The story revolves around a supernatural phenomenon known as "liminal spaces." These are "cracks" in the real world, usually found in abandoned places or locations marked by intense collective trauma, such as old hospitals, deserted schools, and apartment buildings where massacres have taken place. Those who enter face physical manifestations of their deepest fears and may be hunted by an entity called the "Shadow Weaver." Yet these spaces also contain fragments of the truth behind unsolved mysteries of the past. The protagonists must use their exceptional reasoning skills to solve the puzzles amid extreme terror, not only to survive, but also to uncover a vast historical conspiracy connecting the fates of countless people.
