Another interesting aspect could be creating new elven sub - races within the 'Throne of Elves' universe. You could describe their unique cultures, abilities, and how they interact with the main elven society.
One great fanfiction could be about a young hero's journey in the world of Dragon Nest Throne of Elves. They might start as a novice adventurer, facing the challenges of the elven realm. Maybe they discover a hidden power within the throne that changes their destiny.
First, familiarize yourself with the original 'Throne of Elves' material. Read it carefully to understand the world, the characters, and the overall tone.
The theme of redemption is quite popular. For example, a character who has made mistakes in the past tries to make amends by protecting the throne of elves. It adds depth to the character's arc.
I recommend Kingdom Bloodline. This novel told the story of Thales, a beggar who became a prince of dark elves. His elder brother was a traditional Light Elf who inherited the throne, and he faced all kinds of difficulties and obstacles, eventually becoming the glory of the empire. I hope you like my recommendation. Muah ~
There might be a young and adventurous elf who becomes Harry's friend. This elf could be named something like Lyra. She could show Harry all the secret places in the elven territory and introduce him to other elves. There could also be a powerful elf leader, perhaps named Thranduil, who at first is suspicious of Harry but later comes to respect him.
Winky is also a popular choice. Fanfiction might focus on her recovery from her problems in the original series, like her addiction to Butterbeer. Maybe she becomes a strong advocate for elf rights in these stories.
Dobby would likely be one of the important house elves. He has shown great courage and a willingness to go against the norm to help Harry in the original series. In this fanfiction, he could be the leader among the house elves in the rescue mission.
Dobby is often very popular in fanfiction. Since he was already a well - developed character in the original series, fanfiction writers like to expand on his story further. He might be shown having more adventures or getting into different kinds of trouble. Another popular one is Kreacher. Writers may explore his complex personality more deeply, perhaps showing a side of him that was not fully explored in the books, like his loyalty to the Black family in new and interesting ways.
Typically, the dark elves are shown as powerful. They have advanced magic skills that they use to capture and control the human. They may be seen as cruel, especially in the beginning when they first capture the human. But sometimes, they are also shown as having a complex moral code. So while they might be doing bad things like capturing the human, they might also have reasons like protecting their own kind or following an ancient prophecy.
