Often, these fanfictions explore the concept of domesticity. They show Harry and Astoria creating a home together, which is a big change for Harry who has had a rather tumultuous life. There are also themes of friendship within the context of their marriage. How their friends react to their union and how they support or sometimes complicate their relationship. It's also common to see themes related to the magical world's politics and how their marriage might be affected by it.
The clash of house cultures is also common. Astoria being from Slytherin and Harry from Gryffindor, there are often stories about how they bridge the gap between the two houses' values and traditions. It makes for an interesting dynamic as they learn from each other.
One common theme is redemption. Draco was a bit of a bully in the original series, and in these fanfictions, his marriage to Astoria is often part of his journey towards becoming a better person.
Redemption is also a theme sometimes. Astoria might be seen as a way for Harry to find a more peaceful life after all the chaos of his past. Growth and self - discovery are in there too. As they get to know each other, they both grow as individuals. For example, Harry might learn more about the wizarding society's subtleties through Astoria.
One common theme is friendship. Writers often explore how Harry could form new friendships with Daphne, Tracey, and Astoria outside of his usual circle. Another theme could be adventure, like they all embark on a quest together.
One common theme is family loyalty. Since the Greengrass family is an important part of the wizarding world in these fanfictions, loyalty within the family, like between Daphne and Astoria, is often explored. For example, in some stories, they might support each other through difficult times at Hogwarts.
Another theme is the exploration of different magical abilities. Each character may have their own unique skills, and in fanfiction, these can be highlighted. Astoria might have a particular gift for potions that she shares with the group, leading to various adventures and problem - solving situations. Also, love and relationships play a part. Harry and Ginny's relationship can be further developed, and how Astoria and Gabby fit into their world in terms of the romantic and platonic relationships.
One common theme is love. Often, it's about Astoria's relationship with Draco, showing how they fall in love and deal with the post - war wizarding world together. Another theme is family. Since she's from the Greengrass family, her family heritage and the expectations that come with it are explored.
The theme of change is also quite prevalent. Harry's married life means a new phase in his life. His values, his relationships with his friends, and his approach to magic might all change. Fanfictions often show how he adapts to these changes and how his new life affects those around him. For example, his friends might have different expectations of him now that he's married, and the fanfiction could explore how he manages those expectations while still staying true to himself.
One common theme is the adjustment to domestic life. Harry, who has been through so much adventure, now has to adapt to a more normal, married life. Another theme is how his marriage affects his relationships with his friends, like Ron and Hermione. Sometimes it can create a bit of distance as he focuses on his new family.
Friendship is a common theme. They could all start as strangers from different backgrounds in the wizarding world but gradually form a strong bond. For instance, Harry from his Gryffindor side and Daphne from Slytherin might overcome house differences.
