There could be some old and wise wizards or witches from outside of Hogwarts who come to help. Maybe they heard about Harry's heroics in the battle and feel obligated to use their ancient magic knowledge to save him. And, of course, Ginny would be by his side, using her love and determination to will Harry back to health.
Well, perhaps it could be about Harry being seriously injured during the Battle of Hogwarts. His friends might be scrambling to find a way to heal him. Maybe Hermione would be frantically searching through all her books for a healing spell while Ron stays by Harry's side, constantly worried.
I remember a fic where Harry and Draco end up on the couch post - battle. It was called 'Aftermath on the Couch'. The story delved into how their past rivalries still lingered but also how the shared experience of the battle made them realize they had more in common than they thought. It was really interesting to see how the author developed their relationship in that small, intimate setting of the couch.
Harry's first emotion on seeing Ginny after the battle was pure astonishment that they had both survived. This quickly turned into an overwhelming sense of love and protectiveness. Ginny was feeling elated yet also a bit shaken. She had been through a lot during the battle, and seeing Harry safe made her feel like she could finally let go of the fear she had been holding onto. Their reunion was a cauldron of emotions, with happiness, relief, and a deep - seated love for each other being the main ingredients. As they hugged, they both felt like they had come home to each other in the middle of all the post - battle chaos.
After the battle, Harry was exhausted but his eyes were searching for Ginny. Finally, he saw her among the crowd. Their eyes met and in that instant, all the chaos around them faded. Ginny ran towards Harry, and he opened his arms wide. They hugged tightly, not saying a word at first, just feeling the warmth and relief of being together again.
Mystery can be a theme too. In some fanfics, the cause of Harry's injury is a mystery that he has to solve. This adds an element of intrigue and keeps the readers hooked as they try to figure out what happened along with Harry.
In many fanfics, after the battle, Harry and Ginny's relationship often deepens. They finally have time to truly be together without the constant threat of danger. They might start to plan their future, like getting married and starting a family. Ginny, being the strong - willed witch she is, would support Harry in his post - battle endeavors, whether it's helping to rebuild Hogwarts or dealing with the psychological trauma of the war.
In many Harry Potter fanfics, life after the last battle often involves a time of rebuilding. The wizarding world has to repair the damages done during the war. Characters might focus on restoring Hogwarts to its former glory. For example, they would fix the broken walls and bring back the lost magic within the castle. There could also be a period of healing for those who lost loved ones. They would come together to support one another and find ways to move forward.
He might focus on rebuilding Hogwarts. After all the destruction, it would be a huge task and he could use his influence and skills to bring it back to its former glory.
