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.
I'm not really into promoting or discussing fanfic that has a sexual nature related to 'Eragon'. The 'Eragon' series is known for its fantasy elements, dragons, and a young hero's journey. There are much better aspects to explore in the official story rather than delving into inappropriate fan - made sexual content.
I'm not aware of any official or widely accepted 'Eragon' fanfic with sexual content. The 'Eragon' series focuses on adventure, magic, and fantasy elements, and most fan creations tend to stay within those themes rather than delving into inappropriate areas.
I'm not entirely sure specifically what that particular 'eragon lemon fanfic' is about. 'Lemon' in fanfic often refers to stories with some level of romantic or sexual innuendo, but without reading it, it's hard to say. 'Eragon' is from a series of books, so it might be a fan - created story that takes the Eragon universe and adds some uncanonical romantic or spicy elements.
Eragon himself is still very popular in fanfics. Writers often like to explore his character further, his growth, and his struggles. Saphira is also a favorite. Fanfic authors might write about her more independent adventures or her thoughts on different situations.
One idea could be a story where Eragon and Arya go on a quest together and encounter a magical lemon tree that has special powers. They have to protect the tree from an evil force that wants to use its power for bad.
Yes, there might be some out there. You can try looking on fanfiction websites. However, make sure to follow the site's rules and regulations. Some fanfics might deviate from the original story's tone or themes, but they can offer interesting new perspectives on the relationship between Eragon and Arya.
One interesting concept could be alternative endings for the story. Maybe in some fanfics, Eragon doesn't end up as a Dragon Rider in the same way as in the original. Another could be exploring different relationships between the characters. For example, how Eragon's friendship with Arya might develop in a different direction.
In a fanfic, Dark Naruto could team up with Eragon. Dark Naruto's combat skills and dark chakra could be combined with Eragon's dragon - riding and magic abilities. They could face challenges like an ancient evil that has been awakened and is causing chaos in both their realms. This would lead to interesting battles and character development as they learn from each other.
When writing a Dark Naruto and Eragon fanfic, think about the personalities of the characters. Dark Naruto is often brooding and powerful, while Eragon is brave and idealistic. You can use these traits to create interesting interactions. For the setting, decide if it will be mostly in the world of Eragon or if there will be some parts in Naruto's world too. Develop a story arc that involves a common goal for both characters, like saving a kidnapped dragon or stopping a dark wizard who has some connection to Naruto's enemies.
