What are some common themes in a disastrous necromancer novel?

Well, I'm not sure if it exactly fits the term 'disastrous' in the same sense, but 'Grimgar of Fantasy and Ash' has elements related to necromancy in a light novel setting. It's about a group of people in a fantasy world dealing with various challenges, and there are some dark magic elements which might be related to necromancy.

One well - known character type is the young and naive necromancer who starts off not fully understanding the consequences of their actions. For example, in some novels, there's a character like Elara who begins her necromantic journey innocently but soon realizes the horror she has unleashed. Another is the wise old necromancer who has seen the disasters caused by their kind and tries to either stop the younger necromancers or guide them in a better way. And then there are the anti - necromancer heroes, like the valiant knight Cedric who is dedicated to destroying necromancers and their undead minions.

One common theme is friendship. Since Saiki has a group of friends in the original show, fanfictions often explore their relationships deeper. Another theme is power management. Saiki has to constantly hide his powers, and fanfictions might show different ways he has to deal with that in new situations.

One common theme is the struggle between the dark nature of necromancy and love. Since necromancy is often associated with death and the undead, it creates a contrast with the life - affirming nature of love.

The concept of the afterlife is another common theme. Since necromancers deal with the dead, the nature of the afterlife, whether it's a peaceful place or a place of torment, and how necromancy affects it are often delved into. It might be that the dead are not supposed to be brought back, and doing so has consequences not only for the living but also for the dead's eternal state.

One common theme is the struggle for acceptance. Since necromancy is often seen as a dark art in the Harry Potter world, Harry usually has to face a lot of opposition from the wizarding community. Another theme is the exploration of power. Harry has to learn to control his new necromantic powers and not let them consume him.

One common theme is the struggle with identity. Since Fem Harry is different from the original male Harry, she has to deal with how society in the wizarding world views her as a female necromancer. Another theme could be the exploration of dark magic in a new light. Necromancy is considered dark, but in these fanfictions, it might be explored as a way for Fem Harry to gain power to protect herself or others. Also, there could be themes related to friendship and betrayal. Her friends might be scared or turned off by her interest in necromancy, leading to potential rifts in relationships.

Another theme is the idea of the 'forbidden'. Necromancy is often seen as something dark and taboo in these stories, and a romance with a necromancer is also considered forbidden, which adds to the tension and allure.

One common theme is the struggle against prejudice. Since Hermione is a Gryffindor in the original series, in these fanfictions as a Slytherin, she has to face the existing biases towards Slytherin house. And with her necromancy abilities, there's often the theme of the ethical use of such dark magic.

Power and its consequences. Necromancers often gain great power by controlling the undead, but this comes with a price. They are usually shunned by society, so there's a theme of isolation.
