I'm not certain, but given the title, it would be reasonable to assume that the main character is the Midnight Guardian. However, it could also be a story where Harry Potter himself has some sort of connection to this Midnight Guardian and they share the spotlight as main characters.
Since I haven't read it, I can't say for sure. But it's likely that the main character is the Midnight Guardian.
The 'Midnight Guardian' might be a reincarnation of an ancient wizard. In some fanfictions, old magic and past heroes can be brought back in new forms. So this 'Midnight Guardian' could be a hero from the past, reborn to protect the present - day wizarding world, especially at midnight when threats lurk in the shadows. They could have unique powers and knowledge that are crucial for the safety of the magical realm.
I'm not sure specifically as I haven't read it in detail. But generally, a Harry Potter fanfic might be about new adventures in the wizarding world, perhaps introducing new characters like the 'Midnight Guardian' and their role in the fight against dark forces or in protecting Hogwarts.
Well, 'Midnight Guardian' in Harry Potter fanfiction might refer to a self - appointed or magically - bound entity. It could be a magical creature that has the task of guarding a certain area or secret at midnight. Maybe it's a phoenix that appears only at midnight to protect a hidden prophecy or a powerful magical artifact. Without reading the specific fanfiction, it's hard to say exactly what it is, but it's often something unique and exciting in the world of fan - created Potter stories.
Luna Lovegood often becomes an extremely interesting character in these fanfics. Her unique view of the magical world can lead to some really cool midnight escapades. For instance, she might lead Harry on a midnight search for a rare star - related magical object that is only visible at midnight.
It might be a Hogwarts professor. A professor who is dealing with some personal issues and the'midnight blues' are a sign of their inner turmoil. This professor could be the main character as they discover something strange happening in the castle at midnight. Their knowledge of magic and the school would be put to the test as they try to figure out what's going on and keep the students safe.
There could be a midnight story where Harry accidentally travels back in time during a midnight stroll in the castle. He ends up in the time of the founders of Hogwarts. He has to interact with them without changing the future too much. This gives him new insights into magic and how Hogwarts was built, which he can use to strengthen the defenses of Hogwarts in his own time.
Severus Snape is likely to be a main character as it is often his perspective that is explored in a 'Midnight Sun' - style fanfiction. His complex personality and his relationship with other characters in the Harry Potter universe make him a central figure.
Obviously, Harry Potter is the main character. He is the one taking on the role of the guardian. Hermione and Ron usually play important supporting roles as well. They help Harry in his mission to protect Hogwarts with their knowledge and skills.
A potential guardian could be Sirius Black's spirit. Even though he died, his love for Harry could be so strong that it allows his spirit to act as a guardian. He could appear to Harry in times of need, give him advice, and even use his limited spectral powers to protect Harry from minor threats.
It could be his mother, Lily. Her love was already a powerful protection for Harry, so in the fanfiction, it could be her spirit acting as a guardian angel, using her love to shield him from harm in a more direct and continuous way.
