The plot of the second season of the Lamia was as follows:
First episode:
The story took place in the modern world. It was about a wealthy family. Their family members fought fiercely for property and power. The main character, Bai Xiaochun, was a young lawyer who had come to work in the clan to help an old man resolve a dispute. In the process of solving the problem, he gradually understood the secrets of this family and discovered some unusual things.
Second episode:
This episode was mainly about a mysterious woman known as the " viper woman " who had a powerful magic power. The Lamia was once an ordinary person, but she was chosen by a mysterious force to become a mage. Her goal was to find a drug that could make her stronger. This drug was controlled by an evil force. By the end of the story, Bai Xiaochun and the viper-snake woman had worked together to find the medicine and thwart the evil forces.
Third episode:
This episode was mainly about an ancient family of mages. Their family members all had powerful magical abilities. The main character of the story, Bai Xiaochun, was just an ordinary lawyer, but he was unexpectedly drawn into the clan's secret. He discovered that his family members all had unusual abilities and their purpose was to protect his family's secrets, not for his own benefit. By the end of the story, Bai Xiaochun had successfully uncovered the clan's secret and foiled their conspiracy.
The fourth episode:
This episode was mainly about a mysterious city full of magic and mysterious powers. The main character of the story, Bai Xiaochun, arrived in this mysterious city and met a mysterious woman. This woman was known as "White Snake," and she was very powerful with magic. She had also helped Bai Xiaochun solve some of his problems. By the end of the story, Bai Xiaochun and the white snake had worked together to protect the mysterious city and stop the evil forces.
The main characters are obviously Lamia and Merlin. Lamia is often depicted as a unique and mysterious character with her own set of powers and abilities. She might have a connection to the more shadowy or less - known aspects of magic.
Some Lamia Merlin fanfictions might focus on their backstories. Perhaps a story that delves into how Lamia came to be in the magical realm and how she first met Merlin. It could be a tale of her being an outcast in her own world and Merlin being the one to offer her a place among the good magic - users, leading to a deep bond between them.
One idea could be a Lamia Girl who lives in a hidden forest and befriends a lost human adventurer. They help each other understand their different worlds.
One possible plotline could be that Harry discovers he has Lamia heritage. This could lead to him having different magical abilities related to Lamia, like the power to charm or hypnotize. He might face discrimination from some in the wizarding world who fear the unknown Lamia powers.
One possible plot could be that Harry is traveling and stumbles upon the Circus St. Louis. There, he encounters Lamia, who is a mysterious figure in the circus. Maybe Lamia has some special powers that Harry is intrigued by, and he decides to stay and learn more about her.
You can give her unique physical features like a special pattern on her scales or different colored eyes. For example, she could have eyes that change color depending on her mood.
There might be some out there. You could start by checking fanfiction websites like Archive of Our Own or FanFiction.net. Just search for those specific names and see what pops up.
I think it's quite unique. In the world of fanfiction, there are countless ideas, but making Harry Potter related to Lamia is not typical. Harry Potter has its own set of magical creatures and concepts, and Lamia is something different. It might attract those who are looking for something new and different in Harry Potter fanfictions.
