Grimdark is a subgenre of speculative fiction characterized by its bleak, morally ambiguous settings and themes. It often features a world where traditional notions of good and evil are blurred, and characters face harsh realities, making difficult choices for survival. This genre is prevalent in literature, film, and tabletop games, with notable examples including Warhammer 40,000 and the works of authors like George R.R. Martin. In grimdark narratives, hope is often scarce, and protagonists may be antiheroes or flawed individuals. The tone is typically dark, emphasizing violence, betrayal, and despair. This style appeals to audiences seeking complex stories that challenge conventional heroism and explore the darker aspects of human nature.
