In these fanfictions, the theme of mystery is quite prevalent. The nature of the Time Queen herself is often a mystery. Is she a benevolent force or something more sinister? Sirius Black is then drawn into this mystery, trying to figure out her true intentions. Also, the idea of alternate timelines is a common theme. The Time Queen's power might create or access alternate timelines, and Sirius has to deal with the consequences of these different realities.
A major theme is the relationship between Sirius Black and the Time Queen. It could be a romantic relationship, where they navigate the challenges of different powers and timelines together. There's also the theme of destiny. The fanfictions often explore whether Sirius' encounter with the Time Queen is part of a greater destiny, whether for good or for bad. And of course, magic is a big theme as well, with all the time - based magic and other spells that are part 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 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 theme of freedom is quite important too. Sirius was locked up in Azkaban for a long time, and when he escaped, he was fighting for his freedom. Fanfictions often expand on this, showing his journey to fully regain his freedom and his place in the wizarding world, while also dealing with the prejudice against him because of his supposed crimes.
The theme of redemption also shows up. Since Sirius had a somewhat 'tainted' reputation in the eyes of the Black family, some fanfictions explore if Orion could have played a role in his redemption or if Sirius could have redeemed the family name in Orion's eyes.
One common theme is the vulnerability of Sirius. Usually, he's portrayed as this strong, brave character, but when sick, he shows a different side. Another theme is the support from his friends and family. They often rally around him, highlighting the importance of those relationships.
One common theme is family conflict. Sirius rebels against the pure - blood mania and dark magic - associated ways of the Black family that Walburga represents. Another theme is the struggle for identity. Sirius is trying to be his own person away from the expectations set by his family with Walburga as a symbol of those family constraints.
One common theme is love. Often, the female character falls in love with Sirius Black, exploring the different aspects of romantic relationships in the wizarding world. For example, how they deal with the danger he's in and the secrecy required in their relationship.
One common theme is loyalty. Sirius was extremely loyal to his friends, and fanfictions often explore this aspect in different situations, like when he was in Azkaban but still held onto his love for James and his friends.
One common theme is unrequited love. Sirius might be jealous because he loves someone who doesn't seem to return his feelings in the same way. For example, he could be jealous of someone else getting closer to the person he has feelings for.
A prevalent theme is the exploration of relationships. His relationships with his friends, like Remus and James (in flashbacks or through memories), are re - examined. How they support or sometimes struggle to support him is a big part of these fanfictions. Also, the relationship with the potential father of the child (if it's part of the story) is often a central focus, full of drama, love, and sometimes conflict.
One common theme is family. Since Sirius comes from the Black family, stories often explore how his child is related to the family's complex history, traditions, and dark secrets.
