Farmers in fantasy fiction can be portrayed in various ways. Sometimes they are the unsung heroes. They can be the ones who first notice strange happenings in the fields or with their livestock, which could be signs of a greater magical or evil force at work. They may also be the ones who maintain ancient traditions related to the land, and these traditions could hold the key to solving a big mystery in the story.
In fantasy fiction, farmers are often depicted as simple and hardworking folk. They usually live in rural areas, close to the land. They might be seen as the backbone of the more 'mundane' part of the fantasy world, providing food for the villages and towns. Their clothing is often plain and practical, and they may have a deep connection to nature, which could sometimes be magical in the context of fantasy.
Well, in fantasy fiction, farmers are usually an integral part of the world - building. They can represent the common people who are affected by the actions of the more powerful characters like wizards or knights. For example, if a dark sorcerer is causing droughts, it's the farmers who suffer the most. Their huts and small farms add to the rustic charm of the fantasy landscape. And some farmers might have a latent magical ability that they are unaware of, which could be discovered during the course of the story and change their lives completely.
