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.
A 'disastrous necromancer' in light novels can also be the result of a curse or some ancient magic gone wrong. Maybe they were an ordinary mage who dabbled in necromancy without fully understanding it. And then something unexpected happened, like they became linked to a powerful and malevolent force that forces them to raise the dead against their will. This uncontrollable aspect makes them 'disastrous' as they are constantly causing trouble, whether they want to or not. Their story then becomes about trying to break free from this curse or control while also dealing with the chaos their undead creations are causing.
One common theme is the moral ambiguity of necromancy. Since raising the dead goes against the natural order, it often leads to a conflict between the necromancer's desires and what is considered right. Another theme could be the power struggle. The necromancer might face opposition from other magic - users or the general populace who fear their power. Also, the idea of unintended consequences is prevalent. The act of necromancy can unleash unforeseen disasters like uncontrollable undead creatures causing chaos in the world.
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.
I'm not entirely sure as I haven't read it in full. But generally, a 'lone necromancer' theme might involve a character who is a necromancer and perhaps on some sort of solitary journey. It could be about his adventures in a world where necromancy is either feared or revered, facing challenges and enemies while using his necromantic powers.
Sadly, I don't have the information regarding the author of this 'boundless necromancer light novel'. It could be a relatively new or niche work, and not widely known in terms of its author yet. You might need to search in specialized light novel databases or forums to find out.
Well, 'boundless necromancer light novel' could be about a journey of a necromancer in a world full of magic and mystery. The 'boundless' part might suggest that there are no limits to what the necromancer can do or discover. It could involve battles against those who oppose necromancy, or the necromancer's quest to master their powers even further.
I'm not sure as I haven't read this specific light novel. But generally in necromancer - related stories, themes like death, the afterlife, and the power over the undead are common. There might also be themes of morality as necromancy often goes against the natural order.
Obviously, the lone necromancer is a main character. There might also be an antagonist, perhaps someone who opposes the necromancer's use of dark magic. And there could be a sidekick or a mentor figure, someone who either helps the necromancer understand their powers better or tries to lead them onto a different path.
