In siren short stories, the theme of the unknown is quite prevalent. Since sirens are often mysterious creatures, their existence and motives are part of the unknown. Mortality is also a common theme. The sirens' luring often results in the death of those who are attracted by their song. And there's the theme of transformation. Sometimes, characters who encounter sirens are changed in some way, either physically or mentally, after the encounter.
One common theme is temptation. The sirens' song is a form of temptation that leads characters into danger. Another is the power of beauty. Sirens are often described as extremely beautiful, and this beauty is used as a weapon. Also, there's the theme of survival. Characters in the story usually have to find a way to survive the encounter with the sirens.
One common theme could be the allure and mystery of the siren. In girlxgirl relationships in this context, the siren's powers might add an extra layer of intrigue. Another theme could be the exploration of forbidden love, as sirens are often seen as otherworldly and dangerous in many stories.
Another theme could be redemption. Black Siren might be on a path to redemption and Felicity could play a part in that journey. Their interactions in this context can be really interesting as Felicity tries to bring out the good in Black Siren. It could involve moments of self - discovery for both characters as they influence each other's growth.
One common theme is identity. Sirens often have to figure out who they are, especially when they are different from others. For example, in 'To Kill a Kingdom', the siren character has to redefine herself.
One common theme is the struggle between the siren's nature and the rules of the wizarding world. Sirens are often portrayed as having their own set of instincts that may conflict with the moral and ethical codes in Hogwarts.
Often, a common theme is the relationship aspect. Since she is a siren, she might attract various characters in the fanfic. There could be a love triangle or a complex relationship with other magical beings who are either drawn to her or afraid of her. Also, the idea of fem Harry being an outcast because of her siren nature is a theme. People in the wizarding world might not understand or might fear her, so she has to find her place among those who accept her for who she is.
Love and relationships are also big themes. A young adult siren might fall in love with a human, which goes against the norms of their species. This creates a lot of conflict and drama. There's also the theme of secrecy. Sirens usually have to keep their true nature hidden from the human world, which adds to the suspense and mystery in the story. It's like they are living a double life, and the fear of being discovered is always there.
A modern day siren story often has a character with an alluring voice. For example, like in the previous stories, the singers or the radio DJ had voices that could attract people. Another common element is an unexpected situation where the'siren - like' ability comes into play, such as the sailor being entranced while passing by the docks or the people in distress during the storm being soothed by the radio DJ's voice.
One common theme could be the struggle of Fem Harry with her new identity as a siren. Since sirens are often associated with allure and danger in mythology, she might have to deal with the way others perceive her. Another theme could be her relationship with other characters. For example, how her siren nature affects her friendships or potential romances. Also, the discovery and control of her siren powers could be a major theme, as she learns to use them for good or to protect herself in a world that may not understand or accept her.
I'm not entirely sure as I haven't read them specifically. But perhaps they could be about mystery and danger, given the word'siren' which often implies something alluring yet potentially perilous.
One common theme could be change. Since 'by and by' implies the passage of time, stories might focus on how characters or situations change over time. For example, a character might start off naive and become wise as the story progresses.
