A third common theme is the discovery of lost magic. Since they are in a different time, they might come across magic that has been forgotten in their own time. This could range from ancient spells to magical artifacts. It adds an element of mystery and adventure to the fanfictions as they try to understand and use this lost magic.
The exploration of destiny is also a frequent theme. Time travel often makes them question whether their future was already set or if they can change it. For example, they may wonder if they were always meant to be together or if their actions in the past can lead to a different outcome. Additionally, the power dynamics in the wizarding world can be a theme. With time travel, they may have an opportunity to change the power structure, and this can be related to their relationship as well.
Friendship is a very common theme. Writers often explore how Harry, Hermione, and Daphne can form a strong bond despite their different backgrounds. For example, Harry being the Boy Who Lived, Hermione the Muggle - born genius, and Daphne from a different pure - blood family.
Well, I really like 'The Time - Warped Love of Harry and Daphne'. In this fanfiction, the time travel aspect is used to bring Harry and Daphne together in unexpected ways. Their journey through time not only changes their own fates but also has an impact on the wizarding world as a whole. Also, 'Harry, Daphne and the Time Loop' is quite engaging. It's about them getting stuck in a time loop and how they figure out a way to break free while falling in love. Then there's 'Time - Shifting Harry and Daphne' which has a great take on how they use time travel to solve mysteries.
One common theme is self - discovery. When they travel through time, they often learn more about themselves. For example, in many stories, Hermione discovers new aspects of her courage outside of just academic achievements. Another theme is the impact of small changes. A small action in the past or future can have a big ripple effect on the wizarding world, which is often explored.
One common theme is redemption. Often, time travel gives Narcissa a chance to change her actions in the past, especially regarding her loyalty to Voldemort. Another theme is forbidden love. Since Harry and Narcissa are from different sides in the original story, time travel allows for a different exploration of their relationship that was not possible in the normal timeline.
One common plot device is the need to fix something in the past. For example, preventing a dark wizard from getting a powerful artifact that later causes trouble in their time. It creates a sense of purpose for their time - traveling adventure.
A common theme is self - discovery. Hermione, as a werewolf in a time - travel setting, often has to figure out who she is in this new context. Another theme is the struggle against prejudice. Since werewolves are often stigmatized in the wizarding world, Hermione has to deal with that while also navigating through time.
One common theme is fixing past mistakes. Since they can travel through time, often they try to correct things that went wrong in the original timeline, like saving a character who died prematurely.
One common theme is changing the past. Fans often write about Hermione using her knowledge to fix things that went wrong in the original story, like preventing certain deaths or stopping Voldemort earlier.
There's 'Soul - Bound Time Travelers: Harry and Daphne'. Here, the soul bond gives them special powers during their time travel. They can communicate telepathically across time, which helps them solve mysteries in the past and also change some future events that were not in their favor. The author does a great job of exploring the implications of their bond in different time periods.
