In some fanfictions, there might be a focus on the reactions of the common people to Aegon's arrival. For example, how the smallfolk in different regions either resist or embrace the new order that Aegon is bringing. This can add a whole new layer of depth to the conquest narrative as it shows the impact on the ground level.
One interesting plot twist could be that Aegon has a secret alliance with a powerful magical being that no one in Westeros suspects. This being could help him in unexpected ways during his conquest, like using magic to disable the defenses of a stronghold just before Aegon's forces arrive.
Perhaps a fanfiction where the magic in the conquest was more prominent. Instead of just using his dragons, Aegon has to also deal with powerful wizards and sorceresses from the different kingdoms. This would add a whole new dimension to the conquest story.
One interesting storyline could be a heroine who forms a unique bond with a rare Pokemon that no one else can tame. This special connection helps her in battles and also in uniting different regions in the Pokemon Conquest world.
In some fanfictions, Aegon I and Oc Targaryen could be involved in a love triangle. Maybe Oc Targaryen is in love with a noble from another house, but Aegon I wants her to marry someone for political reasons. This creates a complex web of emotions and political intrigue that could change the course of Targaryen history.
Rhaenys Targaryen is another significant character. Her charm and diplomatic skills could be highlighted in the fanfiction. She might be the one who tries to win over the hearts of the people in the kingdoms they are conquering. For example, she could use her beauty and grace to make alliances with some of the minor lords who are initially hesitant to side with Aegon.
Often, there are original characters who are advisors to Aegon. They might be seers or scholars who offer unique insights. These characters can be really popular as they add an element of mystery and wisdom to the story.
One interesting plot idea could be exploring Aegon's early days before his conquest. Maybe he has a secret love affair with a commoner that he has to keep hidden due to his family's expectations. This could add a layer of human vulnerability to his character.
Another could be a 'what if' scenario. Like what if a certain character got injured along the way and how it would change the dynamics of the group. This could involve exploring the relationships between the characters as they deal with the unexpected situation.
One interesting fanfiction could be where Aegon the Conqueror has to face an unexpected magical threat during his conquest. Maybe a powerful sorcerer tries to stop him by summoning dark creatures. This would add a new layer of danger and adventure to his already epic journey of uniting the Seven Kingdoms.
One plot idea could be that Arya and Aegon meet during their travels. Aegon, with his claim to the Iron Throne, is in need of a skilled ally like Arya. She could help him in his political maneuverings in a way that no one else can, using her skills of disguise and stealth. Another could be a story where they are forced to team up against a common enemy, like a new threat rising in the Seven Kingdoms that neither the Starks nor the Targaryens can face alone. They start off distrustful of each other but gradually come to respect and rely on one another.
