Set in Florence, Italy during the height of the Renaissance, the story casts the player as a devoted apprentice to the legendary inventor and artist Leonardo da Vinci. When the great master mysteriously vanishes, the apprentice begins searching for him, starting within the walls of Da Vinci's own house. Room by room, they must unravel an intricate web of ingenious mechanical contraptions and physics-based puzzles, reverse engineering the genius's inventions to uncover clues about where he has gone. Along the way, the apprentice discovers two extraordinary lenses granting supernatural sight: one reveals hidden codes and secrets concealed in plain view, while the other peers into the past to witness events that have already unfolded. Guided by cryptic letters left behind by Da Vinci, and shadowed by unseen adversaries with their own designs, the apprentice ventures deeper into the master's world of art, machinery, and secrets in pursuit of the truth.
