Dark Necromancer Harry Potter Fanfiction: What are some interesting plot ideas?

A possible plot for 'Harry Potter as a Necromancer' fanfiction is that there is a hidden necromancy school within Hogwarts that only reveals itself to those with the true potential for necromancy. Harry stumbles upon it and is drawn into a world of dark magic and secrets. He has to learn how to control his necromantic powers while also dealing with the internal struggle of whether this magic is truly evil or if it can be used for good. His friends might be divided in their opinions, with some supporting him and others fearing his new abilities.

One possible plot idea could be the Dark Prince having a hidden agenda that not even Voldemort is fully aware of. He might be secretly manipulating events to gain ultimate power for himself. For example, he could be using the chaos of the wizarding war to his advantage by making deals with both sides without their knowledge.

One idea could be exploring how the Dark Mark affects the mental state of those who bear it. For example, it might cause nightmares or hallucinations related to Voldemort's will. Another could be a story about a character trying to hide their Dark Mark from their friends in the Order of Phoenix, creating a lot of internal conflict and secrecy.

One idea could be that Harry discovers a dark secret about his family that leads him down a dark path. For example, he might find out that his ancestors were involved in some really evil magic and he starts to explore that side of magic. Another could be that the influence of Voldemort somehow remains and corrupts Harry's mind over time. Maybe the Horcrux inside him wasn't completely removed and it starts to change his way of thinking.

One idea could be that Harry, influenced by dark magic, forms an uneasy alliance with Voldemort. They could team up to take over the wizarding world in a different way than Voldemort originally planned, perhaps by ruling jointly. Another plot could involve Harry exploring the darker aspects of his own magic and using some of Voldemort's knowledge to do so, which causes a rift between him and his friends.

One interesting plot idea could be a story where a student discovers a long - lost dark arts spell book in the Forbidden Forest and has to resist the temptation to use the powerful and dangerous spells within it. This could lead to a battle between good and the allure of the dark arts within themselves.

In some of these fanfictions, Harry might start exploring the dark art of necromancy secretly. He could be driven by a desire to bring back his lost loved ones, like his parents. This often leads to him having to hide his newfound interest from his friends at Hogwarts, creating a lot of internal conflict as he struggles between what he knows is right and his longing for his family.

Dumbledore, if he were still alive, would be very cautious. He would try to guide Harry towards using his powers for good, or at least in a way that doesn't disrupt the balance of the wizarding world. The other Hogwarts professors would likely be split. Some would be horrified and want to expel Harry, while others would see it as an opportunity to study a rare form of magic and its implications.

In a dark fanfiction, Voldemort could have placed a dark spell on Harry long before he knew. As Harry grows, the spell starts to take effect, making him darker. Luna, being an outsider in many ways, notices the changes in Harry. She decides to research ancient magic to find a way to break the spell. Along the way, she discovers secrets about her own family's magic that could be the key to saving Harry and the wizarding world from the impending darkness.

One idea could be that Harry gets the Dark Mark by accident and has to figure out how to hide it from his friends. Maybe he discovers that the mark has some unexpected powers that he has to learn to control.
