Well, he could use it to uncover secrets that Dumbledore might have left behind. Since Dumbledore was a very knowledgeable and powerful wizard, his wand could hold the key to certain mysteries. Harry might be able to access hidden chambers or knowledge that was previously inaccessible. However, taking the wand could also bring a great deal of trouble. There could be those who would want to take the wand from Harry, thinking he doesn't deserve it or that it should be in their possession for their own dark purposes.
Maybe he takes it out of a sense of duty. Harry might feel that he needs to carry on Dumbledore's legacy and that using his wand is a way to do that. He could believe that Dumbledore's wand holds the power to defeat the remaining threats to the wizarding world.
I'm not sure specifically as I haven't read that exact fanfiction. But it could potentially be about Harry Potter having some sort of conflict with Dumbledore and taking actions against him. Maybe Harry discovers some dark secrets about Dumbledore that make him question his leadership and take steps to oppose him in the fan - created storyline.
Some of the younger students who looked up to Harry, like Neville, could support him. Neville has grown to be a strong and brave character. He might see Harry's actions as a way to make the wizarding world a better place. Also, those students who have felt wronged by Dumbledore's decisions in the past, perhaps in terms of school policies or safety, could come forward to support Harry in the court case.
Maybe in the fanfiction, there is a misinformation or a spell that has corrupted Dumbledore's mind. Harry, being the hero he is, notices the change in Dumbledore's behavior. He decides to take down Dumbledore because he thinks it's the only way to save the wizarding world from the new, dangerous path Dumbledore seems to be leading them on. For example, Dumbledore might be making alliances with dark forces unknowingly due to the spell, and Harry has to stop him.
One possible plot could be that Harry discovers some long - hidden secrets about Dumbledore's actions during the war. Maybe he finds out that Dumbledore knew more about Voldemort's plans but didn't act in a way Harry thought was right. So, Harry decides to take him to court to expose the truth and seek justice for those who suffered because of what he believes were Dumbledore's missteps.

Harry Potter's wand was made of holly wood, with phoenix tail feathers as the core. This wand, made by the famous wandmaker Garrick Ollivander, has a special connection to Voldemort's wand (made of ebony and dragon heartstrings), because they both come from the same phoenix tail feather. Harry's wand was about eleven inches long, and it was elastic, which made it very sensitive and accurate when it worked. This wand was very important to Harry, and it played a vital role in his fight against the Dark Arts.

Dumbledore himself could be seen as the main antagonist in this scenario. Since Harry is set on taking him down, Dumbledore's actions, whether they are truly malicious or just misinterpreted, would be the main obstacle for Harry to overcome.
One possible fanfiction could be about the origin of the Hydra Wand. Maybe it was created by a dark wizard who was inspired by the mythical Hydra. The wand could have special powers like being able to split into multiple smaller wands in a battle, each with its own unique spell - casting ability.
