Well, silo fan fiction is basically when fans of the 'Silo' concept or story write their own stories related to it. They might be inspired by the unique setting of the silo, the mystery within it, and the characters' struggles. For example, a fan might write a story about a character's backstory that was only hinted at in the original. It allows fans to expand on the existing universe and put their own creative spin on things.
In a more symbolic sense, the concept of a silo can represent isolation or containment. For instance, in a business context, when departments are described as 'working in silos', it means they operate independently without much communication with other departments. This can have both positive and negative impacts on the overall functioning of an organization. If departments are too siloed, it can lead to inefficiencies and lack of innovation as ideas don't cross - pollinate. However, in some cases, a certain level of siloing can be beneficial for focused work within a particular area.
A silo based on novel might be a silo that is described in a very specific way in a novel. It could be a physical silo, like a grain silo on a farm in a rural - themed novel. Or it could be a more symbolic silo, representing isolation or containment in the context of the story's themes and characters.
A silo can be important in a novel as a setting. It can create an atmosphere of isolation, like in a horror novel where a character is trapped in a silo. It also might be a place of mystery, full of secrets waiting to be discovered.
