Love and friendship are also common themes. Sirius may go back in time to save his friends or to rekindle relationships that were lost. He could try to save James Potter or ensure that he and Remus Lupin stay closer friends. These themes add an emotional depth to the time travel stories.
Another theme is exploration of the wizarding world's history. Sirius can travel to different points in time and we, as readers, get to see how the wizarding world has evolved. He might visit the time of the Goblin Rebellions or the early days of the Ministry of Magic. This allows for a deeper understanding of the world J.K. Rowling created.
One common theme is redemption. For example, in many fanfictions, Sirius gets a chance to go back and right some of the wrongs he may have felt he committed in his past. Another theme is self - discovery. As he travels through time, he learns more about himself and his place in the wizarding world.
The exploration of magic is a huge theme. Since it involves time travel near the veil, the fanfictions often dig into the more mysterious and powerful aspects of magic. How time travel magic works, what the veil has to do with it, and how it all affects the wizarding world. Also, the theme of self - discovery is there as characters learn more about themselves when faced with the challenges of time travel and interacting with Sirius in different time periods.
Love and sacrifice are also prevalent. Harry and Sirius' relationship deepens in these fics, and they often have to make sacrifices for each other during their time - traveling adventures. For example, Sirius might sacrifice his own safety to protect Harry in a different time era. And the theme of family is important too. They form a sort of family unit that is different from the traditional ones in the wizarding world.
One common theme is family. Since James is traveling through time, he often gets to meet his ancestors or relatives from different eras. This gives the author a chance to explore family relationships and how they shape the Potter family.
The theme of second chances is also prevalent. In time travel stories, both Harry and Sirius may get opportunities they missed in the original timeline. For example, Sirius could save his friends who died earlier. And also, the exploration of the past and how it shapes the future is a key theme. They go back and learn things that change their perspective on the present and future of the wizarding world.
One common theme is time - travel. Since there's a 'Time Queen' involved, the stories often play with the idea of Sirius Black traveling through time, either to change the past or to understand the future. Another theme is the power struggle. The Time Queen usually has some sort of powerful abilities related to time, and Sirius might be caught up in a struggle for power or against those who misuse the time - related powers.
One common theme is changing the past. Fans often write about characters trying to go back and fix things that went wrong in the original 'The 100' storyline. Another theme is the exploration of different time periods within the show's universe. This allows for new settings and character interactions.
A common theme is redemption. Both Snape and Sirius have complex pasts with many mistakes. Fanfictions often explore how they can redeem themselves in each other's eyes or in the eyes of the wizarding community.
One common theme is family conflict. Given that they come from the same family but have very different paths in life, fanfictions often explore how their family ties both bind and divide them. For example, the expectations of the Black family and how they each rebel against or conform to those in different ways.
Another theme is family. Since Harry lacks a proper family, Sirius becomes like family to him. Fanfictions explore how they create a family - like bond in the absence of Harry's real family. It can be really emotional.
