One of the highly regarded Lotr fanfics is 'The Redemption of Angmar'. It delves deep into the backstory of the Witch - king and creates a captivating narrative that stays true to the lore of Middle - earth. The characters are well - developed and the plot is full of twists and turns.
You can start by looking on fanfic platforms like Archive of Our Own. There, you can search for 'Lotr' and then sort by popularity or ratings. Another way is to join Lotr fan communities on social media or forums and ask for recommendations from fellow fans.
One great 'Game of Thrones' and 'LotR' fanfic I've read is 'The Convergence'. It combines the political intrigue of 'Game of Thrones' with the epic fantasy world of 'LotR'. The author weaves a story where characters from both universes meet and interact in a way that feels natural. It has some really cool battle scenes that are inspired by both works.
A lesser - known but excellent piece is 'Ringbearer Buffy'. Here, Buffy is somehow made into a ringbearer. It's a unique take on both franchises. The story delves deep into how Buffy's personality and her experiences as a slayer would affect her role in the quest to destroy the One Ring. It has some great character development and some really intense action scenes.
One of the great ones is 'The Grey Wanderer'. It beautifully weaves the magic of Middle - earth and the wizarding world. It has a unique plot where a character from LOTR somehow ends up in Hogwarts and the interactions between the two universes' elements are just amazing.
First, know both universes well. Read the books and watch the shows. Then, find an interesting concept to combine them. For example, you could have a character from 'LotR' travel to Westeros. Next, focus on the characters. Make sure their personalities are consistent with their original versions. Also, pay attention to the language. In 'LotR', the language is more archaic, while in 'Game of Thrones' it can be more gritty. So, find a balance when writing dialogue.
Well, you could do a lotr fanfic that focuses on the magic in Middle - earth. Maybe a story about a young wizard in training who stumbles upon an ancient and powerful spellbook. Or you could write about a fanfic where the orcs have a different origin story than what's in the original lore. Also, a fanfic set in a parallel Middle - earth where the Ring was never found and how the different races would have developed in that scenario.
One great 'LotR OC fanfic' is 'The Ranger's Apprentice'. It features an original character who becomes a ranger in Middle - earth. The story is full of adventure and mystery, with great descriptions of the landscapes and cultures. Another is 'The Elven Heir', which focuses on an elven original character's journey to discover their true heritage. It has beautiful language and really captures the essence of the elven race in LotR. There's also 'The Dwarven Forge', where an original character gets involved in the dwarven mining and forging traditions, and it shows a different side of Middle - earth.
One idea could be to have nanomachines in the Harry Potter universe that are secretly created by a dark wizard. They could be used to control the minds of students, but the protagonists discover this and use magic inspired by LotR spells to combat it. For example, a Patronus charm with a LotR - like incantation to repel the nanomachine - influenced dark magic.
