Well, perhaps Harry stumbles upon the Mandarin's rings in some unexpected way. Maybe he's on an adventure and discovers them in a hidden lair. Then he has to figure out how to use their power without falling under their negative influence.
The plot could involve Harry being in a situation where he is given the Mandarin's rings. He might initially be clueless about their true nature. As he starts to explore their powers, he could face challenges like other characters trying to take the rings from him. He would then have to use his wits and skills, along with the new powers of the rings, to overcome these obstacles. It could also lead to him having to make some tough moral choices regarding the use of such powerful artifacts.
Obviously, Harry is one of the main characters. And since it involves the Mandarin's rings, the Mandarin himself might be a significant character, either as an antagonist or as someone who has a connection to the rings that Harry has to figure out.
Maybe Harry discovers long - lost relatives who come forward after the war. For example, a distant cousin could show up and welcome him into their family. They might share stories about his parents that he never knew.
The staff could be a key to an entirely different form of magic. Harry, upon obtaining it, has to learn a whole new set of skills. It might have the power to control elements, like fire, water, earth and air. With this new power, Harry is not only stronger in his battle against the dark side but also becomes a more well - rounded wizard. He may face challenges in learning to balance the use of his wand and the staff, but in the end, it makes him a more formidable opponent to his enemies.
Well, it could be that Naruto somehow discovers the power of Obelisk the Tormentor. Maybe he stumbles upon an ancient relic or meets a mysterious figure who bestows this power upon him. Then he has to learn to control it, which might be really difficult as Obelisk the Tormentor's power is extremely potent.
One common theme is power. The mandarin rings often hold some sort of power, and the characters in the fanfiction either seek to gain it or have to deal with the consequences of its existence. Another theme could be mystery, as the origin and true nature of the rings are usually not fully known at the start.
One possible plot development could be Harry using the Deathly Hallows in unique ways to defeat Voldemort more quickly. For example, he might use the Elder Wand's power more effectively to counter Voldemort's dark magic. Another could be his exploration of the Cloak of Invisibility's deeper magic, like being able to pass through magical barriers undetected. And with the Resurrection Stone, he could have conversations with the dead that provide crucial knowledge about the Horcruxes or Voldemort's weaknesses.
His friends like Ron and Hermione could be part of it. They've been through so much together, and after the war, they might decide to live close to each other and consider each other family. They could raise their children together and share holidays as one big family.
He could be a protector. Just like the elves in Lord of the Rings are often guardians of their realms, Harry could use his elf - like abilities to safeguard a particular place or group of people in the fanfiction.
A fanfiction with the basilisk in the Lord of the Rings universe could lead to some amazing plotlines. The basilisk is a magical creature from the Harry Potter world, known for its deadly stare. In Lord of the Rings, there are different forms of magic and power. If the basilisk were to appear, it could change the power dynamics. For example, the wizards in Middle - earth like Gandalf might have to figure out a way to deal with it. It could also be a part of some prophecy or ancient lore that the characters have to uncover. This would make for a really engaging and unique fanfiction that combines two very different but equally beloved fictional worlds.
One common plot device is the transfer of Harry's knowledge from the wizarding world to Middle - earth. For example, she might use her knowledge of potions to create new substances in Middle - earth. Another is her being an outsider who has to prove herself. Just like in the Harry Potter series, fem Harry has to gain the trust of the LOTR characters. And often, there's a plot about her finding a new purpose in Middle - earth, something that ties her to the fate of the Ring.
