A new villain could be introduced in the fanfic who is specifically out to get Connor Kenway. This villain might have a personal grudge against Connor or be on a mission to eliminate all the Assassins, and Connor becomes their prime target and ultimately falls to their schemes.
Another scenario might be that Connor Kenway succumbs to an illness or injury that he has been secretly carrying. He tries to keep it hidden as he continues his duties as an assassin, but in the end, it becomes too much and he passes away, leaving a legacy behind in the Assassin's Creed Brotherhood.
In a fanfic, they could be part of a grand adventure across the colonies. They get caught up in a mystery that involves ancient artifacts. Connor's knowledge of the land and his tracking skills, along with Aveline's ability to blend in and gather information in urban areas, would make for an exciting story as they race against time to uncover the secrets of the artifacts and keep them out of the wrong hands.
Begin by creating a conflict that involves both Edward and Connor. It could be a new Templar threat that has roots in Edward's time and resurfaces in Connor's. Develop their characters further by giving them internal struggles. Maybe Edward is haunted by his past actions as a pirate, and Connor is struggling with his identity as an Assassin in a changing world. As you write, keep the pacing right. Alternate between action - packed scenes and more reflective moments. And most importantly, let your love for the Assassin's Creed series shine through in your writing.
One great Connor Kenway fanfiction is 'The Hidden Path'. It delves deep into Connor's character, exploring his internal struggles as he tries to protect his tribe and the colonies. Another one could be 'Connor's Redemption', which shows a different side of his journey, focusing on how he copes with the consequences of his actions. And 'Connor Among the Ancients' is also interesting as it places Connor in various historical and mythical situations.
A fanfiction could be about family ties. Maybe Connor discovers he has a distant relative who was part of Edward's crew. He sets out to find this person and in the process, uncovers more about his family's past. Along the way, he meets Edward's ghost or some kind of spiritual manifestation of him. Together, they work to protect a hidden Assassin stronghold from the encroaching Templars.
One possible plot could be that Connor, being from a later time in the Assassin's Creed timeline, stumbles upon some ancient records or a hidden memory that leads him to Edward. They might initially be at odds due to their different time periods' ways of life. Edward, being more of a swashbuckling pirate - assassin, could teach Connor some new combat techniques or ways of navigating the high seas that Connor hadn't experienced in his mainly land - based adventures. They could also bond over their shared goal of fighting the Templars, with Edward sharing his experiences from the earlier days of the conflict and Connor bringing in his knowledge of the more evolved Templar plans in his time.
Sure. A lot of fanfiction writers like to create their own unique takes on established characters. In the case of a female Connor Kenway, you could find fanfictions that give her new adventures. For example, she might have different interactions with the Templars or other Assassins. Check out fanfiction.net as well, as it has a large collection of fan - made stories.
