Fantacide is a term used to describe the deliberate and systematic act of killing or destroying imaginary beings or entities, often in the context of storytelling, gaming, or creative writing. It reflects the idea of eliminating characters or fantasy elements that are integral to a narrative, potentially leading to the collapse or loss of creative worlds. The term can also imply a critique of how certain narratives treat their characters or worlds, emphasizing the impact of such actions on the audience's engagement and emotional investment.
