In 'Whose Shadow Is That?', players take on the role of Harper, a curious historian who stumbles upon an ancient artifact that blurs the line between reality and fantasy. The artifact allows Harper to interact with shadows—not just any shadows, but those of historical figures who have drastically shaped the course of history. As Harper explores their past, they must unravel a conspiracy hidden within the shadows and confront a sinister entity that seeks to rewrite history for nefarious purposes. Each interaction with a shadow provides choices that affect both the narrative arc and the historical world, leading to multiple endings based on the players' decisions.
