What are some interesting plot ideas for 'Lord of the Rings harem fanfiction'?

Perhaps the gamer could start a new fellowship, not to destroy the One Ring but to study and preserve the magic within all the rings. They could travel across Middle - earth, gathering knowledge and artifacts related to the rings, facing challenges from both Sauron's forces who think they are trying to undermine their plans, and from those who fear the power of the rings being misused.

One idea could be that the OC is a healer who joins Aragorn's journey. They meet during a battle where Aragorn is injured and the OC uses their unique healing skills to save him. This starts a bond between them as they travel together, with the OC providing medical aid to the whole fellowship.

One idea could be that the Dragonborn from Skyrim somehow ends up in Middle - earth. Maybe they are mistaken for a powerful wizard due to their Thu'um abilities. Another plot could involve the One Ring being found in Skyrim and the different factions vying for its power, just like in Middle - earth. A third interesting plot would be characters from Lord of the Rings traveling to Skyrim and having to deal with the cold, the dragons, and the political unrest there.

One idea could be to explore what would happen if Frodo was accompanied by a magical creature that could sense the Ring's power and help him resist its allure better. This creature could be a new creation specific to the fanfiction.

One idea could be that the characters from Middle - earth accidentally stumble into Narnia through a magical portal. For example, Aragorn and Legolas could find themselves in the middle of the Narnian forest and team up with the Narnians to fight a common enemy, like an ancient evil that threatens both worlds.

One idea could be that the vampires from Twilight are drawn to the power of the One Ring. They might see it as a source of great power that could enhance their abilities. Another plot could involve a character from Twilight getting transported to Middle - earth and having to adapt to the new world while also dealing with the threat of Sauron. Or perhaps the werewolves from Twilight could form an alliance with the Ents in Middle - earth, as they both have a connection to nature.

One idea could be that Bilbo Baggins discovers a hidden relic during his adventures in 'The Hobbit' that later becomes crucial in the fight against Sauron in 'The Lord of the Rings'.

One idea could be exploring the backstory of a minor character in the game. For example, a Uruk-hai who has a change of heart and decides to fight against Sauron's forces instead. It would add an interesting twist to the existing lore.

One idea could be a story about a young Gondorian soldier who discovers a long - lost artifact that holds the key to an ancient Gondorian power. He must then protect it from enemies both within and outside Gondor.

A crossover with the Star Wars universe would also be cool. The Jedi could be like the wizards in Middle - earth. Maybe Aragorn could learn some lightsaber skills from the Jedi and use them against the orcs. And the Force could have an interesting interaction with the magic in Middle - earth.
