Luna Lovegood could be a main focus. Her unique perspective on magic could be used to discover new magical phenomena that emerged after the battle. She might also be helping the other students deal with their post - battle stress, using her calm and dreamy nature to soothe them.
Well, a plotline might revolve around the new relationships that form. For example, Neville could start a herbology club and meet a new love interest who is also passionate about plants. Also, the wizarding world might see some political changes. Maybe there would be a new Ministry of Magic with more inclusive policies after the dark times of Voldemort's regime.
One great post apocalyptic Harry Potter fanfiction is 'The Shattered World'. It presents a dark and desolate world after a magical cataclysm. The characters have to fight for survival in a way that's very different from the original series. Another one is 'Surviving the Ruins' which focuses on how the Hogwarts students band together against new and terrifying threats.
After the battle, Harry was weary but his eyes lit up when he saw Ginny. She ran towards him, and they embraced tightly. There was a moment of pure silence as they held each other, all the fear and chaos of the battle fading away. Harry whispered 'I'm so glad you're okay' and Ginny just nodded, tears in her eyes.
In their post - battle reunion, Harry and Ginny experience a complex range of emotions. Relief is the most obvious one. Harry has been on the front lines, facing death at every turn, and Ginny has been worried sick about him. So when they see each other, it's like a breath of fresh air. Love is also there in abundance. They embrace passionately, their love for each other stronger than ever. But there's also a tinge of sadness. They've both lost friends in the battle, and this reunion is bittersweet. However, overall, the positive emotions of love and relief overshadow the sadness as they look forward to a future together.
Yes, there are likely fanfictions out there that combine elements of Harry Potter and the Battle of Helms Deep. Fanfiction writers often like to mash up different fictional universes. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own.
Maybe Neville could be a central figure. He has always been strong and determined. In a post - apocalyptic world, his skills in Herbology could be extremely valuable. He could be in charge of finding or creating new plants that can provide food, medicine, or protection against the new threats in the world.
One interesting concept could be the rebuilding of Hogwarts. After an apocalyptic event, the once - great school might be in ruins. The remaining wizards and witches could come together to restore it, using their magic in creative ways. They might have to find new sources of magical energy or deal with dark magic that has been unleashed during the apocalypse.

With the world in chaos, some characters may find hidden strengths within themselves that they never knew existed before, which helps them in their fight for survival.
