Another plotline might involve how the society in Alagaësia reacts to Eragon having two dragons. Traditionally, dragon riders have only one dragon, so this could cause jealousy among other riders or even fear among the general population. It could lead to political unrest and Eragon having to navigate a very complex social situation.
Perhaps in the fanfiction, the two dragons have different personalities. One could be more aggressive and the other more cautious. This causes Eragon to have to balance their natures while training them, leading to a whole new set of challenges and character development for him.
Well, Eragon is obviously one of the main characters as the title implies he has two dragons. His two dragons would also be important characters. They would have their own identities and characteristics that play a big role in the story.
Another theme is identity. The dragon blood makes Eragon different from others. Fanfictions may focus on how he struggles to come to terms with this unique part of himself, like in stories where he tries to hide his dragon - blood - related traits in a normal human society within Alagaësia.
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.
One idea could be that Eragon discovers unique dragon magic only accessible to those raised by dragons. For example, he might be able to communicate with all dragons on a deeper level, not just his own. Another plot could involve him facing challenges from dragon - haters who fear his special bond with the dragons. They might try to break the bond or harm him.
One common plotline could be Jon Snow using the dragons to unite the Seven Kingdoms. He might ride the largest dragon and intimidate his enemies into submission. Another plotline could involve Jon Snow forming a special bond with the dragons, similar to how Daenerys did. This bond could give him unique powers or insights.
One possible plotline could be how Harry deals with the different parenting styles of his two fathers. For example, one might be strict about magic studies while the other is more lenient, creating a dynamic where Harry has to navigate between them.
One interesting plotline could be the rebirth of a powerful dragon with amnesia, having to rediscover its powers and past. Another might involve the dragon's new relationships with other mythical creatures in the fanfiction world.
Well, I've also come across 'Dragon Blood's Influence' which is a really engaging fanfiction. It focuses on how Eragon's dragon blood is not just a source of power but also a curse in some ways. It explores his internal struggle with this power and how it changes his relationships with those around him.
One interesting plotline could be Natsu's struggle to fit in with human society after being raised by dragons. He might have different values and ways of doing things that clash with humans.
One interesting plotline could be the discovery of a new type of dragon with unique abilities. For example, a dragon that can change its color to blend into different environments, which adds a new layer of strategy in battles and hiding from enemies.
