No. 'The Lord of the Rings' was not a Cold War novel. It was written long before the Cold War era, with Tolkien starting to write it in the 1930s. Its themes are mainly centered around good vs. evil, heroism, and the power of friendship, which are more in line with classic fantasy and moral concepts rather than being related to the political and ideological struggles of the Cold War.
No. Tolkien began writing LOTR in the 1930s and was influenced by his study of mythology, his experiences in World War I, and his own moral and religious beliefs. The Cold War started much later, and there is no evidence that Tolkien was thinking about Cold War politics when creating Middle - earth.
One common theme is the struggle for power. In both the LOTR universe and Shadow of War, power is a central aspect. Fanfics often explore how characters from different sides deal with the allure and danger of power.
One interesting storyline could be about a group of overlooked heroes in the North who form an alliance to fight off a new and unexpected threat that the main characters in the original LotR didn't face directly. They might discover ancient magic or weapons that change the course of the war in the North.
Often, original characters that are strong warriors are popular. For example, a human ranger who has extraordinary archery skills and a deep knowledge of the Northern lands. He could be a lone wolf type character who joins the fight against the dark forces.
There's a fanfic called 'Across the Realms' that is really good. In this 'Shadow of War LOTR crossover fanfic', it delves deep into how the different magic systems from both work together. The plot is full of twists and turns, and the way the author weaves the two worlds together is quite engaging. It also explores the relationships between characters from the two different franchises, adding a layer of depth to the story.
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.
Sesshomaru's speed and agility would be a great asset in Middle - earth. He could easily outrun orcs and other foes. His sword, Tenseiga, which has the power to resurrect, could also have an interesting impact. For example, if he were to use it on a fallen hero, it could change the course of a battle.
One idea could be that the One Ring somehow ends up in the world of Pirates of the Caribbean. Jack Sparrow, being the wily character he is, gets wind of its power and decides to either use it for his own gain or sell it to the highest bidder. The Fellowship, in turn, has to track it down in this strange new world full of pirates, sea monsters, and cursed treasures.
Lotr has a huge fan base already, and when you add the element of vine fairies, it's like opening a new door to creativity. Writers can create all sorts of scenarios where the fairies interact with the hobbits, dwarves, etc. It gives a fresh perspective on the well - loved Lotr world.
