[Card strategy + contests of law and principle + world mysteries + territory management + the rise of the cardless + archaeological investigations + brooding suspense] The good news: He transmigrated to a world built on cards. There is no System, no status screen, no sign-in rewards handing him divine cards. But he discovers that he can "hear" the echoes of history deep within the cards. The truths altered and erased by the Sacred Contract Bureau are sealed inside every discarded old card as memories of living people.
The bad news: He is cardless. In this world, where cards determine social status, the cardless don't even have the right to stand on someone else's land. Anyone who fails to bind a birth card during the awakening ceremony, held between the ages of twelve and fifteen, belongs to the three percent of the population deemed useless and relegated to society's lowest rung. He is one of them.
