In a world where light and shadow aren't just visual phenomena but actual sentient beings, players find themselves as The Treader, an agent who possesses the unique ability to interact with shadows. Your mission is to delve into the meandering streets of a city where shadows of the past hold the key to solving a series of mysterious disappearances tied to a sinister figure known only as The Harbinger. Engage in emotional dialogue with shadows, solve perplexing puzzles, and navigate through a narrative filled with morality, betrayal, and the haunting question: who really controls the shadows?
