There are several important characters. Arya is an elf who plays a significant role in the story. She has her own goals and is involved in many of the events. Murtagh is a complex character. He has a connection to Eragon and his actions impact the story in many ways. And Galbatorix, the main antagonist, is very important as he is the source of much of the conflict in the novel.
Well, the main themes are quite diverse. There is a sense of destiny in the novel. Eragon seems to be fated for certain things, and this theme adds an air of mystery. Then there is the theme of loyalty. Characters show loyalty to their causes and to each other. The theme of growth is also there. Eragon starts as a simple farm boy and gradually transforms into a powerful figure, both in terms of his skills and his understanding of the world.
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.
In the official Eragon lore, we have epic battles, the bond between dragon and rider, and the exploration of a richly detailed fantasy world. But any form of sex stories are completely absent. The series is aimed at a wide range of audiences, including young readers, so it adheres to a certain standard of propriety.
Saphira is often a popular character. Since she is Eragon's dragon, she can add a lot of depth to the story. Her unique abilities and her relationship with Eragon can influence the interactions between Eragon and Murtagh in the fanfiction.
The OC could be integrated into the story by having a shared past with either Eragon or Murtagh. Maybe they grew up in the same village as Eragon but were separated when the Ra'zac attacked. Years later, they reunite and the OC can offer some unique perspective or ability to the situation. Or, if the OC has a connection to the dragons in a different way than Eragon and Murtagh. For instance, the OC might have a special bond with a dragon that was thought to be lost. This would bring them into the story as they try to protect their dragon friend and get involved in the events related to Eragon and Murtagh. Also, the OC could be a trader who has information about the movements of the enemy forces. They could trade this information to Eragon and Murtagh in exchange for protection or some other favor, thus becoming part of the story.
Yes, there are many appropriate 'Eragon' fanfics. These often explore aspects such as different adventures for Eragon and his dragon Saphira, or new storylines within the world of Alagaƫsia. For example, some fanfics might focus on how Eragon interacts with other races in the land, like the dwarves or the elves, in a way that is true to the original world - building of the series.
Definitely not. The Eragon series is all about the hero's journey, his relationship with his dragon, and the fight against evil. There is no official narrative that includes sexual content.
