Disease could be a factor. Maybe in this fanfiction, a new, highly contagious and deadly disease spreads among the troops. Since soldiers are in close quarters, especially in trenches, camps, and on ships, it would spread rapidly. This could decimate the ranks of both sides and lead to far more deaths than in the actual World War 2.
One reason could be the alteration of major battles. For example, if in the fanfiction the D - Day invasion fails catastrophically, it would lead to a huge number of Allied deaths and a shift in the war's momentum towards the Axis. This would likely cause a domino effect, with more battles resulting in heavier losses as the Allies struggle to regain the upper hand.
One reason could be more intense battles. For example, in a fanfiction scenario, if certain key battles like Stalingrad or Normandy had been even more fiercely fought. Maybe the Axis powers had stronger defenses or the Allies had less effective strategies initially. Another aspect could be the introduction of new and more deadly weapons earlier in the war. This could lead to higher military casualties on both sides.
The post - war world in such a fanfiction would likely be more devastated. Economically, it would take much longer to recover. With more deaths, there would be a shortage of manpower to rebuild industries and infrastructure. For example, countries like Germany and Japan that were rebuilt after the real World War 2 might struggle even more in this fictional scenario.
The post - war world would be much more devastated. Economically, more military deaths would mean a greater loss of human resources. Countries would have a harder time rebuilding as there would be fewer able - bodied men (and women in some cases) to contribute to the workforce. For example, the rebuilding of Europe would be far more challenging.
The possible reasons in the Burari deaths real story are complex. Superstition seems to be a big factor. The family might have been influenced by some local or self - created beliefs. Also, there could have been some psychological factors at play. Maybe they were in a state of collective delusion. They seemed to be following a set of rules or instructions that were not based on rational thinking, as seen from the evidence of the writings in the house.
In some cases, he could be leaving in search of a greater purpose. He might feel that there are things he can learn or achieve outside the wizarding world that will ultimately help the wizarding community more. He may also leave because of some prophetic vision or a feeling that he doesn't belong there anymore, that his path lies elsewhere, away from the familiar magical realm he grew up in.
One possible reason could be miscommunication. Maybe Harry made a decision during the post - war rebuilding without consulting Ginny, and she felt left out or disrespected. For example, if he agreed to some dangerous mission without telling her.
One possible reason could be a misunderstanding over resources. Maybe there's a new chakra - rich area discovered near the border and both villages claim it. Another reason might be the actions of a rogue ninja from one village being wrongly blamed on the other, causing tensions to escalate.
It could also be that Harry himself is so traumatized by the war that he isolates himself. He might push people away, thinking that he's a danger to them. As he withdraws, others might misinterpret it as him not wanting their company and gradually abandon him.
One possible reason could be that the fanfiction writer wants to explore a different side of Hermione's character. Maybe in this version, Rowle has some hidden qualities that Hermione finds appealing, like a unique sense of humor or a deep understanding of magic that she hasn't seen before.
Perhaps in the fanfiction, James is seen as more accepting of Lily's friends and her social circle. Snape, on the other hand, might be associated with a darker crowd or have some beliefs that Lily doesn't agree with. For example, if Snape is too involved with the Dark Arts in the fanfiction, it could be a turn - off for Lily.
