One interesting concept could be the change in relationships. For example, characters who were enemies in the original series might form unexpected alliances in this fanfiction. Another could be the alteration of magical abilities. Maybe a character discovers a new and unique magical power that changes the power dynamics in the wizarding world.
It could introduce new original characters that are central to the story. Maybe a young witch or wizard from a foreign wizarding school who comes to Hogwarts and has a major impact on the events in the fanfic. This new character could bring different magical abilities and cultural elements from their own school into the Hogwarts environment, causing all kinds of changes.
In Harry Potter fanfiction, time can change everything by allowing characters to grow and develop. For example, as years pass, young wizards become more powerful and experienced. Their relationships also evolve. Friends might become enemies or vice versa over time. The wizarding world itself can change, with new spells, creatures, or political situations emerging as time goes on.
It stands out because of its unique take on change. Most fanfictions might just tweak a few details, but this one seems to be centered around the idea of everything being different. So it can offer a completely fresh perspective on the Harry Potter universe.
In this fanfic, there could be a plot twist where the Hogwarts houses' traditional rivalries are turned on their heads. Instead of Gryffindor vs Slytherin, etc., a new threat makes them all have to work together in ways they never expected. The characters might have to overcome their long - held prejudices and form new relationships to face this common danger, which is a big change from the norm in the Harry Potter universe.
One example could be the change in Hogwarts over time. Maybe in some fanfictions, with the passage of years, the layout of the school changes, new rooms are discovered. Another example is the relationship between characters. Harry and Draco might start as bitter enemies, but as time passes in the fanfiction, they could become reluctant allies. Also, time could change the power dynamics in the wizarding world. A small, insignificant family could rise to power over time.
One good small change could be in the character development. For example, Neville could start showing his courage a bit earlier in the fanfiction. This would add an interesting twist as it would make the story deviate slightly from the original in a positive way. It could also change the dynamics within the group of friends at Hogwarts.
One interesting concept could be the butterfly effect. When a character travels through time, even a small change can lead to huge differences in the future. For example, a simple decision like stopping someone from getting on a bus can change the course of many lives. Another concept is the alteration of relationships. Time travel might make characters meet in different circumstances, changing their entire dynamic. Maybe a friendship that was strong in the original timeline becomes a rivalry due to time - travel - induced changes.
It can change their personalities. For example, if a character goes through a traumatic event in the past during time travel, they might become more cautious or even cynical in the present. They've seen the darker side of things and it affects who they are.
In fanfiction, 'Harry Potter changes Westeros' could be through his magic skills. For example, his spells like Wingardium Leviosa could be used to move heavy objects in Westeros, which might change the way battles are fought or construction is done. His knowledge of the magical world could also introduce new concepts to the people of Westeros.
