A common secret is about a character's true identity. Maybe a seemingly ordinary student is actually a long - lost heir to a powerful wizarding family. Another one could be a secret about a magical creature. For example, a fanfiction might have a secret about a group of unicorns that have a special power.
One common type of secret is related to the Forbidden Forest. In fanfiction, there could be a hidden area deep within it that holds a great secret, perhaps a powerful magical object or a portal to another dimension. Also, secrets about the Ministry of Magic are popular. For example, a secret plot within the Ministry to control certain aspects of the wizarding population.
One of the secrets could be about hidden relationships between characters. For example, a secret friendship that was never shown in the original books but explored in the fanfiction.
In some fanfictions, the Weasley family might have a secret connection to a powerful magical artifact. This could be a well - kept secret within the family for generations, and it might be revealed in a time of great need. For example, it could be related to the origin of their red hair which has some special magic property. Another family secret could be that the Malfoy family has a long - hidden plan that involves the Potter family, not just the obvious enmity. There could be a secret pact or something in the past that is gradually uncovered in the fanfiction world.
A common secret could be a character's true heritage. For example, a character might be secretly related to a powerful noble family or a long - lost elven clan. Another example is a secret alliance. A group of characters might be secretly working together against a common enemy without the knowledge of the main characters or the ruling powers in the fanfiction.
Well, one hidden secret could be the true nature of some magical creatures. In fanfiction, we might find that thestrals have a deeper connection to the afterlife in the wizarding world than we thought. Maybe they are not just seen by those who have witnessed death, but they also play a role in guiding lost souls.
A hidden secret might also lie in the relationships between different wizarding families. There could be long - held grudges or alliances that are not fully explored in the official books. Fanfiction can unearth these secrets, like a feud between two families that has been going on for centuries but has been kept quiet from the general wizarding public.
There could be a secret chamber in Hogwarts that no one has found yet in fanfic. This chamber might hold ancient magic or the key to a powerful spell. It could be hidden by powerful enchantments and only a select few characters, perhaps those with a special connection to the founders of Hogwarts, might be able to discover it.
One secret could be about the true nature of certain magical artifacts that were only hinted at in the original books. For example, the Marauder's Map might have deeper secrets like how it was enchanted to show not just the castle but also hidden passages that lead to other magical realms.
One idea could be exploring the backstory of the Chamber more deeply. Maybe look into how Salazar Slytherin really built it and what his true intentions were beyond just getting rid of Muggle - borns. Another could be a story where a new student discovers a hidden passage within the Chamber that leads to an even greater mystery. For example, they might find an ancient spellbook that has the power to change the very fabric of Hogwarts.
In Harry Potter fanfic, one travel secret could be the use of hidden Portkeys in unexpected places. For example, a seemingly ordinary pebble on a deserted beach might be a Portkey to a magical location only known to a select few in the fanfic. Another could be secret passages within the Forbidden Forest that lead to different parts of the wizarding world, like a hidden village of magical creatures.
In a Harry Potter Chamber of Secrets fanfiction, you could have a story where the Marauders (James, Sirius, Remus, and Peter) had a connection to the Chamber that no one knew about. Maybe they left behind some clues or magical items in the Chamber that Harry and his friends find. Or a plot where the Chamber is not just in Hogwarts but has a connection to other wizarding schools around the world. A new character could come from one of these schools to help Harry deal with the threat of the Chamber. Additionally, a fanfiction could explore what would happen if the Sorting Hat had a more active role in the events related to the Chamber. It could give Harry some special advice or power to face the challenges inside the Chamber.
