Well, in this kind of fanfiction, a cool concept might be the powers that come with being the Son of Death. Maybe Harry has the ability to communicate with the dead in a more profound way than just using the Resurrection Stone. He could gain knowledge from them that helps him in his battles against Voldemort.
One interesting concept could be how the 'Son of Death' status affects Harry's relationships. For example, it might make his friends view him differently, with some being in awe and others being a bit afraid.
One interesting concept could be how Harry Potter's control over death might change the entire wizarding world's view on mortality. It could lead to a new era where people no longer fear death as much. For example, if he can control who dies and when, it might disrupt the natural order that has been in place for centuries in the wizarding world.
Well, in some 'Harry Potter after death fanfiction', there might be the concept of unfinished business. For example, a character who died before they could complete a certain task or mission might be given a chance to do so in the afterlife. Or perhaps the idea of a spiritual journey where the dead characters have to atone for their past mistakes. It could also be about the dead communicating with the living through dreams or special magical objects, which can add a whole new layer of mystery and connection to the story.
One interesting concept could be a fanfic where the Death Curse is reversed. Instead of causing death, it gives life in a strange way. Maybe it brings back characters who were killed by other means, but with some unforeseen consequences.

Some might be tempted to seek power from it, while others would be terrified and oppose it.
In 'Harry Potter Death and Reset Fanfiction', the reset aspect might lead to alternate timelines. The characters could have different fates or make different choices. For instance, if Voldemort was somehow reset to a point before he became so evil, it would be fascinating to see how the wizarding world would develop without his dark influence. This could also mean different Hogwarts houses having different relationships and rivalries.
In some 'Harry Potter Veil of Death' fanfictions, the Veil could be a portal not just to the afterlife but also to other times or places. For example, a character might accidentally pass through the Veil and end up in a different era of the wizarding world, like the time of the Founders. This can lead to all sorts of adventures and interactions with long - dead but important figures in the magical history.
Another aspect could be the character development. If a character becomes an Avatar of Death, it would change their personality and motives completely.

In some fanfictions, life after death might involve a sort of afterlife realm that is unique to wizards. It could be a place where they continue to study magic and grow in power. This realm might have its own rules and hierarchies, and perhaps only the most powerful wizards are able to traverse between this afterlife and the living world.
One interesting concept could be how Harry Potter's new role as the master of death changes the power dynamics in the wizarding world. For example, it might make him more feared or respected by other wizards.
