I really like 'Crossing Realms: Mortal Instruments in Hogwarts'. It takes the characters from the Mortal Instruments series and drops them into the world of Harry Potter. It shows how they adapt to the new magical environment, for example, Jace trying to understand Quidditch while also dealing with the threats in Hogwarts that are different from those in his own world.
In fanfic, they can blend in various ways. For example, the magic systems can be combined. The runes from 'Mortal Instruments' might be used alongside spells from 'Harry Potter'.
Sorry, I have no clue. It's possible that Mortal Instruments isn't a fanfic of anything and stands on its own as an independent work of fiction.
One great Harry Potter fanfic is 'The Life and Times' by Jewels5. It delves deep into the Marauders' era, exploring the backstories of James Potter, Sirius Black, Remus Lupin and Peter Pettigrew in a very detailed and engaging way. It gives a lot of insights into the Hogwarts of that time and how the events led to what we know in the original series.
A notable 'Harry Ginny Potter' fanfic is 'The Bond of Harry and Ginny'. This fanfic emphasizes the special bond that Harry and Ginny share. It begins with their early days of attraction and develops into a full - fledged relationship. The author does a great job of portraying Ginny as a strong and independent witch who complements Harry perfectly. There's also 'Ginny Potter: Her Story' which gives Ginny's perspective on her relationship with Harry, her family, and her life at Hogwarts, which is quite refreshing.
One great 'Harry Potter xReader Fanfic' is 'A Hogwarts Adventure'. It really makes you feel like you're part of the story. The author does an amazing job of creating scenarios where the reader character fits right into the magical world of Harry Potter. You get to experience the classes, the friendships, and even the battles alongside the beloved characters from the original series.
There's also 'The Hidden Dragon of Potter World'. This fanfic delves deep into the lore of dragons in the Harry Potter world. It tells the story of a dragon that has been hidden away for centuries and how it becomes intertwined with Harry Potter's journey. The descriptions of the dragon are really vivid, and it adds a whole new dimension to the familiar Harry Potter setting.
There's also 'Marriage Bonds in the Wizarding World'. This fanfic takes a more complex look at wizarding marriages. It features multiple characters' marriage stories, including Harry and Ginny. It shows how the magical bonds in marriage work and how they affect the characters' lives, with some interesting plot twists along the way.
One great 'Harry Potter Ginny' fanfic is 'Ginny's Year' which delves into Ginny's experiences during her years at Hogwarts. It really fleshes out her character and her relationship with Harry in a very believable way.
One great 'Harry Potter Slytherin Fanfic' is 'The Slytherin Heir'. It explores the life of a Slytherin student who discovers a hidden power within the Slytherin common room. Another is 'Slytherin's Redemption', which shows Slytherins in a new light, trying to break free from the negative stereotypes. And 'A Slytherin's Tale' is also good as it delves into the complex relationships among Slytherin students.
I really like 'The Great Duel Tournament Fanfic'. In this one, it not only has exciting duels but also delves into the backstories of the characters participating. It shows how their past experiences shape their dueling styles and adds a lot of depth to the story. There are also some really cool magical creatures involved in the duels which is a unique touch.
