It depends on personal taste. If you're a big fan of the Eragon series and love stories about dragons, it might be great. Some fanfictions are really well - written and capture the essence of the original story while adding new elements.
One common theme is friendship. The original characters often form strong bonds with the dragons, similar to the relationships in the original Eragon series. Another theme is self - discovery. As the oc interacts with the dragons, they learn more about themselves.
Obviously, Eragon himself is a main character, now in his dragon form. His dragon Saphira could also be a very important character. She might play a role in helping Eragon adjust to his new form, teaching him things about being a dragon that he doesn't know.
One possible plot could be that Eragon, while facing a powerful dark enemy, discovers a hidden ancient magic that causes him to transform into a dragon. As a dragon, he has to quickly adapt to his new form, learning to fly and use his newfound dragon abilities like enhanced strength and fire - breathing. He then uses these powers to defeat the enemy and protect his land.
The theme of loyalty is very prominent. They are extremely loyal to each other and this loyalty is tested in various situations in the fanfictions. Whether it's facing betrayal from others or difficult choices, their loyalty remains unwavering. This theme adds an emotional depth to the stories and makes their relationship even more endearing to the readers.
There could be many. One might be about a new adventure of Eragon and his dragon where they encounter a mysterious lemon - scented forest that has magical properties. It could involve them using the unique elements of this forest to overcome a new threat.
A more adventurous plotline could be Eragon as a dragon getting involved in battles on a much larger scale. He could use his new form to take on powerful enemies that were previously too difficult for him as a human. His dragon form might also attract the attention of other mythical creatures, leading to new alliances or rivalries.
No. The 'Eragon' series has a large following for its story of adventure, magic, and friendship. Adding sexual content through fanfic is not in line with the general tone and values of the fandom. It can also make many fans uncomfortable.
Start with a unique backstory. For example, if your OC was once a slave who escaped and then found a dragon egg. This kind of backstory gives the character depth and a motivation for their actions. They would be more than just a rider; they would be a survivor.
It can introduce new dragon realms. For example, a hidden world where dragons live in harmony, and Eragon, through his transformation, discovers this place. He could explore different terrains there, like floating islands or underground caves filled with magical crystals.
