Midgard fiction books often have richly detailed worlds. They usually include different races, like elves, dwarves, humans, etc. For example, in 'The Lord of the Rings', these races co - exist and interact in the world of Middle - earth which is similar to midgard. Another characteristic is the presence of magic or some sort of supernatural elements.
Hidden Midgard in a Tony Stark Avengers fanfiction could be a really cool concept. It might be a parallel dimension of Earth that has a connection to Asgard or some other alien realm. Tony Stark, with his curiosity, might be the first to suspect its existence. He could then use his Iron Man suit and all his tech gadgets to find a way to access it. Once there, he might find new allies or enemies, and this discovery could change the course of the Avengers' battles and their overall story.
The heroes like Thor and Loki could be great. Thor is strong and has a sense of justice. His presence can bring a lot of action and heroic deeds to the story. Loki, on the other hand, is full of trickery and can add twists and turns.
Ordinary people with extraordinary hearts. These could be farmers or simple villagers who show great courage in the face of danger. They can represent the common folk of Midgard. Their stories of survival and resistance against the odds can be really inspiring and can add a touch of realism to the otherwise fantastical story.
I'm not sure as the term'secret chest' is rather ambiguous without more context. It could potentially be a special box or container with a secret related to it in the context of the story.
The following were some recommendations for the long novels about tomb raiding: Tomb Raider's Mountain Guardian, Tomb Raider's First Sign in as Mountain Guardian, Tomb Raider's Master, Tomb Raider's Concubine: The Emperor, Gently Flirting, Tomb Raider's Journey Starting from the Palace of Lu, and Tomb Raider. These novels covered different storylines and styles to satisfy readers 'interest in tomb raiding.
Maybe in the fanfiction, Hidden Midgard is a parallel dimension on Earth. Tony Stark accidentally stumbles into it. There, he meets different versions of his friends and enemies. He has to figure out how to get back to his own world while also dealing with the political and power struggles within Hidden Midgard.
Sure. 'The Lord of the Rings' is a great midgard - like fiction book. It has a vast and detailed world - building, with various races and epic battles. Another one could be 'A Song of Ice and Fire'. It presents a complex political and social landscape in a fictional world, full of interesting characters and unexpected plot twists.
