Ten years ago, a mysterious “Rift to the Void” appeared in Xinhai City, splitting the sky above the metropolis. The rift brought supernatural powers, and gave rise to “Resonants,” who had to pay a cruel “price” to use them. In this transformed world, the government’s “Order Bureau” tries to maintain a fragile balance, the radical “Awakening Front” preaches evolution, and the secret society known as “the Ark” searches for the rift’s ultimate truth. Xinhai City has become the eye of a storm, with multiple factions vying for power.
