What could be the plot of a 'Harry and Ginny child from the future' fanfiction?

Well, one possibility could be that the kids from the future come back to prevent a great disaster in the present. Maybe a dark wizard that was defeated in their time has somehow found a way to be reborn in the past (the present in the story), and they need to stop it before it's too late.

It could be a new dark wizard who has risen to power in the future and is trying to change the past to gain more power. This villain might be jealous of Harry's fame and Ginny's influence in the wizarding world, and by changing the past, they hope to rewrite history in their favor.

One possible plot could be that they see a future where the wizarding world is in great danger again. So they start to train young wizards secretly to prepare for the upcoming threat.

Perhaps the child is on a quest to bring back a lost magic that was present in the past but will be crucial for the future. Fred and Hermione are initially skeptical but as they see the child's abilities and the evidence of the disappearing magic, they start to believe. Together, they embark on a journey to find ancient spells and artifacts that can restore the magic, all while dealing with the challenges of time travel and the secrets the child holds.

Well, perhaps they will discover that magic has merged with Muggle technology in the future. Harry and Ginny could be amazed to find flying cars that are powered by both magic and electricity. They may also encounter new forms of dark magic that they have to fight against, or they might see a future where the wizarding world has achieved complete peace and harmony, and they play an important part in maintaining that peace.

One option could be time - travelers from a different future. Maybe there are some wizards from a parallel future who want to change the past to suit their own needs. They might be opposed to Harry and Ginny's kids because they are trying to protect the original timeline. These antagonists could use some really complex time - magic to try and outwit the kids.

One plot twist could be that Harry is actually protecting Ginny and the real father. He might know some dark secret about the father that would put them in danger if it were known, so he pretends to be in the dark about the situation.

One possible reason could be miscommunication. Maybe they had a big fight over how to raise their child and Ginny, feeling unheard, decided to leave. Another reason might be external pressure. For example, if some dark forces were targeting their family again and Ginny thought leaving would keep Harry and the child safer. Or perhaps Ginny had some personal issues she couldn't deal with while being in the family, like feeling she lost her own identity in the relationship.

In the future 'Harry Potter' fanfiction, the magical world could be on the verge of a technological - magical revolution. Magical devices are now integrated with Muggle - like technology. The new generation of witches and wizards, including those related to Harry, are at the forefront of this change. They have to balance the old magical traditions with the new advancements.

In this fanfiction's afterlife, Harry and Ginny might be in a place where time has no meaning. They could be constantly surrounded by a warm, golden light that represents all the love and positive energy they've created during their lives. They start to discover hidden powers within themselves that allow them to shape the afterlife realm. For example, they might create beautiful gardens filled with magical plants that only exist in their memories from Hogwarts. Their relationship becomes even deeper as they work together to make this afterlife place a haven for other souls.
