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.
The trailer story of Shadow of War could be about the power struggle in the game's universe. It may feature the different factions vying for control. For example, we might see the hero trying to unite various groups against a common enemy, which could be a powerful and evil warlord. There could also be elements of betrayal and redemption as the story unfolds within the trailer.
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.
In most cases, it is legal. Fanfiction is a form of creative expression by fans. As long as it doesn't violate any copyright laws in a major way, like using the exact same footage from the trailer without permission in a way that undermines the original work's marketability. But if it's on a legitimate platform that respects intellectual property, you should be okay.
The God of War Ragnarok trailer shows Kratos and Atreus facing new challenges. It seems they are up against powerful foes as they continue their journey in the Norse world. There are epic battles and a sense of impending doom as Ragnarok approaches.
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.
A third theme could be loyalty. There may be scenes in the trailer that show characters being loyal to each other or having their loyalty tested in the face of the war's challenges.
