The goal is obvious: Discover the secret route and complete the maze. But the bickering guilds will never cooperate, and each sends its own champion to claim the prize. But Jace Beleren believes that the guilds are being tested. The maze hides some deeper truth, and Jace knows that the power balance of Ravnicaand the lives of its denizensare at stake. Jace's potential allies have been captured, disgraced, or turned against him. Can he discover the truth behind the maze, while navigating the labyrinth of powerbrokers and conspiracies surrounding it, before the dragon can? Or will dark forces claim its deadly power for themselves?
