using magic, which can create conflict or cooperation depending on the story. For example, in some fanfictions, the two worlds must work together to defeat a greater evil. This theme allows for exploration of different magic systems and world - building. In addition, the theme of identity is also prevalent. Harry has to figure out how being part of the Nephilim affects his identity as a wizard and as a person.
One common theme is the forbidden love. Since nephilim are often seen as a unique and sometimes dangerous or otherworldly beings, their relationships with humans or other beings are usually frowned upon in the story's world, which adds to the allure of the romance.
