In fanfiction, one reason could be his desire for a fresh start away from the memories at Hogwarts. Maybe he feels he has done all he can there and wants to explore new magical knowledge elsewhere.
Perhaps in some fanfictions, Snape leaves Hogwarts because of a conflict with other staff members. For example, if there are new policies or power struggles that he doesn't want to be part of. He's a proud and solitary character, so he might choose to leave rather than submit to something he doesn't agree with.
Another possible reason is related to his past. He has a complex and often troubled past. Fanfiction might depict him leaving Hogwarts to confront his past demons directly, away from the place that constantly reminds him of his mixed experiences. Maybe he wants to find out more about his family history or deal with his old associations in a more private setting.
One possible reason could be that he feels he has fulfilled his purpose there. Maybe he has achieved certain goals related to protecting Harry Potter secretly, and he decides it's time to move on to other things. For example, in some fanfictions, he might leave to explore his own family history or to further his research on the Dark Arts in a more secluded place.
One reason could be to search for a powerful magical artifact outside of Hogwarts that they believe is crucial for defeating a new dark threat. In fanfiction, they might feel that Hogwarts has become too dangerous or restricted in terms of resources for their mission.
Maybe he leaves because of a conflict with the Hogwarts staff. If the new headmaster or some teachers start implementing rules that Harry believes are wrong or unfair, like restrictions on defensive magic classes, he might decide to leave in protest.
One reason could be that the writer wants to create a new plot twist. Maybe Snape's character has fulfilled its purpose in the fanfiction's storyline and his quitting can lead to new developments for other characters.
In fanfiction, Snape might punish Draco for getting involved with the wrong crowd. For example, if Draco starts to associate with Death Eaters - in - training or those with malicious intentions. Also, if Draco fails to complete his academic tasks or cheats in exams, Snape would surely take action. This is because Snape values knowledge and academic integrity in Hogwarts. Additionally, if Draco causes trouble during important school events or ceremonies, Snape would likely punish him to set an example for other students.
One possible reason could be a shift in their loyalties. Maybe they discover some dark secrets about Harry or the side he represents that make them uncomfortable. For example, if they find out that Harry has some hidden motives that go against their own beliefs or values.
Yes, he is. Fanfiction often delves deeper into the idea of Severus Snape's connection to Hogwarts. Since he dedicated his life to the school in different ways in the original story, fanfic creators expand on this. They might write about him being magically bound to Hogwarts, where he can't stray too far from the castle grounds. This could be because of a spell he cast himself, or as a result of some ancient magic related to his role at the school.
One possibility could be that Snape grows up in a different magical environment, perhaps in a small, hidden magical community that has its own unique way of teaching magic. He might develop his skills in potion - making and the Dark Arts in a more self - taught or community - guided way. Without the influence of Hogwarts, his relationships would be very different. He may not have the same intense rivalries or unrequited love for Lily Potter.
There could be an excess of alternate universes. Fanfictions often create all kinds of wild AUs for Snape. Maybe he's tired of being in so many different scenarios that don't really stay true to his essence. For example, some AUs make him a modern - day rock star or something completely out of character.
He might leave Hogwarts in fanfic due to a sense of disillusionment. Maybe he discovers some dark secrets about the school or the wizarding world in general that make him question his place there. It could be something related to the way the school is run or a conspiracy among the teachers that he stumbles upon.
